How Do I Diagnose This SSL Error?

The following steps will help you diagnose the SSL errors you receive in Chrome.Firstly, after going to the site which generates the error, press the F12 key to bring up the Chrome DevTools. Select the Security tab item to see more about the certificate and the SSL connection:If there's a problem, it will be highlighted in Red. In this case, the certificate is signed with the weak, deprecated SHA-1 algorithm:If the error complains about the certificate in some way, you can click on View Certificate to get more information. For example, it's good to check the Certification Path to make sure the certificate appears to be legitimate:If you'd like to learn what effect the different "bad" configurations will have on Chrome, you can explore the sites from Bad SSL:

I followed the suggestions in this discussion for diagnosing a client-side SSL error, but I don't know how to interpret the result.

The openssl command for www.plex.tv returns a good certificate. But when I try to login at Chrome strikes out the https and shows "Not Secure." I get an error message when I proceed to login. This happens on Firefox as well as Chrome, and it happens from any computer on my home network. I am able to login from an android phone over the cellular network.

FYI I ran the SSL command on a Synology NAS which also runs on my home network.

If it was an ISP problem, wouldn't the openssl command return a bad certificate?

Can Someone Send Popup Message to All Mobile Network Users?
Yes and no.From a mobile phone on AT&T, Verizon, O2, etc., to other mobile phones on the same network, no. That would be a bad idea.Network operators have the ability to send certain kinds of alerts to all mobile users in an area. These alerts are Amber alerts (US) and emergency (flash flood, gas leak, etc.)Can you detect all users in the same network cellular or mobile network as you?Is it possible to send SMS or broadcast popup message from your mobile phone to other mobile users in your proximity?
How Big a Role Does Brand Value Play in Determining the Price of a Product?
Brand is a signal of quality of the product. For example; a famous brand such as Apple for cellular phones will cost more because consumers have a belief (based on previous purchase, market ratings, and word of mouth etc.) that it has better quality and features compared with a similar cellular phone which is not of famous brand. Consumers are willing to pay a higher price for the higher quality (vertical differentiation due to brand value of Apple). The exact value of brand has always been a focal point of debate by experts in marketing and price pundits. Brand value does play a significant role in price of the product only if the consumers perceive a brand value and their willingness to pay is affected by this. There are different ways to price such as cost plus based pricing and willingness to pay based pricing. Typically cost plus pricing does not factor the brand value as it is not a direct cost to company. If a company is doing willingness to pay based pricing then brand value must play a big role, but willingness to pay based pricing is not easy due to limited data on consumers. How big a role does brand value play in determining the price of a product?1. Why couldn't cellular phones prior foment the political revolutions that the Internet is presently fomenting?It's not the technology that foments revolution. It is the people. Iran already had a revolution in 1979, a rather unfortunate one as it turned out. They did it without cell phones. Next time they will do it with cell phones, when historical conditions are right.2. Files Transmission using Media Transfer Protocol (MTP)In this article we will describe what Media Transfer Protocol (MTP) is, as well as its advantages and disadvantages. The MTP protocol seeks to address concerns about the distribution of digital content in the consumer market as an increasing number of organizations create and distribute digital audio/video content. The aim of MTP is to deliver content via a secure, easy-to-use interface, and push it to a range of devices. The Media Transfer Protocol, introduced by Microsoft, is a protocol designed for intelligent storage devices like phones and digital audio players. It is based on, and fully compatible with, the Picture Transfer Protocol (PTP). MTP allows the synchronization of files between portable devices and a personal computer (PC). Standardized in 2000, PTP was originally developed to transfer images from a digital still camera to a PC. PTP is limited to transferring images and is an insufficient solution for media rich portable devices like phones and portable media players. Microsoft therefore introduced the MTP to address the shortcomings in PTP. Before the development of MTP, mobile phone manufacturers integrated USB Mass Storage Class (USB MSC) into their products to facilitate file transfers between PC and phones. However, since the standardization of MTP as a Universal Serial Bus (USB) device class in 2008, manufacturers have slowly started moving towards implementing support for MTP in their devices. MTP offers the following advantages over USB MSC: A smartphone device in MTP mode controls the input and output to the file system. Hence there is no risk of data loss in case of accidental or intentional disconnection from USB of the host computer. MTP also prevents formatting of the smartphone's partition as users are only working on a layer over the file system, thus providing a greater degree of lock-down. Unlike MTP, USB MSC works at a block level. This means when a phone with this protocol is connected to a PC system, it gives the host computer absolute control over the phone's operating system partition. This can lead to serious consequences, for example, it would be possible for the host to reformat the file system in the phone. As the MTP driver uses a simulated file system, it is always compatible with any host computer regardless if the operating system of the host supports the file system or not. With USB MSC, the host PC must support the USB MSC file system natively or download drivers for it to be compatible. MTP is closely related to Windows Media Player and supports copyright protection through digital rights management (DRM). USB MSC does not have any support for DRM. USB MSC prevents the PC and device from accessing itself at the same time. With USB MSC, the phone device is locked by the host computer while it is being accessed. Users trying to use their phones during this period will not be able to. MTP does not suffer from such issues and allows simultaneous usage by the host computer and the user. Thus, the user could make calls, check SMS messages while the phone is performing file transfer to and from the PC. Let us now turn to some of the disadvantages of using MTP: Files on a MTP device cannot be directly viewed or altered. They must first be copied to the host computer before it can be opened. Large files will take a much longer transfer time which can be very inconvenient to the user. MTP can only perform a single operation (read, write, delete, etc.) each time and other operations cannot be executed without completing the current running operation first. File timestamps are often read-only and set by the device after a file is uploaded to it. SyncBack uses a number of strategies to get around this limitation. MTP devices are mounted as Windows portable devices. Thus, they show up as an entry in Windows Explorer with no drive letter issued. Software trying to connect to these devices via drive letters will not be able to do so. One example would be the old versions (pre-V7) of the backup and synchronization software, SyncBackPro, SyncBackSE and SyncBackFree. Android devices like phones and tablets with the MTP protocol will have no drive letters allocated to them and the old versions of SyncBackPro/SE/Free will not be able to perform data backups or synchronization to or from these devices. However, SyncBackPro and SyncBackSE V7 and newer support MTP (it is not supported in SyncBackFree). In conclusion, the Media Transfer Protocol (MTP) is a class protocol for current and future portable media devices like portable media players and cellular phones. An alternative to using MTP is to install SyncBack Touch on the device. There are many advantages to using SyncBack Touch instead of MTP.3.

Frequently Asked Questions (FAQ) for Cellular Phones
1. What are the advantages of using mobile handheld devices? What are the disadvantages?A handheld computing device has an operating system (OS), and can run various types of application software, known asapps. Most handheld devices can also be equipped with Wi-Fi, Bluetooth, and GPS capabilities that can allow connections to the Internet and other Bluetooth-capable devices, such as an automobile or a microphone headset. A camera or media player feature for video or music files can also be typically found on these devices along with a stable battery power source such as a lithium battery. Increasingly mobile devices also contain sensors like accelerometer, compass/magnetometer andgyroscope allowing detection of orientation and motion.nHandheld devices have become ruggedized for use in mobile field management. Uses include digitizing notes, sending and receiving invoices, asset management, recording signatures, managing parts, and scanning barcodes. nRecent developments in mobile collaboration systems employ handheld devices that combine video, audio and on-screen drawing capabilities to enable multi-partyconferencing in real-time, independent of location.nHandheld computers are available in a variety of form factors, including smartphones on the low end, handheld PDAs, Ultra-Mobile PCs and Tablet PCs (Palm OS,WebOS)nUsers can watch television through Internet on mobile devices.

Most casinos have a play for free option. nIn the military field, mobile devices have created new opportunities for the Army to deliver training and educational materials to soldiers around the world.nSource for a2a...What are the advantages of using mobile handheld devices? What are the disadvantages?------2. What do you guys think should be done about Price Tag Attacks?Thanks for A2AnIn my opinion, those crimes should be investigated and the guilty parties should be brought to justice - whether they are Jews or Arabs. As I already wrote on the subject, while it's extremely flattering to the public ego, that Jews were able to enter an Arab village in the middle of the night, to commit arson and to leave without anyone being the wiser - it's also extremely unlikely. There are dogs in the villages and most of them are outside pets. And none barked? Read Sherlock Holmes "The Adventure of Silver Blaze". They barked, but the frightened villagers (who think that they got "tagged" for throwing stones) were too afraid to go out & check? Forgive my French: Bullshit. This is what happens to Jews in the enemy village/city: 2000 Ramallah lynchingnI am not saying that it's impossible, that Jews did it. We have our own crazies. After all, there were these guys: Jewish UndergroundnBut, as I said, in the unlikely case, that these are Jews, I demand that the conditions of their punishment/imprisonment would be identical to those of Arab terrorists:nPA is paying to rebuild the houses of families of Arab terrorists that Israel demolishes. While demolishing Jewish home would not help in the prevention (collective-oriented Arab society vs individual-oriented Jewish one), something drastic *should* be done. I suggest that the government would confiscate the house and'd pay for the new house built outside of Judea & Samaria. nWhile in jail, the Jewish terrorists should have free education, free medical care and visits from the families (conjugal visits included). Internet access, special foods and cellular phones - comes without saying. nWhen Arab terrorists'd be released as a concession, because of Ramadan or in exchange of Jewish soldier captured by an Arab terrorist group, so'd some of the Jewish terrorists be released - one Jew to ten Arabs sound fair enough. Like Arab terrorists, the Jewish terrorists should sign a document of promise never to repeat terrorist activities after which, unless they'd break their promise, any discrimination against them would be illegal.What do you guys think should be done about Price Tag Attacks?------3. Are we at risk of allowing the progression of science and technology to lead to great damage to humanity much like religion has in the past?Technology is based on our continued understanding of nature and the discovery of new scientific principles, which can be applied to help enhance and extend our lives. All technology has a purpose. Generally, the ultimate uses for specific technologies is virtually impossible to predict. Let me provide some examples. The airplane had both a commercial and military use from its beginning. While nuclear energy was specifically developed for a wartime purpose, it has enjoyed more usage in the commercial electric power generation sector. Integrated Circuits were initially used in missile guidance and military computer systems and now have widespread usage in both commercial and military systems. Microwaves radiation was developed to enhance the resolution of Radar, and while it continues to serve that purpose it is widely used in microwave ovens. GPS was developed for battlefield positioning and again while it is used in highly accurate munitions, it has also found widespread usage in cheap commercial navigation systems and cellular phones. Electromagnetic technologies are widely used in both military and commercial wireless systems. However, their use in electromagnetic weapons threaten some of society's most important infrastructure elements (for example the electrical grid). Likewise, information technologies have become pervasive in our increasingly complex and interconnected infrastructure, but their use in cyber weapons threaten that very infrastructure. Breakthroughs in biological technologies could lead to more effective cures of genetic diseases and the possibility for extending life. However, their potential use in biological weapons could spread unknown strains of highly contagious diseases. I would say just about every technology I can imagine has the potential for both constructive and destructive purposes. The challenge in some of the newer biological/information technologies is the potential for their malicious "viral" spreading in ways unimaginable by their creators. A good book on the evolution of technology is Brian Arthur's, The Nature of Technology: What It Is and How it Evolves. One of the interesting observations (actually he states it as a general rule) Arthur makes is "every technology contains the seeds of a problem, often------4. Who is the most intelligent criminal in history? Why?I saw Frank Abagnale on this list and was very satisfied with that answer as Frank was one of the first pioneers in Social Engineering, even before the invention of the modern home PC. One might argue though that the smartest criminal was the guy that followed in Franks footsteps and became a legend among hackers. That man is no other than.Kevin Mitnick.I mean after all, this is his business card (later in life after released from prison)At age 13, Mitnick used social engineering and dumpster diving to bypass the punch card system used in the Los Angeles bus system. After he convinced a bus driver to tell him where he could buy his own ticket punch for "a school project", he was able to ride any bus in the greater LA area using unused transfer slips he found in a dumpster next to the bus company garage. Social engineering later became his primary method of obtaining information, including usernames and passwords and modem phone numbers.Mitnick first gained unauthorized access to a computer network in 1979, at 16, when a friend gave him the phone number for the Ark, the computer system Digital Equipment Corporation (DEC) used for developing their RSTS/E operating system software. He broke into DEC's computer network and copied their software, a crime for which he was charged and convicted in 1988. He was sentenced to 12 months in prison followed by three years of supervised release. Near the end of his supervised release, Mitnick hacked into Pacific Bell voice mail computers. After a warrant was issued for his arrest, Mitnick fled, becoming a fugitive for two and a half years.According to the U.S. Department of Justice, Mitnick gained unauthorized access to dozens of computer networks while he was a fugitive. He used cloned cellular phones to hide his location and, among other things, copied valuable proprietary software from some of the country's largest cellular telephone and computer companies. Mitnick also intercepted and stole computer passwords, altered computer networks, and broke into and read private e-mails------5. How to ensure users can't sign up for multiple accounts?This is a tough issue that I'm not sure anyone has really solved yet, but here are my thoughts for your 3 solutions.Yes this might be a bit personal or creepy but I feel like it's becoming less so since people are actually using their phones less and less. You'll want to be clear that you're not selling their phone number to a marketing agency or they won't be receiving any solicitations. Also for this to be effective, you will have to verify that this is in fact their phone number meaning a text message confirm or something to that effect to prevent people from putting in some random phone numbers they don't own.The cons for this are pretty big issues so I wouldn't recommend this. What I might recommend for this is to use the IP address private email domains to alert you to suspicions of a multiple accounts in which you can investigate. Obviously working with the threshold of this would be useful.CC number is complicated... you generally do NOT want to be storing CC numbers since it creates a huge liability for the company. As such you normally use some sort of service which provides a token, and suddenly thing become very complicated. Unless you need to set this up anyways for payment of your service, this can be a lot of work. That being said, CC is not a bad idea if you really want to only have people who are a bit more committed to your product to actually go and give it a try. Also to increase comfort levels, you can potentially not ask the for their CCV (i'm not sure if this will screw up validating the authenticity of the numbers).I honestly don't feel that having just email will cause absurd amount of freeloaders to continuously use trials. Also someone who's doing that will most likely never buy your service anyways (or is not the kind of customer you want), however without knowing what your service is exactly it's hard to say. Out of the 3 you have here I probably recommend phone number.
5 Ways Equity Crowdfunding Can Benefit Society | Ethis Blog
Technology has come into our lives to better the human condition. It has easily and evidently improved our lifestyle, from cellular phones, limitless access to all sorts of information and its involvement in the advancement of infrastructure, transportation, and science. In the world of finance, the adoption of Fintech has fostered a digital economy of easy, on-demand transactions and transfers, transforming business communication and reducing administrative costs. Beyond efficiency, Fintech has also arrived in the form of new models for finance and investment, such as equity crowdfunding (ECF). This model leverages on human capital to fund all manner of projects, including for Small and Medium-Sized Enterprises (SMEs), startups and even property. Equity crowdfunding helps issuers companies and entrepreneurs who are seeking capital, by matching them to investors who are seeking investment opportunities. Since crowdfunding platforms are online and serve communication and transaction purposes to mitigate the process, this matching is done with great efficiency and transparency, and potentially on a large scale across borders.At a deeper level, equity crowdfunding has brought a multitude of significant benefits that may not be apparent to the casual observer. Lets take a deep-dive into the emerging world of Equity Crowdfunding, and explore a few key merits of this game-changing fintech model. 1) Financial InclusionFinancial inclusion is a central approach towards a sustainable financial system and a vital factor for healthy socio-economic development. Today, there is an acute shortage of funding for SMEs and startups. On the other hand, the high minimum ticket sizes and requirements for those seeking investments have resulted in the exclusion of a large portion of society from actively participating in the capital markets. The ordinary investor is typically only able to invest through unit trusts and the like, which limit funds circulation to the financial and stock markets, not to the real world of small and medium businesses, and almost never to micro-businesses and startups. More impactful investments outside of listed stocks are usually made through fund managers and investment houses, which serve large sophisticated investors and other institutions, with a minimum investment out of the reach of most people. Such fund managers, although with a wider and more open appetite for alternative investments, do not commonly allocate much investment in SMEs or new businesses. Equity crowdfunding has a major role to play in changing this status quo. The online and decentralized nature of Equity crowdfunding platforms creates wide reach, potentially bringing funds to those who had been left out. Since the decision on where the money goes to is now in the hands of the many, there is a greater propensity for it to go to businesses that are familiar or attractive to the masses, from social enterprises to innovative startups. Popular equity crowdfunding campaigns by SMEs and startups can raise enough capital to kick start new businesses or provide funds for important projects, giving a chance for these businesses to grow and reach a scale where they can compete confidently in the open market. At the same time, Equity crowdfunding is characterized by its open and democratic nature, allowing virtually anyone with some extra money to invest, as long as they reach the minimum threshold which is in most cases just a few hundred dollars.2) Job OpportunitiesThe advancement in technology has rendered many jobs from across every industry obsolete. The finance industry is also hard-hit, where digital or mobile-only financial services disrupt the traditionally infrastructure-heavy brick-and-mortar financial institutions. For almost every traditional job, there is a digital counterpart, for example, through E-sports, you can actually make a career out of playing video games. For sure, post-graduation employment is not what it used to be. According to the European Commission Entrepreneurship 2020 action plan, New companies, especially SMEs, represent the most important source of new employment. In Europe and the U.S, research demonstrates that almost all net job creation is accredited to startups and new businesses. What these SMEs and start-ups depend on to grow is funding which is not readily accessible through banks and other traditional avenues. Equity crowdfunding comes into the picture to fund these companies, to support their vision, leading to growth and more employment. The nature of equity crowdfunding platforms being flexible and open to new ideas and in many cases new models increases the survival rate of such business and averages their growth rates. In addition to more jobs, there is also a greater variety of jobs in the market. 3) Market GrowthIn times of economic slowdown or recession, small businesses and entrepreneurs are most vulnerable, equity crowdfunding comes in with fresh capital, injecting funds into a drowsy economy from non-typical sources and generating new revenue. For investors, it features diversified investments in asset classes beyond the conventional ones, allowing them to own equity in exclusive and unique businesses. For businesses, it is easily accessible, global and markedly effective, helping them stay afloat, stay motivated and compete with larger corporations. This does not only apply to early-stage businesses but also includes well-established companies for expansion, increasing reach and identifying potential customers. Furthermore, Equity crowdfunding platforms are transparent and centralized and can be great in reducing fraud. As more funds circulate through platforms, more quality businesses come on board, creating a virtuous cycle of growth. It is not unlikely that fraudulent projects may also seek to grab a slice of the crowdfunded pie, posing a threat to this thriving funding ecosystem. To safeguard investors, platforms perform screening and verification of projects before they are featured, ensuring high levels of transparency and disclosures which will scare off would-be fraudsters. There is also the wisdom of the crowd, where out of a large number of investors, there will be those who can sniff out and spot dubious projects. 4) Environmental Effects and SustainabilityGoing green, biodegradable straws, planting trees today, all types of campaigns are launched fighting for the environment. Previously, environmental concern was not a big issue, but today, the planet has rebelled against the capitalist plunder of nature, raising red flags with climate change hitting hard. This has sparked quick action towards sustainability. So does equity crowdfunding really play a role in this? In many ways, yes it does. Equity crowdfunding is done through the internet, it dramatically cuts off the traditional resource-intensive process of fundraising and investment which includes seminars and talks, physical meetings and transmuting to banks and institutions, to just a few clicks on the screen. It is characterized by easier transactions, a variety of campaigns, and a vast connection to like-minded networks. Plus, it is growing daily and beginning to attract global market players, raising awareness on a mass scale for the call of sustainability.Additionally, as we have learned the hard way, environmentally inclined businesses often barely survive and hardly reach a significant scale. For too long, people just did not care. Lets face it, it took us years and years of pushing just to downgrade the type of plastic used in plastic bags. In this field, equity crowdfunding platforms play a vital role as a space that actualizes environment-friendly businesses with funding and provides them with a united front of passionate investors backing their cause, keen to make an impact. Furthermore, equity crowdfunding platforms are global platforms that are able to reach projects in rural and underdeveloped areas, benefiting agricultural productivity and reducing poverty levels in the long run.Ethis is launching its first equity crowdfunding platform in Malaysia in early 2020. The platform is the first to receive an Islamic ECF License from the Securities Commission (SC) Malaysia. Ethis always seeks to feature ethical and impact-driven projects that provide healthy returns to our investors.5) The Sectors InvolvedThe main benefit for startups and SMEs lies in the quick raising of capital which is potentially easier to obtain than through Venture Capitals and bank loans. Additionally, issuers get capital from issuing shares while still maintaining management of their own business. Raising funds through equity crowdfunding platforms serves these companies by assisting them attract new investors to increase their probability of business success. A successfully funded and concluded campaign gives great validation and proof of concept for the company, eventually opening up follow-on investments from Venture Capital and institutional investors. On the other hand and beyond the money, crowdfunding investors are characterized by their passion and selectiveness in choosing business. This means that once a business is chosen, it is more than just making money but also about supporting and believing in the cause, gaining the business a community of avid supporters.In summary, equity crowdfunding brings 5 significant benefits to society. Central to this is the ability of equity crowdfunding being an attractive proposition for investors, by giving investors a range of new investment choices, allowing for active selection and diversification of their investment portfolios. The best part is that it is done through the internet, reducing the hassle of traditional investing. Investors can join a community of like-minded individuals from around the world to assist the growth of a project that they support. Additionally, there are no criteria for investing and low minimums for investors which makes it available for all income levels.Originally published at on December 17, 2019
Problems of Phased Array Ground Penetrating Radar Detection System
Although GPR has been widely used in hydrology, engineering, environment and other fields, many basic theoretical and technical problems have not been fundamentally solved, so the real advantages of GPR have not been brought into full play.The main problems existing in GPR technology include:1) The detection depth is shallow, and the contradiction between detection depth and resolution cannot be overcome. Increasing detection depth means sacrificing detection resolution;2) Multiple spread and other clutter jamming are serious, and there has been no good elimination method, which exists in radars at home and abroad;3) The influence of medium unevenness is great and can not be eliminated, resulting in difficulty in obtaining necessary velocity data;4) The data collection method of single sending and single receiving can provide limited information for post-processing and interpretation.The above problems are fatal defects for GPR. Although many geophysicists, electromagnetic experts and geophysical workers have done a lot of research and improvement on radar antenna design, signal processing and underground target imaging, these works are only partial modifications to the existing GPR system. In order to develop GPR technology, we must update our ideas and solve the problems from the fundamental principle.In view of this situation, experts proposed to develop a new GPR system - phased array GPR detection system in 1999.The basic research idea is to replace the current monopole radar antenna with the phased array radar antenna by using the relatively mature military phased array radar technology. Its purpose is to gather the electromagnetic wave into a narrow beam to transmit underground (or detection object) through the phased array technology, and receive the radar echo signal reflected by the target by using the multi-channel acquisition technology, The advanced data processing is carried out, and finally the three-dimensional image of the internal structure of the detection object is given.Development prospect of ground penetrating radar technologyIt is worth noting that at present, similar products have appeared in the market, such as RIS antenna array series of a company, but these products simply combine multiple monopole antennas into array antennas, which is essentially different from the idea of phased array ground penetrating radar.Because the phased array radar converges the electromagnetic wave into a narrow beam by controlling the phase delay of each channel, the energy is concentrated and the wave front diffusion is small. Therefore, the detection depth of the phased array radar is much larger under the condition of the same frequency and transmission power; On the contrary, under the same detection depth, phased array radar can improve the transmission power, so its resolution is much higher than the existing radar. In addition, since the spherical wave transmission is changed to beam transmission, the influence of medium heterogeneity is much smaller.Secondly, the phased array radar works in a continuous scanning mode and can scan in multiple directions. Therefore, the amount of information is much larger than that of the existing ground penetrating radar. For some special detection work, such as the quality detection of embankment cut-off wall, its role is unmatched by the existing ground penetrating radar (monopole antenna radar can not detect the joints, forks and other defects of embankment cut-off wall at all).Because phased array radar is a multi-channel received signal, multi-channel superposition can be carried out, just like the multiple coverage technology of reflection seismic exploration. Therefore, multiple interference can be greatly eliminated, which is difficult for existing radars. The antenna of high frequency (600mhz-1ghz) phased array ground penetrating radar can be made smaller, and its advantages are unmatched by the existing ground penetrating radar in shallow detection.At present, the system prototype has been completed. The carrier free pulse working system with center frequency of 900MHz is adopted, and the transmitting and receiving antennas are separated. 16 (4 × 4) Transmit channel forming, beam aggregation and scanning 16 (4) × 4) The channel receives the echo, and the optional scanning angles are - 36 °, - 24 °, - 12 °, 0 °, 12 °, 24 ° and 36 °.The software part of the system has rich data processing functions. The main conventional processing includes filtering, gain adjustment, static and dynamic correction, deconvolution, complex signal analysis, time-frequency analysis, etc., and multi-channel data processing, such as velocity analysis, superposition technology, coherence analysis technology, array signal processing, etc. And weak signal extraction, target automatic recognition and inversion interpretation under various clutter interference. A large number of field experiments on concrete detection in Yichang Three Gorges dam are carried out. The experimental results show that the spotlight scanning function of phased array radar has been realized, the penetration depth is greater than 1.5m and the resolution is higher than that of ordinary radar.Editing: hfy
Suggestions for Journaling, Bullet Notes, Activity, Wiki Like Application
So I am thinking of a possible answer to my own question:Build my own journal note entry app linked to a wiki.Zim Wiki uses a file based system for wiki. Maybe I could write app to export/sync entries in its files. Or WikkaWikki uses a MySQL (which is probably what I would use for journal entries anyway) so perhaps use same DB for Wiki and journal, with Journal app "doing right thing" to enter/sync Entries in wiki.Does this seem like a good approach?Or maybe I can customize a wiki with existing plugins - "All" I really need is good journaling / date feature, time tracking, checklist, and tags. Perhaps there already are plugins for this?Please comment if you have feedback on this idea.1. Circular tag wiki excerptsTag excerpts should at least try and give a concise definition as to the subject, and provided any usage guidance if necessary.Therefore, you need to make sure to address a set of key points:In general, excerpts should provide at least some guidance, even if it may appear to be ridiculously basic. Therefore, interpretation of the rejection reason is critical:That's like saying, [abs]: For questions about [abs] filaments. That should probably be rejected. This is better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use.Or even better: [abs]: For questions about [abs] filaments - filaments that are used with blah blah printers, and are not toxic for use. Not to be confused with [pla] filaments. Do not use this tag if your question does not concern this filament specifically. Obviously, I have no idea if abs is even a thing. Anyways, I hope this helps :)2. Why is this answer a community wiki?Apparently the answer under scrutiny was made CW because it drew on an answer from another Stack site, and the answerer wanted to share it without being associated with it for good or for ill.But community wiki is not a tool for reputation denial (or for dodging the repercussions of questionable-quality answers) and practically speaking I see no difference between quoting a different Stack and quoting a blog or a book. We would never expect someone to eschew rep for quoting a blog or a book. The answerer went to the trouble of tracking down the information and sharing it; why should not rep gains should reflect that?The moderation team is under no obligation to revert the CW in this case, nor are they obligated to leave it be, but I would lean toward reverting it myself, for reasons which follow.We've talked about posting answers from other sites, and it's pretty clear this is not cheese.Community wiki used to be massively overused. Changes to the editing system rendered its original purpose largely moot, and there's now a lot of confusion about CW's role in the Stack mechanics. These days there are three basic reasons to use CW:I do not see this particular answer needing CW to make it "easier to edit and maintain by a wider group of users," so I do not see any reason for it to be a community wiki. Community wiki is a tool with a specific set of uses, and CW rollbacks are left to mod discretion. One of the responsibilities of our moderators is to help the community use the right tools for the job at hand.As for the answer itself--it's not very good by lit.se standards, because it was written for a different site with different priorities. And the question itself is under a tag whose implementation is still being debated, so quality there is... in flux, I suppose we could say. We need to bring in our own expertise and tailor the answer to meet the expectations of our own Stack.3. Need to Change Edit Approval Limits for Tag Wiki EditorsI just upped it from 3 to 5. Hopefully this alleviates the issue a bit. If we still notice a pattern of users being blocked we can look at adjusting further4. Difference between Wiki Library and Document LibraryYes there is difference, Below might be helpful to understand.Document library can contains documents, it can be any document like office documetnts doc,xls,ppt, js, css, jpg, png etc...any file extension you can think of. Main purpose of document library is to store documents. wiki library is a kind of document library which contains wiki pages, Wiki pages are html pages with rich text editing capabilities so that users can create pages using Rich Text Editor without knowing html in detail. So when wiki library template is selected it comes with some default columns created based on content type, this columns are useful to create wiki page. Making changes and edits in a wiki page is incredibly easy. Just click on the edit button (at the top of the page) and immediately the page appears as an editor's version of the page. You can then make edits straight away and simply hit save. The page will instantly be up and running with your changes in place.
How Many NCAA Football Bowls Are There?
About 8 I think1. where can i get ncaa football 10 rosters with names?For the last two years I got mine from "Pastapadre". From what i can tell they are really pretty accurate. Give it a shot2. where can I watch NCAA football games for free?...?Try channelsurfing.net. They pick up a lot of justin.tv stuff, and they have loads of ncaa football games, free, no spam, etc. I watch all the time with no problems3. Can you download a team on NCAA Football 10's Team Builder using a flash drive?Why would you want to do that? Build your own team. Do not take the wussy way out.4.

I want to do a dynasty in NCAA Football 14 what team should I use (I want it to be a challenge like a weaker)?Vanderbilt, they are in a great conference and are already headed in the right direction as far as getting better and it will be a challenge because you will be in the SEC7. does ncaa football deserve a playoffs instead of bowl games being based off of BCS rankings?Whether or not the NCAA deserves a playoff does not matter. They do not want one so they do not have one. Frankly, the national championship playoff debate is a joke. This is something created by sportswriters and tolkshow hosts for the sole benefit of sportswriters and talkshow hosts. The NCAA does not recognize a national champion of the FBS so any discussion about who should or should not be the champion is pointless bloviating. Win your conference. Beat your rivals. Go to a bowl game. Those are the only things that matter in college football.8. What was determining the NCAA football title like in pre-BCS years?Hawaii, is not a very reliable team, yet might desire to win the Sugar Bowl in simple terms as surely as Georgia as a results of fact their offense constantly performs like its at the back of and it wears down the protection whilst they might desire to conceal the whole field. The unfold offense is the excellent offense in college soccer. It supplies much less gifted communities liek Hawaii and Illinois a gamble to beat far extra gifted communities. that's alsovery risky, that's why some exceptionally ranked communities dont run it. Hawaii surely did no longer deserve a identify shot in simple terms as a results of fact Boise State gained The Fiesta Bowl. Boise beat a BCS convention team who complete 10-4(Oregon State who beat USC and Hawaii in Hawaii) Hawaii has no high quality wins and does not deserve a NT shot. ending undefeated might desire to get you a BCS sport nevertheless9. NCAA Football 2009-What Defense to run online?Usually the defense package that comes with the team you are using as the best combo of players are on the field10. Which Championship/Playoff Picture needs more work....the NFL or NCAA Football?everybody keeps blaming the computers, but the computers are pretty much the only good part about the BCS, it only counts as 1/3 anyways. another 1/3 is coaches, former players, former athletic directors and people like that, the other third is the media. a lot of voters admitted to not even watching a utah game until they played alabama, how messed up is that. so lets put the blame where it really belongs, the stupid voters, who do not educate themselves about what or who they vote for11. could an NCAA football team beat a weak pro team?No-NCAA teams always have weak links and for the most part are BOYS.NFL teams have chosen the best of the best,and are MEN12. What teams rush the ball the most in ncaa football?its either navy or army one of them thats pretty much all they do13. What D1-AA teams are in NCAA Football 08?Usually they are. Just check out some of the SEC teams schedules. You find a lot of them there. Looks like the truth hurts down there!

Your original cocktail was a solution of lots of non-volatile components (sugar, Splenda, citric acid from the lemon juice, and many many other things...) in some rather more volatile solvents (ethanol and water). Only a limited amount of any of the non-volatile compounds can dissolve in a given volume of solution. So as the volatile compounds evaporated, your solution gradually became saturated, then a little super-saturated, and then finally the non-volatile components started to crystallise out in the patterns you show.In general slow evaporation of a solvent is quite a common method of crystal growth, e. g. , for X-ray diffraction studies.— — — — — —OK, its the last day of mankind, and you can have one mixed drink/cocktail, what would it be?Tequilini Ingredients: 2 1/2 oz Casa Noble Tequila Crystal Few Drops of Dry Vermouth 1/2 oz Fresh Lime Juice Mixing instructions: Shake ingredients in mixing glass with ice, then strain into a cocktail glass.— — — — — —how do you make a frozen bikini cocktail?well firstly buy a bikini freeze it and then add it to a cocktail glass and add required bverages which i dont know what they are— — — — — —Drink Recipe?'?????????There are a lot of them, any of these sound right?

Automotive Backup Camera Systems, Backup Hub
rsync can be somewhat painful if you have a very large number of files - especially if your rsync version is lower than 3. On the other hand: if you use tar, you would generate a very big resulting tar-file (unless the data may be compressed a lot). Personally, I would look at rdiff-backup, but make sure that you test your restore situation: rdiff-backup can be very memory demanding when restoring.1. Backup files being created in KubuntuIt seems you forgot to ask the question :) I will assume the question is "how do I disable creation of backup files in Kate"The answer is: go to Settings - Configure Kate - Editor Component - Open/Save - Advanced and untick "Backup on Save" for Local Files and Remote Files. Then click OK2. Ubuntu 10.10 full backupThe problem is not just re-installing Ubuntu it is also all the peripheral programs that I have on my HD. Some take much effort and time to reinstall, setting up configuration files etc. WE really do need a one-button HD back up.. I would like to do this onto a USB HD ..can it be so hard, Apple have it!!..? ron..Themotorman3. GPO backup failsYou may have to troubleshoot a little further. Are you able to backup other GPOs? Did you try using an alternative admin account? Can you create a test one and back that up? If you can, then I would check permission on the previous GPO where you are receiving the error. There is a powershell command you can use:Backup-Gpo -Name MYGPO -Path C:GpoBackup -Comment "Backup-08-21-14".4. rsync --backup-dir not getting changed data - instead it is going to the original backup locationI suppose the options -b --backup-dir do not act as you hope. You can try to use a different option --link-dest instead. Your command line should be similar to the following What is the meaning? You are telling to rsync to compare the files in /scripts/source/ (the new ones) with the ones in /scripts/diff/ (that is empty) and in the additional directory /scripts/full/ (That is the one of your backup).Notes:5. Backup internals - What happens when a backup job is running - in terms of locking and performance overhead in SQL Server?Basically, SQL Server does a dirty copy of all pages on disk. Those pages are likely inconsistent if there is concurrent activity or if there previously way non-checkpointed activity.Then, SQL Server also copies the necessary part of the transaction log that is needed to bring the out of date pages to the latest version and make everything consistent on restore. I can not speak to the multi-threadedness of the backup operation. I expect it to be parallelized. How else could you back up a 10TB database on a 10GB/sec IO subsystem?6. amt .22 backup jam problem?Its the nature of the gun. Try this, and it will sound weird. Clean the gun, and then try to feel the feed ramp for burrs. If you can feel some, use a dremmel tool, and a mild abrasive for polishing metal, and a cloth wheel, to polish it smooth. To feel the burrs best, use your tongue. It is more sensitive than your fingers. This should resolve the problem, or at least be all that you can do. If it does not resolve the problem, you can put the gun on your desk as a real cool paper weight, as that it is truly only reliable for that. Bringing it to a gunsmith is an option, but they often will charge more to work the ramp, throat, and barrel than the gun is worth. Go buy a small Ruger SP101 in .357 if you want a back up. Good Luck.7. How to backup / partition before rooting?Those on Android 6 can try the instructions that I posted here, starting at step 5. I think this will work without root, but I have not tried. You will need 6 if you are running stock because some of these commands require tools only included in Toybox. See also Ryan Conrad's great answer, based on this xda-developers guide, also linked by Firelord above8. Ramifications of Deleting Transaction Log BackupSo order of operation:If this is correct then you will be fine. As long as the LSN or chain of (backup) events since the last full backup is not broken you should have no issues with recovery
Blockchain Technology Explained: Powering Bitcoin
Blockchain Technology Explained: Powering BitcoinMicrosoft recently became the latest big name to officially associate with Bitcoin, the decentralized virtual currency. However, the Redmond company did not go all out, and will only support bitcoin payments on certain content platforms, making up a tiny fraction of its business.What is The Big Deal With Bitcoin?Like most good stories, the bitcoin saga begins with a creation myth. The open-source cryptocurrency protocol was published in 2009 by Satoshi Nakamoto, an anonymous developer (or group of bitcoin developers) hiding behind this alias. The true identity of Satoshi Nakamoto has not been revealed yet, although the concept traces its roots back to the cypher-punk movement; and there's no shortage of speculative theories across the web regarding Satoshi's identity.Bitcoin spent the next few years languishing, viewed as nothing more than another internet curiosity reserved for geeks and crypto-enthusiasts. Bitcoin eventually gained traction within several crowds. The different groups had little to nothing in common — ranging from the gathering fans, to black hat hackers, anarchists, libertarians, and darknet drug dealers; and eventually became accepted by legitimate entrepreneurs and major brands like Dell, Microsoft, and Newegg.While it is usually described as a "cryptocurrency," "digital currency," or "virtual currency" with no intrinsic value, Bitcoin is a little more than that. Bitcoin is a technology, and therein lies its potential value.This is why we wo not waste much time on the basics — the bitcoin protocol, proof-of-work, the economics of bitcoin "mining," or the way the bitcoin network functions. Plenty of resources are available online, and implementing support for bitcoin payments is easily within the realm of the smallest app developer, let alone heavyweights like Microsoft. Looking Beyond The Hype — Into The BlockchainSo what is blockchain? Bitcoin blockchain is the technology backbone of the network and provides a tamper-proof data structure, providing a shared public ledger open to all. The mathematics involved are impressive, and the use of specialized hardware to construct this vast chain of cryptographic data renders it practically impossible to replicate.All confirmed transactions are embedded in the bitcoin blockchain. Use of SHA-256 cryptography ensures the integrity of the blockchain applications — all transactions must be signed using a private key or seed, which prevents third parties from tampering with it. Transactions are confirmed by the network within 10 minutes or so and this process is handled by bitcoin miners. Mining is used to confirm transactions through a shared consensus system, and usually requires several independent confirmations for the transaction to go through. This process guarantees random distribution and makes tampering very difficult.While it is theoretically possible to compromise or hijack the network through a so-called 51% attack the sheer size of the network and resources needed to pull off such an attack make it practically infeasible. Unlike many bitcoin-based businesses, the blockchain network has proven very resilient. This is the result of a number of factors, mainly including a large investment in the bitcoin mining industry.Blockchain technology works, plainly and simply, even in its bitcoin incarnation. A cryptographic blockchain could be used to digitally sign sensitive information, and decentralize trust; along with being used to develop smart contracts and escrow services, tokenization, authentication, and much more. Blockchain technology has countless potential applications, but that's the problem — the potential has yet to be realized. Accepting bitcoin payments for Xbox in-game content or a notebook battery does not even come close.So what about that potential? Is anyone taking blockchain technology seriously?Originally published at DreamiFly.— — — — — —Please explain me what is blockchain and how is it useful?Blockchain Technology is an upcoming term mostly heard in relation to the cryptocurrencies. This record-keeping tech is very important for bitcoins. In addition to this one can also see the use of Blockchain technology in sectors like banking and investing. It also enables a community of users to control the revision and any necessary updates for the record of information. On this level Blockchain technology seems quite similar to Wikipedia. In Wikipedia, a number of users contribute to a single content. But the main difference between the 2 is in their digital backbone. Wikipedia has a highly protected centralized database. The total control over this centralized database lies with the owner. The owner manages all updates, accesses and also protecting against any cyber threats. On the other hand, for the distributed database of the Blockchain technology, every node in the network has to come to the same conclusion while each updating the record independently. Thereafter only the most popular record is held at the official record instead of the existing master copy.
