(Functional) OOP with Message Passing

There is a great misunderstanding of what object-oriented programming really is and its origins. The term "object" was first coined in the 1950s and became really popular on the early 60s on Lisp circles as a powerful design pattern. Finally on the 70s the first object-oriented language, Smalltalk, was developed by Alan Kay.

The truth is that what object-oriented programming really represents has been lost over the years as modern languages kept copying the syntax and ideas imposed by the C programming language. Alan Kay has declared publicly many times that the essence of OOP is the concept of message passing, and that modern programming languages focus more on the object notation itself than in the concept of message passing. This of course is the motivation for this article and our focus here will be to show the essence of object-oriented programming using a popular modern programming language, JavaScript. I hope you enjoy this journey.

What is a message?Before going deeply into object-oriented implementation it is fundamental to go deeply into the prerequisites. Let's start with messages!So what the hell is a message? When you want to communicate two endpoints you need a standardized information to be passed along the way. A message is this standardized information and is essential to guarantee that the two endpoints will be as decoupled as possible. It is important to notice that if the producer sends a message that the consumer does not understand, nothing happens because it is not a predefined standard.Our problemSuppose I want to grab a student's best grade from a list of grades in all the exams he participated. We could write a silly function to do that without complex functionality, just vanilla JavaScript for the masses:The above code works perfectly, but since we are working with an array as a parameter, it does not sound very semantic. It is not clear that the list of grades belongs to a single student. How do we fix this? Well There are two solutions to this problem:We change the name of the function to getStudentBestGradeWe pass as a parameter the student as an object.Of course, we will focus on the second one! yay!Using the "class" keywordWell, since we are object-oriented programming lovers, we can do it with the class keyword. This is such an easy job anyway:Now the code looks much better as I can simply pass on the student as a parameter and: Bingo! Much better than the previous versionBut this is not the idea behind this article. It looks quite nice but we are using JavaScript object-oriented notation to do that. Why not do it with functions only? So keep on reading :)Our First Functional ObjectTo understand fully what we will be talking about in the next paragraphs, we need to start simple. We will first use the concept of function scope to create a functional counter with a private embedded value.Holy cow, that is a function that returns another function. Don't be scared, this is quite a normal thing to do. I know it may sound absurd for many people, but that is actually very useful. I like to tell people that this first function is a function builder because it lets you create more dynamic functions by simply injecting state into them.Ok, but what the heck is state? Think of state as anything that can cause your functions to output different values for the same input, in this case, the parameter initial does exactly that.

As we can see in the example above, for the same counters, every time we call the function we have as output a different value. So just as a review, note that the Counter function builds in the example two functions with private embedded value inside. Isn't that what private attributes on objects do? ;)Now that we understand state injection, we can complicate things a bit more and write a JavaScript-only class using functions only. Why JavaScript only? Because we will use JSON (JavaScript Object Notation).As we can see, we used the same approach as on the counters example. Our function student (that represents our class) receives the grades as a parameter and maintains it as a private attribute _grades. The public methods (getGrades, getBestGrade) of this class are returned as a JSON. Since this class is written using a fancy looking function, there is no need to use the new keyword.This implementation is very common on old JavaScript source codes but is very powerful. But as I promised before, we want to do it the right OOP way, and that means that we need to use the concept of message passing. The message passing implementation is language agnostic and should work on any decent programming language out there.I hope you love this, now is when the real fun begins! Message Passing Object NotationLet's write the same object as before but using the message passing strategy.

As we can see, this OOP implementation at first sight does not look very elegant in JavaScript, but I can guarantee it will work on most popular programming languages. The idea is not what this implementation can do differently, but how we can extend this and implement real cool hierarchy and polymorphism (We will do this after the next title).To use the message passing strategy, you have to understand that for each message, the object will have different handlers (functions) that will be specialized in dealing with the message. If we pass no parameters, then we can simply get the function and use it in a more flexible way. Below I show you how you can use the message passing strategy:An advantage of using this object and not the previously declared object, the one using JSON, is the fact that in case we send an invalid message there will be a predefined response for this request that we can model for our domain.Inheritance and PolymorphismFor this example, we need a class to extend from, and there is no other class that looks nicer than Person (I was not very creative really). Since every student is a person, this means that every student should have all attributes and methods from the base class. Below I have implemented the class Person.Since Student needs to extend the base class, we should do some nice things to make it all work out together and produce a nice looking hierarchy:Students must have a name and an age. So for now on, the constructor should also have name and ageOne of the attributes of our class will be the base class that will be constructed with the parameters sent on the Student constructorIf the message we are looking for is not found, we will redirect it to the base class on the default case of the switch.Here we go, ladies and gentlemen! :DFinally, we have a nice little class that extends Person using functions and message passing only. You can use it the same way as before, by sending messages.

ConclusionI hope you liked what you read. This article focus on the main idea behind object-oriented notation and how to use message passing. Of course this is a very humble implementation and most languages optimize a lot how classes are represented when they become bits and bytes. There are lots of other things we could implement such as method overload and multiple inheritances, but they are quite an easy task to do once we have these things implemented.

·RELATED QUESTION

Do decimal equivalents to binary number values hold significance in software programming?

No, there is no meaningful relationship between the decimal and binary notations of the numbers. One is base 10 and the other base 2 and ten is not a power of two. The reason we use base-10 Arabic numerals is probably because have ten fingers and because it's a much better system then Roman numerals. Nobody was thinking about binary digits at the time.However, there is a relationship to hexadecimal numbers, which are base 16. 16 is 2^4 so each digit represents four bits (binary digits). This makes going from hexadecimal to binary and vise versa a snap. For instance, if you know that the hex number A (10 decimal) is 1010, then you know right away how to decode the hex number AAAA: 1010101010101010When you're working with binary numbers and boolean operators hex is a lot more intuitive.150 OR 64 in decimal is very awkward. I can't do that in my head. But 96h OR 40h is no problem. You only have to think about a single nibble. You know that 9d is 1001 and 4 is 0100 so you know you can add 4 and 9 to get the result: 13d, or Dh. So the answer is D6. The translation from D6 into decimal (13 * 16 6214) however is awkward, so it's nice if you can avoid using decimal

No Code: How to Build Apps and Automate Processes with No Programming Knowledge
The future in which everybody can code will probably never happen. And being practical, even if we had a basic knowledge of some of these almost ubiquitous languages, like Python or JavaScript, it wouldnt be enough to start building an app or a website from scratch. In the best case, youd be able to make a nice pet project, closer to a university practice than something to build a business on or sustain your companys workflow.In the software development industry, there is a growing demand for no-code and low-code tools. Without writing a single line of code, they help to start something quite right. Not needing to know how to code to create applications is a fascinating idea.Many companies are already using this in their internal applications or creating automated processes that they could not otherwise afford, because they dont have enough working capital (developers and UX designers) or because they are still proof of concept in the purest bootstrapping way.SaaS Platforms for Prototyping, Building and Automating in the Cloud Without Writing a Line of CodeThis kind of SaaS platform is visual interfaces that use components already created, connected, and easily reusable. They allow us to build flows based on user actions, or certain previously-described rules.Generally, the path you follow is to create a prototype, test, and finally distribute it to the end-users (deploy). Later on, we will be able to think about whether to migrate that experiment to something within our technology stack involving the developers. In the meantime, we can continue to use these third parties as if it were our system.We can find various platforms within the business of many companies, such as a Typeform to create a perfectly segmented, vitaminized form, which we then export to a Google spreadsheet, AirTable, or even analyze in some machine-learning process in the cloud.On the other hand, automation has made its way strongly using Zapier or IFTTT, so that when any trigger (event) happens, it performs certain actions such as sending an email through Mailchimp or Twilio, saving a multimedia file, updating some charts in a dashboard with Google Spreadsheet, etc.The examples mentioned previously are SaaS platforms that allow for various actions or processes that, until now, would require a service infrastructure that is difficult to configure and not at all affordable for a small company. The business model of these platforms is focused on providing more and more customized services without the need to integrate a single line of code. Only by offering dozens of integrations to other services that serve as a source of data or a communication channel to the end-user.We all know that most websites and applications are hosted in the cloud, either on Google Cloud, AWS, or Microsoft Azure, for example. However, we also have to keep in mind that all these associated processes come from other SaaS services. All the emails, SMS, or Push Notifications we receive as users come from Mailchimp, Salesforce, Twilio, Amazon SNS, etc.Even the actions that triggered the sending of those communications have not required, in most cases, a couple of lines of code or complex event queues. Many of them come from services such as Firebase o AWS, for example, which are capable of generating audiences based on the associated analytical tools. Although, if we need something concrete, we can include small scripts or code fragments in the cloud as Cloud Functions or Lambdas.What Is the Difference Between Non-Code and Low-Code Tools?It is crucial to make a clear differentiation that no-code and low-code are not the same. In the case of low-code platforms, we need a minimum of programming knowledge. On the other hand, in no-code, we work with visual interfaces, and we are not going to see (unless we want something advanced) a line of code.Low-code is a huge boost for lower-skilled programmers and even a great way to launch something fast for more advanced programmers who can work on it later, creating integrations with more challenging code. Its also a natural progression in the domain of software development where languages are becoming more abstract by adding layers and layers to focus more on what we want to do than on how.In no-code, we focus on the question of what we want the user to see. Thus, abstractly, the tools can create, according to our indications, the multi-platform visual interfaces of our idea, whether it is a web app, native, or even an exchange of messages by slack or by one of the voice assistants.The low-code concept is not something we havent seen before, but rather its from the 1990s. Thats how they described it recently in an article in Spectrum IEEE. We can remember those CASE tools and that old Microsoft Visual Basic framework that many people will still remember. Right now, some tools try to emulate this approach, such as Microsoft Power Apps, Oracle Visual Builder, or Salesforce Lightning Platform. Even Google has recently acquired AppSheet, a no-code platform for creating mobile apps.One of the web development tools that is having a big influence is Webflow, which is capable of creating complex websites with just a couple of lines. You can design the look and feel of your website by simply dragging components, connecting flows, and reusing anything the platform provides without forgetting the external integrations that would be more challenging. You can see dozens of tutorials on its website.The Three Key Elements of a No-Code PlatformIn short, this kind of Non-Code platform has to have the following elements to allow such user empowerment without the need to write a single line of code.A user interface builderWebflow is a good example. We can work with a set of components already defined through a visual interface that is closer to a design tool than a programming tool. It works by merely dragging and positioning it where we want the element to be shown to the user. Whether its a box with a paragraph, a few images, a formulary, or a dynamic layout that depends on an API that provides us with the data, we can combine all these elements and reuse them on each screen.Visual modelingBesides dragging and dropping elements on a layout, we have to define steps, flows, and connections between the elements. It even creates a hierarchy between the components and the data models. So most of these tools allow you to visualize and configure using diagrams of the relationship between the elements.IntegrationsIt is essential that our applications can communicate with other tools, especially those SaaS tools we mentioned at the beginning, to automate the process or communicate with the user.Where Do You Begin With These Programming Tools Without Dropping a Line of Code?The first step would be to think of some processes that we can automate. This way, we can start to get comfortable with automation tools like Zapier, IFTTT o Microsoft Flow.Creating some real flows that, for example, check the email and write a registry in a spreadsheet, or that trigger some automatic message or integrate a small CMS that processes actions depending on the state in which we place each of the elements, for example. Whether it is the products of a virtual store or on the board of pending email to customers or contacts. There are hundreds of integration from Gmail, YouTube, Spreadsheet, Drive, Dropbox, Salesforce, Stripe, social networks, or even sending SMS, pushes, or creating flexible databases such as Airtable.Recently I found the website of Codeless How, where you can see small video tutorials on how to create a set of integrations that automate many processes such as a chatbot calendar, a complete No-Code MVP, a personal assistant, etc. All are using the above tools.Afterward, I would try to explore some of the tools that allow creating a digital presence. My favorites are Webflow, AppSheet, and Microsoft Power Apps.Of course, no-code platforms dont mean that they replace software developers entirely. Rather, they are an evolution of ecosystem software tools that allow more and more people to be empowered in the software building chain. Above all, they allow you to focus on what is essential and to iterate quickly with functional prototypes to assess whether an idea is feasible before developing it by code or integrating it into our product stack·RELATED QUESTIONSoftware programming question involving Java?If you have been through the top 100 google searches, then there is not going to be much that we can suggest. I suggest you get your hands on something like Programming For Dummies. This book will guide you through things like variables and objects (neither of which are specific to Java). I would suggest Barnes and Noble and Amazon to do a search for beginning programming books. Once you have some titles, you local library can probably get them for you if they don't have them
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.

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!

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?

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.
PLEASE HELP ME CHOOSE a VIDEO CAMERA!?
PLEASE HELP ME CHOOSE A VIDEO CAMERA!?the Flip ultra HD is a really good HD portable camcorder, and it's fairly cheap. A lot of famous youtubers use it, such as timothydelaghetto. that's what i would buy, definitely.— — — — — —Online Poker with Microphones and Video Cameras888 Poker offers a few tables . but I didn t pay to much attention , because A: it is likely that they play other tables too . so you can t really know if something you think is a tell really applys to your table . and B: I think you will see a lot of Fake Tells . I didn t enjoy playing there because most players had really bad soundquality or playing music in background . so it gets really bad when you have background noises from 5 other players .— — — — — —shouldn't cops be made to wear video cameras all the time they are on duty now that we have the technology to?For the saftey of the officers that would not be a bad idea. After all that's what the cops say when they hand cuff you this is for your safety— — — — — —Which of these two video cameras is the better one?this question, or the fundamentals of it, shop damn around this communicate board as though we are meant to be conscious of your very own needs. we wo not go with a digital camera for you. you are able to study the specs and look on the gadget for your self. .. so please gain this and make a call. in my view I desire Canon dSLR cameras.— — — — — —What do I record on a video camera?Put the camera down next to the sleeping cat or dog and upload clips of what they do when the doorbell rings. Go to a thrift store and buy some old VCR tapes or ??? and then show every body how your saving and editing old family movies. Mostly by cutting up the tapes and sorting them out on the table to watch later?.— — — — — —What are the best, cheapest video cameras with a mic-in jack?I believe he said best, cheapest. The cheapest, that I would recommend would be the Canon ZR 800, ZR 900, ZR 930. They are all fairly decent camcorders. They are not very big but will get the job done and look good. Good luck!— — — — — —Can you suggest a video camera with these qualities?right here are issues to evaluate: kind: I actual have had large reviews with Sony and Canon, however it rather is confirm its a kind you have heard of. Media: MiniDV is the marketplace popular for high quality, extra effective than DVD. The tapes are very small so length is not a subject. additionally, MiniDV tapes do not smash down as speedy as DVDs, and in assessment to DVDs, there is not a alternative on the marketplace, so as that they are going to be around for a whilst. different constructive properties: seek for a 3CCD digital camera. it rather is one that has a seperate sensor for each shade so the popular is plenty extra effective. seek for one that has intense optical zoom. manufacturers will supply rather intense zoom numbers for digital zoom, yet digital zoom hurts the popular. Optical zoom is what you opt for for. as far as connecting to pc or television, any of the hot camcorders have USB, firewire, and composite video connections so transfering would desire to be a breeze.— — — — — —What video cameras are meant for shooting skateboarding?flip video cameras are good for taping skateboarding— — — — — —Best canon video camera for 200 or less?New? There are not any. You might get a left over FS 400 on Amazon for $240.00 but it's not "best"— — — — — —how much would a good video camera?extremly cheap would be 50-100 good quality 200-400— — — — — —Can cell phone "destroy" video camera? The other poster is incorrect. If you use a cell phone, it puts out radio waves. Radio energy can easily interfere with electronics in several ways. 1) it might cause interference with any unshielded electronics in the camera 2) the radio waves may induce heating of electrical components, which could damage your camera over time. 3) you may get noise on the sound portion of your video (in addition to your conversation). It wo not be enough to crash/trash your image, but you may see interference lines in the image. I can vouch for this with a digital still camera and a mobile car radio -- in Africa on safari, the guide was transmitting on the radio while I was taking a photo, and the electrical interference appeared in the still image as very fine, evenly spaced lines. Solution: keep the cell phone a reasonable distance away from the camera. Thanks to the inverse-square law, cell phone energy dissipates very quickly. Besides, talking on the cell phone will interfere with the sound anyway.
The National Key R & D Plan Launched the Key Project of "key Technologies and Demonstration of Inter
In order to implement the tasks proposed in the outline of the national medium and long term science and technology development plan (2006-2020), the national key R & D plan launched the implementation of the key special project of "key technologies and demonstration of Internet of things and smart city".
