What Are FAT32, ExFAT and NTFS?
What Are FAT32, ExFAT and NTFS?
USB flash disk, I believe everyone here has used it, but did you notice the following problem when formatting USB flash disk? When formatting the USB flash disk, we usually have a choice of file system, usually two to three, namely FAT32, exFAT and NTFS. What is the difference between these three choices?What are FAT32, exFAT and NTFS?FAT32FAT32 means that the file allocation table adopts the disk file management mode of 32-bit binary number record management. Because the core of fat file system is the file allocation table, it is named from this.NTFSNTFS, fully known as new technology file system, is the new technology file system. It is the file system of Windows NT (such as Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, windows 8.1 and windows 10). The new technology file system is a restricted level special file system of Windows NT.exFATExFAT, also known as fat64 (extended file allocation table), is a file system suitable for flash memory introduced by Microsoft in Windows Embedded 5.0 or above (Windows CE 5.0, 6.0, windows mobile5, 6, 6.1). ExFAT was mainly launched to solve the problem that FAT32 does not support 4G and larger files.How to choose between FAT32, exFAT and NTFS?FAT32FAT32 format U disk, because of its relatively good compatibility, can deal with almost all operating systems. However, the disadvantage is that permissions cannot be set and the security level is low. And the most fatal is that FAT32 can only support single file transmission below 4G. With the increasing size of files, FAT32 obviously can not meet the needs of modern data storage and transmission.NTFSIn NTFS format, compared with FAT32, we can set the permissions of USB flash disk, and the maximum supported files are 256tb. Compared with FAT32, NTFS also adopts smaller clusters to manage disk space more efficiently. The waste of disk space is avoided to the greatest extent. In addition, NTFS has many functions that FAT32 does not have, such as compressed partition, file index, data protection and recovery, encrypted access, etc. In terms of interchangeability and practicability, NTFS is much higher than fat3.However, NTFS also has its disadvantages. NTFS partition adopts a "log" file system, which needs to record the detailed read and write operations of the disk, which will cause a great burden on the flash storage medium such as USB flash disk. For example, if you access a file or directory, the number of reads and writes on NTFS will be more than FAT32. In theory, the USB flash disk in NTFS format is easier to be damaged. Moreover, due to the limited bandwidth of USB flash disk, NTFS frequently reads and writes to occupy the channel, which will reduce the disk performance.exFATExFAT can also be said to be fat64. It can also be seen from the ID that exFAT and FAT32 are upgrade relationships. We also mentioned the birth of exFAT above, mainly to solve the problem that FAT32 cannot store a single file higher than 4G. ExFAT supports up to 16eb files. In addition, exFAT does not have the disadvantage of NTFS reading and writing. It is more applicable in flash memory, and can be used in Windows system and Mac OS system. It has excellent cross platform ability. It is also a file system specially designed by Microsoft for flash memory devices.The above is about the differences between USB flash disk file systems FAT32, exFAT and NTFS. After understanding them, are the students more calm when using USB flash disk? Although the knowledge has been obtained, the hardware can't lag behind!Toshiba u301 classic Falcon series USB flash diskEfficient transmission and qualityUSB3.0 high-speed interface is adoptedGreatly increase the transmission speedGreatly improve reading and writing efficiencyToshiba u301 classic Falcon series USB flash diskHigh quality original granules are usedProfessional and reliable data storageToshiba u301 classic Falcon series USB flash diskCompatible with USB 3.0 interface devices such as computersAt the same time, it is downward compatible with USB2.0 interface equipmentMultiple devices, arbitrary storageToshiba's personal retail products were launched in April 2020 with a new image of armored manToshiba's storage enterprise products have been renamed Kaixia from October 2019 and officially put into operation.

What Is Facebook Machine Learning? What Can It Be Used For?
What Is Facebook Machine Learning? What Can It Be Used For?
What is Facebook machine learning? What can it be used for?1、 What is Facebook machine learning?Facebook's machine learning feature can help you achieve the best performance in your advertising series. Facebook platform can help you get as many conversion opportunities as possible at a lower cost by determining the best performing forum, budget allocation and bidding of advertising Series in real time.2、 How does machine learning work?It will combine the data and signals from our platform and the customer information you provide to analyze and predict which people will take the desired actions. The more data available, the more we "teach" the model, so as to continuously improve the accuracy of prediction. The more accurate the prediction, the more likely you are to achieve better results. In order to help you reach or acquire customers at a lower cost, our delivery system needs to be flexible to place advertisements in all sections and manage your budget allocation in the best way. When setting up an advertising series, it is recommended to enable advertising series budget optimization and select the lowest cost bidding option. At the same time, automatic sections are used to place advertisements in all sections.3、 What is the operation mode of machine learning?There are three operation modes of Facebook machine learning: advertising series budget optimization, minimum cost bidding strategy and automatic forum.1. Advertising series budget optimizationAdvertising series budget Optimization: set an overall budget for the advertising series, and let the system allocate the budget to the best performing advertising groups in real time, so as to optimize the budget allocation of each advertising group. Advertising series budget optimization is a way to optimize budget allocation at the advertising series level. This means that Facebook will constantly automatically find the best opportunity to achieve results in the advertising series' and allocate the budget in real time to achieve these results.a. Improve performance:Get more results with the same budget. Univision, a Spanish language cable television company in the United States, reduced the installation cost of word applications by up to 33% by using the budget optimization function of advertising series rather than manually adjusting the budget at the advertising group level, and saved an average of 30 minutes.b. Easy to use, time saving:Reduce manual tracking and management of budgets, resulting in less time spent on budget planning, setup, and optimization.c. Improved delivery:If each advertising group contains overlapping audiences, our system will delete the overlapping audiences when placing advertisements. However, if the advertising series budget optimization switch button is on, in case of overlap, the budget will be transferred to a more competitive advertising group with better opportunities, so as to reduce the situation of insufficient delivery.2. Minimum pricing strategyLowest cost bidding strategy: spend the lowest single bidding amount to achieve your desired advertising series goal and maximize the value of advertising series. The lowest cost bidding strategy allows our system to set bidding for you. The goal is to obtain the lowest cost single optimization event for you. In this case, the lowest cost bidding is used:a. When you are not sure how much bidding is appropriate;b. When you want to spend all your budget.Note: when combining the lowest cost bidding and advertising series budget optimization, all advertising groups must optimize for the same event!3. Automatic versionAutomatic Forum: put advertising content in the forum that is most likely to bring advertising results. It is complicated to manually decide which sections to use for which advertisement at which time, which will waste time and money. The automatic placement function enables our advertising system to help you complete complex work, determine the best performing placement in real time, and dynamically allocate more budgets for these opportunities. Get the opportunity to cover more audiences in multiple sections of Facebook's applications and services. Achieve up to 7% coverage growth compared to Facebook only. Get customers at a lower cost and improve your return on investment. The cost of single effect decreased by 71%.4、 How to make full use of advertising series budget optimization and automatic edition? (for reference)1. Optimize advertising according to actual business results;2. If it is decided to use the lowest cost bidding option, all advertising groups should optimize for the same goal or event;3. Easily and automatically convert non-9:16 dynamic message ideas into ideas suitable for vertical or fast shooting environment. The background color of snapshot can be simply edited to flexibly control creativity;4. By selecting automatic sections at the advertising group level, first widely locate the audience and enable all sections.
Inspired by Ants, the Swiss Research Team Developed a Small Robot
Inspired by Ants, the Swiss Research Team Developed a Small Robot
According to foreign media reports, a research team at the Federal Institute of Technology (EPFL) in Lausanne has developed a small robot inspired by ants. They have good mobility and can communicate with each other, assign roles and complete complex tasks together.Due to the small size of ants, the ability of individuals is very limited. However, under the collective cooperation, a group of ants can work in an orderly way. They can find food, build complex nests, escape predators and so on.EPFL researchers' research published in the journal Nature shows that their newly developed robot has the same ability as ants. These robots are simple in design and weigh only 10 grams, but each robot has a variety of motion modes and can move in a variety of terrain.This kind of robot is named tribots by researchers. It is folded and assembled by multiple thin and light materials. Due to its strange shape, it is also called "three legged robot". And this kind of manufacturing material is completely autonomous and unrestricted. It is also equipped with infrared and proximity sensors for detection and communication. More sensors can also be configured according to the actual application.At the same time, the ingenious combination makes tribots have five different motion forms: vertical jump, horizontal jump, over obstacles, and traveling on platforms and non flat planes."In practical applications, such as emergency search tasks, these robots can act collectively. Moreover, because they have good mobility and communication ability, they can quickly locate targets in large space without relying on GPS or image feedback," the researchers explained"At the same time, because they can be manufactured and deployed in large quantities, even some" casualties "will not affect the success of the task. With its unique collective intelligence, our micro robots can better adapt to the unknown environment. Therefore, in some tasks, they will be better than larger and more powerful robots."
10 Reasons the Netherlands Is a Great Destination for Startups
10 Reasons the Netherlands Is a Great Destination for Startups
Is Silicon Canals the next Silicon Valley?The Netherlands is famous for a great many things: bicycles, equal rights, electronic music, cheese, windmills, pancakes, rain, Heineken, weed (I could go on). Its a great place to be, but few know that the country doubles as a popular hub for startups. There are numerous accelerators, incubators, and co-working spaces all providing a welcoming environment to international businesses and citizens alike.In my 15 years of traveling the world as an expat, Ive returned to the Netherlands at least six times. Allow me to share with you what makes this country a competitive destination for global businesses, entrepreneurs, and skilled workers.Why Is the Netherlands So Attractive for Businesses and Startups?The Netherlands consistently ranks high on many global indices from the fastest internet speeds to quality of life, safety, and overall happiness. Its a pleasant place to live regardless, but there are a few factors that specifically attract international tech startups and companies. These have helped it earn the rank of 1 in the European Union for its startup business climate.Diverse, Global PopulationThe Netherlands is an open, progressive society with a diverse workforce, supporting creativity and innovation. One in five in Dutch society has a parent who was born abroad. The city of Amsterdam celebrates and recognizes residents of 180 different nationalities and counting.English-Speaking90% of Dutch residents speak English, and many are multilingual.Netherlands Startup VisaThe government created the Netherlands Startup Visa for non-EU/EEA citizens who want to start a business in the Netherlands. It gives budding entrepreneurs one year to launch their business idea with an option to extend for another year. The Ambitious Entrepreneurship Action Plan also supports startups.Skilled Migrant VisaThis fast-track immigration process for highly-skilled, non-EU immigrants is of benefit to workers and employers alike.Startup Delta MissionFounded by former politician Neelie Kroes, the Startup Delta aims to merge the Dutch startup ecosystem into one single connected hub, remove barriers, and improve access to talent, capital, networks, knowledge, and markets.What does this mean in laymans terms? They want to pave the way for startups in the Netherlands. According to my research at some of the over 60 co-working spaces throughout Amsterdam, Startup Delta initiatives are directly responsible for supporting and growing the startup culture throughout the country.Tax IncentivesBesides providing a level of clarity and certainty that companies can rely on long-term, the Dutch government also offers competitive tax deductions, reimbursements, and allowances. Perks include an effective corporate tax rate as low as 5% for R&D and innovation.Infrastructure & ConnectivityAnyone who has engaged in international business knows that the low labor and operating costs in developing countries frequently come with trade-offs especially when it comes to a reliable infrastructure. Conversely, the Netherlands is known for its excellent transportation and telecommunications network, which makes doing business that much faster and easier. The country boasts some of the highest broadband speeds in Europe and is even the birthplace of Bluetooth and WiFi.Strong EconomyThe Netherlands is in the top 5 of the most competitive economies in the world, which speaks for itself.Stable Political SituationThe Netherlands is a functional, democratic, law-abiding society, which tends to create a secure climate for business operations. The Dutch are known to strive for consensus on important issues and have robust social services for their citizens, fostering added security.Optimal LocationLocated between Germany, Belgium, and the North Sea, the Netherlands is ideal for reaching any part of Europe and the globe. The Port of Rotterdam is also the largest in the world.The Netherlands has an Internet penetration rate of 95.5%. The country ranks in the top of the European Digital Startup scale over all the indicators required from a policy standpoint for improving and developing ecosystems for entrepreneurs. Coworker.comHow Many Startups are There in Holland?The Angel.co website currently lists a $3.6M average valuation and $66k average salary, with 3,325 companies, 3,098 investors, and 818 jobs available.Netherlands StartupsBrowse 3,325 Netherlands startups, 3,098 Netherlands angel investors, and 818 startup jobs in Netherlands.angel.coFor comparison, France shows a $3.3M average valuation, $60k average salary, 5,826 companies, 3,149 investors, and 1,428 jobs.What About Funding?Because the Netherlands is such a small country, access to sufficient funding has historically been a hurdle. Since options are somewhat limited, crowd-funding or going to individual investors are two primary ways of raising capital. Although this can be detrimental to a startup economy, there are now plenty of ways for entrepreneurs and indie makers worldwide to raise seed capital in 2018 and beyond. Overall, Holland is still a great place for small companies to launch before relocating to hubs such as London for the next step in their growth model.Notably, the Netherlands is also attractive to companies on the other end of the spectrum, such as Google, Uber, and Amazon. Brexit has further enhanced the countrys appeal to companies of all scales looking to relocate from the UK.What Does it Mean for You?Paris and London still receive the majority of VC funding in Europe, but the Netherlands business-friendly tax policies, English-speaking population, startup initiatives, and high quality of life are compelling for companies, entrepreneurs, and digital nomads looking for a home.Emerging economies like China and India are already in-the-know, with hundreds of companies recently setting up shop in Holland.The Netherlands has a number of strengths, including its central geographic location, excellent infrastructure and strong workforce. The personnel are very competitive within a Western European context. Roel Spee, IBM Business ServicesInterested in moving yourself or your operations to the Netherlands?

Auto Switching 12 Volt Battery Under Load
Auto Switching 12 Volt Battery Under Load
There might be better ways to do this but we need more details on the topic.However one possible way around this is Voltage sensor high current Mosfet switch. Feel free to use a micro-controller of your choice. Make sure it has adc capabilities(almost all have). You job will be simple if it has as many adc pins as the number of batteries you are planning to switch between. If that's not possible, you can always use multiplexers to do the job.Voltage sensing: Make a voltage divider to bring the charged battery voltage within range that can be measured by your micro-controller (5V, 3.3V or whatever your adc pin allows). Make sure your adc pin never sees a value which is out of range. For ex - If battery has a max voltage of 15V and my adc can accept max voltage of 5V, I can use this circuit:simulate this circuit Schematic created using CircuitLabThis will allow you to sense the battery voltages. You will know which batteries are ready for getting fed into the inverter.For switching, you need a high current mosfet - one for each battery. Parametric search on digikey will give you some results. If your max current can be 200A, better to select a value higher than that - probably 2-3 times.Another solution (cheaper) is electromechanical relay but at that current, arcing might kill it very often.If you are using mosfets, you will have heating issues so you will definitely need to attach massive heatsinks to your mosfets. Having a common heatsink for your mosfets might help because only one mosfet will remain ON at any particular time. Due to the big size, cooling will be more effective as compared to a small detached one. Assume a power dissipation of 150-200 watts in your mosfet while carrying 200A. If that's a concern, you probably shouldn't go this wayI have a 120 V / 60 Hz 2000 watt inverter which can draw up to 200 amps from a 12 V DC battery source. An AC oil heater drawing 6 amps max 15 amps is running from the inverter constantly. I want to automatically change batteries without interrupting the current to the inverter.The scenario is: several batteries are supplying the inverter. When a battery becomes depleted it is replaced with a charged battery. The invertor cannot go off line so a battery must be on line at all times. The depleted battery is switched to a charging circuit until it is fully charged then it is available to be switched to the inverter load. The battery being charged must be isolated from the inverter during charging.Having many batteries is not an issue. Having many battery chargers is not an issue.Currently this is a manual process and I'd like it to be automatic. I'm looking for: the best way to detect the depleted battery, swap the battery from the inveter to the charge circuit, detect the fully charged state then return the battery to the load circuit.This application is an off grid.

Stalls like this are often ignition-related and happen when the engine loses spark. The underlying cause is often a bad crankshaft position sensor, or sometimes a failing ignition coil (if the engine has only one coil). When this happens, open the hood and check for spark. This can be done by pulling off a plug wire (if the engine has plug wires), and placing the end near the block while a helper cranks the engine. DO NOT hold the wire as it may shock you if the ignition system is working. If you do not see a spark or hear the plug wire snapping when the engine is cranking, the fault is in the ignition system. Another possibility is a bad PCM (engine computer) relay. The power supply to the PCM is often routed through one or two main power relays. The PCM shuts down and turns off the ignition and fuel injectors, causing the engine to stall. One way to see if this is a possibility is to switch or replace the PCM power relay(s). If the problem goes away, the cause was a bad relay. If it continues, the fault is something else (possible a wiring fault in the PCM relay or PCM power circuit). Yet another possibility is low system voltage, loss of voltage, or overcharging. The PCM and other control modules require a steady 12 volts to operate correctly. If the supply voltage suddenly drops below 9 volts, or surges about 16 volts, or cuts out, the PCM may temporarily kill the injectors or ignition circuit. The underlying cause may be an intermittent short somewhere in the electrical system or charging system that causes a momentary drop or surge in voltage. These can be very difficult to find, and often require hooking up a scan tool that can capture snapshot data when the stall occurs. By looking at the data, a technician can see the chain of events that caused the stall, and hopefully identify, isolate and repair the fault. Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean. The computer should respond by adding more fuel. If the engine has a speed-density type of fuel injection system (no airflow sensor), the computer uses inputs from the throttle position sensor, manifold absolute pressure sensor, air temperature sensor and engine rpm to estimate airflow and how much fuel the engine needs. NOTE: Speed-density systems are much less sensitive to vacuum leaks than EFI systems that use an airflow sensor. If the engine has an airflow sensor (vane airflow or mass airflow), it looks primarily at the airflow signal from the airflow sensor, but also takes into account what the throttle position sensor and MAP sensor (if equipped) are telling it. NOTE: Airflow EFI systems are very sensitive to vacuum leaks, and air leaks downstream of the airflow sensor. Consequently, if the inputs from any of these sensors is inaccurate or missing, the engine computer may not add enough fuel, allowing the fuel mixture to go lean causing a misfire that produces a hesitation or stumble when accelerating or opening the throttle. The amount of fuel added by the computer when the throttle opens may also be insufficient if the fuel injectors are dirty or fuel pressure is low. The oxygen sensors in the exhaust monitor the air/fuel mixture so the computer can adjust fuel trim as needed to maintain the proper air/fuel ratio. Fuel trim adjustments can compensate for dirty injectors and/or low fuel pressure to a certain extent, but occur too slowly to offset a throttle hesitation problem. Possible Causes of Engine Hesitation or Stumble: Dirty fuel injectors (cleaning the injectors often fixes this). Bad MAP (manifold absolute pressure) sensor Bad TPS (throttle position) sensor Bad or dirty MAF (mass airflow) sensor Low fuel pressure (leaky fuel pressure regulator or weak fuel pump) Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
