LED Lighting Will Completely Solve the Price Problem to Popularize the Application
LED Lighting Will Completely Solve the Price Problem to Popularize the Application
LED lighting, which has been promoted for many years, has been used in places requiring 24-hour lighting such as medical treatment and hotels, as well as areas requiring long-time lighting such as street lamps due to its high cost. Other areas have not been able to enter on a large scale due to price reasons. However, this year and next may be a turning point."The price of LED lighting decreased very fast in 2012, which makes LED lighting rapidly enter various application fields." Wang Yongbin, marketing director of lighting products in Greater China of NXP semiconductor (NXP), analyzed this magazine on the occasion of the 2012 Hong Kong autumn lighting exhibition, "In addition, we found a new trend, that is, non dimming LED lighting products are very popular among Asians, including developed countries such as Japan and South Korea, which may be related to their use habits. Europeans and Americans prefer dimming lighting." This is good news for the LED industry, because at present, the price of non dimming IC is about half cheaper than that of dimmable IC, and IC is still the most important part of the cost of the whole LED lamps. Wang Yongbin then added: "another trend we found is that after continuing the LED ball gun and tube series, LED lamps will begin to become the mainstream demand in the next year." Therefore, in the next year, NXP and other LED semiconductor solution providers will focus on the non dimming and high-power lamp market, because the growth potential in Asia is huge.In addition to the above trends, Wang Yongbin also revealed that at present, lighting manufacturers have high requirements for power factors, because many countries, including China, especially require the FP of some lighting to be greater than 0.9, and will subsidize up to standard products. "For example, in the bidding of China's energy-saving and people-friendly projects, two points will be added for products with FP greater than 0.9, and the Chinese government will give supplementary posts. In addition, it is also required in the European energy star that when the power is greater than 25W, the FP must be greater than 0.9." He pointed out that in the schemes of some IC manufacturers, the realization of high-power factors needs to be controlled from the outside, which will increase the cost, while NXP can be realized from within the chip, which is not only convenient for design, but also reduces the cost. "For example, the ssl2109a controller can realize FP greater than 0.9, less peripherals and simple and convenient design due to the use of special circuits." he cited an example.It is also aimed at another product series ssl21081 (a) / 83 (a) of non dimming integrated high-voltage MOSFET, with high integration, less peripheral components, only 14 required, and lower overall cost. Due to the integration of MOSFET, the efficiency can reach more than 95%. However, at present, the FP of this scheme can only be greater than 0.7. "Ssl21081 (a) / 83 (a) It can achieve 5% current precision control and 95% efficiency output, complete protection functions and built-in flexible and reliable features, ensuring the lowest system component cost. It is welcomed by users in Asia and will be the main product this year and next. " He explained that not all IC companies can integrate the high-voltage MOSFET into the controller. NXP can achieve good heat dissipation due to the high-voltage SOI insulation process, so as to integrate the high-voltage MOSFET to achieve efficient lighting. For some companies that integrate 750V MOSFET, while NXP only integrates 600V MOSFET, Wang Yongbin explained that at present and in the near future, integrating 600vmosfet is enough and more The result is waste and increased costs.For the high-power LED lamp market that will become the mainstream in the next year, NXP launched ssl4120 in Hong Kong this time, which is an integrated success rate factor correction (PFC) GreenChip? Half bridge resonant controller can support high-power LED applications up to 400W. At present, it has been mass produced and samples will be available soon. Ssl420 fully supports commercial power applications and supports efficient start-up directly from the rectified general commercial power voltage range of 90 to 305 volts. In addition, it also supports low total harmonic distortion (THD) of less than 10% and high power factor of higher than 0.97 (PF) and 380 kHz typical PFC frequencies meet and exceed the traditional requirements of high-power LED lighting applications. Ssl4120 can be widely used in high-power LED applications, such as office lighting, shopping mall lighting, high and low shed lighting, parking lot lighting, square lighting and street lighting.For the confrontation between single-stage and two-stage LED driver architectures in the current market, Wang Yongbin said that NXP is the defender of single-stage architecture. The main reasons are as follows: first, NXP has long-term accumulation and advantages in single-stage; second, single-stage controller can integrate high-voltage MOSFET; third, single-stage is easy to use and easy to design, and customers can develop successfully in only two weeks; fourth, single-stage is successful at present This advantage, two-level BOM is about 10-15% more expensive than single-level BOM.Finally, when it comes to the trend of some lamp manufacturers to do vertical integration, R & D and drive IC / components, Wang Yongbin believes that this is only a temporary phenomenon and will not become the mainstream. "It is still difficult for companies making lamps to do the electronic part. In the future, they will still specialize in the division of labor, and the driving part will be independent." he personally believes.

Is There a Really Big Difference Between a Smartphone and High-end Feature Phones?
is there a really big difference between a smartphone and high-end feature phones?errrrr. the Kin Two is not a feature phone, it was a strange kind of cloud computing smartphone. so they made to be sort of the same as the iPhone in features. They pulled the plug on it. killing most of its features making it little more than a feature phone. A smartphone is a high-end mobile phone built on a mobile computing platform, with more advanced computing ability and connectivity than a contemporary feature phone. A feature phone is a mobile phone which at the time of manufacture is not a considered to be a smartphone, but nevertheless has additional functions over and above standard mobile services. It addresses the market for customers who do not want the features of smart phones, and also typically allows a lower price point.— — — — — —What Phone Should I Get and How Can I Get It?ask her about virgin mobile 35 a month for a smartphone— — — — — —Jolla (smartphone)The Jolla smartphone is a smartphone produced by Jolla that runs the Sailfish OS, released on 27 November 2013 and manufactured in China.— — — — — —What diet plan can i use during the summer that is free?If you have a smartphone, try out "Lose It" app. It is free and tracks food and excersize for you— — — — — —Should an 11 year old have a phone?If you love to waste money, if you like indulging your eight-year-old with expensive electronics so that he can impress his friends (and so that they can nag their parents for smart phones) and be distracted from what he should be doing, and/or if you want your eight-year-old to have unfettered access to the Internet, you should buy a smartphone for him.

Nokia has implemented USB OTG in many of their Symbian cellphones such as Nokia N8, C6-01, C7, Oro, E6, E7, X7, 603, 700, 701 and 808 Pureview. Some high-end Android phones produced by HTC, and Sony under Xperia series also have it. Samsung Android version 3.1 or newer supports USB OTG, but not on all devices. Host-powered: Sony Ericsson Xperia pro Needs external USB-power: Motorola Droid 4Specifications listed on technology web sites (such as GSMArena, PDAdb.net, PhoneScoop, and others) can help determine compatibility. Using GSMArena as an example, one would locate the page for a given device, and examine the verbiage under Specifications Comms USB. If "USB Host" is shown, the device should be capable of supporting OTG-type external USB accessories. In many of the above implementations, the host device has only a micro-B receptacle rather than a micro-AB receptacle. Although non-standard, micro-B to micro-A receptacle adapters are widely available and used in place of the mandated micro-AB receptacle on these devices.— — — — — —Foldable smartphoneFoldable smartphones (also known as Foldable phones or simply Foldables) are a family of smartphone form factors utilizing hinged flexible displays. Devices whose displays fold on a vertical axis are designed to fold out into a wider, tablet-like form, but are still usable in a smaller, folded state; the display may either wrap around to the back of the device when folded (as with the Royole Flexpai and Huawei Mate X), or use a booklet-like design where the larger, folded screen is located on the interior, and a screen on its "cover" allows the user to interact with the device without opening it (such as the Samsung Galaxy Fold). Horizontally-folding smartphones have also been produced, typically using a clamshell form factor. Precursors to the concept have used multiple touchscreen panels on a hinge in a similar manner, but the term is currently synonymous with implementations that utilize a flexible display; concepts of such devices date back as early as Nokia's "Morph" concept (2008), and a concept presented by Samsung Electronics in 2013 (as part of a larger set of concepts utilizing flexible OLED displays), while the first commercially available folding smartphones with OLED displays began to emerge in November 2018. The first generation of commercially-released foldable smartphones have been faced with concerns over their durability, as well as their high prices.
Do You Think That Google Ads Sometimes Waste Your Money?
Do You Think That Google Ads Sometimes Waste Your Money?
There can always be a 95% chance you are wasting your money on Google Ads and setting yourself up for a negative ROI...if you set up your ads incorrectly.It's relatively easy to create a Google Ads account and get your ads running. However, if you want to see sales coming to your bank account, there's more to it than just writing a good ad copy and targeting relevant keywords. There's a direct correlation between your Google Ads click-through rate (CTR), higher Quality Score, better ad position, lower cost-per-click (CPC), and minimum bid. The higher your CTR, the higher your ad relevance, and no one appreciates relevance more than Google.When trying to increase your Google Ads click-through rate, you should focus not only on the number of clicks but the specific actions you want every "clicker" to take. Here are some of the most important steps you should take to improve your Google Ads results:Set Up and Track Your GoalsIncrease Page SpeedEnsure Your Website is SecureEnhance Your Landing Page Quality & AppealMake Sure Your Site Has Trust SignalsIf you're curious about how you can save yourself from wasting money on Google Ads, feel free to check out this blog post Top 5 Ways to Improve Your Google Ads Click-Through Rate | Zima MediaDo you think that Google Ads sometimes waste your money?1. I have site for students like chegg but can I make money with google ads?Yes, this is a good idea. Get yourself an Adsense account, and you can have google put ads on your site. How much you can make just depends on how much traffic your site gets. and spells out all their rules. Do not try to cheat. You WILL get caught, you wo not be able to get ads for your site, and you will have thrown away an awesome opportunity to make money2. How can I run Google ads without any payment and approval?No, Legally, It's not possible to run google ads without payment. Also, Ads approval is required to actually show your ads to the ad network.But some people do run ads without budget. Here I would like to make it clear that this method is not recommended and harms the website domain in future by barring google ads advertising.The method(Not Recommended): Some people buy old Google ads account(with some threshold amount limit). let's support USD 500, Now with this google allows the advertiser to run ads for USD 500 and the pay it when it reaches this limit. This way they run ads for USD 500 for free and never pay the amount.But few of them know that google never allows the same domain(website) to run in more than 1 account if old account has some dues, or violated some policies.So, there is a way to run free but doesn't seem to be legal and good for genuine advertisers/businesses. Happy Advertising!!How can I run Google ads without any payment and approval?3. Why is Google committed to using Dart for Google Ads?The answer to this question makes more sense when you consider the alternative: JavaScript. I have dabbled in both and I am primarily a Java coder so I have some insights into this:Google Ads current system is based on GWT. Many front-end engineers in Ads are used to writing Java-like code. Switching from Java -> Dart is conceptually much easier than Java -> JS.Dart has a lot of nice properties that is hard to do in JS such as Classes, Futures, Streams. ES6 simplifies some of these for JS.Dart is optionally typed; again a feature very useful for Java developers to get accustomed to Dart. Google owns Dart: Ads can dictate how the language and the VM evolves. Something they can not do with JS.There's a couple of decent proposed solutions for running Dart based apps on mobile: Dart on Mobile | Dart. This is something you can not do with JS (all existing JS mobile frameworks like Ionic runs on a Cordova like setup, essentially a webview/browser). The result is hoped to be Dart apps approaching the performance of native apps.Why is Google committed to using Dart for Google Ads?4. Have you used used Google ads before?They make things significantly uglier and do not provide any significant income unless you have a *lot* of traffic
Linux Backup Utility for Incremental Backups
Linux Backup Utility for Incremental Backups
And why are you not considering git itself? The strategy you describe, after one full and two incremental backups, has it's complications when you continue. It is easy to make mistakes, and it can get very inefficient, depending on the changes. There would have to be a kind of rotation, ie from time to time you make a new full backup - and then do you want to keep the old one or not?Given a working dir "testdir" containing some project (files, and subdirs), git makes by default a hidden . git subdir for the data. That would be for the local, additional version control features. For backup, you can archive/copy it away to a medium or clone it via network. The revision control you get (without asking for) is a side effect of git's differential storage. You can leave out all the forking/branching and so on. This means you have one branch called "master". Before you can commit (actually write to the git archive/repo), you have to configure a minimal user for the config file. Then you should first learn and test in a subdir (maybe tmpfs). Git is just as tricky as tar, sometimes.Anyway, as a comment says: backing up is easy, hard part is the restoring.Disadvantages of git would be just the small overhead/overkill. Advantages are: git tracks content and file names. It only saves what is necessary, based on a diff (for text files at least).I have 3 files in a dir. After git init, git add . and git commit I have a 260K .git dir.Then I cp -r .git /tmp/abpic.git (a good place to save a backup:). I rm the 154K jpg, and also change one text file. I also rm -r . git. Before restoring the files I can get the precise differences:Here I want to follow the git restore hint.After git --git-dir=/tmp/abpic.git/ restore *:The jpeg is back, and text file btext has not been updated (keeps timestamp). The modifications in atext are overwritten. To reunite the repo and the (working) dir you can just copy it back. The files in the current dir are identical to the .git archive (after the restore). New changes will be displayed and can be added and committed, without any planning. You only have to store it to another medium, for backup purposes. After a file is modified, you can use status or diff:And just like git knows about "more" in file 'btext', it will also only store that line incrementally. After git add . (or git add btext) the status command switches from red to green and the commit gives you the info. And you can really get at the contents, somehow:And then the first 4 hex hash digits To travel back in time by one commit it is:btext's blob has a different hash before the last commit, the others have the same.An overview would be: Instead of manually timestamped tar files you have commits with a message and date (and an author). Logically attached to these commits are the file lists and contents. Simple git is 20% more complicated than tar, but you get decisive 50% more functionality from it. I wanted to make OP's third change: change a file plus two new 'picture' files. I did, but now I have:So what did that Your Name Guy do exactly, in his two commits, shortly before 6 pm?The last commit's details are:And to check the second-to-last commit, whose message announces two pictures:This happened because I tried git commit -a to shortcut git add . , and the two files were new (untracked). It showed in red with git status, but as I say git is not less tricky than tar, or unix."Your debutante just knows what you need, but I know what you want" (or the other way round. Point is it's not always the same)1. How to fix Time Machine's "This backup is too large for the backup disk”?This happened to me recently; I was pretty annoyed because I expected that if there was not enough space, Time Machine should just delete the oldest backup.The problem turned out to be that the disk contained only one (large) backup, and did not have room to store the current delta (delta = changes to files since last backup).I realized this when I looked at the disk contents and saw that there was only one backup folder under Backups.backupdb. I used Disk Inventory X to look at the contents of my hard disk, and identified a few large folders which did not need to be backed up. I excluded these from the backup using "Time Machine" > "Options" > "Exclude these items from backups". The info from Disk Inventory X also led me to delete a bunch of large unused files.After the two changes listed above, the backup proceeded successfully. I did not have to launch the backup, it automatically retried. I presume that my changes brought the delta to a small enough size that it fit in the remaining free space on the backup disk.UPDATE: This happened to me again recently, and just excluding folders from the backup was not enough, so I found another trick. Let's say you analyze your hard disk contents and realize there's a 20GB folder (let's call it UselessStuff) which was being backed up. You exclude it from the backup as described above, but that does not delete the previous backups of UselessStuff from the disk, and you still do not have enough space for the backup to complete. Since you do not need any backups of UselessStuff, you can enter Time Machine, right click on UselessStuff, and click "Delete all backups...". In my case, this freed up enough space to let the backup continue successfully.2. Backup large files in an external diskAddonics manufactures a range of HDD duplicators that duplicates hard disks very fast without any connected computers. From naked disks, their solutions also support USB-to-USB copy, etc. Do check it out.We have one in the office, limited application, but it is the most frictionless way to duplicate large files (in fact, the whole disk) to another.3. MSSQL Backup QuestionThere are two ways people backup databases. One is to do dump of the database (i am not a dba so i am not sure the mechanics of doing the dump) to a text file, then write that file to tape. The second is to use an agent that is aware of the RDBMS that you are using. Both of these methods will get you everything you need to restore the DB to a working condition. You can use backup exec, but you will need to make sure that the MSSQL Agent is installed on those systems. Since you have more that 250 server's i am guessing you have at least one dba on staff - I would ask them as to how backups of the SQL servers are currently being done. They should know some of the basics at least enough to get you started. They would know things like whether your predecessor used an agent, or backed up text dumps
