What is the maximum number of rows in a mysql table?
If you use an int or bigint as your primary key, you can only have as many rows as the number of unique values in the data type of your primary key, but you don't have to make your primary key an integer, you could make it a CHAR(100). You could also declare the primary key over more than one column.There are other constraints on table size besides number of rows. For instance you could use an operating system that has a file size limitation. Or you could have a 300GB hard drive that can store only 300 million rows if each row is 1KB in size.The MyISAM storage engine supports 2^32 rows per table, but you can build MySQL with the --with-big-tables option to make it support up to 2^64 rows per table.The InnoDB storage engine doesn't seem to have a limit on the number of rows, but it has a limit on table size of 64 terabytes. How many rows fits into this depends on the size of each row.Read more - Maximum number of records in a MySQL database table
How do I connect a PenDrive to a mobile phone?
A simple OTG (ie. On The Go) will work. Most of the devices worked with OTG while most of them not.Use ES File Explorer I think that is much more efficient while working with the OTG. Actually working with it is so easy.images referenced from : shopclue.com
How do I claim the warranty for a SanDisk memory card?
My sandisk ultra micro SD card has been corrupted recently. Thought to buy new one. I have bought it from amazon, and have been using it since last 1 year. So, amazon was not in picture for claiming warranty. Googled for process of claiming warranty for sandisk products in India. First i read answer of Ravi Thatté, it seems troublesome. Then Hari Thambi suggested calling there toll free number, but i do not like to wait.Due to office work forgot about the card for more than 1 month. On 10th October 2017 visited Global Leader in Flash Memory Storage Solutions , and filed for ONLINE RMA Submission. As per website service is not India is not listed in Supported countries, selected “Country not supported” in country, and filled rest of the contact detail along with photographs of memory card and amazon Invoice. Within minutes of submitting form, received acknowledgement mail from sandisk, saying i will be contacted with in 2 days.Exactly after 2 days received another mail stating approval of online RMA request. I was expecting as stated by Hari Thambi, i will have to send my card to sandisk service center and then they will send me replacement card, but i was wrong.After receiving this mail, with in 1 hour, there was a call from sandisk customer care. There was no need for waiting. Lady on the other end explained procedure for getting new card, and answered all my queries regarding my old card and the best part, i was asked to collect replacement card from local sandisk service center.Luckily it was with in 1 km radius of my home. Went to Sandisk service center in the lunch break. I have to show email/SMS from sandisk for RMA reference number. Service center guy collected older card, and handed over brand new sandisk memory card in same configuration.In short, within 2 days of submitting online RMA request form got new replacement card from sandisk. All i have to do was, fill up one form and spare my 10 minutes for visit to sandisk service center. In my case Sandisk has beaten famous Amazon customer care.
I have made two mistakes in filling online application of navy UES entry form. Can it be corrected or will it straight away get rejected?
You will get a call if found above the cut off percentage/ criteria finalised by the authorities. Minor error in address I.e. no block no and locality would may cause problem in delivering SSB call letter by postman rather than to Naval authorities . Any way ,in your case first you will be facing interview in campus prior to SSB so you can correct your postal address at that stage. Previous SSB details can also be corrected then only as no correction is permitted post submission of online form.
Is there a way to fool Turnitin?
Yes, there are lots of ways.Plagiarism detection-programs work by taking a string of words and then running them through a database. Much like just copying random sentences from your text and running it through google - you would most likely get a result from the original text.So, to beat it, you can do either of these:1:Thisxisxmyxplagiarizedxsentence (change the color of the x's to white in microsoft word, so they appear as spaces for the reader) This will completely put the program off, because it will search its database for sentences that make no sense. I personally have not tried this method, but I've heard of people doing it.2:The best method by far.Converting the whole text to PDF format, then altering the corresponding "character map" - a map of the sequence of characters used in the text. Although the text would remain visually unaltered, Turnitin would not be able to make any sense out of it because the link between the text and its printed representation will be broken. It's basically the same thing as if you were to draw all the letters of your text perfectly in paint and then pasting it into Microsoft Word - it appears the same to a human reader, but the plagiarism-detector doesn't know how to "read" it as the sentences could look something like this to the program: akfgoieigidofgk dofkgodkafig idogaodfkfo oadirtodfpgYou can also convert text into a series of Bezier curves to represent the shape of letters rather than using the characters themselves. Almost the same thing.It's not really hard to do, and less risky at a high level as you can excuse yourself with it all being a technical flaw IF you were so unlucky as to be questioned about the plagiarism program not being able to detect anything. Just try to look like you know nothing about computers. 3.For people who are fluent in a secondary language.Find a good essay and translate it. Source: Made some extra money by doing people's schoolwork for them. Sometimes it called for creative solutions when I couldn't be there and they had been using me for every single non-live test the past year. Good luck, but remember that cheating your way to a high-end job isn't going to work for obvious reasons. I'm all for cheating on things that are not relevant to your desired education though.
What are some cool WhatsApp tricks?
You need a spare SIM Card for this.If you think you are addicted or wish to go off WhatsApp for sometime without deleting your account or using the 'Change number' option available on WhatsApp (because this notifies all groups that you are a member of) or uninstalling , follow the steps below -1. Go to Settings >> Applications >> WhatsApp >> Clear dataNow you are logged out of WhatsApp without uninstalling the application and nobody is notified about this. Also, you stop getting any new notification messages.2. Now sign in using your new SIM number. Insert the spare SIM card you have in another phone for sometime (to receive one time verification code).WhatsApp will first try to auto verify your number. Since that will fail, as you are signing in with a different SIM number, it will ask you to enter the verification code. Enter the code you receive on the new number (you will receive a text message or call)Once the verification and initialization is done - You have a new WhatsApp account on the same phone You have all your contacts No groups (:D) without being rude Nobody has been notified about this. You didn't have to uninstall WhatsApp. And you still have your old account with all the groups too. You still get to use your other number for everything else except WhatsAppSo you can now carefully choose whom you want to share this number with and keep your notifications limited. You can also recharge this new SIM and keep it as spare for emergencies. Most importantly - You can now switch between these two WhatsApp accounts on this device anytime you want without verification code (WhatsApp asks for it only once for a new device)This trick is particularly useful if you think you are addicted and want to limit your usage or you have exams or something important coming up. Now you can keep WhatsApp communication open to few people without being rude to others.
