What can I learn in 10 minutes that will be useful for the rest of my life?
Importance of Mathematics and variable change. I would like to share a scene from movie 21 (28) which concludes the importance of Statistics and variable change (Mathematics) in place of emotions while taking a decision. Without getting into the depth of movie lets try to grasp something which would make our decision making process more efficient. Scene A professor asks a question from student (Ben). italic Professor Suppose you are on a game show in which you have 3 door infront of you. The game host ask you to pick a door inside which there is a brand new car. Which door will you choose? Ben reply I would choose the first one. Professor Ok. Ben choosed door number 1. Now the game host opens door number 3 which is empty. Now you have a choice to change your choice of picking door once again. What would you like to do? Whether you stick to your decision or change? Ben reply I would switch my choice to door number 2. Professor How do you know he is not playing with your mind. Why would you switch the door! The game host knows where the car is. He can use reverse phycology on you. Ben reply I doesn't matter. My answer is based on statistics and variable change. Professor Please elaborate! Ben reply Initially when I was given a choice to choose door among 3 my chances of winning was 33.3%. After he opened the third door (which was empty) and offer me choice its 66.7% if I choose to switch. So yes! I would choose door number 2 and thankyou was that extra 33.3%. Professor Exactly! If you are confused to choose a decision always go for statistics and variable change. Most people don't switch their choice in fear emotions paranoia but Ben set aside his emoticon and let simple Mathematics to win a brand new car. horizontal-rule Actually we can apply this statistics and variable change concept in our daliy life; taking right decision in Interviews by setting aside our emotions and focus on simple Mathematics to take the right decision. Hope this might help! Pic source Screenshot from youtube. italic Edit Many are confused inment section so lets try to understand it in more simple way. By choosing a door you create two groups group A (your door) group B (the other door). The probability of car being in A is 33.3% (1) and probability of car being in B is 66.7% (2). This is for obvious reasons that host will open the wrong door on first place to make you decide (decision making). ( Initially when you choosed the door your probability of winning was 33.3%(1) andbined probability of other two door was 66.7% (1333.3%). italic Now after revealing third door which is empty you are down to two doors but they are still the same group A and B with same probability. When the host shows the door and it is empty that door probability shifts to the 2nd door (as initially they were havingbined probability) which is 66.7% (2). italic You should then pick group B as it has 66.7% (2) probability of hiding car. Lets take another example Suppose you are made to choose Ace of Spade from a deck of card. You randomly choosed one card. Your probability for winning bes (1). Now the host reveals each and every card and at last left with just one card which he places on table at side of your card. As the host knowingly eliminated the wrong card therefore the last card must have a probability of (51) of winning. Therefore you have a very high probability of winning in case you switch to his card. Hope this will help!
How was the PDF format created?
I was there for the whole thing. It was the 9's and Adobe was doing well. In addition to the Systems department which handled the Postscript business there was an Applications group which had Photoshop and Illustrator. John Warnock had the idea that every document that was ever printed or ever would be printed could be represented in a document. This was not an unreasonable idea since Postscript was designed for this purpose and Adobe also had some code from Illustrator that would handle the fonts and graphics and code from Photoshop to display s - this would be the second file format for the project. However there were requirements that were not being met. Requirements like forward and backwardspatibility streaming large documents through a printer driver where the printer driver has no idea how many pages there will be and opening a 1 page document and being able to jump directly to the 5th page without reading the whole file. Peter Hibberd had written a demo of an 'object oriented file format' so Richard Cohn and Alan Wootton went to work trying to adapt his work for use on the Carousel project. After many weeks of struggle it was decided that adapting his work was going to be more work than writing new code and that some of the 'object oriented' concepts were not applicable since it was finally bing obvious that a key-value format was going to be part of the solution. This was the third file format. Bob Wulff the manager of the project told Richard and Alan to 'go away' and to note back until there was a file format! The next Monday Richard and Alan started meeting at Richard's house in Menlo Park instead of going to work in Mountain View (where Google is now). By the end of Thursday Richard and Alan had described data structures and concepts for a file format on many pieces of paper. Alan went home pulled 4 overnights in a row and came back to Adobe on Monday with the fourth file format written and working in the current code. This file format became known as PDF.
How do I open a corrupt Word Docx file that refuses to open?
Thankfully these days the number of Word files bing corrupt may be diminishing and the DOCX format is tailor made to allow for easier file repair. (Note many of the s below have been blurred standing in for the recovered data because I don't want topromise the trust of the people who have sent me files.) A big thanks to Rohn7 s for some extensive editing advice. Here's what you can do to recover from Word document corruption with advice (in written and video form) and s to software service and sites that will help you do it. BEFORE YOU DO ANYTHING ELSE MAKE COPIES OF YOUR CORRUPT FILE AND ONLY WORK ON THE COPIES. SOME OF THE METHODS DESCRIBED BELOW ARE DESTRUCTIVE TO THE CONTENT OF YOUR DOCUMENTS!!! Note DOCX files are in reality conventionally zipped collections of mostly XML subfiles. You can see this by changing the extension of the file from .docx to .zip in the files properties (the quickest way is just to add .zip to the docx) by right clicking on the file and choosing to rename or by hitting the F2 key and doing the same thing. DOC files an earlier format areplicated collections of objects too but are mostly not store as zipped elements. In fact in DOC documents often the is stored in plan mode which you can see from open a copy italic of your corrupt file in Notepad or by changing the extension of the file from DOC to TXT and opening it in Word . Notepad destroys the binary structure of DOC files so only look at it this way on a copy! File corruption can occur for a number of reasons including software crashes CPU mistakesputer overheating power outages viruses partial hdd and ssd disk failures (I know that's redundant terminology) other kind of drive failures including unsafe removing of usb and other connected connected memory cards and finally these days unfortunately a lot of usb memory and memory cards are fake in that they tell theputer they are one size say 128GB which is a size you supposedly bought it at but in reality the memory stick or card only holds 8GB . When it reaches its limit it begins overwriting and corrupting the oldest files or simply throws away the data yielding in the latter case only a partial file. You can test for this with the software described here All about 'Fake' SD cards and USB Flash drives - RMPrepUSB s .

They definitely were not in my recycle bin. Don do first auto run. The interface provides lots of Filter criteria such as date created range last saved range last printed range title num pages editing time revision number file author.

Some these procedure will possibly destroy or make your file worse -(. 2 Start Word in Safe Mode by holding down the CTL key as you click to start Word . View and save the file if it opens without error. 2 Start Word without loading macros by holding down the Shift key while starting Word. This can also be done by pasting in s in the run app CMD app or the Search Cortana field of Windows. Afterwords try loading your document and see if it loads without corruption. If it does then you need to try to disable any macros you have in your template that start when Word starts and then re-enable them one at a time until you find the one that is causing the issue. 2 Change the template that you are using by renaming either the global template ( ) if you using that or find the one you are using and rename that one. 2 Start Word without it loading add-ins or the normal template by starting it from amand line the run app or the Cortana field and using themand . If your file opens normally without corruption then there is an Add-in causing the trouble. Go to File then Options and then Add-ins . In the panel windows that opens look for which kind of Add-ins are active and then go to the bottom and choose to manage those s of Add-ins. Uncheck the running Add-ins one by one or all at once if you think you don't need them and try reopening your file. 2 Change the print driver by adding another printer like another instance of the Microsoft XPS Document Writer printing from that verifying it worked deleting the original printer reinstalling it and then trying the first printer again. 2 Force Word to repair the file by starting an open dialog window in Word selecting your file in the Explorer tree and choosing Open and Repair by clicking on the tiny arrow to the right of the word Open on the open button and choosing themand from the drop down menu. 2 Change the file format using File menu choosing Save As and select a different format DOC RTF ODT etc. Then open the new file name and use Save As to return to DOCX format. 2 Formatting and corruption is stored in section breaks end of row marks for tables and the last paragraph mark of a document because it contains a hidden section break. To bypass these sources of corruption find where the document begins to corrupt and then switch to Draft view and try deleting the previous section mark or the following one. If you don't know where the corruption is try removing all the section breaks and continuing with the advice below about copying the without the last paragraph mark. If you have no section breaks in your document you can turn on the formatting marks and then copying everything but the last paragraph mark to a new document. Start on the last character before the last paragraph mark and hit Ctl-Shift and Home keys on your keyboard to select all the before the last paragraph mark. Hit Ctl-C on your keyboard to copy all the and then paste it into a new blank document (you can get that by hitting Ctl-N ). 2 If you is not appearing after a certain point in your document note the page number then switch to Web or Draft view. Just after where the truncation appears delete the next paragraph table or object (maybe even an equation) in the new view. Switch now to Print Layout view and see if the truncation of the document below the presumably bad element has gone away. If it has not continue to switch to Draft or Web view and delete more further paragraphs or objects. 2 Rohn7's and Microsoft's s advice is to group offending elements togethor. Per Roh7's reply to a post of mine If you can open a file and you have a lot of objects of one kind that you suspect are causing corruption you can group them togethor to possible stop future corruption from occurring. Grouping objects by first turning on the Selection pane. This can be found in the Home tab of the ribbon. The editing group of the Home tab has a dropdown button named Select. Click the Select button and then click Selection Pane ...Press the Ctrl button on your keyboard and then click each box (or other object?) in the selection pane. Click the Group button under the Format tab. This will group all the objects together.

Why should I own an iPhone and not an Android?
As for me theyre worth buying reasons are as follows They synchronise excellently with my Mac my playlist podcast subscriptions RSS news feeds documentsics clipboard everything is perfectly synchronised between my Mac and iPhone. GarageBand on iPhone is a nifty tool to make music on the go if you couple it with iRg then you can use it to take input from your musical instruments. If you install VizzyWig camera app on iPhone SE 6S 6S Plus 7 7 Plus 8 8 Plus or X then you can record 5K videos at 3 FPS something no Android device can do. iOS is the only device other than Windows 1 Mobile to have a full fledged PDF editor on an Android you can only sign annotate and highlight PDFs even in the best Android PDF editors you can just fill up PDF forms. On iOS however if you install Wondershare PDFelements you can not only sign annotate highlight PDF and fill PDF forms but also add or remove pages edit or delete in PDF reposition s etc. It like a full fledged Adobe Acrobat PDF Editor in your pocket. Android has no alternative to this app. iOS uses extremely low latency Mach kernel this makes them ideal to use as a MIDI controller without worrying about sound latency. Many games like The Tales of Monkey Island series The Day Of the Tentactle Remastered Sam & Max series are exclusive to iOS. The UI design of iOS apps is more organised I just hate the unorganised UI design of Android apps all UI elements of Android apps are just scattered all around. iPhones are the only phones which still offer you an option to buy small phones with powerful hardware and fast performance (iPhone SE) I just don like to carry the huge Android phones unfortunately all Android manufacturers just hell bent on increasing the size of their phones. Each app on iOS Appstore is thoroughly reviewed by Apple to check for the presence of malicious code this ensures that apps with malicious code don enter the Appstore. Google on other hand follows apletely stupid strategy wherein the readily publish a app and only remove it after they get multiples of presence of malware in it this makes Android more susceptible to malware. All Android device can be easily rooted (Except the new Android devices by BlackBerry which employ automatic root-kit detection and removal systembined with secure boot) of course rooting gives some users more control but remember if you can root it so can a hacker via a remote root-kit by disguising a remote root-kit as an app. And once a remote root-kit gets installed on your device it grants root access to all malware. iOS devices contain no bloatware most Android devices are full of either bloatware or with apps with redundant functionality. Games that use Unreal graphics engine run better on iOS devices due to the usage of Metal graphics API the OpenGL module used on Android isn good for Unreal graphics engine so games utilising Unreal graphics engine like the Infinity Blade series ain available for Android devices (except Nvidia Shield which uses Vulkan graphics API). iOS devices receive timely updates and security patches while most Android devices (except Google Pixel Nexus and Nvidia Shield) are often abandoned by their manufacturers. iPhones work good straight out of the box you don need to tinker too much to make them work good on the other hand Android devices need setup and tinkering with settings to make them work good. Apple has the best after-sales service and tech-support their tech-support team is extremely helpful and can ge even non-technical users. On other hand the service and tech-support of Android devices is often hit snd miss Sharp is as prompt as Apple but they rarely sell their phones outside Japan; Samsung LG and oddly enough ZTE have good after-sales service but horrible tech support; Sony Lenovo-Motorola have good tech-support but not so good after-sales service; the after-sales service as well as tech-support of Xiaomi & Huawei is downright pathetic; OnePlus lacks good after-sales service and a oveplicated tech-support which is not suitable for normal users; ASUS on other hand has good tech-support their after-sales service is prompt but their service stations literally try to scam you off by overcharging for everything; Alcatel is least concerned about providing after-sales service and tech-support in India they are mostly concerned about appeasing the American and European consumers; Nvidia has excellent after-sales and tech-support but damn their devices are pricey as hell and you can even make calls on those but yeah theyre great for gaming. So for me buying an iPhone is a way better choice than buying an Android device.
