• What is the difference between `git fetch origin` and `git remote update origin`?

  - by Norman Ramsey

  In response to a question about pulling one commit at a time from a git repository, I was recommended to use git remote update instead of git fetch. I have read both man pages but cannot say I understood either in its entirety. Can anyone explain to me how git fetch origin and get remote update origin behave differently?

• Creating a loading screen in HTML5

  - by espais

  I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• PostgreSQL: Why does this simple query not use the index?

  - by David

  I have a table t with a column c, which is an int and has a btree index on it. Why does the following query not utilize this index? explain select c from t group by c; The result I get is: HashAggregate (cost=1005817.55..1005817.71 rows=16 width=4) -> Seq Scan on t (cost=0.00..946059.84 rows=23903084 width=4) My understanding of indexes is limited, but I thought such queries were the purpose of indexes.

• How can i resolve the N+1 Selects problem ?

  - by Maxime ARNSTAMM

  Hello everyone, I have trouble understanding how to avoid the n+1 select in jpa or hibernate.

Could someone explain it to me, or give me a link with a clear complete explanation please ? I'm sorry if this is a noob question, but i can't find a real clear article or doc on this issue. Thanks

• Is it secure to use malloc?

  - by Felix Guerrero

  Somebody told me that allocating with malloc is not secure anymore, I'm not a C/C++ guru but I've made some stuff with malloc and C/C++. Does anyone know about what risks I'm into? Quoting him: [..] But indeed the weak point of C/C++ it is the security, and the Achilles' heel is indeed malloc and the abuse of pointers. C/C++ it is a well known insecure language. [..] There would be few apps in what I would not recommend to continue programming with C++."

• How secure is a PostgreSQL database if my server is stolen?

  - by orokusaki

  If I have a server with a database if top secret data in PostgreSQL and my password is practically impossible to crack (128 character string of all sorts of weird chars, generated by hand). The server password is also uncrackable in theory (basically, ignore the possibility of a password crack on the DB). Aside from a password crack, how easy is it to get the data out of this database? Assumptions: Only the DB exists on the server. There is no password in a PHP script or anything like that The person who has the server is a computer / DB / hard-drive recovery expert I'm not using any hard-drive encryption or anything out of the norm for protection I'm trying to understand the risks involved with somebody gaining physical access to my server's hard-drives.

• facebook graph api..get friends of friends

  - by Krishnamurthy

  I am using the FB graph api to get a list of my friends' friends using: https://graph.facebook.com/<id>/friends?access_token=<token> Now the weird thing is that this works for some of my friends and does not work for some others. Could somebody tell me why this is happening and a possible fix? In cases where it does not work, I get the following message: "Can't lookup all friends of YYYYYY. Can only lookup for the logged in user (XXXXX), or friends of the logged in user with the appropriate permission" And I repeat, I AM ABLE to get friend lists of some of my friends using the above URL. What permissions are being mentioned here?

• Extracting rightmost N bits of an integer

  - by srandpersonia

  In the yester Code Jam Qualification round http://code.google.com/codejam/contest/dashboard?c=433101#s=a&a=0 , there was a problem called Snapper Chain. From the contest analysis I came to know the problem requires bit twiddling stuff like extracting the rightmost N bits of an integer and checking if they all are 1. I saw a contestant's(Eireksten) code which performed the said operation like below: (((K&(1<<N)-1))==(1<<N)-1) I couldn't understand how this works. What is the use of -1 there in the comparison?. If somebody can explain this, it would be very much useful for us rookies. Also, Any tips on identifying this sort of problems would be much appreciated. I used a naive algorithm to solve this problem and ended up solving only the smaller data set.(It took heck of a time to compile the larger data set which is required to be submitted within 8 minutes.). Thanks in advance.

• C++ - Resources in static library question

  - by HardCoder1986

  Hello! This isn't a duplicate of http://stackoverflow.com/questions/531502/vc-resources-in-a-static-library because it didn't help :) I have a static library with TWO .rc files in it's project. When I build my project using the Debug configuration, I retrieve the following error (MSVS2008): fatal error LNK1241: resource file res_yyy.res already specified Note, that this happens only in Debug and Release library builds without any troubles. The command line for Resources page in project configuration looks the same for every build: /fo"...(Path here)/Debug/project_name.res" /fo"...(Path here)/Release/project_name.res" and I can't understand what's the trouble. Any ideas? UPDATE I don't know why this happens, but when I turn "Use Link-Time Code Generation" option on the problem goes away. Could somebody explain why does this happen? I feel like MS-compiler is doing something really strange here. Thanks.

• Visual Studio 2010 and Silverlight - Adding Data Sources

  - by Villager

  Hello, I am interested in building a Silverlight application that uses RIA Services. I am using this video (http://live.visitmix.com/MIX10/Sessions/CL08) as an example. In that video, the presenter uses the "data sources" tab to populate the view. However, I cannot figure out how to add a data source from within Visual Studio 2010. I have a database on my local machine. This database is the sample AdventureWorks database. When I select my Silverlight application, there is a UserRegistrationContext in the data sources window. However, I cannot figure out how to add a new one that connects to my AdventureWorks database. Can somebody tell me how to do this? Thank you!

• Why does Javascript's OR return a value other than true/false?

  - by Fletcher Moore

  I saw this construction in order to get the browser viewport width: function () { return window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth; } I understand the browser quirks involved. What I don't understand is why || returns the value. So I tried this alert(undefined || 0 || 3); and sure enough, it alerts 3. I find this bizarre, because I expect true or false. Could anyone explain what's going on?

• Why is git better than Subversion?

  - by Ben Mills

  I've been using Subversion for a few years and after using SourceSafe, I just love Subversion. Combined with TortoiseSVN, I can't really imagine how it could be any better. Yet there's a growing number of developers claiming that Subversion has problems and that we should be moving to the new breed of distributed version control systems, such as Git. Can anyone explain how Git improves upon Subversion?
