• How to get familiar with "what happens underneath of Java"?

  - by FidEliO

  I did not study CS nor IT. I just became a developer, now working with Java. Actually, since I now work with a big company writing high-scalable web applications, I think I need to be better with details. I have no understanding of what happens underneath of Java. Java Performance, Server-Side Java might be the buzz words?!! I am very poor with those more of low-level details but I do not know where to look honestly. I started looking for some keywords in Amazon, ended up reading books like "pragmatic programmer", "clean code", "code complete" which IMO they are not what I am looking for. Could you please give me some learning resources (books, articles, blog posts, online trainings) for this matter? I also read this post as well: Approaching Java/JVM internals But I think I need a pre-step before jumping into the OpenJDK, right?!

• App for finding icons easily?

  - by artfulrobot

  Occasionally I need to use a custom icon for something - a launcher created with alacarte, a custom .desktop file, or just a particular folder viewed in Nautilus. I know there are LOADS of cool icons installed on my system at /usr/share/icons but browsing them is really awkward. Everything is scattered around, duplicated in different sizes (or symlinked to .svg) etc. So, say I'm looking for a text file icon, or a purple folder or such, searching is a faff, and then when you do find results you need to work out what the best quality one is. Made me think that someone might have written an app for this?

• No desktop after installation of nvidia drivers

  - by hovmand

  I have a problem very similar to this guy: Desktop does not show when I installed nvidia drivers!. I have the same problem with the desktop not being present when I install choose the nvidia drivers from the software sources dialog. I've trie the answer mark as the solution, but this doesn't help me. Still get the same result / bug. I've also tried just to reconfigure it, like this guy says: http://ubuntuforums.org/showpost.php?p=12303179&postcount=4, but that didn't help me either. Then someone suggested that I should try Bumblebee. I followed the installation (https://wiki.ubuntu.com/Bumblebee#Installation) and after the reboot the resolution was still crappy, but this time the desktop did show up, but with bad graphics and I couldn't use optirun and it turned out that bumblebee couldn't start. I hope someone might know whats wrong or what I'm doing wrong. I have a Lenovo W520 with a nvidia Quadro FX 880M and I'm running ubuntu 12.10

• How to install all versions (stable/beta/unstable) of Google Chrome side by side without conflicts?

  - by sobi3ch

  I have the stable version of Google Chrome on my box. And each time I'm trying to install beta or/and unstable versions then I run into the same problem: The following packages will be REMOVED google-chrome-stable The following NEW packages will be installed google-chrome-beta 0 upgraded, 1 newly installed, 1 to remove and 0 not upgraded. Need to get 34.5 MB of archives. After this operation, 3,109 kB of additional disk space will be used. Do you want to continue [Y/n]? I need to remove the first version before installing another. I know I can't install existing packages side by side but I'm looking for solution not for answer like: "You can't do it", I already know I can not. So in summary my question is: How can I install all Google Chrome versions next to each other? (There needs to be a way..)

• what else except web development is a good choice for freelancing? [closed]

  - by Sali

  I'm looking for a technology that when I learn I can build useful things that brings money by selling what I have built. I tried web development but Ifound that there are many things that I have to learn: html, css, javascript,ajax,jquery ,etc. I need to focus on one thing and learning it from scratch and continue learning if there is any update in that technology rather than learning new things in css and javascript and the server side language. I want to focus! However, I'm not sure what is going on in the future of technology and I need to learn something for freelancing. could you tell what is the thing thatis popular and will bring me money as good as web development?

• arrays format (Javascript)

  - by João Melo

  i have a list of users, with minions, something like this: User52: minion10 minion12 User32: minion13 minion11 i've been keeping in an array where the "location" is the id, like this: Users: [52]User minions: [10]minion [12]minion [32]User minions: [13]minion [11]minion so i can access them easily like this: user[UserID].minions[MinionID] (ex: user[32].minions[11]) but when i print it or send it by json i get something like this: {,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,minion,,,,,,,,,,,,,,minion} but should i keep using like this or should i change to something like this: User = function(){ this.minions = ...; this.getMinion = function(value){ for(var m in this.minions){ if(this.minions[m].id == value){ return this.minions[m]; break; } } } } and get it like this: user.getMinion(MinionID); Question: i get better performance using a "short" array but using loops every time i need a minion, or using "long" arrays, but no need for loop and getting values directly from the id "name"?

• Sony VAIO wireless card not connecting intel 4965AGN

  - by marcski55

  I'm running a Sony VAIO VGN-CR410E, and recently moved it to Ubuntu from Windows 7. Both my home and work networks (which I maintain) run WPA/WPA2-PSK authentication for security. My wireless network card (intel 4965AGN) will not connect to them unless I am in the same room (kind of defeats the purpose of wireless). The PC is 4 years old and the routers are brand new (last month or so). Had no problems with it with Win7, but Ubuntu just doesn't like the networks. As an IT manager, my laptop needs to work, so any help is appreciated. If this is a duplicate, please let me know of what. I've spent hours searching and nothing has worked. Thanks for your help. (This is my first experience fully relying on Ubuntu). I can see the networks and attempt connection, but it fails authentication. Let me know of any code you need.

• Given two sets of DNA, what does it take to computationally "grow" that person from a fertilised egg and see what they become? [closed]

  - by Nicholas Hill

  My question is essentially entirely in the title, but let me add some points to prevent some "why on earth would you want to do that" sort of answers: This is more of a mind experiment than an attempt to implement real software. For fun. Don't worry about computational speed or the number of available memory bytes. Computers get faster and better all of the time. Imagine we have two data files: Mother.dna and Father.dna. What else would be required? (Bonus point for someone who tells me approx how many GB each file will be, and if the size of the files are exactly the same number of bytes for everyone alive on Earth!) There would ideally need to be a way to see what the egg becomes as it becomes a human adult. If you fancy, feel free to outline the design. I am initially thinking that there'd need to be some sort of volumetric voxel-based 3D environment for simulation purposes.

• In Google Analytics, how can I determine the value of a page if no goals or revenue have been determined?

  - by Brandon Durham

  I have 4 years of data in Analytics with over 20 million pageviews for the entire site. No goals have ever been set up, and while the site is an ecommerce site, no ecommerce features in Google Analytics have ever been taken advantage of. So I have no way to determine what the actual value of a page is. I've been tasked with determining if a particular page on the site is worth keeping around. How might I use all standard data (pageviews, bounce rate, time on page, time on site, etc.) to help determine the value of this page? I really appreciate any help I can get!

• Detecting pixels in a rotated Texture2D in XNA?

  - by PugWrath

  I know things similar to this have been posted, but I'm still trying to find a good solution... I'm drawing Texture2D objects on the ground in my game, and for Mouse-Over or targeting methods, I'm detecting whether or not the pixel in that Texture at the mouse position is Color.Transparent. This works perfectly when I do not rotate the texture, but I'd like to be able to rotate textures to add realism/variety. However, I either need to create a new Texture2D that is rotated at the correct angle so that I can detect its pixels, or I need to find some other method of detection... Any thoughts?

• Audio libraries for PC indie games [closed]

  - by bluescrn

  Possible Duplicate: Cross-Platform Audio API Suggestions What options are out there these days for audio playback/mixing in C++? Primarily for Windows, but portability (particularly to Mac and iOS) would be desirable. For a small indie game, potentially commercial, though - so I'm looking for something free/low-cost. My requirements are fairly basic - I don't need 3D sound, or many-channels - simple stereo is fine. Just need to be able to mix sound effects and a music stream, maybe decoding one or more compressed audio formats (.ogg/.mp3 etc), with all the basic controls over looping, pitch, volume, etc. Is OpenAL more-or-less the standard choice, or are there other good options out there?

• How do I run Microsoft Explorer 8 plus on Ubuntu?

  - by user169487

  First off, you should know I'm a Ubuntu newbie who has become passionate since my strangely low-priced Dell computer showed up with Ubuntu loaded on it and it could do almost everything I need from a computer. But now I've got a problem. I know, it's like asking how to use a cassette player on your computer, but in South Korea EVERY website is made to work with exclusively on MS Explorer PLUS Active X, which Microsoft finally killed with 9. Hence, I have to use 8, as there are some Korean sites I need to access for searching, banking, etc. So I see that the way to go is to load PlayOnLinux, but then I it tells me to delete these. Do I really have to do that? Should I just hit "Install Anyway"? Or would that be just asking for trouble?

• Safest way (i.e. HTTPS, POST, PGP) to send decryption keys through the web?

  - by theGreenCabbage

  I am in the final stages of development for my Revit plugin. This plugin is programmed in C#, and distributed via a DLL. One of the DLLs is an encrypted SQLite database (with proprietary data) that is in the form of a DLL. Currently, in development stages, the decryption key for the SQLite database is hardcoded in my main DLL (the program's DLL). For distribution, since DLLs are easily decompilable, I am in need of a new method to decrypt the DLL. My solution is to send our decryption keys from our servers securely to the host's computer. I was looking in POST, thinking it was more secure than GET, but upon research, it appears it's similarly insecure, only more "obscure" than GET. I also looked into HTTPS, but Hostgator requires extra money for HTTPS use. I am in need of some advice - are there any custom solutions I can do to implement this?

• how to recover all database when migrate to 5.5.8 from 5.5.1

  - by anirudha

  the installation process of MySQL on windows are very simple as other software you need just configure them and they works. but somebody after migrating their mysql server to 5.5.8 confuse that their old database is now gone but it’s not  you need to do something to get back go to C:\ProgramData\MySQL\MySQL Server 5.1\data the programdata folder commonly hidden in any version of windows. you find their some folder cut them all you want to recover. note that don’t copy the file mainly in data folder just like err pid or log because they are configuration file and the configuration of mysql 5.1 and 5.8 both are different after copy the folder  go to C:\ProgramData\MySQL\MySQL Server 5.5\data paste here the folder restart mysql and all database is now in your hands.

• BCM 4311 Wireless Not Working on 11.10-Tried All Forum Suggestions

  Hi I've spent hours trying all the suggestions listed on Forums on this problem all over the internet and I still can't get my wireless working. It's very discouraging because it might force me to go back to Windows which I hate. Can someone help? Perhaps I can give you some information to help identify what the issue is? b43 isn't coming up in my list of drivers...just Broadcom STA which doesn't work. I think I've removed all the blacklisted stuff... Thanks in advance! Annie

• changed plesk root name, what DNS settings get modified?

  - by NRGdallas

  we recently changed our plesk server's main URL from siteold.com to sitenew.com. many websites had their NS set to ns1.siteold.com - does plesk automatically update that to need ns1.sitenew.com? should I change the godaddy settings? attempting to change them states "Nameserver Not Registered" - is this simply the delay required? lastly, when adding a new domain to plesk, one would simply need to adjust the nameserver for that site in godaddy to ns1.sitenew.com or ns1.newdomain.com? (does plesk have a centralized name server, or does each site acquire its own?)

• What is the point in using real time?

  - by bobobobo

  I understand that using real time frame elapses (which should vary between 16-17ms on average) are provided by a lot of frameworks. GetTimeElapsedSinceLastFrame, and it gives you the wall clock time. But should we use this information in basic physics simulation? It looks to me to be a bad idea. Say there is a slight lag on the machine, for whatever reason (say a virus scanner starts up). The calculations all jump, and there is no need for this. Why not use a virtual second and ignore wall clock time? For gameplay on the level of Commander Keen, shouldn't you always use the virtual second and not real-time? (Besides stopwatch timing for race games) I don't see a need to use real time and not a fixed 16ms time step.

• SSRS optional parameters settings

  - by Natasa Gavrilovic

  Recently I had to create couple SQL Server Reports (SSRS) with optional parameters built in. It took me a while to refresh memory how this can be done. It was very simple to create reports and processes behind, but connecting these two were are little bit challenging – stored procedure was tested and worked fine, but when the report was passing optional parameters it didn’t returned expected results. After tweaking SQL stored procedures and reports parameter options, the following approach turn to be the winning one. 1) Defining report parameters: From Menu bar select ‘View’ and ‘Report Data’ Newly open window should have ‘Parameters’ folder display Right click on this folder and select ‘Add new parameter...’                             Default values need to be added from a query                 A query values need to include ‘’ (empty string) – as highlighted                   2) SQL stored procedure should have CASE statements inside WHERE and it was the only way that a report was getting correct results back.

• Display large amount of data to client through pagination

  - by ebram tharwat

  I have a web application in which i need to show a big number of data or records for clients. Now i 'll use pagination but i was wondering should I: Load all the data once then pagination, sorting and sarching 'll be easy..But it 'll takes big time(using local DB it takes up to 9 sec.) Or each time i show new page(from the pagination) i make a new request to server and then new request to DB to get the next records..But then what if the client click on Prev button, i 'll make a new request to get data that I had previously..Should i cach data that are loaded before and how if that's good technique? So load all data once or make a new request every time i need data that maybe have been loaded before. I'm using ASP.NET MVC SPA with durandaljs and knockoutjs
