• Java (or possibly other languages) learning path

  - by bgo

  I am familiar (as a self-learner) with C, python and php such that i can solve some problems involving simple steps (for example, i easily do calculations for physics lab reports with python which normally would take 4x-5x times longer with a calculator). The point here is, as doing such things, i learnt the idea / concepts of programming language and problem solving along with oop or fuctional programming etc. Recently i have started Java and, with the familiarity of other languages, i am doing well for starters but i need guidence. -I am thinking of learning syntax from sun java tutorials and then practicing with codingbat.com or similar sites. I need a reference book that i can study deeper aspects of the topics i am learning. What do you suggest about these? -The problem is (and always have been) the lack of practice. I need coding and problem-solving practices sources. I stuck at the point where i can't figure out what to do next. Can you suggest any source (possibly like codingbat)? If i could plan a learning trail, i can progress faster and efficiently. So i need ideas, comments, suggestions. Thanks in advance.

• Windows 8.1 Update 1 Disk Usage 100%

  - by Gookjin Jeong

  Background Information / Computer Specs I have a 14-inch Samsung Series 5 Ultra. Core i5 CPU, 750GB HDD, 8GB RAM, Intel HD Graphics 4000. I've had the computer for about 1.5 years with no major problems. Problem The issue appeared at the beginning of April this year, when I updated the OS to Windows 8.1 Update 1 (not from 8 to 8.1). After being on continually (except for at night, when I put it on sleep mode) for about 48 hours, the disk usage as seen by Task Manager hits 100%. When this happens, everything from opening/closing applications to typing and even bringing up the start screen by pressing the Windows key becomes extremely slow. The only way to make the disk usage decrease is to restart the computer. Then the problem repeats. I've used my current laptop (as well as my previous laptops) this way -- putting it on sleep mode at night and restarting it only when Windows needs to install updates -- for a long time. So I know the 100% disk usage is not due to the way I use the computer. The thing that causes the spike varies. Sometimes it's System, sometimes it's one of the various applications I installed (e.g. Chrome, Evernote, Spotify, Wunderlist, iTunes, etc.), and sometimes it's Antimalware Service Executable, etc. Tried Solutions I think I tried almost every solution out there for this problem: Running the check disk command (chkdsk /b /f /v /scan c:) from Admin Command Prompt Running Windows Memory Diagnostic Disabling Superfetch and Windows Search from services.msc Running "Fix problems with Windows Update" from Control Panel -- Troubleshooting Updating and rolling back the graphics driver (Intel HD 4000) Disabling "Use hardware acceleration when available" from Chrome settings Disabling Intel Rapid Storage Technology Running the SFC /SCANNOW command as recommended here Running a quick scan & a full scan from Windows Defender (no threats found) Taking the hard drive out and putting it back Refreshing the computer, from the Update and recovery -- Recovery option in Windows settings NONE of the above worked for me. I was about to give up but then noticed that one of the main culprits of the disk usage spike, as shown in the "Disk Activity" section of the Resource Monitor, was C:\System (pagefile.sys). I googled around and found that one of the recommended solutions was to disable pagefile. I then went to **Control Panel -- System and Security -- System -- Advanced system settings -- Advanced tab -- Performance settings -- Advanced tab -- "Change" under Virtual memory and discovered that the number for "Currently allocated" at the bottom was 1280MB, although the number for "Recommended" was 4533MB. I immediately changed it to 4533MB and checked my family members' computers to see what the numbers were like. All of theirs had a currently allocated space that was only slightly smaller than the recommended space. See screenshot below: This might fix the problem. I'll have to wait a couple more days.But if it doesn't, what in the world should I do next? I'm guessing the hard drive isn't failing because This computer is less than 2 years old; and Speccy says that the status of the HDD is good. Update 5/27/2014 The "4533MB" solution did not work. I had to reboot the computer about 30 minutes ago because the disk usage again hit 100%. When I opened Resource Monitor the C:\System (pagefile.sys) again was shown to be the culprit. I have now disabled pagefile entirely via the same window shown above in the screenshot. The number for "currently allocated" is now 0MB. Will update again in a couple days, or if the problem occurs again, whichever comes sooner.

• Event ID 8021 The browser was unable to retrieve a list of servers from the browser master

  - by Ash

  We have a LAN where workstations are randomly losing network connectivity for brief moments of time. The workstations can also take a long time to login to the domain. During our troubleshooting we have found an error log on a few Windows 7 workstations: Warning BROWSER 8021 The browser was unable to retrieve a list of servers from the browser master \\random-pc on the network \Device\NetBT_Tcpip_{BBABCDE9-D8A0-4399-93F2-492FE0848B12}. The data is the error code. What do these errors mean? What computers should have the Computer Browser service enabled, workstations and/or servers? The environment is a mix of Windows 7 & Windows XP workstations on a Windows Server SBS 2011 SP1 domain.

• Can't connect disk management to remote XP PC from local Win7/Server 2008

  - by Grez

  Scenario as follows: support technicians using Windows 7 PC's or Server 2008 terminal server are unable to connect Disk Management MMC snap in to a remote PC when the remote device is running Windows XP. "Disk management could not start Virtual Disk Service (VDS) on ". This can happen if the remote computer does not support VDS, or if a connection cannot be established because it was blocked by Windows Firewall." Connecting from another XP machine or 2003 server to the same XP machines works fine. Even connecting from XP/2003 to the Win7 or 2008 server works fine. Windows firewall disabled on all devices. I'm guessing this is something to do with the fact that XP uses logical disk manager service whereas Win7/2008 use Virtual disk manager service. But there doesn't seem to be any way to use logical disk manager service from 7/2008 to connect to XP...

• Synergy reports connected but mouse doesn't hop between screens

  - by tor

  I'm using synergy between two windows computers (Windows 7 32-bit, acting as the server part, and Windows XP 32-bit, as a client). I'm running the server part as admin, as suggested in some posts when running synergy in Vista/7, and I think it's properly configured in the server part: It reports on both sides that the connection has succesfully been established, but there's no way to move the mouse from one screen to the other (neither from server2client, nor client2server). Any ideas?

• Asus MyCinema U3100mini Choppy

  - by dsimcha

  I'm running an Asus MyCinema U3100mini ATSC on Windows 7 64-bit. When I play live TV in Windows Media Center, it's very choppy and uses 500+ MB of RAM, I'm guessing due to the hard drive buffering functionality. Is there any way to disable the live TV pause buffer completely? If not, can anyone recommend alternative software that: Works with the MyCinema. Is lightweight and not horribly bloated with features I'll never use like Windows Media Center is. Edits: This is a dual boot system. I've discovered that the tuner actually works fine on XP. It also works fine on my other computer, which has slower hardware and also runs Windows 7 64-bit. The problem actually seems to be with playback at large screen sizes, not with hard drive buffering. Everything works fine below a certain window size and fails for large windows or full screens. Also, the same thing seems to happen whether playing live or recorded TV. As far as the obvious stuff goes, I have the latest video drivers from ATI for my Radeon x1050.

• Installation is forbidden by system policy

  - by Frost

  Note: I'm posting this here on Superuser as I think the issue is more related to the Windows Installer than the game itself. My friend is having trouble installing Company of Heroes and CoH: Opposing fronts under Windows 7. A couple of percent into the installation, when the C/C++ runtime is being installed, the install fails with the following message: An error occured while installing the Windows Installer package "C:\Users\...\AppData\Local\Temp\...\...\vcredist.msi". Error code 10212:00000659: MsiInstallProductW returned 00000659: This installation is forbidden by system policy. Contact your system administrator. We have tried: Making sure that any previous installations have been completely removed, including searching and deleting any files/folders/registry entries matching "THQ" (the publisher) and "Relic" (the developer). Installing into a brand new user account Running Setup.exe as administrator Running Compatibility check for Setup.exe, which suggested Windows XP but failed when trying those settings out Does anyone know what might be the cause of the system policy error?

• Weird File Corruption

  - by Viet Norm

  My Windows 8 broke few days ago and I had to reinstall it (see Can't boot Windows 8). Afterwards, I found some corrupt files on C drive. Ok, it happens, but this is really weird. Corrupt files seem to contain stuff from Windows registry. For example, this is beginning of one of the corrupt files: hbin ` PÿÿÿT h i s z o n e c o n t a i n s w e b s i t e s t h a t y o u t r u s t n o t t o d a m a g e y o u r c o m p u t e r o r y o u r f i l e s ... I googled and found that 'hbin' often refers to "hive bin" of Windows registry. Then I searched the registry for the readable part of corrupt data, and found the text in some registry value (not the text above, but something I found in another corrupt file. I'm assuming the above is also from registry). My question is, how could this happen? Was it a virus, or did Windows somehow corrupt these files while attempting to repair itself?

• TCP Windows Size vs Socket Buffer Size on Windows

  - by Patrick L

  I am new to Windows networking. When people talk about TCP tuning on Windows platform, they always mention about TCP Window Size. I am wondering whether Windows uses the concept of "Socket Buffer Size"? On Windows XP, the TCP window size is fixed. We can set it using the TCPWindowSize registry value. How about Socket Buffer Size? How can we set Socket Buffer size on Windows? Can we set it to a value different from TCP window size?

• Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

  - by tednewk

  I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

  Below are my dual boot settings. Both are on different partitions, default is Windows 8. Both were working fine. There are multiple users of this machine, few run 8 while few 7. All 7's users are novice and they use Internet only. I frequently update Windows 8 but not 7. Few weeks ago, Win 7 stopped booting. Machine gets restarted while booting with 7(Windows 7 start up glowing-Win-logo-screen does not appear) and the 8's loader reappears. Win 7's partition still exists and contains Windows folder What steps should i take to check the problem?

• Using my System as the server- need advice

  - by Ashwin

  We are deploying my web application in my system in jboss. And I am planning to use my system as the server as well. There are no html pages or jsp pages deployed. The client requests for resources and the server provides the resources in the form of objects. We are also using databases(Postgresql-15 tables) as the database server(this will also reside in my machine). My system configuration is Windows Vista, 2.3 GHZ, 4GB Ram, 32 bit. There can be many requests coming in at the same time. So is this configuration enough? Should we go with a different Operating System like Windows Server? I have never used Windows Server OS. How will it be different from other windows operating systems? Or if you feel please some other OS will be good in this situation, please suggest.

• Can the Installation Monitor from the Win2K Resource kit be used on newer OS's?

  - by Scott Chamberlain

  Can the utility "Installation Monitor" from the Windows 2000 Resource Kit Tools for administrative tasks be used on newer OS's, specifically, Windows Server 2008 R2. The main thing I am concerned about is it may error will not track things correctly without letting me know that that it errored due to how Windows has changed between 2000 and today. If that is not the correct tool to use to monitor what a application is writing to the hard drive and registry, can you recommend me what I should use instead?

• How to make mouse in Windows 7 act the same as Windows XP

  - by Phenom

  In Windows XP using TweakUI I could enable an option so that when my mouse goes over an inactive window, it makes that window the active window. There is also another separate option so that if the window becomes active, it automatically becomes the topmost window. I like to enable the former but not the latter. For Windows 7 I have not been able to find the same thing. What I found instead is an option inside windows that does something similar. If I move my mouse over an inactive window, I have to hover over it for a while before it becomes active. It is not instantaneous. The second problem is that once it does become active, it automatically makes itself the topmost window, covering other things I don't want covered. In summary, this is what I want in Windows 7: When my mouse goes over an inactive window, it immediately makes it the active window. When it activates the window, it does not raise it above other windows.

• Windows 7 is shutting down unexpectedly, according to the logs.

  - by dlamblin

  Here's a message from my eventvwr EventLog (Windows Logs System): The previous system shutdown at 11:51:15 AM on ?7/?29/?2009 was unexpected. This is funny because I was wondering why the system shut down while I was playing Civilizations IV full screen. Now I know. It was unexpected. Has anyone encountered and resolved this? A little background: I am running Windows 7 RC inside VMWare Fusion 2 (just updated a few months back) on a MacBook (Bitterly not Pro) aluminum-body. Windows 7 occasionally will shut down. This isn't a quick turn-off, it's a shutdown where all the programs are exited, the system waits until they quit (and Civ4 doesn't prompt me to save), it even installed Windows Updates before restarting. And yes it is restarting right after the shutdown. Because I run a game in full screen mode I do not notice any dialog with a countdown timer or anything like that that might be a warning. As I have iStat on my dashboard widgets I can see about 8 temperature monitors. I have seen the CPU get up to 74C before, but during the shutdown, though it seemed hot to the touch (always is), it read 61C for the CPU, 60C for heatsink A, 50C for heatsink B and in the 30s-40s for the enclosure and harddrives. As I type this now, the temps are actually higher, so I don't think the temperature caused it. I have at least six such events dating first from 5/17 which was a week after installing Windows 7. I did find one information level warning from USER32 in the system log that says: The process C:\Windows\system32\svchost.exe (DLAMBLIN-WIN7) has initiated the restart of computer DLAMBLIN-WIN7 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Recovery (Planned) Reason Code: 0x80020002 Shutdown Type: restart Comment: And another 15 minutes before that from Windows Update: Restart Required: To complete the installation of the following updates, the computer will be restarted within 15 minutes: - Cumulative Security Update for Internet Explorer 8 for Windows 7 Release Candidate for x64-based Systems (KB972260) Which I think kind of explains it. Though I don't know why restarting after an update would create an error event of "shutdown was unexpected", isn't that pretty odd? Now, how do I set it to never restart after an update unless I click something. Application of solution: As fretje reminded me, there's a couple of configurable settings for this, in windows 7 they're much in the same place as in Windows 2000 SP3 and XP SP1. Running gpedit.msc pops up a window that looks like: Windows 7 has changed the order and added a couple of newer options I've italicized: Do not display 'Install Updates and Shut Down' in Shut Down Windows dialog box Do not adjust default option to 'Install Updates and Shut Down' in Shut Down Windows dialog box Enabling Windows Power Management to automatically wake up the system to install scheduled updates Configure Automatic Updates Specify intranet Microsoft update service location Automatic Updates detection frequency Allow non-administrators to receive update notifications Turn on Software Notifications Allow Automatic Updates immediate installation Turn on recommended updates via Automatic Updates No auto-restart with logged-on users for scheduled Automatic Updates Re-prompt for restart with scheduled installations. Delay Restart for scheduled installations Reschedule Automatic Updates schedule

• Which version of Java should I use for learning?

  - by Dan

  I am a QA engineer interested in mobile development and automation.I have basic programming experience (intermediate level Python, C++ programmer) and as most companies choose Java for writing frameworks I need to pickup Java. I use Ubutnu 12.04 LTS and I will be using Head First Java as learning material. When I searched for JDK options I found Oracle Java 6 and 7 and Open JDK. I read somewhere in Ubuntu forums that Java 6 is not recommended on Ubuntu systems and I am a little bit confused about which version should I use, that would be compatible with the book and the OS.

• is it better to spend my free time mastering a language I work with or learning a new one?

  - by edthethird

  I work full time on an android project and am very comfortable with both java and the android framework. On a good day, I would rate my abilities at an 8, and maybe a 7 on a bad day. I've recently found myself with more free time then I'm used too, so I have been working on a lot of personal projects. I am beginning to wonder what others think about this; is it worth my time to continue experimenting and pushing Android, or would I be better off learning another language? What do you all think about this? What would you do with more free time and energy than you know what to do with?

  To give light to the situation: I am currently one of two programmers working in a small startup software company. Part of my job requires me to learn a Web development framework that I am not currently familiar with. I get paid by the hour. So the question is: Is it wholly ethical to spend multiple hours of the day reading through documentation and tutorials and be paid for this time where I am not actively developing for our product? Or should the bulk of this learning be done at home, or otherwise off hours, to allow for more full-on development of our application during the work day?

• What's the normal way machine-learning algorithms are integrated into normal programs?

  - by Benjamin Pollack

  I'm currently taking a machine learning course for fun, and the course heavily focuses on Matlab/Octave to write the code. One thing mentioned in the course is that, while Matlab/Octave are great for prototyping, they're very rarely used for production algorithms. Instead, those algorithms are typically rewritten in C++/Python/etc., using appropriate libraries, before reaching customers. Fair enough; I get that. But here's my question: is that done for cultural reasons, for technical reasons, or because there is really no language that provides Matlab/Octave-like fluidity, but in a compiled form that can be linked from C/C++/$MainstreamLanguage? The game industry uses Lua for game logic because it's easy to embed, and vastly superior for expressing things like AI. Likewise, there are Prolog variants for rules-heavy applications, Scheme variants for compilers, and so on. If there's a matrix equivalent language, what is it? If there isn't, why is this field different?

• Java dev learning Python: what concepts do I need to wrap my head around?

  - by LRE

  I've run through a few tutorials and written some small projects. I'm right in the middle of a small project now infact. All is going well enough thanks in no small part to Uncle Google (who usually points me to Stackoverflow ;-) Several times in the last few days I've found myself wondering "what am I missing?" - I feel that I'm still thinking in Java as I write in Python. This question over at StackOverflow is full of tips about what resources to read up on for learning Python, but I still feel that I'm a Java dev with a dictionary (pun unintended) to translate into Python. What I really want to do is refactor my head to be able to write Pythonic Python instead of Java disguised as Python (not that I want to loose my Java skills). So, the crux of my question is: what concepts does a Java dev really need to learn to think Pythonic? This includes anything that needs to be un-learnt. ps: I consider language syntax to not be particularly relevant to this question.
