• Squid 2.7.6 not honoring ACL rules

  - by peppery

  Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.

• How to access network shares, printers, etc.through Windows 7 Built-In VPN?

  - by mbrion

  After I have successfully connected to a Windows 7 box via the built-in VPN: how do I access shares, shared printers, network appliances, etc.? So, call me bad at googling, but: I can find dozens of articles on "How to Set up a VPN Connection" and "How to connect to a VPN" for Windows 7... but I can't find a single article on how to access resources after connecting. I have a home VPN set up in Windows 7; I was able to connect to it from my friend's Windows 7 machine last night. I expected to be able to UNC into my shares; I also expected to be able to go to "Start Computer" and Click "Network" on the left side, and then see all of the devices on my home network (while the VPN was connected). Am I missing something obvious? How do I make this happen?

• Configure (Apple) Mail to delete email from IMAP server after specified time

  - by ttarchala

  I am using a corporate mail account which is synchronized via IMAP to both my desktop client and my iPhone, which is exactly the way I like it. However, the account has a limited quota. With POP3 access, this was not a problem, as POP3 clients could be configured to remove messages from server after specified time. This option is missing from my Apple Mail IMAP account configuration pane. Is there a way to replicate this feature with an IMAP account, either on the client, or on the server side? If not, I will probably have to move old messages manually to some local folder on my Mac. Is there a method to retain a single-click searchability of both archived and current mail folders together?

• How to learn to program [on hold]

  - by user94914

  I went to a community college and got a degree in computer science, but I found out I only learn very little about programming. As a result I landed byself a office assistant work (for a year now), I want to study on my own and apply for some internship / very entry level development job. I am wondering how should a person learn to program now? I feel that I might not doing it correctly, I understand everyone has a different approach, but I am really clueless on what to do, as it seems I am 5-10 years away. 1) Read the old college programming textbook cover to cover, learn every single concepts, do all the practice problems and master them (1-2 times until error free). Currently reading this java book 2) Work on any project, keep on googling and reading tutorials (including the books on that specific language). I have been doing 1, but the progress is really slow, about 2-5 pages / hour, over a 1000+ page book, I felt really discouraged. I have a few of them to go through (data struction, analyis algorthim, computer theory, operating system.) I wonder is this the right method to do? I know it is going to take time, but I am hoping to get some advice from current programmers.

• How can I check that I'm not frying the chipset on my 945 gclf?

  - by Journeyman Geek

  I'm running an old 945 gclf as a home server. Its an odd little system which has a passively cooled single core atom 230 processor, and a small heatsink/fan combo over the chipset. lm-sensors/sensors detects one temperature sensor which I guess is the processor. coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (crit = +100.0°C) The fan on it is making rather horrible noises and I am considering unplugging it or using a speed reducer. There's also a risk it may fail anyway. Is there any way I can monitor the temperatures of the chipset or be warned of any issues with it? Is there anything specific I can watch out for that would indicate trouble?

• Live HTML Preview

  - by netbeanstips

  When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

• Does Microsoft offer a corporate IM/collaboration tool similar to Campfire? My googlefu skills appear to be failing me today.

  - by user54266

  I mentioned to my boss that we should look into a single unified IM client that we could use and secure on a corporate level, and then suggested Campfire. We're a primarily Microsoft house so he suggested we use something that would better integrate with SharePoint and the other tools our end users use in house. However, I'm not aware of any Microsoft tool that does something like this. Obviously there is MSN Messenger but I think/hope he wasn't referring to that. Other than a product from 2005 I haven't been able to locate a Microsoft corporate IM tool...does anybody know what he may have been talking about?

• Should I never put a transactional replication distributor on a subscriber server?

  - by Stuart Branham

  What factors into choosing a distribution server for transactional replication? In our topology, we've always had the distributor reside on the publishing server. We rarely generate snapshots and performance is good enough, so this is okay for us today. One of our instances is moving to a cluster, so we need to move the distributor off for resilience/symmetry. Right now our two choices are to use a server physically close to the publishers, or our single subscription server. Our publisher is in our main office, and our subscriber is in a colocation facility off-site which our ISP runs. We have a pretty good line to it. The reason we're even considering the latter is to save work and licensing costs.

• Precise exposition of an image for set number of frames (Vsync?)

  - by Istrebitel

  I need to make a simple enough program in C#, but it seems to be impossible via usual WinForms means. I need to show something (a string of text, an image) on the screen for very small time interval. Since typical monitors are 60Hz, this interval would be 1 or 2 frames (16,6 or 33,3 ms). I tried doing this with usual WinForms, and it is not possible because, apparently, there is no way to know how many frames were output to the monitor since some point in time. I can only draw on the controls, and monitor output is totally independant. So even if I run the timer, say, for 17 ms, between showing and hiding the image, it still sometimes manages not to draw a single frame of my image on the screen (even though theoretically it should, because 17ms 16,6ms). Moreover, even 20ms seems to slow (even though i should be more than enough). I did some game development as a hobby in the past (Delphi X, XNA) and I know that you usually draw the whole screen by yourself, each frame. Also, I know that there is an option called Vsync in most modern games, that allows you to synchronize your framerate to your monitor's frame rate. So, is it possible? I mean, to actually know how many frames were sent to the monitor with w/e I want to show?

• What's the best practice for taking MySQL dump, encrypting it and then pushing to s3?

  - by HalogenCreative

  This current project requires that the DB be dumped, encrypted and pushed to s3. I'm wondering what might be some "best practices" for such a task. As of now I'm using a pretty straight ahead method but would like to have some better ideas where security is concerned. Here is the start of my script: mysqldump -u root --password="lepass" --all-databases --single-transaction > db.backup.sql tar -c db.backup.sql | openssl des3 -salt --passphrase foopass > db.backup.tarfile s3put backup/db.backup.tarfile db.backup.tarfile # Let's pull it down again and untar it for kicks s3get surgeryflow-backup/db/db.backup.tarfile db.backup.tarfile cat db.backup.tarfile | openssl des3 -d -salt --passphrase foopass |tar -xvj Obviously the problem is that this script everything an attacker would need to raise hell. Any thoughts, critiques and suggestions for this task will be appreciated.

• How should I implement multiple threads in a game? [duplicate]

  - by xerwin

  This question already has an answer here: Multi-threaded games best practices. One thread for 'logic', one for rendering, or more? 6 answers So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Hyper-V R2: Need help with disk structure

  - by MojoDK

  Hi all, I'm going to use the free (non gui) version of Hyper-V R2. In my new server I have 8 disks in total (for Hyper-V R2 installation and virtual machine). Atm I'm going to run a single virtual machine, with following tasks: Windows Server 2008 R2 x64 File/Print SQL Server My question is ... with my 8 disks in the server, which disks should contain wich data? Should I install "Hyper-V R2" and VM's drive c on same physical disks? Should I use raid 1 or 5? With the above tasks, how would you structure the disks? Hope you know what I mean (I'm not english, so it's difficult to explain). Thanks!!! Mojo

• mongodb eating 48G in 1min

  - by ledy

  In mongodb i work with this collection: Size 55.93g Data Size 39.82g Storage Size 41.08g Extents 53 Indexes 4 Index Size 9.64g It takes few seconds of mongdb being up with this single collection and all 48GB RAM on the dedicated server are gone. That's worse because there is also a mysqld+nginx/fcgi on this machine which should be allowed to use at least 24GB together. I.e. remaining 24GB, enough for the mongod! However, it does not share in a fair way. Everybody says that the memory for mongod is managed by OS and releases unneccessary space for other processes if they demand RAM. On my machine it is not releasing RAM. What's wrong? free total used free shared buffers cached` Mem: 49559136 49403908 155228 0 57284 47247564 -/+ buffers/cache: 2099060 47460076 Swap: 8008392 164 8008228

• SharePoint 3.0 Search Stuck Starting

  - by Skaughty

  I have a single server running SharePoint 3.0 on WS2003 Sp2 not on a domain. My search service stopped working so I just went in to central admin and hit stop, then hit start. I soon found out this is not the way to do this process. I now can not get the search service to start again. I have tried everything I can think of, and nothing works it changes status to Starting but never gets to started. I have to go in with "stsadm -o spsearch -action stop" from the command prompt to stop it. I am using the Local service account for the service and the content accounts. Can anyone help me?

• What function should I use in Excel for searching a (multiple) text string?

  - by Alenanno

  The title is a bit unclear, but I'll be explaining it now for better clarity. I have this: When I type in the Input field, I'd like Excel to show me the result in the Output field. For example, if I write Four, I'd like it to output 20, or if I write one of the other three words, then 12. The problem is that... I can't make it to work. The formula I tried is "=CERCA(C2;G:G;H:H)" (cerca means search), so I'm saying "Take what I write in the cell C2, search through the column G and give me what you find from the column H", but the result is always N.D. (Not available). I've tried other combinations and: Text strings, does not work; Single numbers, works (if I search 1, it says 2, which is what I expect); multiple numbers, does not work (if I search 4, nothing happens). What function should I use?

• Which UPS, for home use, which can automatically shutdown the PC when battery is low?

  - by Tony_Henrich

  I am planning to build a single server machine which is highly dependent on data residing in RAM for performance reasons. I am looking for a UPS which can power the PC during a blackout (very rare) and when the battery level is like %20, it sends a signal to Windows 2008 to shutdown. Even if it's only for a few minutes, that's good enough. This is for home use so I am looking for an inexpensive unit ( less than $300? ). Which brand/model is good choice? I prefer one whose battery is easily & cheaply replaced.

• Why does my Microsoft Habu force me to unplug and replug in when booting up?

  - by jordsta

  I'm not too sure why, but every single time I boot my computer, I have to unplug and replug my semi-new Microsoft Habu, when I use Windows 7. Why does it do this? I've been through my BIOS, msconfig, and what-not.. It just seems to happen all the time. I've even looked in forums, with people resorting to changing their mouse because of the same issue.. It's stupid. Hopefully someone else can help... hopefully someone with experience with this mouse.

• How can I limit other (administrator) users access to my profile?

  - by kojo

  Hi, We in our club have a computer with Windows 7 Professional that every club member may use. And everyone has their own separate account. Those accounts have to have administrator priveleges since I want everyone to be able to install any software and use any feature they want. However, there is a single thing that they shouldn't be allowed to do - that is, look into another users' profiles. Now when anyone goes to 'c:\Users(Any User Name)' a little prompt appears that this folder is secured and whether you really want to look inside. Simply clickinh 'ok' give you access to any profile. I tried disabling taking ownership for Administrators group in Group Policies but that had no effect. How can I effectively prohibit administrators looking into each others' profiles and documents?

• WHY Google does not ban these sites using this SEO pattern? [on hold]

  - by saddam.bg

  I have seen some sites using a different kind of SEO to promote copyrighted materials such as movies. They also have submitted their site to Google webmaster tools but still now did not get banned. Their Alexa ranks are 7000 or less. On the other hand I have run 5 movie affiliate sites and all of them got banned by Google within a short period of time. I have copied the url of the homepage of solarmovie.me and pasted it on the google search and instead of the homepage url I have seen that their category or tag shows as the homepage (www.solarmovie.me/watch-category/hollyw... Now is solarmovie.me publishing its posts as a single page or something else? I tried to find out what kind of SEO or coding that was, but I couldn't since I have very little knowledge about coding. Also I have seen the same thing with ALLUC.TO in google search (www.alluc.to/popular-links.html). Could anyone please help with the SEO of this kind so that I don't get banned by google frequently or index removed. All SEO webmaster i need your help!!!! Please give me some good tips for this type of SEO. Thank You Very Much

• What do desktop users use SSD for? [closed]

  - by Continuation

  I keep hearing people say how much faster their desktops/laptops are after switching to SSD. But then when I ask them what do they use SSD for, the answers are always "booting". Not trying to start a flame war here. I use SSD for my database server and it makes a huge difference. A single SSD can replace a 10 drives RAID 10 and is actually both much faster and MUCH CHEAPER. But I just can't think of a usecase for desktops where SSD could make a similar impact. Sure it's kinda nice to cut boot time down from 40 seconds to 10 seconds. But is it that big a deal? Would love to hear how SSD improves your desktop performance.

• What is the best way to browse the web safely? [closed]

  - by cedivad

  At the recent pwnown we saw every single browser, from IE to Chrome, miserably hacked. That scares me. How should we browse the Internet safely but continuing to enjoy it? (using lynx is not an option) Virtual machines? Different users with non-administrative privileges? Keep the work and "Facebook" on 2 separate machines? (or on 2 hard disks, invisible each other?) I think that they should write a book on the matter.
