• connecting to bsnl wll, with huawei fixed wireless modem with connected to usb port on linux mint.

  - by Rakesh

  On windows, when I plugged in the usb connector, to the device was recognized as a mass storage device and installed all the drivers, to my computer, then the device, automatically restarted and started behaving like a modem, I'm writing this post, using the same modem, through windows... On linux mint (debian kernel, similar to ubuntu 8.10), the device is recognized as a mass storage device, some times, but, has no programs, useful for linux... When I use the modem on windows and restart the computer and login to linux, the device shows up as "not yet configured" in the terminal command "lsusb"... I googled a lot for solutions, tried many things, atlast, configured it and run the command "wvdial". But, get the error, that the modem is not responding, at last ! :'( Please help me out... Many more people are facing this problem, as I could discover, when I googled for it. this is the website address of huawei, the company of my modem... "www.huawei.com" Specification: model: ETS1220 FEQ: 800M Thank you.

• Server Firewall preventing sending of email [migrated]

  - by Jo Fitzgerald

  The firewall on my VPS appears to be preventing my site from sending email. It was working fine until the end of last month. My hosting provider (Webfusion) has been next to useless. I am able to send email if I open INPUT ports 32768-65535, but not if these ports are closed. Why would this be? I have the following rules in my firewall: # sudo iptables -L Chain INPUT (policy DROP) target prot opt source destination VZ_INPUT all -- anywhere anywhere Chain FORWARD (policy DROP) target prot opt source destination VZ_FORWARD all -- anywhere anywhere Chain OUTPUT (policy DROP) target prot opt source destination VZ_OUTPUT all -- anywhere anywhere Chain VZ_FORWARD (1 references) target prot opt source destination Chain VZ_INPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:www ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:ssmtp ACCEPT tcp -- anywhere anywhere tcp dpt:pop3 ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpts:32768:65535 ACCEPT udp -- anywhere anywhere udp dpts:32768:65535 ACCEPT tcp -- localhost.localdomain localhost.localdomain ACCEPT udp -- localhost.localdomain localhost.localdomain Chain VZ_OUTPUT (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere ACCEPT udp -- anywhere anywhere The VPS is running Plesk 10.4.4 (please ask if you require further technical information to help me)

• Have a legitimate Windows 7 license and the Windows 7 key but don't have the DVD

  - by sonicboom

  I just booted up my 'old' PC that's been lying around for the last two years. I have Windows 7 on it and I'm looking to format the drive and do a fresh install of W7. I have the key for Windows 7 in a text file. However I don't have the Windows 7 DVD or image. So is there any way of burning off a Windows 7 DVD considering that its the operating system I'm currently using? If not...well I have a W7 key, will this key work with any W7 DVD or is it particular to the W7 image that came with the key?

• Slow dvd burning/reading speeds: how to solve

  - by wouter205

  I have a problem on which I'm struggling since i started using linux a year ago on my desktop, but still haven't found a solution for it. When reading or burning a dvd, the speeds are very slow (mostly under 1x) whilst I did selected the fastest speed in k3b. As such, it takes up to 40-50 minutes to burn one dvd! I read about enabling dma this post but it didn't help. This is the output for dmesg | grep -i dma > [ 0.000000] DMA 0x00000010 -> 0x00001000 [ 0.000000] DMA32 0x00001000 -> 0x00100000 [ 0.000000] DMA zone: 56 pages used for memmap [ 0.000000] DMA zone: 5 pages reserved [ 0.000000] DMA zone: 3921 pages, LIFO batch:0 [ 0.000000] DMA32 zone: 3527 pages used for memmap [ 0.000000] DMA32 zone: 254441 pages, LIFO batch:31 [ 0.000000] Policy zone: DMA32 [ 0.120356] pnp 00:01: [dma 4] [ 0.120968] pnp 00:05: [dma 2] [ 0.121421] pnp 00:06: [dma 3] [ 0.122617] pnp 00:0b: [dma 0 disabled] [ 0.852321] ata1: SATA max UDMA/133 cmd 0xec00 ctl 0xe480 bmdma 0xe000 irq 19 [ 0.852325] ata2: SATA max UDMA/133 cmd 0xe400 ctl 0xe080 bmdma 0xe008 irq 19 [ 0.861633] ata3: PATA max UDMA/133 cmd 0x1f0 ctl 0x3f6 bmdma 0xff00 irq 14 [ 0.861636] ata4: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xff08 irq 15 [ 1.329411] ata1.00: ATA-7: Maxtor 6V250F0, VA111630, max UDMA/133 [ 1.345418] ata1.00: configured for UDMA/133 [ 1.820606] ata4.00: ATAPI: PHILIPS DVDR1660P1, P1.3, max UDMA/33 [ 1.820610] ata4.00: WARNING: ATAPI DMA disabled for reliability issues.

• Windows Remote-App Server 2012 Office 2013 User Settings not saved

  - by dave

  I have a Windows Server 2012 with RemoteApps enabled. It's running the latest Patches etc. It has Office 2013 installed and Excel and Word are shared to all users. Now I got the Problem that after each Reboot all User Settings are lost. I have a few users who pin previously opened Documents so they dont need to remember all Paths and those are all gone after Reboot. Also last opened Documents is empty and after a Server reboot it brings the office 2013 Window for First time setup where it asks if you want to connect to skydrive and all that. In the RemoteApps Collection I enabled a Userprofile-Drive 100GB drive E: for Storing User profile data. There is a Domain of course and there is no GPO Preventing the user from Storing settings etc. We also got an older Terminal Server 2003 in the same Domain where this is not happening. Any ideas why this is happening that all the Settings are lost after Reboot?

• Programming as a minor

  - by Tomas Cokis

  Hello Everyone! I've never asked a question here at programmers, and for reasons which will become obvious later I've never answered one here, but I do poke around in short bursts. Anyway, I'm 15 right now, and I've been programming in C++ for 4 years, just working on my own projects that are aim so high as to never be finished. I've been working on a single project for the last year, and every 3 months, I add a new system into it. It might be a value tabling directory enabled log system, or a render system, or a class to load up xml files, whatever it is, I don't mind too much that the overall project (a 3d engine) isn't ever going to get finished, I just get some satisfaction from getting what I have done building and running. I don't know what I want to do when I grow up, although I suspect I'll go into some form of engineering, but I was interested in knowing if I do choose to go into a career as a developer, what kind of material I could look at to push myself up and get myself experience that might help my career later. I'm not talking about books in particular, I'm more interested in subjects areas that will get me access to good job opportunities, or that will give me a hand-up if I do computer science and software related courses at uni. One of the things I was thinking of doing was designing some of the logic gate components of a small computer - which I started briefly over the holidays, working out integer addition, subtraction and multiplication. That kind of stuff interests me, but is it really useful - or more useful then just more programming? But anyway, Any advice? Should I continue on my perpetual 3d engine? Are there any other projects or particular accomplishments that would help my education? Perhaps I should mention that I live in Perth, Australia, so local software companies are likely to be more scarce then usual.

• Can AJAX in a CMS slow down your server

  - by Saif Bechan

  I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.

• Documentation often ommits to specify which flavour of regular expression to use, so is there a default flavour that we should all be familiar with?

  - by JW01

  Often I come across documentation that says "use a regular expression here" I have to spend quite some time digging around trying to work out which regular expression format they are expecting. As far as I can tell, there are many types of regular expression. But, at my last place of work I was made to feel stupid when I suggested adding some text to our User Documentation to specify the type of regular expression to be used. When someone says "a regular expression" what is the regular expression syntax most people expect and where is it documented? Update: I was prompted to single-out some examples - but no disrespect to these great projects: eregi docs page is not particularly helpful in explaining expected syntax. Nor can I easily work out the syntax expected here if i just land on the page from a search. No explicit mention of the regular expression pattern expected by PatternExpectation() on the SimpleTest page. etc. etc. here is a highly voted SO answer that seems to assume there is only one flavour of regular expressions.

• What is the correct term for - server/client database sync via API?

  - by Daniel

  Forgive the vague question title. I've been programming mobile apps for 3 years now, and I've got a little too far from the web services and server side code then I probably should have. Anyway, I'm doing a personal project now and I want to create an web API for it. One of my requirements is to check for updates from my app, so I would send a timestamp to the API. I've used many APIs that my clients prepared for me and only now am I appreciating their work ! What is the term or technique used to create an API backed by a database which tracks changes via dates/timestamps, basically an effective way for me to query changes occurring since a timestamp. Simply put, I want that my app can call my API in order to sync new data and changed data from the server, to the app. The app would only have a timestamp of the last time it synced with the server. Would I have a log table for each data table in my database which adds a record for each change? Then I could query all changes with a timestamp superior to the one passed to the API. Can anyone point me in the right direction on this?

• Unit testing statically typed functional code

  - by back2dos

  I wanted to ask you people, in which cases it makes sense to unit test statically typed functional code, as written in haskell, scala, ocaml, nemerle, f# or haXe (the last is what I am really interested in, but I wanted to tap into the knowledge of the bigger communities). I ask this because from my understanding: One aspect of unit tests is to have the specs in runnable form. However when employing a declarative style, that directly maps the formalized specs to language semantics, is it even actually possible to express the specs in runnable form in a separate way, that adds value? The more obvious aspect of unit tests is to track down errors that cannot be revealed through static analysis. Given that type safe functional code is a good tool to code extremely close to what your static analyzer understands. However a simple mistake like using x instead of y (both being coordinates) in your code cannot be covered. However such a mistake could also arise while writing the test code, so I am not sure whether its worth the effort. Unit tests do introduce redundancy, which means that when requirements change, the code implementing them and the tests covering this code must both be changed. This overhead of course is about constant, so one could argue, that it doesn't really matter. In fact, in languages like Ruby it really doesn't compared to the benefits, but given how statically typed functional programming covers a lot of the ground unit tests are intended for, it feels like it's a constant overhead one can simply reduce without penalty. From this I'd deduce that unit tests are somewhat obsolete in this programming style. Of course such a claim can only lead to religious wars, so let me boil this down to a simple question: When you use such a programming style, to which extents do you use unit tests and why (what quality is it you hope to gain for your code)? Or the other way round: do you have criteria by which you can qualify a unit of statically typed functional code as covered by the static analyzer and hence needs no unit test coverage?

• How does this game loop actually work?

  - by Nicolai

  I read this playfulJS post, about ray-casting: http://www.playfuljs.com/a-first-person-engine-in-265-lines/ It looks really interested, so I decided to look at his javascript. I am no expert in javascript, so I quickly got lost. It's the game loop "object" that really gets me. I simply don't understand how it works. From the code: function GameLoop() { this.frame = this.frame.bind(this); this.lastTime = 0; this.callback = function() {}; } GameLoop.prototype.start = function(callback) { this.callback = callback; requestAnimationFrame(this.frame); }; GameLoop.prototype.frame = function(time) { var seconds = (time - this.lastTime) / 1000; this.lastTime = time; if (seconds < 0.2) this.callback(seconds); requestAnimationFrame(this.frame); }; var loop = new GameLoop(); loop.start(function frame(seconds) { map.update(seconds); player.update(controls.states, map, seconds); camera.render(player, map); }); Now, what really confuses me here, is this bind stuff and how this actually loops. I am guessing, that if less than 0.2 seconds have passed, since the last time the loop was run, it simply goes back to re-check the time. If more than 0.2 seconds have passed, it leaves the frame function, and executes the 3 lines in the loop. But, if this is true, then how does the loop.start() get called again? And what on earth is the meaning of this.frame = this.frame.bind(this);? I've looked up prototypes bind() but I really don't understand it.

• Raspberry Pi: mvoe home & var folders to USB HDD?

  - by doni49

  I have a Raspberry Pi running raspian. I've installed Apache2, PHP & MySQL. Apache & MySQL are both configured to use sub-directories of /var. I'd like to use a directory on my USB HDD instead of my SD card. I'd also like to move the /home directory to the USB HDD. I'd like to avoid re-partioning my HDD if possible. I thought maybe I could use a symlink to tell raspian that /var is really at /media/USBHDD1/var and /home is really at /media/USBHDD1/home. I tried it last night but couldn't get it to work.

• Microsoft Entourage/Exchange Server problem: all objects disappeared from server - still in some for

  - by splattne

  One of our employees works with Entourage on his MacBook Pro (OSX 10.6) accessing Exchange Server 2007. Last Friday morning, I think while working over a VPN, Entourage (I think it was Entourage) deleted all his objects (mail, calendar, contacts) on the server and while creating a lot of strange folders (starting with underscores) on the client. The local data seems to be there, but not in a consistent form. Since the user's mailbox is rather big, I suspect, that there was some kind of "move" operation which did not complete. I tried to export the data, but the export stops because of a corrupted object. Is there a tool or another way to export or retrieve the local data? Edit - FYI: we solved the problem getting his data from the previous night's backup.

• Some Nice Icon Themes for Ubuntu [on hold]

  - by Saurav Kumar

  Last night I was searching for some good looking icon themes availabe for Ubuntu, but unfortunately could not find any post which gives a list of themes :(. From yesterday night I started searching icons themes and installing one by one. So thought to share some of them hope it will help others to get a bunch of them in one post. This is a Q&A-Style tutorial which will cover: Few good icon themes which are used in famous Ubuntu type distros and are available in repository. Look and feel through pictures. How to easily install? I also request others to share their experiences of some awesome icon themes. Once themes are installed Ubuntu-Tweak will help to change and manage them, since I could not find another way to change the themes in Unity. In xfce(Xubuntu) it can be changed from Appearance. Just believe me this post will not be vast. If I'll remove pictures then it will become small, but it will not look good. Please give suggestion to make it small.

• Virtualbox PXE Boot Failing with a Windows Server 2008 R2 Server

  - by Vbitz

  Some fast help on this would be good, I have been on this problem for 14 hours. In a Virtualbox test environment I have 2 virtual machines networked together using a internal network (no traffic runs though the host, it is all at a software level). One is a fresh client with 512mb of ram and a dual core set-up, the other is the server with 1.5GB of ram and running server 2008 r2. The server is configured as a dns server, dchp server, domain controller and also serves PXE booting though WDS (Windows Deployment Services). Both machines can see each other and I am able to start a network boot. The issue comes at the second to last stage of the pre windows PE install. On TFTP download of boot.sdi it starts it but stops during the boot process.

• Apache gzip with chucked encoding

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recived, but then after ungzipping I see that response is partial. So my question is: is it common apache issue? maybe one of it's mod_deflate plugins or something? Ask questions if you need more info. Thanks.

• Can i enlarge os c drive of my windows 8? [migrated]

  - by Sorgatz

  Last year I got a new Western Digital WD Blue 500GB HDD to replace my old drive. The first thing I did was to install latest Windows 8. While installing Windows 8 I created 3 partitions, C drive for the OS and others for storage. The OS partition is 120GB (which at the time I thought would be plenty big) but I'm now realizing its too small! I wonder if it's possible to re-size HDD partition without reformatting and re-install my Windows 8. So that is my question, Can i enlarge os c drive of my windows 8 without having to re-format? I've used the Norton Partition Magic and Disk Management to make this happen but there doesn't seem to be any options to make it happen. Thanks for any help you guys can give regarding my question. I've worked hard to optimize my current install of Windows 8 and would hate to start all over again.

• Coding Dynamic Events?

  - by Joey Green

  I have no idea what the title of this question should be so bare with me. My game has turns. On a turn a player does something and this can result in a random number of explosions that occur at different times. I know when the explosions are done. I need to know when ALL are done and then do some other action. Also, each explosion is the same amount of time, say 3 seconds.. Right now I'm thinking of using a counter to hold how many explosions are happening. Then once the explosion is finished decrement this counter. Once the counter is zero, do my action. This idea is inspired by objective-c memory management btw. Anyways, does this sound like a good approach or would there be another way. An alternative might be to figure out the explosion who happened last and let it be responsible for calling this subsequent action. I'm asking mostly, because I haven't done this before and am trying to figure out if there are bugs that may occur that I'm not foreseeing.

• Some problems after running ubuntu tweak application

  - by sachin

  I am a first time user of ubuntu 12.04 and must say that i am enjoying it. Somehow my skype on ubuntu is screwed up. The message that i am getting says (Disk IO error). Did any one face the problem before. Also i downloaded the ubuntu tweak application. After that application has clean some file, the application it self is not starting now.. I am quiet new to linux much and fear that if the tweak application has cleaned some files which were necessary.

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.
