• What are some easy techniques to scan books for new information?

  - by aditya menon

  I find it irresistible to keep purchasing cheap programming and technical e-books in fields such as Drupal, PHP, etc., and also compulsively download free material made available such as those from Microsoft's developer blog... The main problem with the large library I've developed is that there are many chapters (especially the first few) in these books packed with information I already know, but with helpful tidbits hidden in between. The logical step would be to skip those chapters and read the ones I don't seem to know anything about, but I'm afraid I may lose out on really important information this way. But naturally it is tedious to have to read about variables, functions and objects all over again when you are trying to know more about the Registry pattern, for example. It's hard to research on the net for this, because my question itself seems vague and difficult to formulate into a single search query. I need people-advice - what do you do in this situation?

• How to disable three finger gestures on touchpad?

  - by oznah

  I am using 12.04 on a macbook pro. Everything works really well. I want to disable 3 finger gestures. It is way to easy to accidentally drag/move a window(3 finger gesture) while scrolling(2 finger gesture) when using a touchpad. I found this answer on ask ubuntu. It was marked answered but it is not. The functionality is still there. All this recommendation does is disable the drag marks on the window. This may be tricky because I want to disable 3 finger gestures but not 2 finger gestures. (ie I don't want to disable touchpad gestures all together)

• Spending the summer at camp Web Camp, that is

  Microsoft is sponsoring a series of Web Camps this summer. Theyre a series of free two day events being held worldwide, and Im really excited about being taking part. The camp is targeted at a broad range of developer background and experience. Content builds from 101 level introductory material to 200-300 level coverage, but we hit some advanced bits (e.g. MVC 2 features, jQuery templating, IIS 7 features, etc.) that advanced developers may not yet have seen. We start with a lap around ASP.NET...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How do I get a Netgear WNDA3100V2 working?

  - by Michal

  I have Ubuntu 11.10 on my desktop. A month ago I bought Linksys AE1000 adapter,I did not check that it's not working on Ubuntu and because I've lost receipt I'm stuck with it. Last week I bought Netgear adapter and this time I did check and it meant to be plug an play but it was not. I have checked many forums and managed to install software, system does sees adapter but it's not connecting to network. I have found that it may not like WPA so I have created my own password-letters and digits,no spaces-still nothing.I don't understand why. This is my next attempt with Linux and I'm not with IT background so it takes time and research before I can resolve something but I really want to learn. I so wish to learn on Ubuntu.One day, I've checked Fedora16 and my old Linksys AE1000 worked without any instalations.

• Can I remove "Free space" text from the Nautilus status bar?

  - by DisgruntledGoat

  I want to remove the part in Nautilus that shows free disk space. In theory it may useful but it's so badly designed, every time I select some files my eye gets drawn to "15 GB" instead of the actual size of the files. And with no files selected, it says something like "24 items, Free space 15GB" which at a quick glance looks like the total size of the files. I've looked through the preferences and don't see anything. I'm using Ubuntu 10.10 with Nautilus 2.32.0.

• Could not apply stored configuration for monitors

  Well this happened when I upgraded to Natty. Not only seems I can't change my resolution to higher than 1024x768 but it appears at the left and using only 70% of the monitor's width. I tried logging in but in ubuntu classic mode, and i was able to change it, but that trick did not work anymore. (May this be a compiz problem?)

• Unable to recognize hard drive after replacing a drive

  - by Peter Schriver

  I have a Poweredge 830 that I had been using with 1 OS Sata drive and 3 data drives. One of the drives had some failing sectors so I replaced it with a different drive. For some bizarre reason the computer would not reboot so I disconnected all of the media drives and did a clean reinstall on the OS drive. Only the boot drive and one of the media drives are now recognized by my Bios. Drive 0 and 2. Drive 1 and 3 are listed in the Bios as "Unkown Device" Any help would be appreciated I think there may be something wrong with the install. For some reason when I attempt to change the display it says I have a laptop.If you think a reinstall is in order I will try that.

• Filtering content from response body HTML (mod_security or other WAFs)

  - by Bingo Star

  We have Apache on Linux with mod_security as the Web App Firewall (WAF) layer. To prevent content injections, we have some rules that basically disable a page containing some text patterns from showing up at all. For example, if an HTML page on webserver has slur words (because some webmaster may have copied/pasted text without proofreading) the Apache server throws a 406 error. Our requirement now is a little different: we would like to show the page as regular 200, but if such a pattern is matched, we want to strip out the offending content. Not block the entire page. If we had a server side technology we could easily code for this, but sadly this is for a website with 1000s of static html pages. Another solution might have been to do a cronjob of find/replace strings and run them on folders en-masse, maybe, but we don't have access to the file system in this case (different department). We do have control over WAF or Apache rules if any. Any pointers or creative ideas?

• Skype support and dead parrot sketches

  - by Greg Low

  We as an industry have a lot to answer for. One thing is the level of support provided for users. Here's the conversation I'm having with Skype right now.

• How to learn what the industry standards/expectations are, particularly with security?

  - by Aerovistae

  For instance, I was making my first mobile web-application about a year ago, and half-way through, someone pointed me to jQuery Mobile. Obviously this induced a total revolution in my app. Rewrote everything. Now, if you're in the field long enough, maybe that seems like common knowledge, but I was totally new to it. But this set me wondering: there are so many libraries and extensions and frameworks. This seems particularly crucial in the category of security. I'm afraid I'm going to find myself doing something in a professional setting eventually (I'm still a student) and someone's going to walk over and be like, My god, you're trying to secure user data that way? Don't you know about the Gordon-Wokker crypto-magic-hash-algorithms library? Without it you may as well go plaintext. How do you know what the best ways are to maximize security? Especially if you're trying to develop something on your own...

• Installing Microsoft VX1000 webcam

  - by KRistian

  I found a tutorial with people saying it works; here are the instructions I followed. I opened a shell as root on my system and launched the following: wget http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.gz tar zxvf tip.tar.gz cd v4l... (whatever the newly created directory name is) make all sudo make install Then I edited /etc/modprobe.d/blacklist-custom and added blacklist sn9c102. After reboot, I launched sudo gstreamer-properties. However when I type tar zxvf tip.tar.gz it displays: tar: You may not specify more than one `-Acdtrux' or `--test-label' option Try `tar --help' or `tar --usage' for more information. Why? How can I do this? Thanks in advance.

• Problem in Kubuntu: Default browser never opens

  - by user170852

  I'm using Kubuntu, and I switched the default browser to my favourite one. The thing is, when I did this, both my Twitter clients stopped working. Now each and every Twitter client I download and install fails to open any web browser to finish my account authorization. It's impossible they're all broken, so I reset my default browser to rekonq and it works well as a default browser, but still can't login to twitter from any client. In fact, every button in every program that should open a browser window (like Amarok with the "like on last.fm" button) does nothing. So I think there may be a problem with my system but I can't figure out what is it. My user is not in the admin group (it's a shared user), I have an admin user but I only use it to install programs. Could that be the cause? Also, hitting alt+F2 and writing man:file (enter) opens a rekonq window normally.

• TTS on App Engine

  - by yati sagade

  I have written a small front-end to the Festival TTS system using Python/Django. I wish to deploy it on the Google App Engine cloud. A few questions: My application uses the Festival app 'text2wave'. Will is work on the cloud? I have used Python primitives like subprocess.call() to invoke the aforementioned program. Will that work? If your answer to any or both of (1) and (2) is no, is there a free api on the web that I can use (from the appengine)? I read somewhere about placing calls from Phono to a Voxeo backend, but I'm not sure what that means. I am aware of the Google Translate extension that allows translation using an HTTP GET (REST) request, but here the text is limited to 100 chars. Bad. Plus, they may take it down any point of time.

• Is there really Object-relational impedance mismatch?

  - by user52763

  It is always stated that it is hard to store applications objects in relational databases - the object-relational impedance mismatch - and that is why Document databases are better. However, is there really an impedance mismatch? And object has a key (albeit it may be hidden away by the runtime as a pointer to memory), a set of values, and foreign keys to other objects. Objects are as much made up of tables as it is a document. Neither really fit. I can see a use for databases to model the data into specific shapes for scenarios in the application - e.g. to speed up database lookup and avoid joins, etc., but won't it be better to keep the data as normalized as possible at the core, and transform as required?

• HTG Explains: What AppArmor Is and How It Secures Your Ubuntu System

  - by Chris Hoffman

  AppArmor is an important security feature that’s been included by default with Ubuntu since Ubuntu 7.10. However, it runs silently in the background, so you may not be aware of what it is and what it’s doing. AppArmor locks down vulnerable processes, restricting the damage security vulnerabilities in these processes can cause. AppArmor can also be used to lock down Mozilla Firefox for increased security, but it doesn’t do this by default.

• Historical origins of Scala implicits

  - by Frank

  Scala has been called complex with its rich feature set by many of my colleagues and some even blamed all those new features of it. While most programmers are aware of the OO-features, and at least the decent ones also know about functional programming, there is one feature in particular in Scala for which I am not aware of its historical origins. Given that a major mantra of our profession is to not reinvent the wheel, I am rather confident, that Scala does not have any actual unheard-of-before features, but I stand to be corrected on this one if necessary. To get to the actual question, while I am aware of the origins of most of Scala's features I have never seen something like its implicit declarations before. Are there other (older!) languages out there which also provide this feature? Does it make sense to distinguish the different cases of implicits (as they may originate from different sources), namely implict conversions and implicit parameters?

• How to Access Your Router If You Forget the Password

  - by Chris Hoffman

  Routers protect their web interfaces, where you can configure their networking, parental control, and port forwarding settings, with a username and password. These default passwords can be changed to protect the router’s settings. If you’ve forgotten a router’s password – or if you acquired a used router and don’t know its password – there’s a way to reset the password. You may also be able to forward ports without knowing the password.

• How to handle mutiple API calls using javascript/jquery

  - by James Privett

  I need to build a service that will call multiple API's at the same time and then output the results on the page (Think of how a price comparison site works for example). The idea being that as each API call completes the results are sent to the browser immediately and the page would get progressively bigger until all process are complete. Because these API calls may take several seconds each to return I would like to do this via javascript/jquery in order to create a better user experience. I have never done anything like this before using javascript/jquery so I was wondering if there was any frameworks/advice that anyone would be willing to share.

• How to access values of dynamically created TextBoxes

  - by SAMIR BHOGAYTA

  If one adds controls dynamically to a page and wants to get their information after PostBack, one needs to recreate these elements after the PostBack. Let's consider the following idea: First you create some controls: for(int i=0;i TextBox objBox = new TextBox(); objBox.ID = "objBox" + i.ToString(); this.Page.Controls.Add(objBox); } After PostBack, you want to retrieve the text entered in the third TextBox. If you try this: String strText = objBox2.Text; you'll receive an exception. Why? Because the boxes have not been created again and the local variable objBox2 simply not exists. How to retrieve the Box? You'll need to recreate the box by using the code above. Then, you may try to get its value by using the following code: TextBox objBox2; objBox2 = this.Page.FindControl("objBox2") as TextBox; if(objBox2 != null) Response.Write(objBox2.Text);

• Swap and hibernation

  - by maaartinus

  I saw a lot of recommendations claiming that for hibernation the swap partition/file must be at least as large as the main memory. This makes no sense to me. Lets assume I have 8 GB of main memory and 8 GB swap area and want to hibernate: case 1: I'm using 4 GB of virtual memory - 8 GB of swap is unnecessarily large. case 2: I'm using 8 GB of virtual memory - 8 GB of swap is just right. case 3: I'm using 12 GB of virtual memory - 8 GB of swap is too small. The outcome is: A swap area of size equal to the memory size is sufficient for hibernate IFF it doesn't get used for swapping at all. So what is the reason behind the claim that you need at least as much swap area as main memory for hibernate to work? I know that virtual memory gets used for caching too, and that the cache may be simply discarded, but what happens to hibernation if a program allocates 12 GB of virtual memory (given the above memory and swap sizes)?
