  • Multiple "My Documents" folders?

    - by Flasimbufasa
    I am having the issue, where, I have 2 folders called "My Documents". I recently edited my registry to make "Document" link in the Windows 7 start menu be a FOLDER link and not a LIBRARY link.. Here is the Registry Key information for the Documents key: Key Name: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{7b0db17d-9cd2-4a93-9733-46cc89022e7c} Class Name: <NO CLASS> Last Write Time: 3/2/2011 - 2:33 AM Value 0 Name: Attributes Type: REG_DWORD Data: 0x1 Value 1 Name: Category Type: REG_DWORD Data: 0x4 Value 2 Name: Icon Type: REG_EXPAND_SZ Data: %SystemRoot%\system32\imageres.dll,-1002 Value 3 Name: LocalizedName Type: REG_EXPAND_SZ Data: @%SystemRoot%\system32\shell32.dll,-34575 Value 4 Name: Name Type: REG_SZ Data: Documents Value 5 Name: PublishExpandPath Type: REG_DWORD Data: 0x1 Value 6 Name: PrecCreate Type: REG_DWORD Data: 0x1 Value 7 Name: RelativePath Type: REG_SZ Data: Documents Value 8 Name: Roamable Type: REG_DWORD Data: 0x1 Also, Navigating through computer to "C:\Users\Flasimbufasa\" Only shows one folder called "Documents" However, whenever I navigate to user profile from "Desktop\Flasimbufasa" I get 2 Document folders.

  • I don't understand the definition of side effects

    - by Chris Okyen
    I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?

  • Why to say, my function is of IFly type rather than saying it's Airplane type

    - by Vishwas Gagrani
    Say, I have two classes: Airplane and Bird, both of them fly. Both implement the interface IFly. IFly declares a function StartFlying(). Thus both Airplane and Bird have to define the function, and use it as per their requirement. Now when I make a manual for class reference, what should I write for the function StartFlying? 1) StartFlying is a function of type IFly . 2) StartFlying is a function of type Airplane 3) StartFlying is a function of type Bird. My opinion is 2 and 3 are more informative. But what i see is that class references use the 1st one. They say what interface the function is declared in. Problem is, I really don't get any usable information from knowing StartFlying is IFly type. However, knowing that StartFlying is a function inside Airplane and Bird, is more informative, as I can decide which instance (Airplane or Bird ) to use. Any lights on this: how saying StartFlying is a function of type IFly, can help a programmer understanding how to use the function?

  • Unable to Mount an external hard drive (NTFS)

    Ubuntu 11.10. When I plug my external Drive Western Digital MyPassport (500Go NTFS) I named WD.

  • Which web site gives the most accurate indication of a programmer's capabilities?

    - by Jerry Coffin
    If you were hiring programmers, and could choose between one of (say) the top 100 coders on topcoder.com, or one of the top 100 on stackoverflow.com, which would you choose? At least to me, it would appear that topcoder.com gives a more objective evaluation of pure ability to solve problems and write code. At the same time, despite obvious technical capabilities, this person may lack any hint of social skills -- he may be purely a "lone coder", with little or no ability to help/work with others, may lack mentoring ability to help transfer his technical skills to others, etc. On the other hand, stackoverflow.com would at least appear to give a much better indication of peers' opinion of the coder in question, and the degree to which his presence and useful and helpful to others on the "team". At the same time, the scoring system is such that somebody who just throws up a lot of mediocre (or even poor answers) will almost inevitably accumulate a positive total of "reputation" points -- a single up-vote (perhaps just out of courtesy) will counteract the effects of no fewer than 5 down-votes, and others are discouraged (to some degree) from down-voting because they have to sacrifice their own reputation points to do so. At the same time, somebody who makes little or no technical contribution seems unlikely to accumulate a reputation that lands them (even close to) the top of the heap, so to speak. So, which provides a more useful indication of the degree to which this particular coder is likely to be useful to your organization? If you could choose between them, which set of coders would you rather have working on your team?

  • How to test the tests?

    - by Ryszard Szopa
    We test our code to make it more correct (actually, less likely to be incorrect). However, the tests are also code -- they can also contain errors. And if your tests are buggy, they hardly make your code better. I can think of three possible types of errors in tests: Logical errors, when the programmer misunderstood the task at hand, and the tests do what he thought they should do, which is wrong; Errors in the underlying testing framework (eg. a leaky mocking abstraction); Bugs in the tests: the test is doing slightly different than what the programmer thinks it is. Type (1) errors seem to be impossible to prevent (unless the programmer just... gets smarter). However, (2) and (3) may be tractable. How do you deal with these types of errors? Do you have any special strategies to avoid them? For example, do you write some special "empty" tests, that only check the test author's presuppositions? Also, how do you approach debugging a broken test case?

  • Can Windows 7, Vista, or XP notify me after 30 minutes, or at 2:30pm?

    - by Jian Lin
    Come to think about it, since Windows 3.0, Windows 95, 2000, ME, XP, Vista, and Windows 7, does any Windows have a capability of giving a "beep beep" notification to me, let's say I need to go meet somebody after 30 minutes? Or give a "beep beep" at 2:30pm? I hope to hear some sound instead of a pop up window as I may be writing something on the desk instead of looking at the computer. I usually don't want to install 3rd party app for this purpose, as you never know what the app does or how trustworthy it is if it is not a popular app (like Firefox or Safari). Does any version of Windows come with that capability? I'd imagine it is an app that takes two days to write.

  • yahoo media player not working

    - by luca590
    I have a yahoo media player embedded in my webpage. I am currently using Ruby on Rails to create/edit my web page. When i click the play button next to a track the YMP waits a while and then goes to the next track without playing the first one. I then get a warning on my second (last) track that its file could not be found. Does anyone has a better recommendation for an audio player or a way to fix this one?

  • How often is seq used in Haskell production code?

    - by Giorgio
    I have some experience writing small tools in Haskell and I find it very intuitive to use, especially for writing filters (using interact) that process their standard input and pipe it to standard output. Recently I tried to use one such filter on a file that was about 10 times larger than usual and I got a Stack space overflow error. After doing some reading (e.g. here and here) I have identified two guidelines to save stack space (experienced Haskellers, please correct me if I write something that is not correct): Avoid recursive function calls that are not tail-recursive (this is valid for all functional languages that support tail-call optimization). Introduce seq to force early evaluation of sub-expressions so that expressions do not grow to large before they are reduced (this is specific to Haskell, or at least to languages using lazy evaluation). After introducing five or six seq calls in my code my tool runs smoothly again (also on the larger data). However, I find the original code was a bit more readable. Since I am not an experienced Haskell programmer I wanted to ask if introducing seq in this way is a common practice, and how often one will normally see seq in Haskell production code. Or are there any techniques that allow to avoid using seq too often and still use little stack space?

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

    I attempted to do a logical volume resize yesterday using the follwoing commands $sudo pvdisplay "/dev/sda8" is a new physical volume of "113.11 GiB" --- NEW Physical volume --- PV Name /dev/sda8 VG Name PV Size 113.11 GiB Allocatable NO PE Size 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID jwyO1o-b2ap-CW51-kx7O-kf26-arim-SM8V6m $sudo vgextend vg /dev/sda8 sudo vgdisplay vg --- Volume group --- VG Name vg System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 9 VG Access read/write VG Status resizable MAX LV 0 Cur LV 5 Open LV 5 Max PV 0 Cur PV 2 Act PV 2 VG Size 131.74 GiB PE Size 4.00 MiB Total PE 33725 Alloc PE / Size 4769 / 18.63 GiB Free PE / Size 28956 / 113.11 GiB VG UUID AhusW2-pzFv-3W32-mpv2-s5VG-FN7S-kVSadx $sudo lvresize -L +20GB /dev/mapper/vg-var So as you can see, it looks like adding the physical volume to the vg worked, because i see free space available there. When I typed the lvresize command, it never returned. I let this run overnight in the background, but this morning I still couldnt successfully do a "pvdisplay" or "lvdisplay" because I think it was waiting on a lock or something, so the command never returned. When i went to log onto the server's console, I saw a bunch of messages like: rcu_sched_state detected stall on cpu 2 Now when I boot, I get a kernel panic error, and a message about not being able to mount /mapper/vg-root cannot open root device "mapper/vg-root" or unknown_block(0,0) Kernel Panic -not syncing: VFS: Unable to mount root file system on unknown_block(0,0) What should I do to get my system back up and running? Did I attempt to do the logical volume resize correctly? Thanks

  • Web Hosting Checklist

    - by Chris
    Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

  • Connecting to wireless networks from command line

    - by Balaji
    I need to write a shell script which connects to one of the two available wi-fi connections. One is a un secure connection and the other is secure connection. My question has 2 parts- 1.How to connect to the un-secure (un-encrypted and no password required) connection from command line (or by executing a shell script) when I'm connected to the secure connection? I followed the steps in http://www.ubuntugeek.com/how-to-troubleshoot-wireless-network-connection-in-ubuntu.html for in-secure connection. I put all the commands in a script and executed it (I made sure that interface name and essid are correct) - sudo dhclient -r wlan0 - sudo ifconfig wlan0 up - sudo iwconfig wlan0 essid "UAPublic" - sudo iwconfig wlan0 mode Managed - sudo dhclient wlan0 But nothing happens - I'm not disconnected from the current network and connected to the new one 2.When I want to connect to the secure wi-fi network, I understand from http://askubuntu.com/a/138476/70665 that I need to use wpa_supplicant. But I enter a lot of details in the interface when I connect via UI security : wpa and wpa2 enterprise Authentication : PEAP CA certificate : Equifax... PEAP version : automatic inner authentication : MSCHAPv2 username : password : How to use wpa_supplicant to mention all these details in the command line? The conf file network={ ssid="ssid_name" psk="password" } doesn't work for me.

  • backface culling error (in world space)

    - by acrilige
    I write simple software renderer. In my pipeline i have stage of backface culling. But looks like it has some error (see picture). I perform culling right after world transformation (is it correct?). (i can't insert picture in post coz i don't have enough points, so i just upload it (cube model): http://imageshack.us/photo/my-images/705/bcerror.png/) Vector3F view_dir(0.0f, 0.0f, 1.0f); std::vector<Triangle> to_remove; for (Triangle &t : m_triangles) { Vector4F e1 = t.v2 - t.v1; Vector4F e2 = t.v3 - t.v1; Vector3F normal( e1.y * e2.z - e1.z * e2.y, e1.z * e2.x - e1.x * e2.z, e1.x * e2.y - e1.y * e2.x ); normal.Normalize(); float dot = Dot(view_dir, normal); if (dot <= 0) to_remove.push_back(t); } for (Triangle& t : to_remove) m_triangles.erase(std::remove(m_triangles.begin(), m_triangles.end(), t), m_triangles.end()); Camera sits in origin and points in screen (RH). What is the reason? For better explanation i upload picture with cube rotation screenshots: http://imageshack.us/photo/my-images/842/bcmove.png/ UPDATED: The error occurs only when triangle has non-zero offset from origin UPDATED 2: If i process backface culling in clip space (after transforming all vertices with view and projection matrix), and just check z coordinate of triangle normal - it works perfect... Can i perform culing RIGHT BEFORE view/proj transforms? In this case looks like culling will not depends of projection and it's not right?.. UPDATED 3: I found answer and will post it in two hours - again coz of reputation lack.

  • Is there a smarter Find files utility for Windows 8 than Windows key + F?

    - by Clay Shannon
    Is there any utility for Windows 8 that will basically do the same thing the old "Find" dialog in Explorer did? Often times (many times a day) I need to find a particular file, and I don't know the name of it or where it is, but I can remember a phrase in it, and approximately when it was written, e.g., it has the phrase "Duckbilled Platypus" in it and was written sometime in the last week. The Find Files functionality in Windows 8 is lame by comparison; I know there are probably geeky ways to jump through hoops and do it, but I don't want to have to write GREP expressions, I want something easy like the old functionality...

  • How do I get this Mac OS X exposé behavior?

    - by quangtruong1985
    In Mac os x, I can move all windows to the nearest corner by hitting F11 key. I'm just wondering if there is a compiz plugin works like that. I know that there is Scale plugin already. But all that I want is something like this. You'll see, press a key and all windows fly off to nearest corner so I can drag/drop file or do something else on my desktop, then press the key again and all windows fly back.
