• Should I be concerned that I can't program very fast without Google? [closed]

  - by seth

  Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

• Visual Studio 2012 window border leaks onto other screen

  - by chrisstuart

  I have several 30" monitors and as a result, I use the Win+Left/Right to tile windows to the left and right side of each screen. I've noticed an annoying feature of Visual Studio 2012 is that it seems to "leak" onto the next screen. I can see a line on the adjacent screen as if the edge of the window is slightly over the border. Anyone else see this? Is it a bug? This is on Windows 7 64 bit. I've never seen this with any other application.

• b43 Firmware Error when trying to install Ubuuntu 14.04 on XP Laptop

  - by WizardNo.7

  I know I'm an Ubuntu and Linux n00b, but I've been browsing the web for a few days searching for a solution, and none of the other b43 posts etc solve my problem. I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(It's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed(which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers, and then I get the usual: [ 95.514833] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found [ 95.514847] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found [ 95.514855] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all the instruction on this website. After this I have to hard reboot or shut-down. I don't have a previous Linux install so cannot do the apt-get from my previous install. I cannot access the boot options menu by using F6 or similar. Any ideas? Thanks beforehand!

• Problem with dual monitor

  - by Gernot

  I have a laptop with a nvidia optimus graka. I'm also useing a 23" external monitor. It never really worked... . After installation (it was a clean installation) the 23" monitor worked as it should, but the LCD from the laptop wasn't at the right resolution. And every time i tried to change this the PC crashed. Today i had a litle bit of time so i decided to solve this problem. I've tried a few things ( e.g. I've installed bumblebee with the nvidia driver and tested it. It's working...) but nothing solved my problem. Instead of getting any closer to the solution, it's gotten even more strange now... . Now, the display setting isn't recognizing a 2nd monitor at all. But I get on the 23" monitor (which is not shown in the display setting) a screen with the same resolution as the one on the laptop. The display settings looks so: Any help would be wonderful.

• Using 2d collision with 3d objects

  - by Lyise

  I'm planning to write a fairly basic scrolling shoot 'em up, however, I have run into a query with regards to checking for collision. I plan to have a fixed top down view, where the player and enemies are all 3d objects on a fixed plane, and when the enemy or player fires at the other, their shots will also be along this fixed plane. In order to handle the collision, I have read up a bit on collision detection in 3d, as it is not something I have looked into previously, but I'm not sure what would be ideal for this situation. My options appear to be: Sphere collision, however, this lacks the pixel precision I would like Detection using all vertexes and planes of each object, but this seems overly convoluted for a fixed plane of play Rendering the play screen in black and white (where white is an object, black is empty space), once for enemies and once for the player, and checking for collisions that way (if a pixel is white on both, there is a collision) Which of these would be the best approach, or is there another option that I am missing? I have done this previously using 2d sprites, however I can't use the same thinking here as I don't have the image to refer to.

• Make services not start automatically after reboot (as they require access to an encrypted partition)

  - by Binary255

  Hi, I use Ubuntu Server 10.04. I more or less only want the server to be accessible over SSH after a reboot. I will then login and mount the encrypted partition myself, after which I start the services which uses it. How would I go about setting something like that up? (My first idea was to have everything except /boot in an encrypted LVM, but I never got logging in through SSH and mounting the LVM to work. Initramfs was a bit too complicated for me. Otherwise I think this would have been the best solution.)

• Workaround broken sudo?

  - by perreal

  I managed to break sudo by deleting the libc.so.6 sym-link in /lib. I copied the actual file and created a symbolic link with the same name under my home directory by using LD_PRELOAD=/lib/libc-2.11.3.so. At this point, all binaries linking libc are working through preload except sudo. For sudo, I need to write (and don't know why): $ /lib/ld-linux-x86-64.so.2 --library-path . /usr/bin/sudo but this gives me: $ sudo: must be setuid root Checking the permissions: $ ls -l /usr/bin/sudo $ -rwsr-xr-x 2 root root 166120 So the setuid bit is actually set. Question: I need to create a symbolic link named /lib/libc.so.6 through my active ssh connection without using sudo, or, make sudo work somehow. I don't have the root password and I can't connect through ssh anymore. Is there any other way I can get authorization?

• ADF Hands on Training &ndash; Prerequisites for 22nd March 2011

  - by Grant Ronald

  For those of you coming to the ADF Hands on training on the 22nd March in London, there was a link to the prerequisites.  Unfortunately, in a reshuffle of content on OTN, this page was removed.  So, over the next day or so I’m hoping to the pull together the relevant information into this blog post.  So keep checking back! Firstly, you need to being your laptop with you to do the hands on exercises.  No laptop, no hands on. Recommended 2GB RAM running Microsoft Windows XP SP2, 2003 Server SP2, Vista (32 bit only), Windows 7 or Linux or Mac 2GHz Processor (less will be acceptable but slower) Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher, Google Chrome 1.0 or higher Winzip or other extracting software Adobe Acrobat reader Flash (if you want to see dynamic graphs in your application) As for software, you will need have installed JDeveloper 11g.  The hands on instructions are based on 11.1.1.2 (or is it 11.1.1.3)! anyway, either of those or 11.1.1.4 would be required. You also need an Oracle database on your machine and access to the HR schema (which should be unlocked).  Don’t expect to have access to a network and VPN to a database. A simple test, unplug your laptop from your corporate network, run up JDev  and select File –> New –> Database connection and make sure you can connect to HR database and see the Emp/Dept etc tables.  If you can do that, you should be good to go. I would strongly recommend ensuring you have this in place before you arrive on Tuesday. Look forward to seeing you there.

• Safe to use high port numbers? (re: obscuring web services)

  - by sofakng

  I have a small home network and I'm trying to balance the need for security versus convenience. The safest way to secure internal web servers is to only connect using VPNs but this seems overkill to protect a DVRs remote web interface (for example). As a compromise, would it be better to use very large ports numbers? (eg. five digits up to 65531) I've read that port scanners typically only scan the first 10,000 ports so using very high port numbers is a bit more secure. Is this true? Are there better ways to protect web servers? (ie. web guis for applications)

• What precaution should I take to hire online freelancer designers? [on hold]

  - by tomDev

  For quite some time my company is super busy with our apps, and a few days ago someone contacted me by email offering his services to help me as a graphic designer. He has a fair price, a flickr portfolio (with great stuff but not popular at all), same on Twitter. I was really considering in hiring him for some specific service, but the question is... what precaution should I take when hiring someone I have no idea who is? I can't even be sure I have his real name and his real country. How do I make a contract? How do I pay? How do I know he will not sue us after the graphics reach the App Store asking for more money? And of course, how do I know he will actually do the service and not steal from some stock service? Am I a bit paranoiac or is this a common deal with graphics designers? PS: if someone asks I can provide his flickr, but I think this is a general question and not specific for this designer.

• moving in the wrong direction

  - by Will

  Solution: To move a unit forward: forward = Quaternion(0,0,0,1) rotation.normalize() # ocassionally ... pos += ((rotation * forward) * rotation.conjugated()).xyz().normalized() * speed I think the trouble stemmed from how the Euclid math library was doing Quaternion*Vector3 multiplication, although I can't see it. I have a vec3 position, a quaternion for rotation and a speed. I compute the player position like this: rot *= Quaternion().rotate_euler(0.,roll_speed,pitch_speed) rot.normalize() pos += rot.conjugated() * Vector3(0.,0.,-speed) However, printing the pos to console, I can see that I only ever seem to travel on the x-axis. When I draw the scene using the rot quaternion to rotate my camera, it shows a proper orientation. What am I doing wrong? Here's an example: You start off with rotation being an identity quaternion: w=1,x=0,y=0,z=0 You move forward; the code correctly decrements the Z You then pitch right over to face the other way; if you spin only 175deg it'll go in right direction; you have to spin past 180deg. It doesn't matter which direction you spin in, up or down, though Your quaternion can then be something like: w=0.1,x=0.1,y=0,z=0 And moving forward, you actually move backward?! (I am using the euclid Python module, but its the same as every other conjulate) The code can be tried online at http://williame.github.com/ludum_dare_24_evolution/ The only key that adjusts the speed is W and S. The arrow keys only adjust the pitch/roll. At first you can fly ok, but after a bit of weaving around you end up getting sucked towards one of the sides. The code is https://github.com/williame/ludum_dare_24_evolution/blob/cbacf61a7159d2c83a2187af5f2015b2dde28687/tiny1web.py#L102

• How do I know if my disks are being hit with too much IO reads or writes or both?

  - by Mark F

  Hi All, So I know a bit about disk I/O and bottlenecks relating to this especially when relating to databases. But how do I really know what the max IO numbers will be for my disks? What metric might be available to me for working out roughly (but needs to be a good approximation) of how much capacity (if you will) have I got left available in I/O. I've seen it before where things are bubbling along nicely and then all of a sudden, everything screams to a halt, and it ends up being an IO bound problem. Is there a better way to predict when IO is reaching its limits? This article was interesting but not giving the answer I desire. "http://serverfault.com/questions/61510/linux-how-can-i-see-whats-waiting-for-disk-io". So is my best bet surrounding just looking at 'CPU IO WAIT'? There must be a more reactive method for this? Best, M

• what do you use for storage discovery / storage management?

  - by lysdexic

  I am looking for some ideas on what would be the best way to discover and manage network storage. Discovery: Any good tools that will scan hosts and storage devices and report back their findings? Maybe using SNMP or WMI? Management: I'm currently looking at Storage Manager by Solar Winds, but it is a bit pricey. Any good open source projects like this? Just looking for ideas of how to get better visibility into the storage infrastructure on this network. It includes a HP Lefthand Iscsi san and EC VNX san. As well as individual hosts with local storage. Thanks for reading and thanks for any input.

• Circumventing a manual HTML login page for "unclassified" websites (automation purposes, credentials

  - by auramo

  The IT department just made my life a little bit harder again: they introduced a manual HTML login page for all websites they have not "classified". This means that all the applications which try to access unclassified websites for e.g. downloading plugins do not work. Examples: Eclipse plugin installation, Maven builds etc. What would be the easiest workaround for this? The best I've come up with is try to extend/customize Ruby's httpproxy.rb that comes with Webrick. I would automate the manual login process whenever that login response page is detected. This sounds quite painful, and I think there might/should be simpler options?

• Equalizer for Toshiba Satellite Pro Laptop (Windows 7) (has Realtek sound)

  - by Need Help

  Hi, I've been trying to find a way to have a real equalizer for my Toshiba Satellite Pro Laptop. I don't know much about computers but the guys in the store seem to know less than I do! From what I've been able to glean through friends, Windows 7 no longer supports a real equalizer function with Realtek, and the result is a fake "equalizer" that does nothing. I have hearing issues so not being able properly adjust the higher frequencies is causing me physical pain and ringing in my ears. I've tried to decipher the threads I find online but am quite confused by them. Basically I need an equalizer that will work with Windows 7 (with everything, internet, skype, music, etc). The current drivers offered by Realtek do nothing except make the sound inaudible. The one that may possibly work and provide an actual equalizer is a few versions back and can't be found anywhere. Thanks! And sorry if this is a duplicate question but I am confused a bit by the threads online.

• WINAPI window management question

  - by gekod

  I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

• Grepping through the results of apachectl -S

  - by CamelBlues

  I have a server with about 300 virtual hosts. When I want to make sure a specific httpd.conf file is loaded into the Virual Host config and the syntax is correct, I run apachectl -S. The problem is, though, I get a ton of output. I've tried apacectl -S | grep 'foo' and apachectl -S > foo.txt to try and make this data a little bit more manageable, but the output of the command is not conducive to grepping or shoving into a text file. When I try apachectl -S | grep 'foo', it simply returns the entire output of apachectl -S. When I try apachectl -S > foo.txt, foo.txt is an empty file. This may have something to do with how the server is configured, because I am able to successfully grep on my local machine. Any suggestions?

• From the Coalface - 3 - Work as hard as you can to be as lazy as you can!

  - by TATWORTH

  The saga of the Change Log A recent conversation reminded me of the need for change logs within a database, to record when various change scripts were run. Creating such the required table is simple. A typical table for this consists of: Id - identity Integer primary key ChangeFileName - NVARCHAR(128) to hold the name of the file run. DateAdded - DateTime non-null with default value of getutcdate() Purpose - NVARCHAR(128) Rerunnable - Bit non-null default 0. By good design of the table only two data values normally need to be supplied. Two stored procedures, one for inserting data and one to list in reverse sequence the log complete the database essentials. The complete implementation can be found in the CommonData solution at http://CommonData.CodePlex.Com By including a call the add Change Log stored procedure, each script can log its name and purpose for posterity. The scripts that were applied to say the UAT system and their sequence of application can be readily identified for running on the Live system. Formatting XML XML is often produced as one continous string with no embedded CR/LF. To get it into human readable form, open it in visual studio, swap to another tab and back and click the format document button. The XML will then be nicely formatted!

• Should I use my real name in my open source project?

  - by Jardo

  I developed a few freeware programs in the past which I had signed with my pseudonym Jardo. I'm now planning to release my first open source project and was thinking of using my full real name in the project files (as the "author"). I thought it would be good to use my name as my "trademark" so if someone (perhaps a future headhunter) googles my name, they'll find my projects. But on the other side, I feel a bit paranoid about disclosing my name (in the least case I could be getting a lot of spam to my email, its not that hard to guess your private email from your name). What do you think can be "dangerous" on disclosing your full name? What are the pros and cons? Do you use your real name or a pseudonym in your projects? I read this question: What are the advantages and disadvantages to using your real name online? but that doesn't apply to me bacause it's about using your real name online (internet discussions, profiles, etc.) where I personally see no reason to use my real name... And there is also this question: Copyrighting software, templates, etc. under real name or screen name? which deals with creating a business or a brand which also doesn't apply to me because I will never sell/give away my open source project and if someone else joins in, they can write their name as co-author without any problems...

• Web application access different between Domain Name and IP

  - by h82

  in our office, we have a web application running. When we access the application by the domain name, http://server.domain.com/application/name it will display the current version of application. However, when we go by the IP address, http://192.168.1.111/application/name it will display the old version of that application. One thing is that we can access that application either by http://server.domain.com/ (it will be redirected to the long URL automatically) or http://server.domain.com/application/name when we are using domain name. But only accessible via the exact URL when we use IP address. Why is it showing the old version and how can it be corrected? It is running JRun4, Apache on Red hat. I've checked in httpd.conf a bit but could not find any. Please advice what should be done to display the same (updated version) when we access using domain name or IP address. Thank you.

• I use windows7 and am looking for a tool to help me tag/organize my bookmarks as well as my thoughts and projects.

  - by tomcat23

  I've got my bookmarks in Chrome currently, and am prone to just bookmarking something if it contains any info I may need for the project I'm currently working on. I had found a way to tag them with delicious and then get an export from that into a wordpress test server (with the tags), having a post for each bookmark, but this proved to be a bit of a waste of time, as there's no way to organize it well. Ideally I'd like to find some sort of mind-mapper with a Prezi-like view, that does auto tagging, excerpting and allows me to notate things effectively. Does my dream tool even exist? I've usually got 20+ tags open all at once because there may be something open on each I need to see/know to make my current project work. It's frustrating. Though I'm on Win7, I'm interested to hear about any tools that are out there that work to take your existing bookmarks and help you organize them productively.

• Can Remote Desktop connect only 2 monitors when the client has 3 or 4 monitors connected?

  - by user12931

  I have three monitors (all 1920x1200) connected to my desktop and I would like to RDP into another computer (running Windows Server 2003) and use only two of my three monitors. The main monitor is used for notification from the LAN like email, build status, etc. I've tried modifying the .rdp file to have a higher resolution (i.e. 3840x1200 ) which sort of works but the bits per pixel goes down to 8 and you have to manually resize the window which means that you need to change it to around 3840x1150. If I supply /span to the commandline it gives me a bit more than 3840 spanned across the three monitors (is there perhaps a limitation of say 4096 for the maximum resolution?). WORKAROUND: Connect twice to the same computer. Here's an interesting post from Microsoft: http://blogs.msdn.com/b/rds/archive/2009/08/21/remote-desktop-connection-7-for-windows-7-windows-xp-windows-vista.aspx

• Snapshot/Save GPU Drivers

  - by ashes999

  Since I'm running XP/32-bit, my GPU drivers are quite fragile. I've spent several hours trying to back up and restore from old versions, on at least two separate occasions. Writing down the device drivers is not enough. In the short term, I would like to somehow save, zip, backup, snapshot, or something so that if I need to reinstall my OS in the short-term, I have a reliable way to get the drivers. ATI's website doesn't have the install kit anymore, and I don't have it saved; I googled, but didn't find the exact same version. How can I backup/save my drivers so that I can reinstall them later?
