• Word to GIMP pasted image too small

  - by Marcelo Cantos

  I paste an image from Microsoft Word 2010 into GIMP 2.6.10 using Edit ? Paste as ? New Image, but the pasted image is less than half-size (1280×800 down to 553×347). Pasting into an existing blank 1280×800 image makes no difference. On the other hand, pasting exactly the same clipboard entry into Windows Paint works beautifully, producing a razor-sharp 1280×800 image, and furthermore, pressing Ctrl+C in Paint, then going to Gimp and pressing Shift+Ctrl+V in Gimp produces the correct full-size image in Gimp too. Why does pasting an image directly from Word to Gimp reduce the image size? How can I make it paste the correct image size without having to go via Paint? UPDATE: I just noticed that cutting the image from Word and pasting back into the same document also loses definition. Paint must be magical.

• When can I publish a software tool written at work?

  - by AlexMA

  I'm working on a software problem at work that is fairly generic, but I can't find a library I like to solve it, so I'm considering writing one myself (at least a bare-bones version). I'll be writing some if not all of the 1.0 version at work, since I need it for the project. If turns out well I might want to bring the work home and polish it up just for fun, and maybe release it as an open-source project. However, I'm concerned that if I wrote the 1.0 version at work I may not be allowed to do this from a legal sense. Obviously I could ask my boss (who probably won't care), but I'm curious how other programmers have dealt with this issue and where the law stands here. My one sentence question is, When is it okay (legally/ethically) to open-source a software tool originally written by you for work at work? What if you have expanded the original source significantly during off-hours? Follow-up: Suppose I write the whole thing at home on my time then simply use it at work, does that change things drastically? Follow-up 2: Note that I'm not trying to rip off my employer (I understand that they're paying me to build products that they own)--I'm just wondering if there's a fair way of doing this for all involved... It would be nice if some nonprofit down the road could use my code and save them some time. Also, there's another issue at stake. If I write the library for a very simple, generic thing (like HTML tables in Javascript), does that mean I can never again do so on my own time without putting myself at legal risk (even if it was a whole new fresh rewrite or a segment of a larger project). Am I surrendering my right to write code for this sort of project for the rest of my life (without this company's permission), since the code at work might still be somewhere in my brain influencing me? This seems related to software patents, as a side-note.

• Android 2D terrain scrolling

  - by Nikola Ninkovic

  I want to make infinite 2D terrain based on my algorithm.Then I want to move it along Y axis (to the left) This is how I did it : public class Terrain { Queue<Integer> _bottom; Paint _paint; Bitmap _texture; Point _screen; int _numberOfColumns = 100; int _columnWidth = 20; public Terrain(int screenWidth, int screenHeight, Bitmap texture) { _bottom = new LinkedList<Integer>(); _screen = new Point(screenWidth, screenHeight); _numberOfColumns = screenWidth / 6; _columnWidth = screenWidth / _numberOfColumns; for(int i=0;i<=_numberOfColumns;i++) { // Generate terrain point and put it into _bottom queue } _paint = new Paint(); _paint.setStyle(Paint.Style.FILL); _paint.setShader(new BitmapShader(texture, Shader.TileMode.REPEAT, Shader.TileMode.REPEAT)); } public void update() { _bottom.remove(); // Algorithm calculates next point _bottom.add(nextPoint); } public void draw(Canvas canvas) { Iterator<Integer> i = _bottom.iterator(); int counter = 0; Path path = new Path(); path.moveTo(0, _screen.y); while (i.hasNext()) { path.lineTo(counter, _screen.y-i.next()); counter += _columnWidth; } path.lineTo(_screen.x, _screen.y); path.lineTo(0, _screen.y); canvas.drawPath(path2, _paint); } } The problem is that the game is too 'fast', so I tried with pausing thread with Thread.sleep(50); in run() method of my game thread but then it looks too torn. Well, is there any way to slow down drawing of my terrain ?

• Can I replace a router and DHCP server without disrupting traffic?

  - by SRobertJames

  I have a device which acts as a router and DHCP server. I'm replacing it, and would like to minimize down time. If I unplug it, and plug in a different device with the same IP, will all the PCs with DHCP leases keep on working? (I have DHCP Conflict detect on, so it shouldn't reassign a DHCP address already used). What if I want to change the IP (new subnet) - is there anyway to tell all the clients (Windows PCs) to release their DHCP leases and request new ones in a minute? If before unplugging the old device, I have it release all DHCP leases, will the Windows PCs automatically ask for new DHCP addresses?

• SEO questions about PR, Page Structure, and Other

  - by jasondavis

  A couple of basic questions related to SEO. 1) If I have a site that has several different niches that I am trying to promote from. Example Web Developer broke down into section of Web Design, Graphic Design, Programming, Software for SEO purposes, would it be better to use subdomains for these main sections or use the main domain with a folder like structure? 2) Is PR different for each page of a domain or ever page has a PR of the same on that domain? Also do sub-domains have a different PR? 3) When entering a hugely over saturated niche such as web-design, is it even possible to compete with the big sites that have been ranked on google #1 page for years? 4) Lastly, I have read about how important titles, link anchors, and headings are for SEO and how content is the most important. So left's say we are building a standard header, body, sidebar, footer page. In the the actual markup, would it be better to make sure the main content comes before the sidebar on the page or does this probably not make a difference? 5) I seen mentioned in another answer here that microformats can help with SEO, is there any fact behind this? Thank you for any info on this

• .NET app - Should we use SQL Server and duplicate some reference data from an external Oracle DB? Or use Oracle and have a DB link?

  - by Daventry

  We're looking to migrate some existing Excel/Access processes into a new system which will provide the users with a Silverlight frontend to run and view the reports instead of using MS Access. The initial idea was to have SQL Server 2008 as RDBMS. The problem is that we've got some static data such as country codes, counterparties, etc which live in an existing Oracle DB. Since we do not want to duplicate that data (if possible), we were thinking of having a DB link between SQL Server and Oracle, but our firm does not allow that. So the options are either duplicate the data or use Oracle as RDBMS - surprise, the firm does allow DB links between Oracle databases. The initial idea was also to use WCF RIA Services, Entity Framework, etc which we're not sure they play well with Oracle, that's why it was decided to go with SQL Server in the first place. Would you advise to go for Oracle so that we can just link the static data? Or use SQL Server 2008 and replicate it because it's "safer" to stay within the Microsoft land? To use or not to use Entity Framework and WCF RIA Services at all? Regards. UPDATE: Thanks everyone for your answers. Nothing is set in stone yet. We'll try to import the data instead of linking, as if the other DB goes down, our system can still carry on. We're likely to use SQL Server just because most developers are more experienced with it. Even if we used RIA Services, we can swap out the Data Access Layer and use other frameworks such those mentioned below.

• Hosting and domain registrations for multiple clients

  - by letseatfood

  I am finally getting regular work desiging, developing, and deploying websites for small businesses and individuals. So far the websites utilize single-user content management systems, so the websites create, as far as I know, minimal load on the shared servers. I have always required that each of my clients purchase annual shared hosting at Dreamhost. For domain registration, I ask that they register with Dreamhost, but some already have a registered domain elsewhere and this is fine with me. I do this so the billing issues are the client's responsibility, not mine. My question is: Since I can register unlimited domains and connect them to my one shared hosting account at Dreamhost, should I not be requiring clients to individually pay for shared hosting and a domain? Should I actually be paying for one hosting account and then hosting all of my client's websites on that account? As I said before, I currently have each client buy their own hosting, because I feel that, for example, if there is high traffic to their site, there would be less a chance of the site going down than if their site was hosted with many others on one account. I am famous for being long-winded, please let me know if I can clarify at all. Thanks!

• Infected Win XP disk not openable on a Vista computer

  - by Retired57

  How can I read a WinXP partioned disk that is infected and shows up on a USB connection to Win Vista computer as a single partition that Vista cannot see the contents? The XP computer HDD is partioned into 4 partitions. It became infected, and all attempts to clean it have failed. Applications begin to launch, but are then shut down by the infecting agent. Using a major Anti-virus Co. boot disk (which was unable to connect to the Web, probably because the infecting agent stopped it) with virus definitions dated after the disk became infected, the resultant scan showed no infection. I bought a USB cable to connect the IDE drive to my Vista computer, but when I open Win Explorer, it sees the disk, but does not show any contents. It indicates it is a single partition that is valid. However in all the ways I have tried it does not show drive contents. Any suggestions on what to do next?

• XNA - 2D Rotation of an object to a selected direction

  - by lobsterhat

  I'm trying to figure out the best way of rotating an object towards the directional input of the user. I'm attempting to mimic making turns on ice skates. For instance, if the player is moving right and the input is down and left, the player should start rotating to the right a set amount each tick. I'll calculate a new vector based on current velocity and rotation and apply that to the current velocity. That should give me nice arcing turns, correct? At the moment I've got eight if/else statements for each key combination which in turn check the current rotation: // Rotate to 225 if (keyboardState.IsKeyDown(Keys.Up) && keyboardState.IsKeyDown(Keys.Left)) { // Rotate right if (rotation >= 45 || rotation < 225) { rotation += ROTATION_PER_TICK; } // Rotate left else if (rotation < 45 || rotation > 225) { rotation -= ROTATION_PER_TICK; } } This seems like a sloppy way to do this and eventually, I'll need to do this check about 10 times a tick. Any help toward a more efficient solution is appreciated.

• How do Unity 12.04/Compiz bindings really work?

  - by Daniel

  There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

• How can I redirect URLs using the proxy module in Apache?

  - by LearningIT

  This seems like a super-basic question but I am having a hard time tracking down a straightforward solution, so appreciate any help and patience with me on this: I want to configure my Apache proxy server to redirect certain URLs so that, for example, a web browser HTTP request for www.olddomain.com gets passed to the proxy server which then routes the request to www.newdomain.com which sends a response to the proxy server which then passes it back to the web browser. Seems so simple, yet I don't see how to achieve this on Apache. I know Squid/Squirm offer this functionality so am guessing I am missing something really basic. I know I can use RewriteRule to dynamically modify the URL and pass it to the proxy server, but I effectively want to do the reverse, whereby the proxy server receives the original URL, applies the RewriteRule, and then forwards the HTTP request to the new URL. Hope that makes sense. Thanks in advance for any help.

• How can I regress a number series in Excel?

  - by jcollum

  I'd like to use these data to derive an equation using Excel. 300 13 310 12.6 320 12.2 330 11.8 340 11.4 350 11 360 10.8 370 10.6 380 10.4 As x goes up, y goes down. Seems straightforward. But when I do a polynomial regression on these data, even though the trendline matches the data pretty well, the equation it generates doesn't work. The equation is When I plug in x values to that equation, the numbers go up! So something is pretty wrong here. My steps: place both number series in excel select the second set (13, 12.6 ...) plot a line graph set the first set as the x axis labels select Series1 and add a polynomial (2) trendline, display equation, display R-squared That produces the equation above, with an R^2 value of .9955. But when I use that equation, it doesn't produce those outputs for those inputs. Clearly I'm doing something wrong.

• How to resolve problematic vnc/xming clipboard interaction?

  - by frankc

  I often have both a VNC client window and several X windows open (via Xming) at the same time on my Windows XP desktop. When this happens, the X windows, especially emacs and firefox, often lock up or behave erratically. I am pretty sure I have narrowed this down to contention over the clipboard. I wasn't really able to find any options controlling this behavior in either Xming or VNC. Is there a solution to this problem? Right now, I have to close VNC when I am actively using emacs...

• How do I start Chrome using a specified "user profile"?

  - by Danny Tuppeny

  I use the new built-in "Users" feature of Chrome to switch between Home/Work accounts easily. However, Chrome remembers the "last" user profile you had selected when launching new windows. This is a problem if I close down my "Home" profile last, because when I then click the Email shortcut on my taskbar, because it goes to mail.mycompany.com using my Home profile, and I'm not logged in. I'd like to change the shortcut to the company webmail to pass a switch that tells Chrome to always start as the "Default" user, regardless of the last one used. Note: I have tried user-data-dir, and this seems to do something very different, completely isolated from the Users functionality built in to Chrome. It's possible I'm using it wrong, but please test this before assuming it does the same thing and posting an answer ;-)

• Copy a single file from main directory recursively across all directories within

  - by chris

  I'm on a dedicated server using CentOS, and on this server I have 5000+ directories in one main directory. In the main directory I have an index.php. I would like to copy this index.php into all 5000+ directories, but the only way I know how is doing it manually. Is there a way through the command line that I can enter something like cp and make it work from the directory? I'd copy it all the way down through all the directories and there sub directories within this main directory I am starting out in.

• Rack processes taking over CPU under Passenger

  - by pjmorse

  I have a Spree site running the following stack: Nginx 1.0.8 Passenger 3.0.9 Ruby 1.9.2-p290 Rack 1.3.6 Rails 3.1.4 Spree 0.70.5 I recently upgraded from Spree 0.70.3, which also brought a Deface upgrade from 0.7.x to 0.8.0. Since then things have been very unstable. Recently we've seen some CPU-hogging processes which drive load up on the server and grind the whole thing to a stop. They're Rack processes and it looks like Passenger is starting them; they're owned by the site-runner user, an unprivileged user who owns the application code. (Passenger automatically runs the site code as the user who owns it.) If I restart Nginx and kill the runaway processes, it helps for a while, but eventually similar processes return and bog things down again. How can I figure out what's starting these processes, what they're trying to do, and how to stop them?

• C++ program...overshoots? [migrated]

  - by Zdrok

  I'm decent at C++, but I may have missed some nuance that applies here. Or maybe I completely missed a giant concept, I have no idea. My program was instantly crashing ("blah.exe is not responding") about 1/5 times it was run (other times it ran completely fine) and I tracked the problem down to a constructor for a world class that was called once in the beginning of the main function. Here is the code (in the constructor) that causes the problem: int ii; for(ii=0;ii<=255;ii++) { cout<<"ent "<<ii<<endl; entity_list[ii]=NULL; } for(ii=0;ii<=255;ii++) { cout<<"sec "<<ii<<endl; sector_list[ii]=NULL; } entity_list[0] = new Entity(0,0); entity_list[0]->_world = this; Specifically the second for loop. The cout references are new for the sake of telling where it is having trouble. It would print the entire "ent 1" to "ent 255" and then "sec 1" to "sec 255" and then crash right after, as if it was going for a 257th run through of the second for loop. I set the second for loop to go until "ii<=254" which stopped all crashes. Does C++ code tend to "overshoot" for loops or something? What is causing it to crash at this specific loop seemingly at random? By the way, entity_list and sector_list point to classes called Entity and Sector, respectively, but they are not constructing anything so I didn't think it would be relevant. I also have a forward declaration for the Entity class in a header for this, but since none were being constructed I didn't think it was relevant either. EDIT: It was due to the new Entity line, I assumed wrongly that the fact that altering the for statement to 254 fixed the crashes meant that it had to be there. I still don't understand why the for loop is related, though.

• 2 DSL lines...any benefit?

  - by EJB

  I have verizon DSL in my office, I put DSL in about a year ago for $29.95 month...I added a new phone line recently and it was cheaper to actually get it bundled with DSL so now I have two DSL lines...my plan was to shut the first one off when my 1 year contract comes up (in September). A couple of times DSL has gone out on one line so I just used the other, which is a nice redundancy to have - but it doesn't happen often. (I unplugged one line and plugged in the other) Question is, is there any way to use both DSL lines together so that 1) I can increase bandwidth and effective speed might increase (is that possible?) or 2) have them both on and connected someway so that traffic on my network would just use either one, and if one went down the traffic would route automatically? If I can either increase speed by having two, or at a minimum get some automatic redundancy, I see no reason to keep both on.... Thanks!

• Best VoIP VPS Location?

  - by ToiletOverflow

  Our office currently runs a few phones over a VoIP line. Through our VoIP provider, we have a virtual private server. We chose them as the VPS provider because the VPS came pre-loaded with all of the software that was necessary. However, I've discovered that I would rather manage the software myself and would prefer to work on a different platform. The primary reason that we have stayed with them is because as our VoIP provider, I presume that there is some advantage in call quality because they have "direct access to the PSTN", which I would presume is an advantage when it comes to call termination and overall call quality. My question boils down to: What is better from a call quality perspective? 1) A server located 20ms closer to us (60ms), offered by a different company. 2) The current server at the VoIP/SIP provider (80ms)

• Apache crashing at random intervals. Can not find a reason in log files

  - by Nick Downton

  We are having an issue with a VPS running plesk 9.5 on ubuntu 8.04 At seemingly random intervals Apache will disappear and needs to be started manually. I have checked the apache error log, /var/log/messages, individual virtual host apache error files and cannot find anything that coincides with the time of the failure. dmesg is empty which is a bit odd. We have also had the psa service go down for no apparent reason but apache stay up. I'm at a loss to diagnose this really because all the log files I can find do not point to any issues. Are there any others I can look at? Memory usage sits at about 55% (out of 400mb) and it isn't a particularly high trafficed server. Any pointers as to where else I can find out what is going on would be very much appreciated. Nick

• How can I disrupt my roommate's BitTorrent?

  - by bob

  We're on a 50 mb/s Comcast connection and our connection right now is coming in under 1.5 mb/s. Our roommate left for a week with BitTorrent running (Azureus client, we think). Our latency is approaching 300 ms. His door is locked up tight, and both his machine and the router for the house are located inside. I've even flipped the power breaker in the house and that barely works for 2 minutes. His laptop keeps on running, and once the cable modem and router come back up and the machine reconnects, the torrents resume in earnest. I've been running nmap and identified his IP on our LAN. Is there anything I can do over the LAN to make his torrents start to fail or slow down?

• How to handle sorting of complex objects?

  - by AedonEtLIRA

  How would one sort a list of objects that have more than one sortable element? Suppose you have a simple object Car and car is a defined as such: class Car { public String make; public String model; public int year; public String color; // ... No methods, just a structure / container } I designed a simple framework that would allow for multiple SortOptions to be provided to a Sorter that would then sort the list. interface ISorter<T> { List<T> sort(List<T> items); void addSortOption(ISortOption<T> option); ISortOption<T>[] getSortOptions(); void setSortOption(ISortOption<T> option); } interface ISortOption<T> { String getLabel(); int compare(T t1, T t2); } Example use class SimpleStringSorter extends MergeSorter<String> { { addSorter(new AlphaSorter()); } private static final class AlphaSorter implements ISortOption<String> { // ... implementation of alpha compare and get label } } The issue with this solution is that it is not easily expandable. If car was to ever receive a new field, say, currentOwner. I would need to add the field, then track down the sorter class file, implement a new sort option class then recompile the application for redistribution. Is there an easier more expandable/practical way to sort data like this?

• Sticky Load Balancing with AWS

  - by John Wheal

  I have just setup a load balancer with AWS for a few instances as search engine crawlers were bringing down the site (it has millions of pages). Parts of the site allow you to login so I selected: Enable Application Generated Cookie Stickiness and everything works fine. I now wonder how this will effect my SEO and the crawlers. As I selected sticky load balancing does this mean that a crawler will be stuck on one server and therefore defeat the point in the load balancer? Any recommendations will be appreciated.
