  • VSTO is Free But Aspose is Speed

    - by Ken Cox [MVP]
    I’ve taken over the completion, deployment, and maintenance of an ASP.NET Web site that generates Office documents using VSTO. VSTO’s a decent concept and works fine for small-scale scenarios like a desktop app or small intranet. However, with multiple simultaneous requests via ASP.NET, we found the Web server performance suffered badly. To spread out the server’s workload, I implemented MSMQ task queuing via a WCF Windows service.  That helped a lot. IIS didn’t drag with only one VSTO/Office instance running. But I  still found it taking too long to produce a single report. A nicely formatted VSTO Excel document was taking 45 minutes.  (The client  didn’t know any better and therefore considered 45 minutes tolerable.) On my own time, I pulled out an old copy of Aspose.Total for .NET. Within an hour, I had converted the VSTO Excel C# code to Aspose Cells code. The improvement was astonishing: Instead of the 45-minutes, the report took under a minute! I’ve pasted the client’s exact chat response after he tried the speedy Aspose version: “WWWWWOOOOOOOOWWWWWWWW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!” Microsoft’s VSTO is a free product while the Aspose components cost $$$.  Certainly, it can be a tough call when budgets are tight. If you’re trying to convince the client to shell out for something more suitable for the application, get an eval version of Aspose.Total and offer a direct comparison demo. Ken Full Disclosure: Aspose (like several other component vendors) gives free copies of their suite to MVPs and other .NET influencers.

  • Use a Free Utility to Create Multiple Virtual Desktops in Windows

    - by Lori Kaufman
    If you’ve used Linux, you’re probably familiar with the virtual desktop feature. It provides a convenient way to organize programs and folders open on your desktop. You can switch among multiple desktops and have different programs and folders open on each one. However, virtual desktops is a feature missing in Windows. There are many third-party options for adding virtual desktops to Windows, including one called Dexpot, which we have covered previously. Dexpot is free, but only for private use. Companies, public institutions, non-profit organizations, and even freelancers and self-employed people must buy the program. We found another virtual desktop tool that is completely free for everyone to use, called mDesktop. It’s a lightweight, open source program that allows you to switch among multiple desktops using hot keys and specify open programs or folders to be active on all desktops. You can use mDesktop to group related programs or to work on different projects on separate desktops. mDesktop is portable and does not need to be installed. Simply extract the .zip file you downloaded (see the link at the end of this article) and double-click the mDesktop.exe file.

  • Out of space despite lots of free space remaining

    - by Kristian Thomsen
    When upgrading Ubuntu from 11.10 to 12.04 I discovered an unexpected problem. The upgrade was stopped because there wasn't enough free space for the installation. I managed to free some space and do the upgrade but now a prompt appears after logging in saying I'm out of space. This prompt asks me if I want to examine the problem. The "Disk Usage Analyser" is opened. In the top it says: Total filesystem capacity: 47.0 GB (used: 13.5 GB available: 33.4 GB) Folder -- Usage -- Size / -- 100% -- 12.5 GB usr -- 44.8 % -- 5.6 GB home -- 30.3 % -- 3.8 GB lib -- 13.0 % -- 1.6 GB var -- 9.1 % -- 1.1 GB boot 2.5 % 309.5 GB and a lot of small contributors like: etc, opt, sbin, bin etc. I do not really understand this problem since the analyser in the top says that I have 33.4 GB left in this file system. What can I do to make Ubuntu use the remaining space? Running df -i in the terminal gives: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda7 610800 576874 33926 95% / udev 213451 563 212888 1% /dev tmpfs 218524 486 218038 1% /run none 218524 3 218521 1% /run/lock none 218524 7 218517 1% /run/shm /dev/sda8 2264752 16371 2248381 1% /home What does this mean?

  • Free Updates and Errata for Oracle Linux

    - by Lenz Grimmer
    ISO images of the Oracle Linux installation media as well as individual binary RPMs (and the sources) of major and minor releases (Updates) have always been freely available for download, use and distribution, ever since we started the Oracle Linux support program. We're now taking this a step further: in addition to the above, we will now also provide updated packages or errata for free from separate yum repositories on http://public-yum.oracle.com. If you would like to keep your Oracle Linux system up to date, you can now do so by subscribing your system to the respective "_latest" repository for your distribution, e.g. "ol6_latest" for Oracle Linux 6. See the installation instructions on the public yum front page for details on how enable these repositories. If you would like to also receive free updates to the Unbreakable Enterprise Kernel Release 2, make sure to enable the "[ol6_UEK_latest]" repository as well - updates to the kernel will be made available from this separate channel until it is included in the next set of installation media. Now what does this mean for Oracle Network Support? Getting access to the updates and errata was just one part of the offering – the following benefits will still only be available with an Oracle Linux Support Subscription only: Full indemnification against intellectual property claims. Use of base functionality in Enterprise Manager 12c for Linux and Enterprise Manager OpsCenter for provisioning, patching, management and monitoring of Oracle Linux Access to additional software channels on the Unbreakable Linux Network (ULN) (e.g. DTrace beta releases or ASM support packages) Wim also published a blog post with his take on the announcement.

  • Free NOSQL database for use with C# client [closed]

    - by Mitten
    I've never used NOSQL databases before, but so far it seems like the best data storage solution for my project. I am going to implement a datamining application. The data I would like to mine is thousands of documents which cannot be imported into datamining applications. To make to import easier and faster (than importing thousands of documents) I am planning to import these documents into a NOSQL database first and when import NOSQL database into datamining software. At the very least once I have all the data in NOSQL database I should be able to code simplest datamining logic myself. Am I correct that NOSQL databases allow to creates records of data, but they don't mandate all the records to adhere to the same data schema (same column names/types in a classic table oriended SQL databases)? I think for each document I would create a row/entry/object (not sure what is the correct term is in use in NOSQL world) which would be a string id, few (columns) with unstructured text data, and a dozens of columns mostly of datetime and integer types. From its name NOSQL does not support SQL query syntax, but it support locating the object(row/entry?) by its unique id. Does NOSQL support qyuering objects using property=value syntax? Unfortunately most of free NOSQL db only support Java/C++ clients, which free NOSQL db would you recommend for a C# programmer?

  • how to do partial updates in OpenGL?

    - by Will
    It is general wisdom that you redraw the entire viewport on each frame. I would like to use partial updates; what are the various ways can do that, and what are their pros, cons and relative performance? (Using textures, FBOs, the accumulator buffer, any kind of scissors that can affect swapbuffers etc?) A scenario: a scene with a fair few thousand visible trees; although the textures are mipmapped and they are drawn via VBOs roughly front-to-back with so on, its still a lot of polys. Would streaming a single screen-sized texture be better than throwing them at the screen every frame? You'd have to redraw and recapture them only on camera movement or as often as your wind model updates or whatever, which need not be every frame.

  • Why do programmers write closed source applications and then make them free? [closed]

    - by Ken
    As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubicle. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

  • Triple buffering causes input lag?

    - by user782220
    Consider some time in between two vsyncs. Suppose the first display buffer is being used to display the current image, and suppose the game was really fast and computed and rendered the next image to the second display buffer and the next one after that to the third display buffer. That is the rendering to the second and third display buffer happens so fast that it occurs before the next vsync. Suppose input from the user comes in now. What you would like is for the results of the input to show up on the next vsync or (probably more typical) the vsync after that. However, with the third display buffer already rendered the input can only effect the image after that. Meaning the input will only take effect at best 3 vsyncs later. I wish i had an image to show the exact timings of what I mean.

  • Is using a dedicated thread just for sending gpu commands a good idea?

    - by tigrou
    The most basic game loop is like this : while(1) { update(); draw(); swapbuffers(); } This is very simple but have a problem : some drawing commands can be blocking and cpu will wait while he could do other things (like processing next update() call). Another possible solution i have in mind would be to use two threads : one for updating and preparing commands to be sent to gpu, and one for sending these commands to the gpu : //first thread while(1) { update(); render(); // use gamestate to generate all needed triangles and commands for gpu // put them in a buffer, no command is send to gpu // two buffers will be used, see below pulse(); //signal the other thread data is ready } //second thread while(1) { wait(); // wait for second thread for data to come send_data_togpu(); // send prepared commands from buffer to graphic card swapbuffers(); } also : two buffers would be used, so one buffer could be filled with gpu commands while the other would be processed by gpu. Do you thing such a solution would be effective ? What would be advantages and disadvantages of such a solution (especially against a simpler solution (eg : single threaded with triple buffering enabled) ?

  • is Java free for mobile development?

    - by exTrace101
    Q1. I would like to know if it's free for a developer (I mean, if I have to pay no royalties to Sun/Oracle) to develop (Android) mobile apps in Java? After reading this snippet about use of Java field, I'm getting the impression that Java is not free for mobile development, is that right? .."General Purpose Desktop Computers and Servers" means computers, including desktop and laptop computers, or servers, used for general computing functions under end user control (such as but not specifically limited to email, general purpose Internet browsing, and office suite productivity tools).

  • btrfs and missing free space

    - by easteregg
    I converted my ext4 partition to btrfs and deleted the save subvolume after doing so. Then I enabled the compression (lzo) of the filessystem in the fstab file and everything is correct so far. Then I forced the compression of all files using the defragmentation command with the parameter -c that the new compression is applied to all files. While doing so, I noticed that my ssd got completly filled up - before I had 6gigs of free space. No I got nothing left. easteregg@x201s:~$ btrfs fi df / Data: total=50.00GB, used=49.17GB System: total=32.00MB, used=4.00KB Metadata: total=24.50GB, used=9.86GB and easteregg@x201s:~$ df -ha Filesystem Size Used Avail Use% Mounted on /dev/sda1 75G 60G 852M 99% / So now. How can I regain my free space. I expected to gain more space because of the lzo compression. And now! The fs is correctly mounted. easteregg@x201s:~$ mount /dev/sda1 on / type btrfs (rw,noatime,ssd,compress=lzo) Any ideas how to fix this issue?

  • Administrator's shortcut to batch file with double quoted parameters

    - by XXB
    Take an excruciatingly simple batch file: echo hi pause Save that as test.bat. Now, make a shortcut to test.bat. The shortcut runs the batch file, which prints "hi" and then waits for a keypress as expected. Now, add some argument to the target of the shortcut. Now you have a shortcut to: %path%\test.bat some args The shortcut runs the batch file as before. Now, run the shortcut as administrator. (This is on Windows 7 by the way.) You can use either right-click - Run as Administrator, or go to the shortcut's properties and check the box in the advanced section. Tell UAC that it's okay and once again the shortcut runs the batch file as expected. Now, change the arguments in the target of the shortcut to add double quotes: %path%\test.bat "some args" Now try the shortcut as administrator. It doesn't work this time! A command window pops up and and disappears too fast to see any error. I tried adding test.log 2&1 to the shortcut, but no log is created in this case. Try running the same shortcut (with the double quotes) but not as Administrator. It runs the batch file fine. So, it seems the behavior is not because of the double quoted parameters, and it's not because it's run as Administrator. It's some weird combination of the two. I also tried running the same command from an administrator's command window. This ran the batch file as expected without error. Running the shortcut from the command window spawned a new command window which flashed and went away. So apparently the issue is caused by a combination of administrator, the shortcut, and the double quotes. I'm totally stumped, does anyone have any idea what's going on?

  • Listen to double click not click

    - by Mohsen
    I'm just wondering why click event happening when I dbclick an element? I have this code:(JSBIN) HTML <p id="hello">Hello World</p> JavaScript document.getElementById('hello').addEventListener('click', function(e){ e.preventDefault(); this.style.background = 'red'; }, false); document.getElementById('hello').addEventListener('dbclick', function(){ this.style.background = 'yellow'; }, false); It should do different things for click and double click, but it seems when you double click on the p it catch click event in advance and ignore double click. I tried preventDefault the click event too. How can I listen to just dbclick? UPDATE I had a typo in my code. dbclick is wrong. It's dblclick. Anyway the problem still exist. When user double clicks the click event happens. This is updated code that prove it:(JSBin) document.getElementById('hello').addEventListener('click', function(e){ e.preventDefault(); this.style.background = 'red'; this.innerText = "Hello World clicked"; }, false); document.getElementById('hello').addEventListener('dblclick', function(){ this.style.background = 'green'; }, false);

  • Perl regex which grabs ALL double letter occurances in a line

    - by phileas fogg
    Hi all, still plugging away at teaching myself Perl. I'm trying to write some code that will count the lines of a file that contain double letters and then place parentheses around those double letters. Now what I've come up with will find the first ocurrance of double letters, but not any other ones. For instance, if the line is: Amp, James Watt, Bob Transformer, etc. These pioneers conducted many My code will render this: 19 Amp, James Wa(tt), Bob Transformer, etc. These pioneers conducted many The "19" is the count (of lines containing double letters) and it gets the "tt" of "Watt" but misses the "ee" in "pioneers". Below is my code: $file = '/path/to/file/electricity.txt'; open(FH, $file) || die "Cannot open the file\n"; my $counter=0; while (<FH>) { chomp(); if (/(\w)\1/) { $counter += 1; s/$&/\($&\)/g; print "\n\n$counter $_\n\n"; } else { print "$_\n"; } } close(FH); What am I overlooking? TIA!

  • 10 Great Free Icon Packs To Theme Your Android Phone

    - by Chris Hoffman
    Android allows you to customize your home screen, adding widgets, arranging shortcuts and folders, choosing a background, and even replacing the included launcher entirely. You can install icon packs to theme your app icons, too. Third-party launchers use standard app icons by default, but they don’t have to. You can install icon packs that third-party launchers will use in place of standard app icons. How to Use Icon Packs To use icon packs, you’ll need to use a third-party launcher that supports them, such as Nova, Apex, ADW, Go Launcher, Holo Launcher, or Action Launcher Pro. Once you’re using a third-party launcher, you can install an icon pack and go into your launcher’s settings. You’ll find an option that allows you to choose between the icon packs you’ve installed. Many of these icon packs also include wallpapers, which you can set in the normal way. MIUI 5 Icons This icon pack offers over 1900 free icons that are similar to the icons used by the MIUi ROM developed by China’s Xiaomi Tech. The large list of icons is a big plus — this pack will give the majority of your app icons a very slick, consistent look. DCikonZ Theme DCikonZ is a free icon theme that includes a whopping 4000+ icons with a consistent look. This icon theme stands out not just because it’s huge, but also for offering for going in its own direction and avoiding the super-simple, flat look many icon packs use. Holo Icons Holo Icons replaces many app icons with simple, consistent-looking that match Google’s Holo style. If you’re a fan of Android’s Holo look, give it a try. It even tweaks many of the icons from Google’s own apps to make them look more consistent. Square Icon Pack Square Icon Pack turns your icons into simple squares. Even Google Chrome becomes an orb instead of a square. This makes every icon a consistent size and offers a unique look. The icons here almost look a bit like the small-size tiles available on Windows Phone and Windows 8.1. The free version doesn’t offer as many icons as the paid version, but it does offer icons for many popular apps. Rounded Want rounded icons instead? Try the Rounded icon theme, which offers simple rounded icons. The developer says they’re inspired by the consistently round icons used on Mozilla’s Firefox OS. Crumbled Icon Pack Crumbled Icon Pack applies an effect that makes icons look as if they’r crumbling. Rather than theming individual icons, Crumbled Icon Pack adds an effect to every app icon on your device. This means that all your app icons will be themed and consistent. Dainty Icon Pack Is your Android home screen too colorful? Dainty Icon Pack offers simple, gray-on-white icons for over 1200 apps. It’d be ideal over a simple background. The contrast may be a bit low here with the gray-on-white, but it’s otherwise very slick. Simplex Icons Simplex Icons offers more contrast, with black-on-gray icons. This icon pack could simplify busy home screens, allowing photographic wallpapers to come through. Min Icon Set Min attempts to go as minimal as possible, offering simple white icons for over 570 apps. It would be ideal over a simple wallpaper with app names hidden in your launcher, offering a calming, minimal home screen. For apps it doesn’t recognize, it will enclose part of the app’s icon in a white circle. Elegance Elegance goes in another direction entirely, offering icons that incorporate more details and gradients rather than going for minimalism. Its over 1200 icons offer another good option for people who aren’t into the minimal, flat look. Icon pack designers generally have to create and include their own icons to replace icons associated with specific apps, so you’ll probably find a few of your app icons aren’t replaced with most of these themes. Of course, a standard Android phone without an icon pack doesn’t have consistent icons, either. Even if all the icons in your app drawer aren’t themed, the few app icons you have on your home screen will be if you use widely used apps.
