• Advise how to write a simple test for this javascript snippet?

  - by resting

  I'm trying to start unit testing (not using any testing frameworks) for my javascripts. Here's one example of it. var obj = {}; obj.disableBtn = function ($btn, style) { $btn.attr('disabled','disabled').addClass('disabled').removeClass(style); }; The use case is as such: obj.disableBtn($('.submit'), 'btn-blue'); What it does is simply add the disabled attribute, add the disabled class, and remove the btn-blue style. Please advise how would a typical test case look like in this case. I have a little knowledge on testing using assert(), but have no idea how to go about it when it involves verifying the result on HTML elements.

• Stupidly Simple SEO Review - Can You Really Get Your Site Ranking in Under an Hour?

  SEO has become an integral part of any Internet marketing campaign; if your site is not ranked in Google, it does not exist. However the competition is not getting any easier, and it is harder to achieve high rankings in the search engines. It's a serious thought that Google's search engine traffic is the lifeblood for so many affiliate marketers.

• What language and tools can I use to create a simple game with child-lock (capture all key press) for Windows? [closed]

  - by scw

  I'm writing an open source program that changes colors & plays sounds when keys are pressed. I want it to run in full screen mode and have a child-lock so kids can't exit accidentally. I want it to capture all keys including ctrl alt delete. (So it's partially a game, but partially windows utility.) My target OS is Windows 7 (32 & 64 bit), keeping Windows 8 in mind. My options: Visual Studio using .net C# Windows Forms - the devil I know. But not a "game" platform, which is why I'm asking this question. Visual Studio & XNA - have never used XNA, not sure of capabilities or support future Python - What flavor, what modules, what IDE? I've never done anything with Python but I found a couple of similar open source projects in python. Something else that I don't know about? Any input is appreciated.

• MySQL Query performance - huge difference in time

  - by Damo

  I have a query that is returning in vastly different amounts of time between 2 datasets. For one set (database A) it returns in a few seconds, for the other (database B)....well I haven't waited long enough yet, but over 10 minutes. I have dumped both of these databases to my local machine where I can reproduce the issue running MySQL 5.1.37. Curiously, database B is smaller than database A. A stripped down version of the query that reproduces the problem is: SELECT * FROM po_shipment ps JOIN po_shipment_item psi USING (ship_id) JOIN po_alloc pa ON ps.ship_id = pa.ship_id AND pa.UID_items = psi.UID_items JOIN po_header ph ON pa.hdr_id = ph.hdr_id LEFT JOIN EVENT_TABLE ev0 ON ev0.TABLE_ID1 = ps.ship_id AND ev0.EVENT_TYPE = 'MAS0' LEFT JOIN EVENT_TABLE ev1 ON ev1.TABLE_ID1 = ps.ship_id AND ev1.EVENT_TYPE = 'MAS1' LEFT JOIN EVENT_TABLE ev2 ON ev2.TABLE_ID1 = ps.ship_id AND ev2.EVENT_TYPE = 'MAS2' LEFT JOIN EVENT_TABLE ev3 ON ev3.TABLE_ID1 = ps.ship_id AND ev3.EVENT_TYPE = 'MAS3' LEFT JOIN EVENT_TABLE ev4 ON ev4.TABLE_ID1 = ps.ship_id AND ev4.EVENT_TYPE = 'MAS4' LEFT JOIN EVENT_TABLE ev5 ON ev5.TABLE_ID1 = ps.ship_id AND ev5.EVENT_TYPE = 'MAS5' WHERE ps.eta >= '2010-03-22' GROUP BY ps.ship_id LIMIT 100; The EXPLAIN query plan for the first database (A) that returns in ~2 seconds is: +----+-------------+-------+--------+----------------------------------------------------------------------------------------------------------------------------------------+----------------------------------+---------+------------------------------+------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+----------------------------------------------------------------------------------------------------------------------------------------+----------------------------------+---------+------------------------------+------+----------------------------------------------+ | 1 | SIMPLE | ps | range | PRIMARY,IX_ETA_DATE | IX_ETA_DATE | 4 | NULL | 174 | Using where;

Database A also has this state but for only a second or so. There are no differences in the table structure, indexes, keys etc between these databases (I have done show create tables and diff'd them). The sizes of the tables are: database A: po_shipment 1776 po_shipment_item 1945 po_alloc 36298 po_header 71642 EVENT_TABLE 1608 database B: po_shipment 463 po_shipment_item 470 po_alloc 3291 po_header 56149 EVENT_TABLE 1089 Some points to note: Removing the WHERE clause makes the query return < 1 sec. Removing the GROUP BY makes the query return < 1 sec. Removing ev5, ev4, ev3 etc makes the query get faster for each one removed. Can anyone suggest how to resolve this issue? What have I missed? Many Thanks.

• When is factory method better than simple factory and vice versa?

  - by Bruce

  Hi all Working my way through the Head First Design Patterns book. I believe I understand the simple factory and the factory method, but I'm having trouble seeing what advantages factory method brings over simple factory. If an object A uses a simple factory to create its B objects, then clients can create it like this: A a = new A(new BFactory()); whereas if an object uses a factory method, a client can create it like this: A a = new ConcreteA(); // ConcreteA contains a method for instantiating the same Bs that the BFactory above creates, with the method hardwired into the subclass of A, ConcreteA. So in the case of the simple factory, clients compose A with a B factory, whereas with the factory method, the client chooses the appropriate subclass for the types of B it wants. There really doesn't seem to be much to choose between them. Either you have to choose which BFactory you want to compose A with, or you have to choose the right subclass of A to give you the Bs. Under what circumstances is one better than the other? Thanks all!

• How do I show some simple HTML (text/images) in the sidebar of my Drupal 7 theme?

  - by shady

  I've created a theme using Zen and all is well. I want to display some simple text and images in the sidebar, but I don't understand Drupal well enough to know what I'm doing. I have worked with Joomla which allows one to create a new HTML module, populate it, and then select where it appears on the page (and also of course which pages). I don't see this with Drupal. I've seen some talk about using the theme's templates, but I need for my client to be able to change the text (and/or images) without knowing anything about that. It would be best to create an article and be able to make that article appear in the side bar somehow. Is this possible?

• Android app works on emulator but not on phone ("Can't dispatch DDM chunk XXXX: no handler defined")

  Hey all, I made a very simple application to start playing around with Android development. It works fine on the emulator, but it gives me the following error when I try to install it on my HTC Hero (v1.5): Sorry!

• A simple free MIDI implementation in Java besides javax.sound.midi: Are there any?

  - by Peterdk

  The problem is: Android doesn't implement javax.sound.midi. I need a simple free library that allows me to create simple 1-track midi files. I searched the net for it, but can't really find anything, since everything uses javax.sound.midi . The license needs to be one where I don't need to opensource my linked app. Any ideas? I also looked into the fileformat itself. However, I am totally not familiar with working with bytes, hexidecimal stuff etc. So, other option is: are there any simple midi implementations that I can use as reference?

• PHP or Javascript or other - Draw simple shapes onto images?

  - by Tommo

  I basically have an image of a world map and i would like to place a pin image at a specified pixel co-ordinate ontop of this world map image. It's for a website, so ideally the solution should be in PHP or Javascript (i'm avoiding Java and Flash as i want it to be as simple as possible). I had a look at the processing.js library but it is way to big and bloated for just performing this simple task. Is there a pre-existing Javascript function which will allow me to do this? Or a more simple javascript library that i can use? (processing.js was a bit too advanced for me, i couldnt get it working lol) In terms of a PHP solution, i would prefer taking the load off the server and onto the client for this task, but i would still like to hear methods for doing it in PHP if they are suitable. Thanks!

• Are your personal insecurities screwing up your internal communications?

  - by Lucy Boyes

  I do some internal comms as part of my job. Quite a lot of it involves talking to people about stuff. I’m spending the next couple of weeks talking to lots of people about internal comms itself, because we haven’t done a lot of audience/user feedback gathering, and it turns out that if you talk to people about how they feel and what they think, you get some pretty interesting insights (and an idea of what to do next that isn’t just based on guesswork and generalising from self). Three things keep coming up from talking to people about what we suck at  in terms of internal comms. And, as far as I can tell, they’re all examples where personal insecurity on the part of the person doing the communicating makes the experience much worse for the people on the receiving end. 1. Spending time telling people how you’re going to do something, not what you’re doing and why Imagine you’ve got to give an update to a lot of people who don’t work in your area or department but do have an interest in what you’re doing (either because they want to know because they’re curious or because they need to know because it’s going to affect their work too). You don’t want to look bad at your job. You want to make them think you’ve got it covered – ideally because you do*. And you want to reassure them that there’s lots of exciting work going on in your area to make [insert thing of choice] happen to [insert thing of choice] so that [insert group of people] will be happy. That’s great! You’re doing a good job and you want to tell people about it. This is good comms stuff right here. However, you’re slightly afraid you might secretly be stupid or lazy or incompetent. And you’re exponentially more afraid that the people you’re talking to might think you’re stupid or lazy or incompetent. Or pointless. Or not-adding-value. Or whatever the thing that’s the worst possible thing to be in your company is. So you open by mentioning all the stuff you’re going to do, spending five minutes or so making sure that everyone knows that you’re DOING lots of STUFF. And the you talk for the rest of the time about HOW you’re going to do the stuff, because that way everyone will know that you’ve thought about this really hard and done tons of planning and had lots of great ideas about process and that you’ve got this one down. That’s the stuff you’ve got to say, right? To prove you’re not fundamentally worthless as a human being? Well, maybe. But probably not. See, the people who need to know how you’re going to do the stuff are the people doing the stuff. And those are the people in your area who you’ve (hopefully-please-for-the-love-of-everything-holy) already talked to in depth about how you’re going to do the thing (because else how could they help do it?). They are the only people who need to know the how**. It’s the difference between strategy and tactics. The people outside of your bubble of stuff-doing need to know the strategy – what it is that you’re doing, why, where you’re going with it, etc. The people on the ground with you need the strategy and the tactics, because else they won’t know how to do the stuff. But the outside people don’t really need the tactics at all. Don’t bother with the how unless your audience needs it. They probably don’t. It might make you feel better about yourself, but it’s much more likely that Bob and Jane are thinking about how long this meeting has gone on for already than how personally impressive and definitely-not-an-idiot you are for knowing how you’re going to do some work. Feeling marginally better about yourself (but, let’s face it, still insecure as heck) is not worth the cost, which in this case is the alienation of your audience. 2. Talking for too long about stuff This is kinda the same problem as the previous problem, only much less specific, and I’ve more or less covered why it’s bad already. Basic motivation: to make people think you’re not an idiot. What you do: talk for a very long time about what you’re doing so as to make it sound like you know what you’re doing and lots about it. What your audience wants: the shortest meaningful update. Some of this is a kill your darlings problem – the stuff you’re doing that seems really nifty to you seems really nifty to you, and thus you want to share it with everyone to show that you’re a smart person who thinks up nifty things to do. The downside to this is that it’s mostly only interesting to you – if other people don’t need to know, they likely also don’t care. Think about how you feel when someone is talking a lot to you about a lot of stuff that they’re doing which is at best tangentially interesting and/or relevant. You’re probably not thinking that they’re really smart and clearly know what they’re doing (unless they’re talking a lot and being really engaging about it, which is not the same as talking a lot). You’re probably thinking about something totally unrelated to the thing they’re talking about. Or the fact that you’re bored. You might even – and this is the opposite of what they’re hoping to achieve by talking a lot about stuff – be thinking they’re kind of an idiot. There’s another huge advantage to paring down what you’re trying to say to the barest possible points – it clarifies your thinking. The lightning talk format, as well as other formats which limit the time and/or number of slides you have to say a thing, are really good for doing this. It’s incredibly likely that your audience in this case (the people who need to know some things about your thing but not all the things about your thing) will get everything they need to know from five minutes of you talking about it, especially if trying to condense ALL THE THINGS into a five-minute talk has helped you get clear in your own mind what you’re doing, what you’re trying to say about what you’re doing and why you’re doing it. The bonus of this is that by being clear in your thoughts and in what you say, and in not taking up lots of people’s time to tell them stuff they don’t really need to know, you actually come across as much, much smarter than the person who talks for half an hour or more about things that are semi-relevant at best. 3. Waiting until you’ve got every detail sorted before announcing a big change to the people affected by it This is the worst crime on the list. It’s also human nature. Announcing uncertainty – that something important is going to happen (big reorganisation, product getting canned, etc.) but you’re not quite sure what or when or how yet – is scary. There are risks to it. Uncertainty makes people anxious. It might even paralyse them. You can’t run a business while you’re figuring out what to do if you’ve paralysed everyone with fear over what the future might bring. And you’re scared that they might think you’re not the right person to be in charge of [thing] if you don’t even know what you’re doing with it. Best not to say anything until you know exactly what’s going to happen and you can reassure them all, right? Nope. The people who are going to be affected by whatever it is that you don’t quite know all the details of yet aren’t stupid***. You wouldn’t have hired them if they were. They know something’s up because you’ve got your guilty face on and you keep pulling people into meeting rooms and looking vaguely worried. Here’s the deal: it’s a lot less stressful for everyone (including you) if you’re up front from the beginning. We took this approach during a recent company-wide reorganisation and got really positive feedback. People would much, much rather be told that something is going to happen but you’re not entirely sure what it is yet than have you wait until it’s all fixed up and then fait accompli the heck out of them. They will tell you this themselves if you ask them. And here’s why: by waiting until you know exactly what’s going on to communicate, you remove any agency that the people that the thing is going to happen to might otherwise have had. I know you’re scared that they might get scared – and that’s natural and kind of admirable – but it’s also patronising and infantilising. Ask someone whether they’d rather work on a project which has an openly uncertain future from the beginning, or one where everything’s great until it gets shut down with no forewarning, and very few people are going to tell you they’d prefer the latter. Uncertainty is humanising. It’s you admitting that you don’t have all the answers, which is great, because no one does. It allows you to be consultative – you can actually ask other people what they think and how they feel and what they’d like to do and what they think you should do, and they’ll thank you for it and feel listened to and respected as people and colleagues. Which is a really good reason to start talking to them about what’s going on as soon as you know something’s going on yourself. All of the above assumes you actually care about talking to the people who work with you and for you, and that you’d like to do the right thing by them. If that’s not the case, you can cheerfully disregard the advice here, but if it is, you might want to think about the ways above – and the inevitable countless other ways – that making internal communication about you and not about your audience could actually be doing the people you’re trying to communicate with a huge disservice. So take a deep breath and talk. For five minutes or so. About the important things. Not the other things. As soon as you possibly can. And you’ll be fine.   *Of course you do. You’re good at your job. Don’t worry. **This might not always be true, but it is most of the time. Other people who need to know the how will either be people who you’ve already identified as needing-to-know and thus part of the same set as the people in you’re area you’ve already discussed this with, or else they’ll ask you. But don’t bring this stuff up unless someone asks for it, because most of the people in the audience really don’t care and you’re wasting their time. ***I mean, they might be. But let’s give them the benefit of the doubt and assume they’re not.

• How do I identify and fix the cause of transaction log growth on SIMPLE recovery model databases?

  - by Stuart B

  I recently upgraded our SQL Server 2008 installations to service pack 2. One of our databases is on the simple recovery model, but its transaction log is growing extremely fast. The path I'm currently investigating is that we have a transaction somewhere out there stuck in active state. Here is why: select name, recovery_model_desc, log_reuse_wait_desc from sys.databases where name in ('SimpleDB') name recovery_model_desc log_reuse_wait_desc SimpleDB SIMPLE ACTIVE_TRANSACTION When I check my active transactions, I get the following. Note that I installed SP2 and restarted our server on 12/25 at around noonish. select transaction_id, name, transaction_begin_time, transaction_type from sys.dm_tran_active_transactions transaction_id name transaction_begin_time transaction_type 233 worktable 2010-12-25 12:44:29.283 2 236 worktable 2010-12-25 12:44:29.283 2 238 worktable 2010-12-25 12:44:29.283 2 240 worktable 2010-12-25 12:44:29.283 2 243 worktable 2010-12-25 12:44:29.283 2 245 worktable 2010-12-25 12:44:29.283 2 62210 tran_sp_MScreate_peer_tables 2010-12-25 12:45:00.880 1 55422856 user_transaction 2010-12-28 16:41:56.703 1 55422889 SELECT 2010-12-28 16:41:57.303 2 470 LobStorageProviderSession 2010-12-25 12:44:30.510 2 Note that according to the documentation a transaction_type of 1 means read/write, and 2 means read-only. So, my line of thinking is that the trans_sp_MScreate_peer_tables transaction is stuck for some reason and holding up transaction log truncation. Is this a plausible scenario? Correct me if my line of thinking is off, as I'm not a SQL Server expert. If this is correct, how do I erase that transaction so that my transaction log is truncated as usual?

• How use DNS server to create simple HA (High availability) of my website?

  - by marc22

  Welcome, How can i use DNS server to create simple HA (High availability) of website ? For example if my web-server ( for better understanding i use internal IP in real it will be other hosting companies) 192.168.0.120 :80 (is offline) traffic go to 192.168.0.130 :80 You have right, i use bad word "hight avability" of course i was thinking about failover. Using few IP in A records is good for simple load-balancing. But not in case, if i want notice user about failure (for example display page, Oops something is wrong without our server, we working on it) against "can't establish connection". I was thinking about setting up something like this 2 DNS servers, one installed on www server Both have low TTL on my domain, set up 2 ns records first for DNS with my apache server second to other dns If user try connect he will get ip of www server using first dns, if that dns is offline (probably www server is also down) so it will try second NS record, what will point to another dns, that dns will point to "backup" page. That's what i would like to do. If You have other idea please share. Reverse proxy is not option, because IP of server can change, or i can use other country for backup.

• What is a suitable simple, open web server for Windows?

  - by alficles

  I'm looking for a dead simple web server for Windows. Load will not be high as it will be primarily serving binaries for a WPKG update service. It needs to serve the entire contents of a single folder over HTTP on a configurable (high) port. No CGI or other scripting is required, but it might be nice for future features. I started with Mongoose, since it doesn't even have an installation requirement (a very nice perk), but it fails to start when run as a service. (Technically, it acts as it's own installer.) I've investigated LighTPD as well, but it appears to be minimally (at best) tested on Windows. And naturally, I'm looking for something free. As in beer is good, but speech is better, as always. Edit: I didn't mention this initially, but non-tech people will be doing the install. They'll have whatever script I write for the install, but the goal is a simple system that is easy to troubleshoot. (I almost worded this question "What is the best...", but Serverfault rightly observed that that is a subjective question. And it's really not an optimization problem, any suitable solution will work. I just can't seem to find one for Windows.)

• Recommendation for a simple no-frills Windows PDF printer driver?

  - by Scott Bussinger

  I'm looking for an extremely simple Windows PDF printer driver that I can recommend to clients. Ideally it would have these characteristics: When you print something, it should just create it as a temporary file and then display it in their default PDF viewer with no prompting. If they want to save it, they can save it manually from inside the viewer. This workflow should be with no special post-install configuration. Installation should be very simple. A double click the installation program and click "Finish" sort of thing. No complicated multi-step installation, no asking questions your grandmother wouldn't know the answer to (preferably no questions at all), no extra crap being installed. An option for a completely silent installation would be nice, but not necessary. Ideally it would be free to simplify their installing on a small network, but low cost is an option. I've tried a quite a few but none really fit the bill. Some can achieve the first goal but only after careful configuration, some try to install extra toolbars, some have other installation complexities that would make it hard for extremely novice users to succeed. Any suggestions? Thanks!

• Monitoring the Application alongside SQL Server

  - by Tony Davis

  Sometimes, on Simple-Talk, it takes a while to spot strange and unexpected patterns of user activity, or small bugs. For example, one morning we spotted that an article’s comment count had leapt to 1485, but that only four were displayed. With some rooting around in Google Analytics, and the endlessly annoying Community Server admin-interface, we were able to work out that a few days previously the article had been subject to a spam attack and that the comment count was for some reason including both accepted and unaccepted comments (which in turn uncovered a bug in the SQL). This sort of incident made us a lot keener on monitoring Simple-talk website usage more effectively. However, the metrics we wanted are troublesome, because they are far too specific for Google Analytics to measure, and the SQL Server backend doesn’t keep sufficient information to enable us to plot trends. The latter could provide, for example, the total number of comments made on, or votes cast for, articles, over all time, but not the number that occur by hour over a set time. We lacked a baseline, in other words. We couldn’t alter the database, as it is a bought-in package. We had neither the resources nor inclination to build-in dedicated application monitoring. Possibly, we could investigate a third-party tool to do the job; but then it occurred to us that we were already using a monitoring tool (SQL Monitor) to keep an eye on the database. It stored data, made graphs and sent alerts. Could we get it to monitor some aspects of the application as well? Of course, SQL Monitor’s single purpose is to check and monitor SQL Server, over time, rather than to monitor applications that use SQL Server. However, how different is the business of gathering and plotting SQL Server Wait Stats, from gathering and plotting various aspects of user activity on the site? Not a lot, it turns out. The latest version allows us to write our own custom monitoring scripts, meaning that we could now monitor any metric in the application that returns an integer. It took little time to write a simple SQL Query that collects basic metrics of the total number of subscribers, votes cast, comments made, or views of articles, over time. The SQL Monitor database polls Simple-Talk every second or so in order to get the latest totals, and can then store and plot this information, or even correlate SQL Server usage to application usage. You can see the live data by visiting monitor.red-gate.com. Click the "Analysis" tab, and select one of the "Simple-talk:" entries in the "Show" box and an appropriate data range (e.g. last 30 days). It’s nascent, and we’re still working on it, but it’s already given us more confidence that we’ll spot quickly trends, bugs, or bursts of ‘abnormal’ activity. If there is a sudden rise in comments, we get an alert, and if it’s due to a spam attack, we can moderate or ban the perpetrator very quickly. We’ve often argued that a tool should perform a single job well rather than turn into a Swiss-army knife, but ironically we’ve rather appreciated being able to make best use of what’s there anyway for a slightly different purpose. Is this a good or common practice? What do you think? Cheers, Tony.

• How can I print from my lion mac mini to my windows XP, with simple file sharing?

  - by Jules

  I have quite a complicated setup, perhaps. And a lot of history on this issue, I'm hoping that I don't have to buy a new printer. I've got a HP Wireless USB Print Server, which requires client software, I can't just use it as an IP Printer. The HP software is pretty poor on the mac and is no longer supported and often locks up the printer server and takes some considerable effort to actually print something. Let alone if a windows machine attaches to it first. My printer is an Epson Stylus R285. However, the windows client software is fine and we can print from windows 7 / XP without problem. We have simple file sharing setup as this is the only way I could get windows XP to talk to windows 7. However, I can't seem to get my mac mini to connect as anything other than a guest to my xp machine, to connect to the shared printer. I'm not considering some kind of internet printing as this would seems the simplest solution. But I'm not sure what will work with my setup ?

• Does anyone know of a simple way to get an 8CH ADAT signal into a laptop/desktop?

  - by Corey

  The only interfaces I can find with ADAT cost more than I am willing to spend, and have a lot of features and inputs that I do not need. Ideally this would be a simple USB/FIREWIRE/PCI device with 1 ADAT input and output. Support for at least WinXP would be a must. Somthing in the $0-100 range.

• Any simple tools for re-loading a specified web page periodically (Windows)?

  - by Luke

  I've got a website that is exhibiting slow performance on the first load and would like to attempt to load it every 5 minutes or so to keep the cache fresh. Are there any simple tools to accomplish this? Scheduled tasks doesn't have quite the time resolution I need. The tricky thing is that this site uses Windows authentication so a wget script won't work. I'm also worried about instantiating a bunch of copies of internet explorer or attempting to kill iexplore.exe tasks blindly.

• Can I get simple name resolution on the local network without DNS, on a Mac?

  - by tim

  I've got Mantis running on a Linux VM with a Win2k8 server host. I installed Samba with the following configuration: [global] workgroup = COMPANY netbios name = MANTIS security = share Now on all our windows machines people can simple go to http://mantis, rather than http://172.16.0.20. However, this doesn't appear to work on the Mac machines. Any ideas how I can sort this without changing anything on the Windows server?

• Is there a simple way to detect ISP port blocking?

  - by Will M

  Is there a way to tell the difference between my ISP blocking traffic on certain ports and my NAT router/firewall blocking that traffic? The sites “Shields Up” and “Can you see me” show my ports closed or not accessible, but I assume that is primarily due to the NAT router. (Obviously, I could just remove the router, connect directly and use those sites, but is there a simple way to test without doing that?)

• What are the alternative simple softwares for MS Paint?

  - by hkBattousai

  MS Paint is good but it lacks quality on some of its tools. I want to try its alternative software. Can you please give me a list of its alternatives. I'm looking for simple software as MS Paint is. Please don't suggest me complicated software like Gimp and Photoshop. I have already tried Paint.NET, but it is too dependent on Microsoft .NET Framework, so it is very problematic to install in the first place.
