  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • T-SQL Tuesday # 16 : This is not the aggregate you're looking for

    - by AaronBertrand
    This week, T-SQL Tuesday is being hosted by Jes Borland ( blog | twitter ), and the theme is " Aggregate Functions ." When people think of aggregates, they tend to think of MAX(), SUM() and COUNT(). And occasionally, less common functions such as AVG() and STDEV(). I thought I would write a quick post about a different type of aggregate: string concatenation. Even going back to my classic ASP days, one of the more common questions out in the community has been, "how do I turn a column into a comma-separated...(read more)

  • How to Install & Use the Window Maker Desktop Environment on Ubuntu

    - by Chris Hoffman
    Window Maker is a Linux desktop environment designed to emulate NeXTSTEP, which eventually evolved into Mac OS X. With its focus on emulating NeXTSTEP, it eschews the task bars and application menu buttons found in many other lightweight desktop environments. Window Maker is now under active development again after seven years without an official release. A lot has changed on the Linux desktop front since Window Maker was last being actively developed, but Window Maker still provides a unique, minimal environment – for users looking for that sort of thing.

  • Detecting End of Animation

    - by Will
    So I am making a death animation for a game. enemy1 is a UIImageView, and what I'm doing is when an integer is less than or equal to zero, it calls this deathAnimation which only happens once. What I want to do is use a CGPointMake right when the animation is finished being called. Note that before the deathAnimation is called, there is another animation that is constantly being called 30 times a second. I'm not using anything like cocos2d. if (enemy1health <= 0) { [self slime1DeathAnimation]; //How can i detect the end of this animation } This is how the animation is done -(void)slime1DeathAnimation{ enemy1.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Slime Death 1.png"], [UIImage imageNamed:@"Slime Death 2.png"], [UIImage imageNamed:@"Slime Death 3.png"], [UIImage imageNamed:@"Slime Death 4.png"], [UIImage imageNamed:@"Slime Death 5.png"], nil]; enemy1.animationDuration = 0.5; enemy1.animationRepeatCount = 1; [enemy1 startAnimating]; } If you need more code just ask

  • web server response code 500

    - by Bryan Kemp
    I realize that this may spur a religious discussion, but I discussed this with friends and get great, but conflicting answers and the actual documentation is of little help. What does the 500 series response codes mean from the webserver? Internal Server Error, but that is vague. My assumption is that it means that something bad happened to the server (file system corruption, no connection to the database, network issue, etc.) but not specifically a data driven error (divide by zero, record missing, bad parameter, etc). Something to note, there are some web client implementations (the default Android and Blackberry httpclients) that do not allow access to the html boddy if the server response is 500 so there is no way to determine what caused the issue from the client. What I have been been implementing recently is a web service that returns a json payload wrapped in a response object that contains more specific error information if it is data related, but the server response will be 200 since it finished the actual processing. Thoughts?

  • Cocos2D 2.0 - masking a sprite

    - by Desperate Developer
    I have read this tutorial about how to mask sprites using Cocos2D 2.0. http://www.raywenderlich.com/4428/how-to-mask-a-sprite-with-cocos2d-2-0 But the author talks about OpenGL ES textures and vertices as they were common knowledge. My knowledge about OpenGl is zero raised to infinity. All I want is to use a rectangle to mask a sprite to it. How I would do in Photoshop using a rectangle as mask (yes, I want to clip a sprite to the rectangle bounds and no, I do not want to use the ClippingNode solution, that do not works for animation/scaling etc.). So, can you guys translate the klingon language used in this tutorial and tell how a solid rectangle can be used to mask a sprite in Cocos2D? I am desperate, as my username states. I am searching this for a week and have tried several solutions without satisfactory results. Please help me. Thanks!

  • Platform Builder: Disable the USB Driver Dialog

    - by Bruce Eitman
    For a long time, Windows CE developers and users have wanted to disable the USB Driver Dialog that is displayed when an unknown USB device is plugged into the host controller.   Of course the question is always why would you want to do such a thing? The simple answer is that there are USB devices that are needed, like printers, which expose multiple functions to the bus, like scanners and faxes, which no Windows CE driver exists to support.   So the printer quietly loads a driver, but then the other functions cause a dialog to be shown. One solution is to create a USB Class driver that loads by default if no other driver has been loaded. This driver just accepts anything that it sees and then does nothing with it. Starting with the Windows Embedded CE 6.0 R3 March QFE/update, the USB 2.0 driver has a registry value to disable the dialog: [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients]       "DoNotPromptUser"=dword:0   Setting the DoNotPromptUser value to 1 disables the dialog. The default value is zero, so the driver continues to behave in the same way it always did unless you change this registry value.     Copyright © 2010 – Bruce Eitman All Rights Reserved

  • Server Systems for SQL Server 2012 per core licensing

    - by jchang
    Until recently, the SQL Server Enterprise Edition per processor (socket) licensing model resulted in only 2 or 3 server system configurations being the preferred choice. Determine the number of sockets: 2, 4 or 8. Then select the processor with the most compute capability at that socket count level. Finally, fill the DIMM sockets with the largest capacity ECC memory module at reasonable cost per GB. Currently this is the 16GB DIMM with a price of $365 on the Dell website, and $240 from Crucial.

  • What You Said: Your Tech Spring Cleaning Routines

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tech spring cleaning routine; now we’re back to highlight your tips, tricks, and techniques. What tools rule the spring cleaning roost? Compressed air and microfiber cloths are the tools of choice by a wide margin. D^Angelo highlights the software and physicals tools he uses: Backup all the important stuff just to be safe (c:/, my documents, desktop, drivers) Cleaning the dust with some office depot compressed air, avoiding spinning the fans. Use a brush for that small places (fans, memory, capacitors, etc). Use some dielectric spray on the motherboard. If the pc turned on without problems its time to use ccleaner, Check if there is a toolbar installed or another unusual software that I don’t want. Run my antivirus software or malwarebytes; some defraggler maybe.

  • Expensive HDMI Cables Make No Difference

    - by Jason Fitzpatrick
    While we’re no strangers to spreading the news that expensive HDMI cables are a ripoff, we’re happy to share yet another study that shows there’s zero difference between a $5 cable and a $95 one. Over at the British hardware review site Expert Reviews, they subjected a wide selection of HDMI cables to extensive tests in a bid to produce the end-all examination of whether or not a premium HDMI cable could actually produce a better signal. They used capture cards, pixel-by-pixel comparison of output, and other techniques to pick over individual frames until they ultimately reached the same conclusion everyone outside of the Monster sales staff had already reached: you’re getting absolutely no benefit to spending $100 on cable that can be had for under five bucks.

  • Reinventing the Paged IEnumerable, Weigert Style!

    - by adweigert
    I am pretty sure someone else has done this, I've seen variations as PagedList<T>, but this is my style of a paged IEnumerable collection. I just store a reference to the collection and generate the paged data when the enumerator is needed, so you could technically add to a list that I'm referencing and the properties and results would be adjusted accordingly. I don't mind reinventing the wheel when I can add some of my own personal flare ... // Extension method for easy use public static PagedEnumerable AsPaged(this IEnumerable collection, int currentPage = 1, int pageSize = 0) { Contract.Requires(collection != null); Contract.Assume(currentPage >= 1); Contract.Assume(pageSize >= 0); return new PagedEnumerable(collection, currentPage, pageSize); } public class PagedEnumerable : IEnumerable { public PagedEnumerable(IEnumerable collection, int currentPage = 1, int pageSize = 0) { Contract.Requires(collection != null); Contract.Assume(currentPage >= 1); Contract.Assume(pageSize >= 0); this.collection = collection; this.PageSize = pageSize; this.CurrentPage = currentPage; } IEnumerable collection; int currentPage; public int CurrentPage { get { if (this.currentPage > this.TotalPages) { return this.TotalPages; } return this.currentPage; } set { if (value < 1) { this.currentPage = 1; } else if (value > this.TotalPages) { this.currentPage = this.TotalPages; } else { this.currentPage = value; } } } int pageSize; public int PageSize { get { if (this.pageSize == 0) { return this.collection.Count(); } return this.pageSize; } set { this.pageSize = (value < 0) ? 0 : value; } } public int TotalPages { get { return (int)Math.Ceiling(this.collection.Count() / (double)this.PageSize); } } public IEnumerator GetEnumerator() { var pageSize = this.PageSize; var currentPage = this.CurrentPage; var startCount = (currentPage - 1) * pageSize; return this.collection.Skip(startCount).Take(pageSize).GetEnumerator(); } IEnumerator IEnumerable.GetEnumerator() { return this.GetEnumerator(); } }

  • How can I get data off of a (probably) very corrupt drive?

    - by Mercury1964
    So, my younger brother wanted my help today. Apparently, he was helping a friend install Ubuntu to his laptop, and midway through the install (on a filled hard-drive with Windows 8, from the liveusb thing): 1) They realized that they had chosen "Erase and install" accidentally and decided the best course of action was to (in the middle of an install, remember) 2) Force shutdown the computer. After I had replaced my eyeballs back into their sockets, my bro asked if I could do anything about his friend's data, which he wanted back. This, however, drifts out of my normal comfort zone. I know this about the install: 1) It was on a fairly new Windows 8 laptop, so it had whatever filesystem it uses nowadays on the entire drive 2) They didn't choose the "zero out drive data" option 3) They stopped the install at some point (not sure if before or after wipe) I can imagine that it now has two corrupted filesystems on it (whatever Windows 8 was on and ext3) and that some of the data still exists (assuming it wasn't overwritten already). Is there anything that can be done for whatever data is left on the drive?

  • Is there an open source license for this?

    - by Philip
    I have written code at home, on my own time and using my own knowledge and equipment, while under no contract or NDA. I want to make this code open source so that I can use it in software I write for an employer, without denying myself the right to use it at home or elsewhere later. I'm not sure if saying it is in the "public domain" would fit this purpose, or if I need to find an open source license. I want anyone to be able to use the code in closed source proprietary software with zero requirements for including a license with the source or binary. And I want to minimize the risk of anyone being sued for using it. (I'm aware that one can never be 100% safe from being sued.) Is there an open source license that fits this purpose? To what extent is what I want to do even possible? I wouldn't mind putting the license in comments in the code files themselves, but that obviously doesn't go with the binary.

  • SQL SERVER – What is SSAS Tabular Data model and Why to use it – Part 2

    - by Pinal Dave
    In my last article, I talked about the basics of tabular data model and why use it. Then I demonstrated step by step creation of a basic tabular model project. In this part I’m going to throw some light on how to create measures and analyses in excel. If you look at the tabular project closely, you will notice that we have not defined any measure yet. So, in the first step we will define the measure first.  Open the solution and select the column you want to define as a measure. Then, click on the summation icon on the toolbar. You will see the aggregated results at the bottom of that column. You have also other choices as well like average, min, max, count and distinct count. After creating the required measures, we need to analyze our data in excel. To do this, click on the excel icon in the upper left corner of the toolbar. This will open your analysis in excel. Notice the pivot table field list here. I have highlighted the measures that we created in the earlier step. Now, we can use these measures in our analysis Now, we have to put the required fields in their respective places as column labels, row labels, Values and Report filter for analysis. See below snapshot for details, it shows region wise sales on a yearly basis You can even apply filters on the above analysis by placing the slicer field in report filter. In our example, we will take an English product name as a filter. You can use the filter as depicted in the below snapshot. Optionally, you can also use the slider to filter data more interactively. Further to improve our analysis, we can insert pivot charts That’s all for this time, in my next post I’m going to show in detail about how to create hierarchies, perspectives, KPI’s  and many more features.

  • How to use Fixedsys in the Gnome Terminal, or wherever monospaced fonts are required

    - by Walter Tross
    I think that the Fixedsys font is one of the most readable monospaced fonts for programming. It has zero antialiasing, with vertical lines mostly 2 pixels wide. Close to ideal for current monitor dot pitches, in my eyes (literally). After years of Windows at home (for family reasons) and Linux servers at work accessed through Cygwin on Windows (for company policy reasons), with Fixedsys as the shell and IDE font, I have decided to switch to the Ubuntu desktop. Eclipse and gedit are no problem, they accept the Fixedsys Excelsior TTF font. But the Gnome Terminal only accepts monospaced fonts. Although Fixedsys Excelsior is essentially monospaced, it contains larger glyphs (mostly for eastern languages), and also some ligatures. Since apparently ALL characters must have the same width for a font to be recognized as monospaced, Fixedsys Excelsior cannot be selected in all those contexts where monospaced fonts are required, including gnome-terminal. So what is the easiest/cleanest way to use a Fixedsys clone font in contexts that only accept monospaced fonts?

  • Need Help Changing Owner of External HArd Drive

    - by Thomas Ballew
    My understanding of code is about zero. I can open a terminal window, and type commands that are given to me, but that's about it. If someone can help me with this question, and explain at a level I'm likely to understand, thanks. If not, thanks anyway. I have an external hard drive with two partitions. I bought this drive when my operating system was Apple, 10.5 or so, and it was formatted as HFS+ with that system. Now, connecting the HD to my Linux system, I can read files, but I have about 1.5 TB of space that I can't use, because I am not the owner of the file, so can't write to the HD. Short of reformatting the HD, is there a way for me to set the permissions for the HD so I can write to it? Again, thank you.
