• What difference with Android when iOS is not open?

  - by hqt

  My question may seem silly, but, I've read in many Android books that the better part of Android is Android is open, and iOS is closed. But, from a programmer viewpoint, who cares about this point? Programmers just care about the platform: is it easy to program in, easy to have help in the network, etc. They don't care about whether the platform is open or closed. One book had additional information, but I don't understand it much. Since iOS is not open, I’d be able to share my work with others only if Apple allowed it. So, if you write an app, and need to share, you must have Apple's permission, but not Android's? Please help me understand this point. I'm preparing for a presentation on Android. And I don't know if I should put this point into my presentation.

• What are the pre-requisites for writing .NET web services?

  - by wackytacky99

  I am very new to web development. I have been a C,C++ programmer for 5 years and I'm starting to get into the web development, writing web services, etc. I understand that basic concepts of web services. I know .Net web services can be written in VB or C#. Working with C,C++ will help getting used to writing code in C#. I do not have experience in .Net framework. I'd like to quickly get into writing .Net web services and learning on the go, without extensively spending a lot of time learning .Net framework (if possible) Any suggestions? Update - I know my way around databases and sql express in Visual Studio

• English to French translation of computing terminology

  - by Rich

  I work in France as a Java programmer, mainly in French, but am a native English speaker. My level of French is pretty good (French wife!), but one thing I have problems with is working out whether to use English terminology or a French equivalent. Examples: lock (as in a synchronisation lock) - do I use the verb "locker" or do I use verrouiller? shard (databases) - "un shard" or "un tesson" (which means a shard of glass) ...and so-on... So, what do people recommend? Can anyone point out some good websites for translating this kind of terminology? The usual online translation tools are a bit too everyday English/French, not the slightly more specialised version that I find myself needing.

• Good C++ books regarding Performance?

  - by Leon

  Besides the books everyone knows about, like Meyer's 3 Effective C++/STL books, are there any other really good C++ books specifically aimed towards performance code? Maybe this is for gaming, telecommunications, finance/high frequency etc? When I say performance I mean things where a normal C++ book wouldnt bother advising because the gain in performance isn't worthwhile for 95% of C++ developers. Maybe suggestions like avoiding virtual pointers, going into great depth about inlining etc? A book going into great depth on C++ memory allocation or multithreading performance would obviously be very useful.

• CVSNT to CVSNT Migrations

  - by BParker

  Has anybody re-homed a CVSNT installation? I need to take a CVSNT setup on one ageing server and relocate it to a new shiny server, but i don't have a great deal of experience with this software. Does anyone know the basic process for moving an entire repository to a new server? We have 3 base repositories, totaling about 6GB. Size wise it's not too big, but i need to make sure all the history is migrated correctly. I've googled around a bit, but not managed to find any info on this kind of move, everyone seems to prefer to write how-to's on moving to Subversion et al.... The CVSNT server is running on windows if that makes a great deal of difference....

• adress-chunk: separate data stored in one collumn - into three (street, postal-code, town)

  - by zero

  hello dear community. Hello dear friends form all over the planet first of all - this is a great great forum. I like this place to share the ideas. It is so great to see such a supportive place - featuring the knowledge exchange! today i have the following thing to discuss: i want to separate the following data that are stored in one column of a calc-spreadsheet: See the following data: You see that there are the following categories:_ steet, postal-code, town All the data are stored in only one Colum; Well to be honest: i want to separate them into three colums steet, postal-code, town see the data: what can i do? note - you see that there are commas inbetween the enties: and besides this we see that we have a postal-code with four digits: that is a good thing. Perhaps we can use this as a marker that helps us to separate the data?! Perhaps See a data-sample! Here you can see some exceptions: eg. the town that has two words combinde with a "-" ... or somethims without any signs and characters... see the following... as an example: Max-Bader-Platz 1, 5620 Schwarzach im Pongau Pestalozzistraße 4, 9990 Nussdorf-Debant Schulstraße 4, 5162 Obertrum am See But i guess that this means no problem... What do you think about this? I am very very interested to get your opinion! i look forward to hear from you! regards see a snipped of the dataset - that is stored in one column -[b]Goal: [/b]i want to separate the datas into three collumns... : Schulweg 6, 9871 Seeboden Khevenhüllerstraße 45, 4861 Schörfling Franz Xaver Rennstr.18, 6460 Imst Schulstraße 4, 5162 Obertrum am See Schulweg 6, 7432 Oberschützen Pestalozzistraße 4, 9990 Nussdorf-Debant Niederndorf bei Kufstein 53c, 6342 Niederndorf bei Kufstein Hauptschulstraße 18, 2183 Neusiedl an der Zaya Seeweg 14, 5202 Neumarkt am Wallersee Europaplatz 1, 8820 Neumarkt in Steiermark Schulstraße 7, 4212 Neumarkt im Mühlkreis Schulstraße 20, 4720 Neumarkt im Hausruckkreis Bahnhofstr. 10, 4872 Neukirchen an der Vöckla Schulstraße 5b, 4780 Schärding Reitbergstraße 2, 4311 Schwertberg Europaplatz 1, 2320 Schwechat Am Schulberg 5, 3931 Schweiggers Waidach 8, 6130 Schwaz Waidach 8, 6130 Schwaz Max-Bader-Platz 1, 5620 Schwarzach im Pongau Markt 29, 2662 Schwarzau im Gebirge Hofsteigstraße 68, 6858 Schwarzach Gmundner Straße 7, 4690 Schwanenstadt Mühlfeldstraße 1, 4690 Schwanenstadt Mainsdorferstraße 18, 8541 Schwanberg Jakob Stemer-Weg 3, 6780 Schruns Obere Umfahrungsstraße 16, 2432 Schwadorf bei Wien Battloggstraße 54, 6780 Schruns Schloss-Straße 19, 5020 Salzburg Schillerplatz 2, 8280 Fürstenfeld Erzherzog-Johann-Str. 400, 8970 Schladming Schulgasse 261, 8811 Scheifling i look forward to hear from you!! regards

• What tasks should be explicitly mentioned in a job reference? [closed]

  - by Martin

  Glossary A job reference (see also the german version) is a letter from the (former) employer that states what the employee did, and how well he did it. There are oh so weird rules here on how to phrase stuff therein, but this is not what this question is about. Question I hope this can even be generally answered, but even if country/region specific, I think there is enough international know-how on this site to get useful answers for different regions. I was wondering how detailed the tasks a programmer / developer did should be spelled out in a job reference. (After all, they can be spelled out in all detail in a CV when applying for a new job.) So how much detail is usual for a job reference? Example Developed Windows applications in C++ or Developed Windows Desktop Applications using C++ with MS Visual Studio 2005 and MFC, utilising Boost 1.47 and specif library xyz, focusing on subsystem abc for numerical calculations of ... etc. What makes more sense?

• How many questions is it appropriate to ask as an intern?

  - by Casey Patton

  So, I just started an internship, and I'm worried that I'm asking too many questions. I've been assigned a mentor who has been assigning me projects and helping me learn all the company's technologies and methodologies. However, there's so much new material for me to learn while doing this project that I have a lot of questions. I generally ask questions over instant messages or E-mail (those are the primary modes of communication for my company). I'm trying to be careful not to ask too many questions: I don't want to come off as annoying or dumb. How many questions is appropriate to ask? Once an hour? More? Less? Keep in mind, my mentor is also a fellow programmer that has his own responsibilities.

• SQLRally Nordic gets underway

  - by Rob Farley

  PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

• Sales Manager: "Why is time-estimation so complex?"

  - by Tim

  A few days ago a sales manager asked me that question. But at this moment I didn't know a answer which he can understand. He isn't a programmer! At the moment I work on a product which is over 8 years old. Nobody thought about architecture or evolvability. I have a swamp of code in front of me every day which is not tested. Because of that, time estimates are very difficult for me. How I can describe that problem to an salesman? Not only my swamp-code-problem, but general!

• Wake timers don't wake computer from sleep mode

  - by Joe

  I'm got a custom built PC running 64 bit Windows 7 Ultimate. So far everything works great except for one thing: it will not wake up from sleep mode for a wake timer or scheduled task. Sleep mode itself works great. If it's sleeping, it wakes successfully when I press the power button, mash the keyboard, wiggle the mouse, or send a WOL packet. The only problem is wake timers. I even tried the program WakeupOnStandBy but it looks like that uses wake timers, so it doesn't do anything for me either. And yes, wake timers are enabled: Any ideas on how to fix the problem, or troubleshoot it? I'd imagine that there would be a log somewhere telling me exactly why the wake timers are having trouble, but if there is I haven't found it.

• Should I use XNA (C#) or Java to create a basic game engine?

  - by Xboxking

  My project is to design and build a game engine (in just about 3 months). I've been looking at two options for this game engine, either make it with XNA (and C#) or Java. My experience with XNA/C# is zero to none, however I have been a Java programmer for around 4 years. I've had a little play around with both but I am still not sure what would be best to use (i.e. what would turn out better with my experience). XNA is obviously for making games and I would presume making a game engine would be slightly easier in this - however that said, there are numerous libraries available in Java that could be used for a game engine (such as lwjgl). What would be my best option and ideally produce the best results out of both XNA or Java? For your information, the game engine at the moment is a 2D one and is not too advanced (although I plan to extend it in the future). Thanks in advance for all answers!

• Engineering as a Service

  - by jgelhaus

  Oracle Exadata Database Machine is known for great compute performance, and over the past few years, it has also become known as a great platform for any type of Oracle Database workload, from data warehousing to online transaction processing (OLTP). But now organizations are turning to Oracle Exadata for business efficiencies and private cloud solutions—for consolidation and database as a service (DBaaS). University of Minnesota For an inside look at how DBaaS is working in the real world, it’s worth checking into the University of Minnesota’s database hotel.  With more than 50,000 students, the University of Minnesota in Minneapolis is one of the largest universities in the United States. The university’s centralized IT group not only has to support all those students but also must provide support and services to more than 40 departments and colleges within the university. They have two Exadata Database Machine X2-2 half-rack systems from Oracle, with four database nodes each and roughly 30 terabytes of usable disk space for each of the Oracle Exadata systems. The university is using Oracle Real Application Clusters (Oracle RAC) for high availability and the Data Guard feature of Oracle Database, Enterprise Edition, for disaster recovery capabilities. The deployment has been live in production since May 2011. Overhead Door When it comes to overhead, revolving, sliding, or other specialty residential and commercial doors, Overhead Door is the worldwide leader. But when they needed to open doors with their customers through a better, faster, and more agile IT infrastructure, Overhead Door turned to Oracle and Oracle Exadata. Oracle Exadata Database Machine plays an important part in Overhead Door’s IT and business strategy. The organization has two Exadata Database Machine X2-2s deployed, one in production and one in development and testing Read the full Oracle Magazine article Engineering as a Service

• Is it worth to learn programming for windows?

  - by Herr Kaleun

  as a programmer, i was skeptical about (Microsoft) desktop software back in the early 2000s (i was a kid then) and yet, i was right. So i advanced to PHP in 2004 and began working on Web applications. When i look at the software world today, i really can't understand, how software for Microsoft or call it, "windows" should have a future. Is it still worth, learning it? I have a strong feeling that, in about 3-4 years, mac will have the dominance in the Personal Computer market. If i am wrong, please correct me. Thanks!

• I'm doing hobby programming; what programming methodologies (e.g. XP, Agile...) do you recommend me to read up on?

  - by Anto

  Most of you would probably just call me a kid (I'm 15). I'm doing hobby programming (I started fiddling around with ActionScript 2.0 in Flash 8 when I was 11, now I do mostly C, Python and Java). As I'm 15, I won't get a job for a long period of time (I'm going to spend years in academia before that) and thus this question is not about which programming methodologies you recommend me to read up on for a software engineering job, but instead which methodologies should a hobby programmer read about? What will a hobby developer learn from reading about your recommendation(s)?

• Search inside Xournal files (.xoj)

  - by Javad Sadeqzadeh

  I'm a big fan of Evernote, I use it regularly. However, it has a 60MB storage limit (although text files are not going to occupy much space, but the limitation concern still remains). Today, I installed Xournal, which has great features like annotating, nice background, free hand shapes and notes, save in PDF format, and many more. But the big problem is that as far as I've noticd, there is no intrinsic feature for seach inside the notes (created using Xournal with .xoj suffix). I used Catfish File Search application (which creates bash commands for full text search), but it couldn't help as well. Is there anyway to search inside a .xoj file at all? If so, it could be a suitable alternative to evernote, if you put your .xoj files on a cloud (which certainly offers you much more storage space than 60MB). If not, is there any other convenient app similar to Evernote, but with higher storage limit or without a limit? Somebody suggested Zim desktop wiki app, which looks great, but I'm nut sure if I could copy and paste everything there (a mixture of photos and tables and text with various formats and highlights), like what I do with Evernote. And a very useful tool I use is Evernote Web Clipper (browser extension). Of course, having a desktop client like Everpad is a plus, but not the absolute need. PS: I use pocket, so please do suggest that (it only preserve links (which might change over time) not the actual text). I also use google drive or docs, I don't like that for this purpose niether, it's too slow, doesn't have a browser extension and a desktop client. Thank you so much in advance.

• Collision Resolution

  - by ultifinitus

  Hey all, I'm making a simple side-scrolling game, and I would appreciate some input! My collision detection system is a simple bounding box detection, so it's really easy to implement. However my collision resolution is ridiculous! Currently I have a little formula like this: if (colliding(firstObject,secondObject)) firstObject.resolve_collision(yAxisOffset); if (colliding(firstObject,secondObject)) firstObject.resolve_collision(xAxisOffset); where yAxisOffset is only set if the first object's previous y position was outside the second object's collision frame, respectively xAxisOffset as well. Now this is working great, in general. However there is a single problem. When I have a stack of objects and I push the first object against that stack, the first object get's "stuck," on the stack. What's I think is happening is the object's collision system checks and resolves for collisions based on creation time, so If I check one axis, then the other, the object will "sink" object directly along the checking axis. This sinking action causes the collision detection routine to think there's a gap between our position and the other object's position, and when I finally check the object that I've already sunk into, my object's position is resolved to it's original position... All this is great, and I'm sure if I bang my head against a wall long enough i'll come up with a working algorithm, but I'd rather not =). So what in the heck do you think I should do? How could I change my collision resolution system to fix this? Here's the program (temporary link, not sure how long it'll last) (notes: arrow keys to navigate, click to drop block, x to jump) I'd appreciate any help you can offer!

• What data is available regarding cowboy coding?

  - by Christine

  I'm not a programmer; I'm a freelance writer and researcher. I have a client who is looking for stats on certain "threats" to the apps market in general (not any specific app store). One of them is cowboy coding: specifically, he wants to see numbers regarding how many apps have failed to function as intended/crashed/removed because of errors made by, in essence, sloppy coding. Note that I'm not here to debate the merits of cowboy coding, and whether or not it is sloppy. Is there any data about this type of development?

• How to approach big developer companies if I have a killer game idea? (for mobile devices)

  - by Balázs Dávid

  I have an idea for a game that has a potential, but I'm not a programmer. How to tell this to development companies without being my idea stolen? All I want from the company is first to watch a 3-minute long video presentation about my idea and if they see fantasy in it then we can talk about the details. I have already sent an e-mail to several big companies that have the expertise needed to code the game, they haven't answer me. Actually the idea is nothing fancy, no 3D, but fun and unique.

• updater stuck on downloading python files

  - by Tim

  However i am a java programmer is consider myself as a linux noob. So i could use a little help here... I am trying to update my ubuntu from version 10.04 to 12.04.1 (LTS). The downloading start and runs at around 10MB/s untill i am somewhere near 26% and the speed just drops to 0. I figured i could use the command "do-release-update" so i could see what it was doing. Again the same occured: the downloading stucked on 26% at "http://nl.archive.ubuntu.com/ubunutu/ precise/main python-qt4 1386 4.9.1-2ubuntu1". It says it downloaded 41% of that file/package. It also tries another wget on the same file every X seconds. Help? Greetings Tim, Holland.

• Can "go" replace C++? [closed]

  - by iammilind

  I was reading wiki article about "go" programming language, where Bruce Eckel states: The complexity of C++ (even more complexity has been added in the new C++), and the resulting impact on productivity, is no longer justified. All the hoops that the C++ programmer had to jump through in order to use a C-compatible language make no sense anymore --they're just a waste of time and effort. Now, Go makes much more sense for the class of problems that C++ was originally intended to solve. Can go really replace C++(11) for new development in future? How about generic programming? I don't know go , but the amount of time (in)wasted in learning C++ seems to go in vain.
