  • My Feelings About Microsoft Surface

    - by Valter Minute
    Advice: read the title carefully, I’m talking about “feelings” and not about advanced technical points proved in a scientific and objective way I still haven’t had a chance to play with a MS Surface tablet (I would love to, of course) and so my ideas just came from reading different articles on the net and MS official statements. Remember also that the MVP motto begins with “Independent” (“Independent Experts. Real World Answers.”) and this is just my humble opinion about a product and a technology. I know that, being an MS MVP you can be called an “MS-fanboy”, I don’t care, I hope that people can appreciate my opinion, even if it doesn’t match theirs. The “Surface” brand can be confusing for techies that knew the “original” surface concept but I think that will be a fresh new brand name for most of the people out there. But marketing department are here to confuse people… so I can understand this “recycle” of an existing name. So Microsoft is entering the hardware arena… for me this is good news. Microsoft developed some nice hardware in the past: the xbox, zune (even if the commercial success was quite limited) and, last but not least, the two arc mices (old and new model) that I use and appreciate. In the past Microsoft worked with OEMs and that model lead to good and bad things. Good thing (for microsoft, at least) is market domination by windows-based PCs that only in the last years has been reduced by the return of the Mac and tablets. Google is also moving in the hardware business with its acquisition of Motorola, and Apple leveraged his control of both the hardware and software sides to develop innovative products. Microsoft can scare OEMs and make them fly away from windows (but where?) or just lead the pack, showing how devices should be designed to compete in the market and bring back some of the innovation that disappeared from recent PC products (look at the shelves of your favorite electronics store and try to distinguish a laptop between the huge mass of anonymous PCs on displays… only Macs shine out there…). Having to compete with MS “official” hardware will force OEMs to develop better product and bring back some real competition in a market that was ruled only by prices (the lower the better even when that means low quality) and no innovative features at all (when it was the last time that a new PC surprised you?). Moving into a new market is a big and risky move, but with Windows 8 Microsoft is playing a crucial move for its future, trying to be back in the innovation run against apple and google. MS can’t afford to fail this time. I saw the new devices (the WinRT and Pro) and the specifications are scarce, misleading and confusing. The first impression is that the device looks like an iPad with a nice keyboard cover… Using “HD” and “full HD” to define display resolution instead of using the real figures and reviving the “ClearType” brand (now dead on Win8 as reported here and missed by people who hate to read text on displays, like myself) without providing clear figures (couldn’t you count those damned pixels?) seems to imply that MS was caught by surprise by apple recent “retina” displays that brought very high definition screens on tablets.Also there are no specifications about the processors used (even if some sources report NVidia Tegra for the ARM tablet and i5 for the x86 one) and expected battery life (a critical point for tablets and the point that killed Windows7 x86 based tablets). Also nothing about the price, and this will be another critical point because other platform out there already provide lots of applications and have a good user base, if MS want to enter this market tablets pricing must be competitive. There are some expansion ports (SD and USB), so no fixed storage model (even if the specs talks about 32-64GB for RT and 128-256GB for pro). I like this and don’t like the apple model where flash memory (that it’s dirt cheap used in thumdrives or SD cards) is as expensive as gold (or cocaine to have a more accurate per gram measurement) when mounted inside a tablet/phone. For big files you’ll be able to use external media and an SD card could be used to store files that don’t require super-fast SSD-like access times, I hope. To be honest I really don’t like the marketplace model and the limitation of Windows RT APIs (no local database? from a company that based a good share of its success on VB6+Access!) and lack of desktop support on the ARM (even if the support is here and has been used to port office). It’s a step toward the consumer market (where competitors are making big money), but may impact enterprise (and embedded) users that may not appreciate Windows 8 new UI or the limitations of the new app model (if you aren’t connected you are dead ). Not having compatibility with the desktop will require brand new applications and honestly made all the CPU cycles spent to convert .NET IL into real machine code in the past like a huge waste of time… as soon as a new processor architecture is supported by Windows you still have to rewrite part of your application (and MS is pushing HTML5+JS and native code more than .NET in my perception). On the other side I believe that the development experience provided by Visual Studio is still miles (or kilometres) ahead of the competition and even the all-uppercase menu of VS2012 hasn’t changed this situation. The new metro UI got mixed reviews. On my side I should say that is very pleasant to use on a touch screen, I like the minimalist design (even if sometimes is too minimal and hides stuff that, in my opinion, should be visible) but I should also say that using it with mouse and keyboard is like trying to pick your nose with boxing gloves… Metro is also very interesting for embedded devices where touch screen usage is quite common and where having an application taking all the screen is the norm. For devices like kiosks, vending machines etc. this kind of UI can be a great selling point. I don’t need a new tablet (to be honest I’m pretty happy with my wife’s iPad and with my PC), but I may change my opinion after having a chance to play a little bit with those new devices and understand what’s hidden under all this mysterious and generic announcements and specifications!

  • How to make JWM work in Ubuntu 12.04?

    - by alba
    I have installed the JWM on Ubuntu 12.04 via the Software Centre, but it doesn't work. When I choose the JWM session from LightDM, it only shows a black screen. It worked when I had another computer with Ubuntu 11.10, where I had the same problem after the JWM installation. But once, by chance, I chose to start JWM from a Fluxbox session. And after that, i was able to start JWM also from LightDM. But this solution does not work for me on Ubuntu 12.04. JWM never starts.

  • How do I learn algorithms and data structures?

    - by sushil bharwani
    this is in continuation to my previous question where i asked is it necessary to learn algorithm and datastructures. I feel yes it is. Now when i work in a enviornment where i wont ever get the chance to learn it by experimenting or practically or in any assignment. What is the right approach like the right books, right kind of problems, right kind of resources that i can go through to give six months or a year or two to learn it. And also mould my mind in a way that it can relate problems to datastructures and algos.

  • is it possible for windows viruses when downloaded through ubuntu affect my windows os

    - by fr33c0untry
    I know that Ubuntu is immune to virus so there is no question of it getting infected while browsing the net.however i frequently transfer files from my pendrive (which i get from other virus infested computers) to my own laptop and save it on the data drive which is shared by both windows and ubuntu.i would like to know if there is a chance for windows viruses which might get saved and then infect it whenever i switch to windows later on.its ironic that i scan my pendrive using avast on windows and then save all my files to my hard drive to keep my laptop free from virus eventhough i have ubuntu.can anyone suggest an alternative.thanks in advance.

  • In 12.04 LTS, I get "No DBus" errors when running things as root

    - by Seann
    While attempting to run gEdit as root from a terminal window (was trying to do some tweaking on my HOSTS and FSTAB files), I get a message saying "No DBus connection available" and get booted back to the prompt. However, I can run Nautilus from the prompt like that (still get the error, but it runs all the same), and use WINE and NOTEPAD, and was able to make my changes. I thought maybe DBUS was missing, but APT says it's installed and gEdit runs fine when not elevated. Granted, I don't have to elevate often, but on the off-chance I do, (like adding or changing SMB/CIFS mountpoints in FSTAB), I would like to use gEdit, not NOTEPAD from WINE, and not in a terminal window with VI (well VIM). Ideas? Solutions?

  • Adding unit tests to a legacy, plain C project

    - by Groo
    The title says it all. My company is reusing a legacy firmware project for a microcontroller device, written completely in plain C. There are parts which are obviously wrong and need changing, and coming from a C#/TDD background I don't like the idea of randomly refactoring stuff with no tests to assure us that functionality remains unchanged. Also, I've seen that hard to find bugs were introduced in many occasions through slightest changes (which is something which I believe would be fixed if regression testing was used). A lot of care needs to be taken to avoid these mistakes: it's hard to track a bunch of globals around the code. To summarize: How do you add unit tests to existing tightly coupled code before refactoring? What tools do you recommend? (less important, but still nice to know) I am not directly involved in writing this code (my responsibility is an app which will interact with the device in various ways), but it would be bad if good programming principles were left behind if there was a chance they could be used.

  • When acquiring a domain name for product xyz, is it still important to buy .net and .org versions too?

    - by Borek
    I am buying a domain name for service xyz and obviously I have bought .com in the first place. In the past it was automatic to also buy the .net and .org versions. However, I've been asking myself, why would I do that? To serve customers who mistakenly enter a different TLD? (Would someone accidentally do that these days?) To avoid a chance that competition will acquire those TLDs and play some dirty game on my customers? If there is a good reason, or a few, to buy the .net and .org versions these days I'd like to see those listed. Thanks.

  • How to layout application icons in the panel?

    - by Vincenzo
    Hello everybody, Application and applets icons are changing their position or even disappears from the gnome-panel (see an example). It often happens after connecting to external monitor with different resolution setting, or sometimes happens by chance (I don't know what is the reason of such behaviour). Some icons I can move, others I can't. I don't know if they're locked or not. My question is: Is there any settings/software for icon's position control in the panel? I noticed that locking does not resolve this issue. Thank you for support.

  • What route to take to become a systems developer?

    - by Ramin
    In the past I have done a lot of Java and Python coding. Mostly, I worked on web apps and some simple console or gui apps. I also have a formal education in computer science. What route should I take to become a systems developer? I always did like C++, but never had a chance to use it for anything. Would mastering C++ be one of the steps? If so what resources can you suggest? Also, I would like to know how much different is the work between plain old development and systems development. There seem to be a lot of overlapping between the two.

  • Do you think code is self documenting?

    - by Desolate Planet
    This is a question that was put to me many years ago as a gradute in a job interview and it's nagged at my brain now and again and I've never really found a good answer that satisfied me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

  • converting 2d grid of squares to polygon nav mesh

    - by Roflha
    I haven't actually started programming for this one yet, but I wanted to see how I would go about doing this anyway. Say I have a 2D matrix of squares, all of the same size, some traversable and some not. How would I go about creating a navigation mesh of polygons from this grid. Is there any reading I can look at until I get a chance to get to my computer or should I just give it a go. My idea was to take the non-traversable squares out and extend lines from there edges to make polygons.. that's all I have got so far. Any advice?

  • Open-Source, Consensus-Based Development

    - by user20037
    Question: Is there an open source license that requires that my name (or a name that I want to promote) will always be associated with a project and derivations of it? (Either within the copyright notice (©) or other.) Motivation: - My main motivation is to gain reputation. If it gained wide use, it could look very good on resume (I understand this is a long shot). - An additional benefit is that it would explicitly state to prospective employers that this code was used by myself before I started with the company and will continue to be used when I leave. It is my understanding: I am aware that 99.9% of open-source projects never take off, and that I am taking a long shot in regard to advancing reputation/career. I understand that many don't read/respect licenses. I understand that open source projects take a lot of time to manage. I understand that 'Concensus-Based Development' is the best chance at motivating a community and that I may/will loose substantial control.

  • Crappy school, what to do? [closed]

    - by zhenka
    I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

  • Should a primary key be immutable?

    - by Vincent Malgrat
    A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

  • Shader inputs in a general purpouse engine

    - by dreta
    I'm not familiar with SDKs like Unity or UDK that much, so i can't check this off hand. Do general purpouse engines allow users to create custom uniform variables? The way i see it, and the way i have implemented it in an engine i'm writing to learn 3D, is that there is a "set" of uniforms provided by the engine and if you want to write a custom shader then you utilize uniforms you need to create a wanted effect. Now, the thing is, first of all i'm not an artist, second of all, i didn't have a chance to create complex scenes yet. So my question is, is it common practice to define variables that the engine provides and only allow the user to work with what they're given? Allowing users to add custom programs and use them where they want is not hard, but i have issues imagining how you'd go about doing the same for uniforms.

  • How can I optimise ext4 for reliability?

    - by amin
    As ext4 was introduced as more reliable than ext3 with block journals, is there any chance to suppose it 100% reliable? What if enabling block journaling on it, which is disabled by default? As friend's guide to explain my case in more detail: I have an embedded linux device, after installation keyboard and monitor is detached and it works standalone. My duty is to make sure it has reliable file-system so with errors there is no way for manual correct faults on device. I can't force my customer to use a ups with each device to ensure no fault by power-failure. What more can ext4 offer me besides block journaling? Thanks in advance.

  • Why is (Ogg) Vorbis not automatically supported by Windows?

    - by flying sheep
    Vorbis was never threatened by MPEG LA, so it is undoubtedly completely patent free. (MPEG LA never misses a chance to spread patent FUD) Windows supports mp3, so it isn’t because they want to push their crappy wma. The GPL allows distribution alongside commercial products, and Even if they fear to ship GPL software, they can still load it automatically, like they do with XviD So why can’t a windows customer not simply drop a ogg vorbis file into his/her music library and listen to it via WMP? PS: To counter misconceptions: They already download the GPL’d XviD codec on demand, so they already have 99% of what it takes to do the same with Vorbis. It would take me about 5 minutes to do this, if I were familiar with the WMP code base and directshow filter system. PSS: I was told to ask this here rather than on stackoverflow, so i do.

  • Efficient way to check for changes to the contents of folders

    - by MrVimes
    I am creating an application that maintains a database of files of a certain type in a given folder (and all subfolders) Initially the program will recurse the folders and add any file it finds of that type to the database. I want the application to have the ability to re-scan the folder and add any files that were not there the last time the folders were scanned. It can't use the date created property of the file because there is a high chance of a file being added to the folders that isn't a new file. I am wondering what the most efficient way of doing this is, and if there is a way that doesn't involve checking each file is in the database already (which, if there are 5000 files would mean 5000 queries of a list 5000 items in size, or 25 million 'checks' for the sql engine to perform) I suppose a more specific question to acheive the same goal would be - is there a property of a file (in Microsoft Windows) that will reliably tell you when that file arrived in that folder.
