Need Directions to become a programmer [closed]

- by Omin

Before youguys go on about how there are many types of programmers, please read through the post. Long term goal: Develop my own software (company) Short term goal: Get a job that involves coding/programming Current status: Support Analyst (at a software company but does not involve any programming) with 40k salary, 3rd year computer engineering student I had everything figured out. I'm going to develop a 2D scrolling game for iphone or android, publish the app, sell a bunch, and then apply at a studios as a software developer. And then something hit me. I think I need to get a job that involes programming to learn as much as I can in the shortest time possible. So I got a phone interview at a fast growing start up software company, passed that no problem, but then had to take an online technical assessment. That failed miserably. I thought that if I could just present myself, show that I am hard working, positive attitude, eager to make self improvements, type of a guy, I could get the job. I was wrong. And now, I am lost. Im thinking of staying with my job until I find a new one as a programmer. I will be working, self studying, and trying to make this happen without finishing university. I forgot to mention that the online technical assessment was based on data structures/algorithms, OO design, runtime complexity. I was hoping that I could get some guidence. Should I be focusing on app development or study computer science fundamentals? I have a list of books I can be going through: Learning C# O'Reilly (I got interested in C# because of Unity3D and Mono), C# 5.0 in a Nutshell, Head First Design Patterns, Code Complete, Introduction to Algorithms, Programming Interviews Exposed, Cracking the Coding Interview, The Google Resume.

How do you plan your asynchronous code?

- by NullOrEmpty

I created a library that is a invoker for a web service somewhere else. The library exposes asynchronous methods, since web service calls are a good candidate for that matter. At the beginning everything was just fine, I had methods with easy to understand operations in a CRUD fashion, since the library is a kind of repository. But then business logic started to become complex, and some of the procedures involves the chaining of many of these asynchronous operations, sometimes with different paths depending on the result value, etc.. etc.. Suddenly, everything is very messy, to stop the execution in a break point it is not very helpful, to find out what is going on or where in the process timeline have you stopped become a pain... Development becomes less quick, less agile, and to catch those bugs that happens once in a 1000 times becomes a hell. From the technical point, a repository that exposes asynchronous methods looked like a good idea, because some persistence layers could have delays, and you can use the async approach to do the most of your hardware. But from the functional point of view, things became very complex, and considering those procedures where a dozen of different calls were needed... I don't know the real value of the improvement. After read about TPL for a while, it looked like a good idea for managing tasks, but in the moment you have to combine them and start to reuse existing functionality, things become very messy. I have had a good experience using it for very concrete scenarios, but bad experience using them broadly. How do you work asynchronously? Do you use it always? Or just for long running processes? Thanks.

How to make sure you server NIC performance is at best on Windows?

- by Bobb

I realised that I followed some obscure paper on setting NICs on Windows for too long. It might be outdated with new hardware released in past couple of years and with W2008R2. I read a bit about offloading and RSS settings on Windows and I realiased that it is very much circumstantial. Noone can really say - enable that and disable this. etc. So what I really want is for my next server try and setup testing environment and measure how my particular application will behave with different settings. The target is going to be latency of TCP primarily. Please note I am talking about latency inside the box. Are there precision tools for Windows to measure latency (down to microseconds)? P.S. I know this is not easy question. Windows time drift is awful problem for any precision test but still I am sure I am not the fist person to need that... Please share your experience

Inspiring People

- by barrem23

So I work with a few people that I feel are intelligent but don't seem to be working out well. After working with them for a while I have seen the flashes of brilliance but mostly I see a reliance on others. What I mean by this is that most times it seems like at the first moment of trouble they go ask for help. Now personally I am all for helping and spend a significant portion of time helping others with whatever they need, but after helping others for so long I have noticed a disturbing trend. These people seem terrified that they might make a mistake and because of this they don't try. So my question is how can I motivate someone who is afraid of making a mistake? In my career I have always learned the most by making mistakes and learning from them. Personally I feel that if I hadn't learned so much I would never have made it as far as I have. So how can I get them to discover that they have the ability to figure it out themselves and that if they make a mistake and learn from it they will be better off. I feel that if I can discover some way to properly motivate them that we all will be better off.

Cannot boot: FGLRX 8.780 + Kernel 2.6.35-25

- by pluc

The situation before this all happened is pretty standard. I have a HP Pavillion dv5 laptop with an ATI Mobility Radeon 4200 series. It always worked fine with Ubuntu for as long as I can remember. However, at one point, something happened and truly made a majestic mess of things. It might've been extra repos I enabled with Ubuntu Tweak - I do not know. But something made it so that my system would not boot any longer. And when I say "won't boot", this is what I mean: - Durning a normal bootup, any entries (except Windows) selected with GRUB (or BURG, not even sure which one I'm using anymore) will spawn the Ubuntu loading screen - then try to start X (or GDM) 5 times. The screen goes to dark, black and back to the Ubuntu loading screen. Then it just stays there until I spawn another TTY. I have no idea what is happening or why. There are no errors in my logs, and I'm truly at a loss here. I've linked three files: Xorg.0.log, the output of dmesg and the GDM log: Xorg.0.log: http://ubuntu.pastebin.com/tpVKc2tc dmesg: ubuntu.pastebin.com/Nd5aYj45 gdm's :0.log: couldn't post due to lack of points :( Let me know if any of you more knowledgeable folks can restore some sanity in my life. Any help is greatly apreciated.

Find last of match string automatically

- by jowan

I want to make id for entries as long as 7 digits.. while first entry is created, it will get id is 0000001 And my problem is i want to get id and add to 1 every time new entry is created.. I have a bunch of code and still confuse to implement it. $str_rep = "0000123"; $str_rep2 = "0005123"; // My character string can be like this $str_rep3 = "0009123"; // My character string can be like this $match_number= array(1,2,3,4,5,6,7,8,9); // I create array to do it automatically but it was not work. // I do it manually $get_str = strstr($str_rep, "1"); $get_str = strstr($str_rep2, "5"); $get_str = strstr($str_rep3, "9"); // Result echo $get_str . "<br>"; echo $get_str2 . "<br>"; echo $get_str3 . "<br>"; Thanks in advance

New whitepaper: Evolution from the Traditional Data Center to Exalogic: An Operational Perspective

- by Javier Puerta

IT organizations are struggling with the need to balance the day-to-day concerns of data center management against the business level requirements to deliver long-term value. This balancing act has proven difficult and inefficient: systems and application management tools are resource intensive and traditional infrastructure management architectures have developed over time on a project by project basis. These traditional management systems consist of multiple tools that require administrators to waste time performing too many steps to handle routine administrative tasks. Operational efficiency and agility in your enterprise are directly linked to the capabilities provided by the management layer across the entire stack, from the application, middleware, operating system, compute, network and storage. Only when this end to end capability is provided will we experience the full benefit of a scalable, efficient, responsive and secure datacenter. Managing Exalogic is substantially less complex and error prone than managing traditional systems built from individually sourced, multi-vendor components because Exalogic is designed to be administered and maintained as a single, integrated system (Figure 1). It is at the forefront of the industry-wide shift away from costly and inferior one-off platforms toward private clouds and Engineered Systems.

Community TFS Build Manager available for Visual Studio 2012 RC

- by Jakob Ehn

I finally got around to push out a version of the Community TFS Build Manager that is compatible with Visual Studio 2012 RC. Unfortunately I had to do this as a separate extension, it references different versions of the TFS assemblies and also some properties and methods that the 2010 version uses are now obsolete in the TFS 2012 API. To download it, just open the Extension Manager, select Online and search for TFS Build: You can also download it from this link: http://visualstudiogallery.msdn.microsoft.com/cfdb84b4-285e-4eeb-9fa9-dad9bfe2cd10 The functionality is identical to the 2010 version, the only difference is that you can’t start it from the Team Explorer Builds node (since the TE has been completely rewritten and the extension API’s are not yet published). So, to start it you must use the Tools menu: We will continue shipping updates to both versions in the future, as long as it functionality that is compatible with both TFS 2010 and TFS 2012. You might also note that the color scheme used for the build manager doesn’t look as good with the VS2012 theme…. Hope you will enjoy the tool in Visual Studio 2012 as well. I want to thank all the people who have downloaded and used the 2010 version! For feedback, feature requests, bug reports please post this to the CodePlex site: http://tfsbuildextensions.codeplex.com

Dell XT on Windows 7 never recovers from sleep

- by user39408

My Dell XT, after upgrade to windows 7 ultimate seems to never recover from a sleep i.e. opening the lid shows a flicker, and then all lights go off. When I press the power button long enough it reboots and says that Windows had a serious error, blah blah (but no BSOD). Hibernate doesnt cause any problem, and that is what I am doing as default. Any idea how to debug more and fix it. Looked around (on web) for answer, tried related solutions (hotfixes for similar but not same problems) etc, but noting fixes this.

Is it possible to cause artificial network packet loss or latency?

- by nbolton

I'm trying to reproduce some issues on a deployed application where the MSSQL server and client are running in two separate machines. I think there may be network issues between the two machines, so I'd like to try and reproduce these conditions on two Hyper-V virtual machines (on the same virtual server). Of course, the network for these virtual machines is "local" so it's actually far from the conditions in a live environment. Is there a program I can run on either virtual machine which will degrade the network performance? Or maybe any other work arounds? For example, one way to reproduce the conditions may be to run the VMs on separate Hyper-V servers in geographically dispersed locations (so the SQL traffic goes over VPN or something) -- but this is a little long winded I think. There must be a simpler way.

Monitoring the wall time of a process on windows?

- by Sean Madden

Windows Task Manager has the ability to show the current CPU time of any given running process on windows, is there any way (not necessarily through Task Manager) to get the current wall time of a process? An example, let's say I have a script that reliably runs for about 45 minutes. Without adding a progress bar to the script, is there any way to figure out for how long it has been running? The math behind this seems pretty straight forward; WallTime = CurrentWallTime - WallTimeProcessStarted. Likewise, since the math is so simple, is there anyway to get the time that a process was started at?

nVidia 9800 GTX+ X11 fails to initialize. no unity or lightdm

- by rlemon

I have just upgraded my work pc to 12.04 (not upgrade, fresh install), installing updates during the install, and after everything has loaded (with no errors) and I restart I get brought to console 1 tty login. Console 7 looks like this: IIRC I did not have to finagle with my drivers on 11.10 to get this card working. If this is in fact a driver bug I will remove this post and submit the bug but i'm not 100% confident that it is. I attempted to run unity --reset and got this: Lastly I tried $ sudo apt-get install nvidia-current which tells me nvidia-current is already the newest version. so I ran $ sudo dpkg-reconfigure nvidia-current which says /usr/sbin/dpkg-reconfigure: nvidia-current is broken or not fully installed. Anything I can try from here would be awesome. Currently the only way to get the system up and running was to shut down, plug one of my monitors into the onboard video, enable the onboard video card from the BIOS, then boot back up (and on my single monitor everything is fine). update So I have been able to boot fresh with the ext card plugged in as long as I don't take the updates with the install. past this if I only install the nvidia drivers (nvidia-current or nvidia-current-updates) from the main server (or canadian) I then get the problems.. My proposal; which I don't know where to look for: Can I try installing the previous version of this driver? In the past, on another machine I had issues with my NIC driver being funky... downgraded to the previous driver and bam everything was merry and well.

Looking for Unix tool/script that, given an input path, will compress every batch of uncompressed 100MB text files into a single gzip file

- by newToFlume

I have a dump of thousands of small text files (1-5MB) large, each containing lines of text. I need to "batch" them up, so that each batch is of a fixed size - say 100MB, and compress that batch. Now that batch could be: A single file that is just a 'cat' of the contents of the individual text files, or Just the individual text files themselves Caveats: unix split -b will not work here as I need to keep lines of text intact. Using the lines option is a bit complicated as there is a large variance in the number of bytes in each line. The files need not be a fixed size strictly, as long as it's within 5% of the requested size The lines are critical, and should not be lost: I need to confirm that the input made its way to output without loss - what rolling checksum (something like CRC32, BUT better/"stronger" in face of collisions) A script should do nicely, but this seems like a task someone has done before, and it would be nice to see some code (preferably python or ruby) that does atleast something similar.

check_postgres_checkpoint plugin error

- by Iliyas

I am using the check_postgres.pl plugin for Nagios. I am trying to monitor how long since the last checkpoint has been run using the check_postgres_checkpoint option. When I run the command from CLI as root I am getting the output but I am not able to get the output in the Nagios web interface. The error which it shows is, ERROR: pg_controldata could not read the given data directory: "/opt/PostgreSQL/9.1/data" It is trying to access the pg_control file in the 'global' directory present beneath the data directory which has only read access to the postgres user. Can anyone please suggest me how this can be resolved ? Thanks.

Prevent Nautilus from displaying thumbnails on a specific mount

- by Zakhar

I have written a filesystem over Fuse to access a remote pseudo-NAS (the French "Freebox V6", I'll soon publish it as GPL3... when it's a little bit more polished!). The NAS is connected to a home ADSL, thus data comes down at the upload speed of ADSL, which is at best 1Mbps. My mount works fine (read-only at the moment), but Nautilus sees the mountpoint (and all sub-directories) as a "local" filesystem and tries to make thumbnails. As I have a directory full of images, this is quite horrible, because Nautilus then opens ALL the images to try to display the thumbnail. I could switch the Nautilus preferences to "Never" for thumbnails, but then I'll loose thumbnails on my "real" local filesystem. So the question is: with the preference "Only for local filesystem", how can I instruct Nautilus that my mountpoint is in fact NOT a local mount so that it will stop trying to draw thumbnails on that specific mount, but continue "thumbnailing" on mounts that are really local? Edit note: the same things happens if you use "standard worldwide" mounts such as sshfs, davfs,... as long as you mount over a relatively slow network (ADSL) and have images/movies on your mounted tree.

Linux live cd with Broadcom Wi-fi support

- by paul simmons

I am looking for a live distro that has out of the box Broadcom wireless support. I am pretty happy with my Ubuntu installation and as long as I have an ethernet connection first time installed, I can install Broadcom drivers over internet. But being a little paranoid, I make my secure operations (banking etc.) with a live cd and zero hard disk access, so nothing is recorded. So far I plug ethernet to do such things with the live cd, but it would be nice if I can do same thing with wireless.

When decomposing a large function, how can I avoid the complexity from the extra subfunctions?

- by missingno

Say I have a large function like the following: function do_lots_of_stuff(){ { //subpart 1 ... } ... { //subpart N ... } } a common pattern is to decompose it into subfunctions function do_lots_of_stuff(){ subpart_1(...) subpart_2(...) ... subpart_N(...) } I usually find that decomposition has two main advantages: The decomposed function becomes much smaller. This can help people read it without getting lost in the details. Parameters have to be explicitly passed to the underlying subfunctions, instead of being implicitly available by just being in scope. This can help readability and modularity in some situations. However, I also find that decomposition has some disadvantages: There are no guarantees that the subfunctions "belong" to do_lots_of_stuff so there is nothing stopping someone from accidentally calling them from a wrong place. A module's complexity grows quadratically with the number of functions we add to it. (There are more possible ways for things to call each other) Therefore: Are there useful convention or coding styles that help me balance the pros and cons of function decomposition or should I just use an editor with code folding and call it a day? EDIT: This problem also applies to functional code (although in a less pressing manner). For example, in a functional setting we would have the subparts be returning values that are combined in the end and the decomposition problem of having lots of subfunctions being able to use each other is still present. We can't always assume that the problem domain will be able to be modeled on just some small simple types with just a few highly orthogonal functions. There will always be complicated algorithms or long lists of business rules that we still want to correctly be able to deal with. function do_lots_of_stuff(){ p1 = subpart_1() p2 = subpart_2() pN = subpart_N() return assembleStuff(p1, p2, ..., pN) }

Who wants to keep developing?

- by wcm

I'm a bit older than most of my peers, having come into programming in my mid 30's. The thing is, I love what I do. Most of my project managers and bosses are my age or younger. I'm really OK with that. I, however, have no desire to climb the company ladder. While I regularly take on the responsibility of making sure that projects get done and my peers often look to me for programming and architectural guidance, I just like writing code and want to keep doing it for as long as possible. Honestly, my only real goal is grow into being a crusty old tech lead until I retire. IF I retire. I would so much rather learn the latest and greatest new technology than PMP my resume. Are there others out there who feel like this because I often feel rather alone in my pathology? EDIT Something I didn't make clear is that I really like helping and mentoring other developers. It makes me feel good and useful and (to be brutaly honest) important.

Options to Reformat USB Drive

- by user8783

I have a 64GB usb thumb drive. When I plug it into a Windows system (I have tried several machines with both Windows 7 and 8), the system attempts to read it and never completes. The drive does not show up in the device manager, nor does it appear in Computer Management - Disk Management. If I click on the "Safely Remove Hardware" icon, however, I do get an option for "Eject Mass Storage Media", although it never accomplishes anything. Also, as long as the USB drive is connected, I cannot access other USB drives or even restart my computer. It seems as though it locks up Windows Explorer. Is there any option to reformat this drive? It was a great drive up until all this craziness began and I would hate to throw it out because it was rather pricey.

Alternatives to time tracking methodologies [closed]

- by Brandon Wamboldt

Question first: What are some feasible alternatives to time tracking for employees in a web/software development company, and why are they better options Explanation: I work at a company where we work like this. Everybody is paid salary. We have 3 types of work, Contract, Adhoc and Internal (Non billable). Adhoc is just small changes that take a few hours and we just bill the client at the end of the month. Contracts are signed and we have this big long process, the usual. We figure out how much to charge by getting an estimation of the time involved (From the design and the developers), multiplying it by our hourly rate and that's it. So say we estimate 50 hours for a website. We have time tracking software and have to record the time in 15 we spend on it (7:00 to 7:15 for example), the project name, and give it some comments. Now if we go over the 50 hours, we are both losing money and are inefficient. Now that I've explained how the system works, my question is how else can it be done if a better method exists (Which I'm sure one must). Nobody here likes the current system, we just can't find an alternative. I'd be more than willing to work after hours longer hours on a project to get it done in time, but I'm much inclined to do so with the current system. I'd love to be able to sum up (Or link) to this post for my manager to show them why we should use abc system instead of this system.

How can I change the default date format?

- by RossFabricant

When I paste a date into Excel 2010 in the format "2012-12-07 00:00:00.000" I'd like it to be displayed by default as "2012-12-07", but it is actually displayed as "00:00.0". I know I can work around this by prepending a ' or changing the cell format, but I'm interested in changing the default format. An approach that almost works is going to Control Panel-Region and Language-Long Time format and changing it to something like "h". This results in Excel displaying the dates I paste in as "2012-12-07 00:00:00.000", but screws up times displayed outside of Excel. The dates I'm pasting in are from SQL Server.
