  • Read/WRITE/Verify disk diagnostic tool for Mac OS X?

    - by Spiff
    It seems that there are many tools out there for Mac OS X that test a hard drive for bad blocks by doing a Read/Verify pass. That is, they read a block, then read it a second time, and verify that both reads yielded the same results. I need a tool that does a non-destructive Read/Write/Verify pass. It should read each block, write those same contents back out, and then read it again to verify. That way every block gets written, giving the hard drive a chance to spare out bad blocks. But since the same contents that were just read get written back out, it doesn't destroy data that wasn't already lost. I'm aware of several tools that can do Read/Verify, but I'm not aware of any that do Read/Write/Verify. Are there any tools that do what I want? Unix / open source tools that compile and run on Mac OS X are fair game too.

  • Agile development; on-line free tools!

    - by BT.
    We have been looking to implement Agile methodology within our geographically distributed development team, so i need suggestions on any free on-line application that you have used and find useful. Right now we are using paper cards and wall to manage this :), but we want to shift to an on-line version preferably free. I have used TargetProcess at my previous job! My Core requirements are: Business Analyst can add user stories We can assign, prioritize different user stories to developers. QA team can add test cases around different user stories. Project Manager can track the time of all the resources and can pull reports for upper management

  • How do I bind a jQuery Tools overlay event to an existing overlay?

    - by Paul
    Say when the page loads, this code runs: jQuery(document).ready(function($){ $('#overlay').overlay( api: true ); }); How would I bind an event to it? I've tried: $('#overlay').onBeforeLoad( function(){ alert('Hi'); }); $('#overlay').bind( 'onBeforeLoad', function(){ alert('Hi'); }); var api = $('#overlay').data('overlay'); api.onBeforeLoad(function(){ alert('Hi') }); When I do: alert(api.getContent().attr('id')); An alert pops up with '#overlay' inside. When the overlay is open and I run: alert(api.isOpened()); An alert pops up with 'false' inside. Thanks in advance.

  • ASP.NET and Winforms: What PDF reporting tools are out there and recommended?

    - by Mark Redman
    I have ActiveReports for .Net which is a great tool, however the version I have is not going to support Visual Studio 2010. Active Reports quite pricey, so just wondering if there are any better alternatives out there at a competitive price or even open source, before I consider upgrading. I am looking for a reporting tool specifically, that has a designer and is programmable etc, not looking for something that can just produce PDF, eg iTextSharp etc. Output will primarily be PDF for web and windows applications. Using various databases, SQL Server, SQL Server Express, Azure and SQLite, so not sure SQL Server reporting services will work for all these cases. All coments appreciated.

  • Microsoft Office 2010 Proofing Tools Kit

    - by Svish
    I have installed the Office 2010 available on MSDN, but there is no proofing tools kit available there yet. Still I see various sources where I can download this kit when I search for it on Google. Is the Proofing Tools Kit available yet or not? Are these sources I see on Google legitimate ones or should I stay away from them? Or are they also available from Microsoft directly somewhere I haven't looked yet? 2010-07-28 Bump: Has anything come out now? I found something called a language pack on MSDN, but the installation looked pretty much the same as the original... not quite sure what that pack did...

  • Are there any modeling tools that can visually generate jpa or sql queries?

    - by Shervin
    Does anyone know of a tool like PowerArchitect or SquirrelSQL or maybe eclipse plugin that lets you also generate jpa/sql queries? Imagine you choosing your database, or your entity beans, and the modeling would reverse engineer your database/entity model, so that you could visually just choose the columns you wanted to select, and it would generate jpa or sql queries for you. For instance choosing A.b and X.y would generate something like this: select a.b, x.y from A a, X x join ......

  • HP ProBook 4540s - Can't find HP Protect Tools to activate fingerprint reader

    - by CandiM
    I got an HP ProBook 4540s in December--When I first got it, every time I booted up, there was a rather large icon, almost like a Windows 7 gadget, to access HP Protect Tools, but I had too much going on to mess with it right away and kept clicking on something like "remind me next time I log on" and determined to get acquainted with it after the holidays--But at some point in time, that icon went away and now I can't locate it at all-- I'd like to try, and probably use, the fingerprint reader and explore whatever else is among the Protect Tools, but now I can't find them or any folder or .exe to acceess them-- Can anyone help me find them?-- Thanks so much

  • Where should custom vmware-tools scripts go

    - by Cylindric
    I have installed the VMWare Tools into a test Ubuntu guest, and it's created the standard scripts as expected: poweroff-vm-default poweron-vm-default resume-vm-default suspend-vm-default I add some custom actions to the scripts, but it says in the top of the file ########################################################################## # DO NOT modify this file directly as it will be overwritten the next # time the VMware Tools are installed. ########################################################################## So where should the custom scripts go, if I'm not supposed to modify these ones? scriptsdir="`dirname $0`/scripts/`basename $0`.d" if [ -d "$scriptsdir" ]; then for scriptfile in "$scriptsdir"/*; do [ -x "$scriptfile" ] && "$scriptfile" poweron-vm done fi

  • Hyper-V CPU Utilization, Good Tools?

    - by yzorg
    I just learned a ton from this post: Host CPU% doesn't include child VM CPU%, specifically I learned that both the 'host OS' and 'child VM' are siblings within the HyperVisor layer. Are there good utilities for 'watching' the total CPU and other resource counters at the HyperVisor (hardware) layer? I know perfmon (watching special Hyper-V CPU counters) is the standard answer, but I've stayed away from perfmon for ad-hoc monitoring. Is there a good OSS or free tools to 'watch' the resource utilization as I create multiple new VMs running on the server? I'm a developer, so if there aren't any good UI tools to surface this data I'd consider creating one, but only if needed. P.S. My specific scenario is I'm creating new web, SQL and back-end server VMs for new Windows 8 Server and SQL 2012 (entire application stack). I need to monitor them for utilization and know when I need to grow beyond 1 host (I'll need to split the VMs into separate hosts as I hit hardware limits of the 1st host, and diagnose problems).

  • Domain controller failed to restore using windows backup tools

    - by Peilin
    Domain controller failed to restore using windows backup tools One Issue: One 08 R2 domain controller with fully daily backup(only one controller in this company) is out of services due to hardware issue. The below two methods i tried to recover to the new purchasing server,but it is fail. 1)First Method: Using the windows 2008 R2 CD to boot and carry out recover from backup. Everything is OK, but after reboot it will come out blue screen and restart again. 2)Second Method: a)Install the OS in this new server b) Reboot the server to DSRM. c)Using the Windows Backup Tools to restore the system states only After reboot, it will come out the blue screen error and restart again. I know this is may be the different hardware issue, but how to resolve? Or can we only restore the AD services not whole system status? Any suggestion?

  • Issue with Visual C++ 2010 (Express) External Tools command

    - by espais
    Hi all, Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): *** couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

  • How to organize external tools in Visual Studio 2010?

    - by Hamish Grubijan
    This is how one can set them up: http://www.c-sharpcorner.com/uploadfile/rmcochran/commandpromptinstudiotoolsmenu01152008103357am/commandpromptinstudiotoolsmenu.aspx My problem is that I have got too many of them set up, and I now need a separate sub-menu or two to keep them organized. I could not figure out how to do that. Feel free to ask if something is not clear.

  • Deactivate any calls to Log before publishing: are there tools to do this?

    - by Nicolas Raoul
    According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.

  • Daemon Tools error (0xc0000006)

    - by Roberts
    I tried to reinstall Windows XP to Windows 7, but I could not install the video card drivers because the driver installation software only works on XP.I have launched the setup program with XP mode. After I installed the setup, I restarted the computer and Windows 7 wasn't booting.But that isn't the problem why I asked this question. The problem is that I have reinstalled my Windows 7 Ultimate to Windows XP SP3 and I wanted to install Dameon Tools.After installation I restarted the PC (as the setup wanted) and when the Daemon Tools launches it shows the error: Application failed to initialize properly (0xc0000006). Click OK to terminate the application.

  • An Alphabet of Eponymous Aphorisms, Programming Paradigms, Software Sayings, Annoying Alliteration

    - by Brian Schroer
    Malcolm Anderson blogged about “Einstein’s Razor” yesterday, which reminded me of my favorite software development “law”, the name of which I can never remember. It took much Wikipedia-ing to find it (Hofstadter’s Law – see below), but along the way I compiled the following list: Amara’s Law: We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run. Brook’s Law: Adding manpower to a late software project makes it later. Clarke’s Third Law: Any sufficiently advanced technology is indistinguishable from magic. Law of Demeter: Each unit should only talk to its friends; don't talk to strangers. Einstein’s Razor: “Make things as simple as possible, but not simpler” is the popular paraphrase, but what he actually said was “It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience”, an overly complicated quote which is an obvious violation of Einstein’s Razor. (You can tell by looking at a picture of Einstein that the dude was hardly an expert on razors or other grooming apparati.) Finagle's Law of Dynamic Negatives: Anything that can go wrong, will—at the worst possible moment. - O'Toole's Corollary: The perversity of the Universe tends towards a maximum. Greenspun's Tenth Rule: Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp. (Morris’s Corollary: “…including Common Lisp”) Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. Issawi’s Omelet Analogy: One cannot make an omelet without breaking eggs - but it is amazing how many eggs one can break without making a decent omelet. Jackson’s Rules of Optimization: Rule 1: Don't do it. Rule 2 (for experts only): Don't do it yet. Kaner’s Caveat: A program which perfectly meets a lousy specification is a lousy program. Liskov Substitution Principle (paraphrased): Functions that use pointers or references to base classes must be able to use objects of derived classes without knowing it Mason’s Maxim: Since human beings themselves are not fully debugged yet, there will be bugs in your code no matter what you do. Nils-Peter Nelson’s Nil I/O Rule: The fastest I/O is no I/O.    Occam's Razor: The simplest explanation is usually the correct one. Parkinson’s Law: Work expands so as to fill the time available for its completion. Quentin Tarantino’s Pie Principle: “…you want to go home have a drink and go and eat pie and talk about it.” (OK, he was talking about movies, not software, but I couldn’t find a “Q” quote about software. And wouldn’t it be cool to write a program so great that the users want to eat pie and talk about it?) Raymond’s Rule: Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter.  Sowa's Law of Standards: Whenever a major organization develops a new system as an official standard for X, the primary result is the widespread adoption of some simpler system as a de facto standard for X. Turing’s Tenet: We shall do a much better programming job, provided we approach the task with a full appreciation of its tremendous difficulty, provided that we respect the intrinsic limitations of the human mind and approach the task as very humble programmers.  Udi Dahan’s Race Condition Rule: If you think you have a race condition, you don’t understand the domain well enough. These rules didn’t exist in the age of paper, there is no reason for them to exist in the age of computers. When you have race conditions, go back to the business and find out actual rules. Van Vleck’s Kvetching: We know about as much about software quality problems as they knew about the Black Plague in the 1600s. We've seen the victims' agonies and helped burn the corpses. We don't know what causes it; we don't really know if there is only one disease. We just suffer -- and keep pouring our sewage into our water supply. Wheeler’s Law: All problems in computer science can be solved by another level of indirection... Except for the problem of too many layers of indirection. Wheeler also said “Compatibility means deliberately repeating other people's mistakes.”. The Wrong Road Rule of Mr. X (anonymous): No matter how far down the wrong road you've gone, turn back. Yourdon’s Rule of Two Feet: If you think your management doesn't know what it's doing or that your organisation turns out low-quality software crap that embarrasses you, then leave. Zawinski's Law of Software Envelopment: Every program attempts to expand until it can read mail. Zawinski is also responsible for “Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems.” He once commented about X Windows widget toolkits: “Using these toolkits is like trying to make a bookshelf out of mashed potatoes.”

  • "Guiding" a Domain Expert to Retire from Programming

    - by James Kolpack
    I've got a friend who does IT at a local non-profit where they're using a custom web application which is no longer supported by the company who built it. (out of business, support was too expensive, I'm not sure...) Development on this app started around 10+ years ago so the technologies being harnessed are pretty out of date now - classic asp using vbscript and SQL Server 2000. The application domain is in the realm of government bookkeeping - so even though the development team is long gone, there are often new requirements of this software. Enter the... The domain expert. This is an middle aged accounting whiz without much (or any?) prior development experience. He studied the pages, code and queries and learned how to ape the style of the original team which, believe me, is mediocre at best. He's very clever and very tenacious but has no experience in software beyond what he's picked up from this app. Otherwise, he's a pleasant guy to talk to and definitely knows his domain. My friend in IT, and probably his superiors in the company, want him out of the code. They view him as wasting his expertise on coding tasks he shouldn't be doing. My friend got me involved with a few small contracts which I handled without much problem - other than somewhat of a communication barrier with the domain expert. He explained the requirements very quickly, assuming prior knowledge of the domain which I do not have. This is partially his normal style, and I think maybe a bit of resentment from my involvement. So, I think he feels like the owner of the code and has entrenched himself in a development position. So... his coding technique. One of his latest endeavors was to make a page that only he could reach (theoretically - the security model for the system is wretched) where he can enter a raw SQL query, run it, and save the query to run again later. A report that I worked on had been originally implemented by him using 6 distinct queries, 3 or 4 temp tables to coordinate the data between the queries, and the final result obtained by importing the data from the final query into Access and doing a pivot and some formatting. It worked - well, some of the results were incorrect - but at what a cost! (I implemented the report in a single query with at least 1/10th the amount of code.) He edits code in notepad. He doesn't seem to know about online reference material for the languages. I recently read an article on Dr. Dobbs titled "What Makes Bad Programmers Different" - and instantly thought of our domain expert. From the article: Their code is large, messy, and bug laden. They have very superficial knowledge of their problem domain and their tools. Their code has a lot of copy/paste and they have very little interest in techniques that reduce it. The fail to account for edge cases, while inefficiently dealing with the general case. They never have time to comment their code or break it into smaller pieces. Empirical evidence plays no little role in their decisions. 5.5 out of 6. My friend is wanting me to argue the case to their management - specifically, I got this email from their manager to respond to: ...Also, I need to talk to you about what effect there is from Domain Expert continuing to make edits to the live environment. If that is a problem for you I need to know so I can have his access blocked. Some examples would help. In my opinion, from a technical standpoint, it's dangerous to have him making changes without any oversight. On the other hand, I'm just doing one-off contracts at this point and don't have much desire to get involved deeply enough that I'm essentially arguing as one of the Bobs from Office Space. I'd like to help my friend out - but I feel like I'm getting in the middle of a political battle. More importantly - if I do get involved and suggest that his editing privileges be removed, it needs to be handled carefully so that doesn't feel belittled. He is beyond a doubt the foremost expert on this system. I'm hoping this is familiar territory for some other stackechangers, because I'm feeling a little bewildered. How should I respond? Should I argue that he shouldn't be allowed to touch the code? Should I phrase it as "no single developer, no matter how experienced, should be working on production code unchecked"? Should I argue to keep him involved with the code, but with a review process? Should I say "glad I could help, but uh, I'm busy now!" Other options? Thanks a bunch!

  • Scala programming language for beginners, is it a legend?

    - by ali
    Hi every one, I am Ali from Saudi Arabia. undoubtedly, Scala is one of the best programming language for any programmer to learn, but there is "good" problems that is faced especially by beginners, and what seems frustrating that these problems won't solve soon, so as a beginner and on behalf of beginners let me raise these "objective" questions: 1- why scala has no effective and stable development platform, in fact, it suffers many problems with Eclipse, Netbeat, and Intellij. 2- although I have looked for a clear,easy, and understandable explanation of how to get started with Scala, but fortunately, there was no article or guide that deserves to spend the time I have spent to read it. nobody could tell you clear steps that fit you as a beginner who wants to start his"HELLO WORLD" with Scala, while all other languages have its "HELLO WORLD" guides and books. thank you for your time, be sure that you read notes below. 1- I have no experience in programming language before. 2- don't tell me "not to begin with scala", simply, because I will do. 3- OS is windows vista home premium. 4- I hate excuses, such as Scala is new language......etc

  • Programming texts and reference material for my Kindle DX, creating the ultimate reference device?

    - by mwilliams
    (Revisiting this topic with the release of the Kindle DX) Having owned both generation Kindle readers and now getting a Kindle DX; I'm very excited for true PDF handling on an e-ink device! An image of _Why's book on my Kindle (from my iPhone). This gives me a device capable of storing hundreds of thousands of pages that are full text search capable in the form factor of a magazine. What references (preferably PDF to preserve things such as code samples) would you recommend? Ultimately I would like reference material for every modern and applicable programming language (C, C++, Objective-C, Python, Ruby, Java, .NET (C#, Visual Basic, ASP.NET), Erlang, SQL references) as well as general programming texts and frameworks (algorithms, design patterns, theory, Rails, Django, Cocoa, ORMs, etc) and anything else that could be thought of. With so many developers here using such a wide array of languages, as a professional in your particular field, what books or references would you recommend to me for my Kindle? Creative Commons material a plus (translate that to free) as well as the material being in the PDF file format. File size is not an issue. If this turns out to be a success, I will update with a follow-up with a compiled list generated from all of the answers. Thanks for the assistance and contributing! UPDATE I have been using the Kindle DX a lot now for technical books. Check out this blog post I did for high resolution photos of different material: http://www.matthewdavidwilliams.com/2009/06/12/technical-document-pdfs-on-the-kindle-dx/

  • Parallel programming, are we not learning from history again?

    I started programming because I was a hardware guy that got bored, I thought the problems being solved in the software side of things were much more interesting than those in hardware. At that time, most of the electrical buses I dealt with were serial, some moving data as fast as 1.5 megabit!! ;) Over the years these evolved into parallel buses in order to speed communication up, after all, transferring 8/16/32/64, whatever bits at a time incredibly speeds up the transfer. Well, our ability to create and detect state changes got faster and faster, to the point where we could push data so fast that interference between parallel traces or cable wires made cleaning the signal too expensive to continue, and we still got reasonable performance from serial interfaces, heck some graphics interfaces are even happening over USB for a while now. I think I'm seeing a like trend in software now, our processors were getting faster and faster, so we got good at building "serial" software. Now we've hit a speed bump in raw processor speed, so we're adding cores, or "traces" to the mix, and spending a lot of time and effort on learning how to properly use those. But I'm also seeing what I feel are advances in things like optical switching and even quantum computing that could take us far more quickly that I was expecting back to the point where "serial programming" again makes the most sense. What are your thoughts?
