The Woes of Windows Vista/7 Mapped Network Drives

Posted on by Mahmoud Al-Qudsi

One of the biggest, bestest, and most-hyped features of Windows Vista (according to Microsoft, that is) was the brand spanking new TCP/IP networking stack. Ask us, it sucks. Network performance hasn’t improved any over the ancient stack used in XP (nor should it – it’s not like there’s anything new in IPv4) though it does add better IPv6 support out-of-the-box and ships with some even more functionality in Windows 7. But more importantly, Microsoft threw out decades of testing and quality assurance work on the existing Networking Stack and replaced it with something rather questionable.

We’ll be following up some more on this topic from a technical side later in another article, but for now, an example that most of you are sure to have come across if you’ve ever tried to map network drives before:

This popup is shown at system startup if you have any mapped network drives to UNC shares which are not protected with a username and password. If you map a network destination that does require authentication, Windows will map the drive OK. To further complicate matters: this message is shown only when you startup from a cold boot! If you restart your PC (vs shutdown and powerup), it won’t appear.

Resolving the issue is straight-forward enough: just double-click on the network drive in My Computer and it’ll automatically, instantly, and silently connect. Which makes one wonder why Windows couldn’t connect in the first place.

Good question.

On the matter of Firefox and memory leaks…

Posted on by Mahmoud Al-Qudsi

Recently our original article/rant on Firefox’s legendary memory abuse has seen an increase in comments and views; and I had intended to post the following comment in light of the article’s rebirth and the ensuing discussions in the comments.

The reply turned out to be longer than I’d originally intended, so here it is as its own post.

I’ll try to be as objective as possible in this reply:

The most important thing for frustrated end users to keep in mind is that Mozilla/Firefox cannot be held responsible for cases where incorrectly written plugins and/or extensions cause Firefox to abuse system memory – that’s the trade-off between empowering developers and keeping the code squeaky clean.

Most of the cases reported are indeed caused by one or more extensions or plugins gone awry, doing something they shouldn’t be doing, or something they don’t know how to do properly. Some of the most popular plugins for Firefox are notorious for their memory leaks; but few users realize just how dangerous they can be, and that the Firefox devs cannot really do anything about it.

At the same time, there can be no doubt that Firefox has some memory leaks in the codebase itself. They’re clearly not easily reproducible and they don’t happen very readily nor often enough because the developers have clearly spared no effort in their attempts to address this problem for once and for all. But they’re there, nevertheless.

Shipping Seven is a Fraud.

Posted on by NeoSmart Technologies

A blog titled Shipping Seven has gotten a lot of traffic recently for their article about Windows 7 and the MinWin kernel – namely, how they’re actually one and the same. The argument offered by “Soma” is that Windows Vista’s kernel (which is what Windows 7 will be built on) is MinWin ad that it’s already on every Vista desktop out there.

Whether or not MinWin is the very same kernel that went into Vista or not is officially unknown at the moment; but what we do know is that Shipping Seven is either one huge fake, or else that the Windows core programmers at Microsoft are so stupid that they don’t know the first thing about coding, kernels, operating systems and compilers.

The post at Shipping Seven is littered from beginning to end with fallacies, lies, and incorrect deductions that anyone with even the most basic coding skills would know better than to ever post, especially not when attempting to pass it off as the work of some of the more talented coders out there.

Programmers Should Trust Their Instincts

Posted on by Mahmoud Al-Qudsi

People are either cut out to be programmers or they’re not. How to know, what to do if you’re not, and where to go from there is a huge issue and not the subject of discussion. But one of the signs of a good programmer is good programming instincts. The right instincts can save hours of work and provide creative solutions to even the most difficult problems; and “gut feelings” in programming are not something you should ignore lightly.

One of the first thing Computer Science teachers drill into the heads of their students is that it’s important to map everything out beforehand. Design the algorithm. Draw the UML diagrams. Decide the entire flow of data and the relationships between everything before you even touch the IDE. While this is integral advice for anything above a small-complexity project, there is an exception: if you have a gut feeling, follow it.

For instance, the other day I sat down to write a simulator for a MIPS datacache, with different replacement policies. “Ideally,” the planning procedure would have involved designing the sequence diagram, a flowchart detailing the method used by the cache to determine expired entries, and generally-speaking a lot of time down the hole just visualizing what happens beforehand.

Want UAC-Free iReboot? You got it: iReboot 1.1 released!

Posted on by NeoSmart Technologies

Back in August of 2007, NeoSmart Technologies released iReboot 1.0 – a tiny application that sits quietly and unobtrusively in the taskbar and is used to select which OS you’d like to reboot into.

iReboot isn’t by any means a major application, but it’s gathered a pretty strong following over the months, mostly by people interested in boosting productivity (or increasing laziness) to the max. But there was one flaw in iReboot that made all the hard work we put into making it as unobtrusive and minimalistic as possible almost meaningless: if you had UAC enabled, iReboot will not run automatically at startup, no matter what you do.

This behavior comes as a result of the architecture that Microsoft used to secure Windows Vista, which doesn’t allow for applications requiring admin approval to run at startup. It doesn’t matter what your application does or if you absolutely trust it beyond the shadow of the doubt, Windows Vista simply won’t let an application that runs in elevated privileges mode to launch at startup – end of story.

The NeoSmart DevNet Initiative

NeoSmart Technologies is pleased to announce the logical next-step in our contributions to the tech community by the establishment of the NeoSmart DevNet project.

NeoSmart DevNet is a new effort on behalf of NST to reach out and lend a helping hand to other software developers by providing a number of tools, libraries, and frameworks that we’ve developed over the last several years to address certain commonly-encountered issues in a generic-yet-customizable manner.

Basically, DevNet is an attempt at getting software developers to spend more time on developing their applications verses worrying about the stuff that they need to get there. Unlike other developer resources on the internet, the goal of DevNet is to provide complete working subsystems and frameworks to developers, almost entirely doing away with the need for supplemental coding and code-monkey work.

For instance, the first of our DevNet projects to be released is a scriptable graphical HTTP/FTP downloader. The NeoSmart Downloader (NST Downloader) is intended to be drop-in solution for anyone looking to add the ability to download and run components from the internet to their software projects. All interfacing with the NST Downloader is done via command-line arguments, making it language-agnostic and dead-simple to use.

Microsoft’s .NET-Powered Windows Live Writer

Posted on by NeoSmart Technologies

Believe it or not, Microsoft’s Microsoft .NET LogoWindows Live Writer is important in more ways than one. To most PC users, Windows Live Writer is simply the best tool that gets the “job” done. More importantly is how “job” is defined though, because WLW does things quite well and quite thorough.

Windows Live Writer has a huge range of options and takes advantage of almost all the features and functionality available via remote blogging/XMLRPC that make it almost pointless to even enter your blog’s administration center. You can upload images and movies, set categories and keywords, specify the slug/permalink to posts, modify the post date, set passwords on posts, send trackbacks, manually create an excerpt, and even specify whether comments are or aren’t allowed on any given post – all this without leaving your desktop client.

But what most don’t know about Windows Live Writer is more what it represents than what it does: Windows Live Writer is the first full-scale consumer product to ship out of Microsoft’s camp built on the .NET Framework.

Are you Still Manually Approving Online Sales? Don’t!

Posted on by NeoSmart Technologies

The whole point of the online sales revolution, and as a direct result, the growth of companies like Amazon, eBay, and dozens of smaller sites like Newegg and ZipZoomFly, is to take advantage of the benefits brought by technology to the retail industry. These advantages include less overhead costs, fewer employees, constant availability, and instantaneous sales. So, please do tell, why is that you’re still manually verifying and validating all sales before they go out!?

This may not be too obvious when you’re selling tangible goods over the internet – after all, there is still a lot of the “human element” when it comes to packaging and shipping the product. But when you’re selling digital products, be it software, music, games, or text, you should never, ever have a human doing the verification. It’s insulting.

With presence of automated purchase validation systems, like 2Checkout and PayPal IPN available which give virtually real-time updates on the status of a transaction and let you know when you’ve received your money (or at least when it’s on its way), there is absolutely no need for a data monkey to press “OK” at the prompt. After all, what’s this data monkey know that PayPal’s IPN report hasn’t already told your system?

Proper Shell Scripting on Windows Servers with Perl

Posted on by NeoSmart Technologies

  • Fact: Shell scripting is a must for any serious IT admin managing a server. From automating backups to checking logs and keeping server performance and load in check, scripting is a must.
  • Fact: Shell scripting on Windows sucks.1
  • Fact: Shell scripting on Linux and other *nix operating systems is powerful, well-documented, and quite straight-forward.

Most people take a look at these three facts, and instantly come to a conclusion.. the wrong conclusion: you can’t properly manage a Windows server because it’s inherently lacking in the shell scripting department.

Complete .NET Portability with Wine & Mono?

Posted on by NeoSmart Technologies

Mono is the open-source version of Microsoft’s .NET Framework. It implements most of the backend framework features, but unfortunately, falls flat on its pretty little face when attempting to display the user interface – which is what desktop apps are all about.

Wine on the other-hand, is a Linux port of (major parts of) Microsoft’s Win32 library – the core dependencies of the Windows development libraries, and more importantly, the win32 interface elements. With Wine, you can run many traditional C++ win32 executables on Linux, with certain limitations.

Mono’s biggest stumbling block is the GUI and .NET programs that use P/Invoke to call native non-managed win32 dlls – Mono is a pure .NET environment, and can’t handle them. But from the description above, that’s exactly what WINE excel at… So can’t we use WINE + Mono to make just about any .NET program run on Linux fresh out of the .NET compiler?

Unfortunately, the answer is no. Back when the Mono project was first starting out, the Mono development team considered using WINE to implement the System.Windows.Forms namespace of the .NET Framework (which is practically 100% native C++ unmanaged win32 code in .NET wrappers). But they made the right choice in deciding to not take the easy way and go that route, leaving the integrity of the Mono project intact and focusing on true cross-platform user interface libraries instead (the GTK# is now the UI Library of choice for cross-platform .NET applications).
