Ever wonder how tough the M1 Abrahms tank really is?

Excerpted from Tom Clancy’s non-fiction Armored Cav: A Guided Tour of an Armored Cavalry Regiment:

The setting: Desert Storm, during General Barry McCaffrey’s 24th Mechanized Infantry Division’s run to the Euphrates River. It was raining heavily, and one M1 managed to get stuck in a mud hole and could not be extracted. With the rest of their unit moving on, the crew of the stuck tank waited for a recovery vehicle to pull them out.

Suddenly, as they were waiting, three Iraqi T-72 tanks came over a hill and charged the mud-bogged tank. One T-72 fired a high-explosive anti-tank (HEAT) round that hit the frontal turret armor of the M1, but did no damage. At this point, the crew of the M1, though still stuck, fired a 120mm armor-piercing round at the attacking tank. The round penetrated the T-72’s turret, blowing it off into the air. By this time, the second T-72 had also fired a HEAT round at the M1. That also hit the front of the turret, and did no damage. The M1 immediately dispatched this T-72 with another 120mm round.

After that, the third and now last T-72 fired a 125mm armor-piercing round at the M1 from a range of 400 meters. This only grooved the front armor plate. Seeing that continued action did not have much of a future, the crew of the last T-72 decided to run for cover. Spying a nearby sand berm, the Iraqis darted behind it, thinking they would be safe there. Back in the M1, the crew saw through the Thermal Imaging Sight (TIS) the hot plume of the T-72’s engine exhaust spewing up from behind the berm. Aiming carefully through the TIS, the M1’s crew fired a third 120mm round through the berm, into the tank, destroying it.

By this time, as you might imagine, the crewmen of the M1 were getting extremely agitated and making this fact known to anyone who would listen over the radio net. Help in the form of another M1-equipped unit arrived shortly afterwards, and they began trying to extract the stuck M1 from the mud hole. Unfortunately, the Abrams was really and truly stuck. And despite the efforts of two M88 tank-recovery vehicles, the tank would not come loose.

Ordered to abandon the stuck Abrams, the other M1s began to fire their own 120mm guns in an attempt to destroy it. The first two rounds failed to penetrate the armor of the mud-bound tank. When a third round was fired from a favorable angle, it finally penetrated the outer skin of the turret, causing the stored ammunition to detonate. But rather than destroying the M1, the blast was vented upwards through a blowout panel, and the onboard fire-suppression system snuffed out the fire before it could do any real damage to the electronic systems in the crew compartment.

By this time, further M88 recovery vehicles arrived. Along with the two earlier M88s, they finally managed to pull the tank out of the mud. Upon examination, the M1 was found to be operational, with only the sights out of alignment from the blast of the ammunition cooking off. The M1 was taken back to the divisional repair yard, where the damaged turret was removed and replaced, and the tank returned to action.

The case for boredom

The Harvard Business Review has another blog post up from Peter Bregman that I found interesting not for its denouncement of the piece’s actual subject matter, the iPad, but for the case it makes for occasionally finding the time to be bored.

Why I Returned My iPad

The brilliance of the iPad is that it’s the anytime-anywhere computer. On the subway. In the hall waiting for the elevator. In a car on the way to the airport. Any free moment becomes a potential iPad moment.

So why is this a problem? It sounds like I was super-productive. Every extra minute, I was either producing or consuming.

But something — more than just sleep, though that’s critical too — is lost in the busyness. Something too valuable to lose.

Boredom.

Being bored is a precious thing, a state of mind we should pursue. Once boredom sets in, our minds begin to wander, looking for something exciting, something interesting to land on. And that’s where creativity arises.

My best ideas come to me when I am unproductive. When I am running but not listening to my iPod. When I am sitting, doing nothing, waiting for someone. When I am lying in bed as my mind wanders before falling to sleep. These “wasted” moments, moments not filled with anything in particular, are vital.

They are the moments in which we, often unconsciously, organize our minds, make sense of our lives, and connect the dots. They’re the moments in which we talk to ourselves. And listen.

To lose those moments, to replace them with tasks and efficiency, is a mistake. What’s worse is that we don’t just lose them. We actively throw them away.

G20 Summit: Fortress Toronto

Just putting this on here for the sake of remembering how downtown “looked” during this once in a lifetime summit here in Toronto. All hysteria aside, not much is really going on in the city. A couple of police cars were torched at Bay & King. Have yet to see a police officer utter a single word to a protestor.

Tommy Ton does men’s street style during European Fashion Week

Street style photoblogging is by now a popular method of understanding practical fashion trends – just as long as the people you’re shooting are the right people. GQ has a slideshow of the right people as taken by Tommy Ton during European Fashion Week on the streets of Florence, Italy.

How to remove the spyware program “AV Security Center”

While sitting in on a Microsoft TechEd 2010 conference on botnets and malware, I managed to get infected through my out-of-date Java runtimes. Embarassing, right? I spent the next few hours sifting through the Web trying to find a concise set of instructions on how to remove AV Security Center (also appears as AV Security Suite and Micro AV Security Suite) without formatting my computer.

Mostly you can simply follow the directions outlined on the bleepingcompter.com forums in a thread called How to remove AV Security Suite (Uninstall Guide) – I will quote heavily from this excellent guide. However, due either to the evolving of the malware or due to the fact that I may have gotten simultaneously infected with more than one thing, I had to follow additional steps as well. So here are my successful list of steps to remove AV Security Center from a Microsoft Windows XP machine. Using a program like Zonealarm Anti-ransomware is great because they are always updating their software to any new malware that might be out there now.

Microsoft TechEd 2010: Microsoft Visual Studio 2010 Tips & Tricks


Get Microsoft Silverlight

For the last seminar period of Day Two, 5:00 PM to 6:15 PM, I attended “MS Visual Studio 2010 Tips & Tricks” with presenters Dustin Campbell of Microsoft and Scott Cate of CloudDB.com.

5:00 PM: We kick off and are told not to worry about taking notes – all of the following is available at http://scottcate.com/tricks and answers will be posted to questions asked on the Twitter hashtag #DEV315.

5:04 PM: IntelliSense now filters down class names for “new” declarations in C# (already did in VS 2008 for VB.NET).

Will also filter by the capital letters you type (SR for StringReader) – “camel case”.

5:06 PM: New mode for IntelliSense called suggestion mode (Ctrl-Alt-Space). Won’t have to hit Escape to deselect autocompleted class/variable names. Now your suggestions come up but must be confirmed by pressing Tab before they get filled in. IDE remembers this setting in between loads.

5:08 PM: Windows 7 and VS 2010: Lets you pin classes, projects to start page. Also lets you right-click and remove from list. Had to do this in the registry in VS 2008.

5:10 PM: Startup modes: Can show an empty environment always, show last solution, start pages can be customized.

5:11 PM: Code editor tricks: Can right-click a class name and choose View Call Hierarchy. Not only what this class calls, but what classes call it.

5:13 PM: Shift-F12 shows all of the references in the project to a class property.

Microsoft TechEd 2010: Microsoft Visual Studio 2010 For Web Deployment


Get Microsoft Silverlight

4:15 PM: My first choice is Rm 276’s “DPR304: FAIL, Anti-Patterns and Worst Practices”, but twenty minutes before the session starts the entrance to that seminar room is already jammed with traffic. I turn around and instead enter the near-empty Rm 272, “WEB204: Microsoft Visual Studio 2010 for Web Deployment” by Vishal R. Joshi. Less laughs, but probably more applicable to my day-to-day routine.

4:20 PM: Internet access in the conference centre still doesn’t work. It’s been two or three hours now?

4:24 PM: We’re starting early! The presenter abruptly introduces himself while standing in the middle of the room, making us all search around to find him. He’s in the middle of the room.

He asks that we provide examples of what kind of setup we’ve got going, and what challenges we face with them. He picks the first person at random and forces him to speak, but after that people volunteer themselves. It runs the usual gamut of multiserver deployments with complicated XCOPY scripts. I can relate.

4:30 PM: We’re given notice to finish checking our e-mail and get ready to pay attention. Joshi plays Louis Armstrong as a sort of Emmy-wrap-up-your-speech music cue, but for writing e-mail.

4:32 PM: Room is about half full.

4:37 PM: One cup of broccoli has only 43 calories. We’re told that this talk has broccoli in it. This is our fair warning that this is a unsexy topic which Vishal will try to counter by being as cheesy as possible. Thanks!

4:40 PM: An old deployment document of Vishal’s is 52 pages long, and doesn’t even have any code in it. And it uses XCOPY. Ouch.

4:41 PM: The centre of today’s discussion: Replacing XCOPY.

Microsoft TechEd 2010: Developers Are From Mars, Testers Are From Venus

Because I missed the seminar I really wanted to attend in the earlier timeslot, I’ve parked myself right outside of Rm 349 in order to attend “DPR05-INT Developers Are from Mars, Testers Are from Venus”.

2:14 PM: I’m the second person into the room, and seat myself near the back to ensure access to a wall power outlet.

2:15 PM: The presenter of the last seminar in this room, “Microsoft Visual Studio 2010 Tips and Tricks” has a line four deep full of people wanting to ask extremely technical questions. He’s looking around in desperation wondering how he can get out of here.

2:17 PM: The crowd up front dissipates. One of the presenters of my seminar asks him how it went. He says, “Fine, just answering question after question… Slides are boring!” I tend to agree, though a seminar doesn’t strike me as the right place to ask how to solve bugs I run into at work. He wishes her to “break a leg!” and leaves in a hurry.

2:20 PM: It’s quiet now, so I continue to work on turning my keynote scribbles into something approaching readable.

2:21 PM: The conference hall’s Internet has been down for more than an hour now. I overhear that supposedly a main trunk is down and it’s actually an issue affecting the entire city.

2:40 PM: The seminar room is half full; maybe testing isn’t a popular topic. We’re told we’ll start in 5 minutes.

Microsoft TechEd 2010 Keynote @ New Orleans, Day One

8:35 AM: I head into Hall F for the the Microsoft TechEd 2010 keynote by (a name previously unknown to me) Bob Muglia, President of Server and Tools Business for Microsoft. A coworker beeps me to let me know the doors have been opened at 8:30 AM, so I walk a long mile guided by dozens of red-shirted Microsoft ushers (enforcers?) to the far right side.

8:40 AM: Almost as soon as I take a seat, the band that’s been quietly setting up on the stage kicks into their first song at full volume and startles everyone. It’s a nine-man band composed of all your expected instruments: Guitar, saxophone, drums, trumpet, chainmail-washboard shirt. I fail to catch the name of the band on any of the screens and also forget the name when it’s mentioned at the presentation’s close by Bob Muglia. Sorry guys.

8:45 AM: The lead singer seems to be wearing a sort of chainmail shirt which he also plays as an instrument (the washboard). How great would this have been back in Ye Olde England? You could be both a minstrel and a knight. Maybe instead of being a great knight or a great minstrel you’d be mediocre at both, but the flexibility would have been enticing.

8:47 AM: The lead singer rather abruptly attempts to get the audience to sing along. We fail miserably but at least have a laugh at ourselves. My section is quickly deemed the lead singer’s favourite due to its higher than average energy level (not me, I’m typing, but Dmitri yells loudly at one point).
