Space-wrecks: Elon's prototype Moon ferry Starship blows its top during fuel tank test

Guido Brunetti

A (not official) source said that a communication problem between pumps and sensors led to a massive overpressurization. So the tank/hull construction likely wasn't at fault.

Windows is now built on Git, but Microsoft has found some bottlenecks

Guido Brunetti

Re: SourceSafe

SourceSafe had the same issue as Access: Not being a real server, so relying on the network file system to handle multi-user concurrency - bad idea.

TFS on the other hand uses a proper SQL Server Database to store things. It has absolutely nothing to do with VSS anymore and in fact Git is now the preferred source control system in TFS. All in all TFS is probably the best and fastest developing ALM tool around today.

What's up, Zuck? FTC to probe Facebook for WhatsApp phone number mega-slurp

Guido Brunetti

Re: Why the deafening silence from the EU on this?

There is no silence at all. The EU commissioner for competition, Margrethe Vestager, is already looking into it and "talking to Facebook". Also, at least the German antitrust agency ("Bindeskartellamt") is doing an investigation of the issue, saying, "we have to look in the Facebook engine room to understand the implications for competition".

Even if this would work (big if), it just takes the rocket straight up. But that is just the easy part of a rocket launch. Now you have to accelerate to 17.000 mph *sideways* to get it into orbit.

Re: Why use the military?

The single largest holder of official federal U.S. debt is the Federal Reserve Bank - a private institution with strong ties to "old money", followed by China, Japan and Brazil.

Right now, China and the U.S. depend on each other, both economically and financially. But the Chinese work on both fronts to make these ties severable. And they pour lots of money in military technology to actually survive the eventual severance and become the next superpower.

And no, it wasn't actually faster than the gas fill up, if you take into account that the Audi got more than double the range out of it, but it was close enough to count.

Powershell terminal sucks. Is there a better choice?

Guido Brunetti

Re: Why not use jpsoft / bash

Because PowerShell (incl. ISE) is installed on every recent Windows system by default and bash isn't :-)

Because on a recent Windows Server you can script every single server function with it, which you can't do with any other shell.

Because a lot of server software nowadays comes with it's own PowerShell provider plug-in, which makes scripting this component (Exchange, SQL Server, ...) a whole lot easier.

Guido Brunetti
Thumb Up

Just use Powershell ISE

Installed automatically with Powershell 2.0 and upwards.


Coming in 2014: Scary super-soldier exoskeleton suits from the US military

Re: and I'll say it again....

Because controlling even a single droid like that requires serious wireless bandwidth. Did you ever try to operate a W-LAN-like connection over a few miles with a mobile target in combat conditions, especially when the opposition can just setup a 1 kw broadband noise emitter.

It's one thing to operate flying observation drones that way cause flying is actually quite simple once you get the hang of it. Operating on the ground is much more complex. More obstacles, hindering your vision, your movement and blocking your radio connection. Then there is the issue of light speed. Controlling a drone in Pakistan from U.S. with one or two seconds latency may be OK, but try playing counterstrike with a 1 sec latency. You just get your ass handed to you - every single time.

Our week with Soylent: Don't chuck out your vintage food quite yet

Guido Brunetti

Nothing new, really

As the soylent guy I was uncomfortable especially with the lunch options at most of my changing work locations (too much fast food, or too low quality of the food). However, what he found out through (self)experimantation has long been found out by people who need to feed patients that cannot eat through normal means. And they produce well-tasting spin-offs for non-patients, too.

I'm a bit overweight, so I also wanted a method to control my calory input. Just keep it a little under what I actually consume, to promote a slow, long term loss of weight. Worked pretty well over the last year, I'm losing about a kilogram per month.

So this is what my routine on a work day looks like (on weekends I just eat normally, my wife cooks then for both of us):

I start the day with a chocolate croissant from a dealer at the train station (around 400 kcal) at 07:15 to lighten up my morning mood :-). At around 10:00 when I start to feel light hunger, I down a 200ml can of Fresubin 2kcal chocolate flavoured energy drink, giving me another 400 kcal. This Fresubin stuff (just my personal preferred choice for taste reasons) is what the nutritionists call "fully balanced" meaning that with three cans of that all my vitamins, minerals etc. are fully covered.

Lunch around 12:30 is a wholemeal bun with some spread (tuna, egg, or whatever tickles my fancy, i try to avoid the high kcal ones), an apple and a carrot - another 400kcal. In the afternoon another 400kcal can, then one more in the evening and that's it, apart from 1-2l of sparkling water over the day. 2000kcal input. At my height, weight and sport level (2-4 hours of light sport during the week), my daily need is around 2500. I sometimes cheat with a little treat or a nonalcoholic beer after sports, but in general it's working in the right direction (as opposed to working in the wrong direction when I didn't control my calory intake).

Bradley certainly has the looks of a PFY (PFC is probably just a typo). And while Julian certainly is viewed as BOfH by the Amerikanskys, I doubt his qualification in that role. Which makes one wonder where the real BOfH hides?

Incoming comet will probably miss Mars, says NASA

Guido Brunetti

Re: "NASA's current prediction of the comet's path."

The influence of Mars on the trajectory depends partly on the relative speed of the comet. The higher speed the less influence since the time spent in the stronger parts of Mars gravity field is very low. At well over 100,000 miles per hour the comet isn't staying long enough to produce a big, visible bend in the trajectory curve. The big curve in Nasas graphic comes from the sun, not from Mars.

Plugging my Computer into the central heating? What should that be good for?

In Winter (when I use the central heating), my computer heats my room just fine. Every Watt of electricity that goes in comes out again as heat plus some shifted bits in my SSD. If that heating isn't sufficient, my room thermostat kicks in hot water from the central heating, so presto, problem already solved.

So why would I reroute the computer heat through the central heating and then into my room through hot water, when the direct path works just fine?

Security audit finds dev outsourced his job to China to goof off at work

Guido Brunetti

Re: The only reason anyone is angry at Bob...

Doesn't matter. They probably put in some skilled people from their foreign intelligence department, not from the company itself. Getting an authorized VPN-channel into a critical infrastructure, getting all sorts of system specs, getting to write code incorporated into these systems and then even getting paid for it must have been a no-brainer for them.

On the other hand, they probably would have been smart enough to use a U.S.-proxy then. But now that the contractor is out of business with this client, they probably sell all the information they gathered to the highest (chinese) bidder.

Fusion-io demos billion IOPS server config

Guido Brunetti


At this point they shouldn't refer to these things as "Drives" any more, because there is little resemblance to the original meaning of that word.

What about "PRAM" (persistent RAM) as opposed to "DRAM". Technologically it is much closer to DRAM than to harddrives anyway.

LOHAN fires up sizzling thruster

Guido Brunetti

Thrust measurement

What is the weight of the fuel? You have to add that to the measured thrust over time to get the real thrust. Near the end the real thrust would be the measured weight on the scale plus the weight of the already burned fuel since the initial "0" measurement included the fuel weight.

So if your fuel weight was, say, 500g, the peak thrust would actually have been measured at roundabout 1900 grams near the end.

Fukushima scaremongers becoming increasingly desperate

Guido Brunetti


OK, let's do the math.

Here is the measurements of radiation in the water sample taken, according to Tepco:


The dominant radiation comes from Ce144 with 2.2 million decays per second per cm³. This emits a (rather weak) electron (beta decay) on its way to Pr144. That element has a half life in the seconds range and thus goes almost immediately into another beta decay to Nd144, this time with a very strong output (~ 3 MeV), which gives it a high penetration range (> 1 cm in water/tissue, up to 15m in air).

Organ exposures and effective exposures are both measured in Sievert. As I said, the total dose

was significantly less, "more than 170 mSv", according to Tepco, but since most of that dose occured at the feet through direct contact with the contaminated water, it creates an organ equivalent dose well in the single digit Sievert range. These workers may or may not get radiation sickness, but their cancer risk is already orders of magnitude raised.

BTW: The existence of relatively large amounts of Ce144 in the water confirms a significant core meltdown. One cm³ (!) of that water can contaminate a thousand litres of ground water with over 22.000 Bq/kg, which is way over any safety limit. And with a half-life of 284 days that problem will stay for a while.

Guido Brunetti

Wrong base

The 10.000 times factor is not related to the background radiation but to the normal level of water in a running reactor core!

The total dose taken by these men at the feet-level was 5-6 Sievert! Total dose was less of course, but that's still pretty much and something like a "light sunburn". Not at all.

Guido Brunetti

The True Cost of Desktop Support

Guido Brunetti

Still missing the mark

There is an iceberg of costs that isn't even mentioned here: Time wasted by employees to work around artificial restricitions.

You want to take home some work but can't, because IT has disabled your USB-Drive? Now you have to zip/crpyt it and send it through email.

You need to find out a certain parameter of your SQL-Server but don't even have the reading rights necessary? Go off, find an admin, file a lawsuit or just ignore the whole matter until the server blows up.

You can drive down the support calls to zero by not allowing your users to do *anything*, but your business will suffer. Throughput is what matters, not cost!

But because the untold wasted minutes for circumventing IT can't be measured, you just ignore the matter altogether. The result can be watched in almost every larger organisation: Loss of intrinsic motivation, loss of throughput (everything seems to take ages), loss of customers. The response: Cost reductions of course!

Microsoft's .NET at ten: big hits, strange misses

Guido Brunetti

3.5 includes 2.0

Doesn't make sense. 3.5 is a superset of 2.0 and uses the same runtime. Basically 3.5 is just 2.0 plus some additional framework librarys and a new compiler.

Different runtimes exist for .NET 1.1 and 4.0. All of these can be installed on the same machine.

"In the event of a drop in cabin pressure, you may find your nether regions are shrinking...."

Not so! In fact, the reverse will be true. That's why such things as certain feature-enhancing pumps are sold in erotic stores all over the world.

So a better announcement would be: "In case of a pressure drop you will find that certain oppurtunities offer themselves to you - or should I say "arise"?. Use them quickly and we will guarantee you a happy landing."

Sparks fly over electric shock dealing Dell laptop

Guido Brunetti

I had this, too ...

... on my Dell Inspirion 8600.

It's not noticeable during normal work, but when I was on the beautiful island of La Palma in December, I noticed a tingling sensation when touching the frame of the screen while plugged-in. The strongest "shock" was touching the shielding of the svga-socket while blindly searching for the usb-slot on the backside. It was quite uncomfortable, but not painful as such.

At this time I was barefoot on the ceramic tiles in the house. Not surprinsingly, it went away when I put my (cork-soled) sandals on (though I thought, the ceramic tiles shouls be pretty good insulators, too).

At that time I thought that maybe some strange wiring in the house was responsible for it, because before and after that holiday I never experienced that sensation again.
