A simple microcontroler (like Microchip's PIC16xxx) has FLASH memory and has access to it at the same speed as RAM. Running at clocks from 20 to 40MHz.
Not to mention ARM's and other similar devices who work at much more speed... smarphones maybe ?
Access to flash may be crippled by interface in the case you mention.
I had the same problem, but in the cars I used, I found it easier to stick my left foot on the leftmost part where there was something similar to a fixed pedal made of plastic out of the side of the car, just to leave your foot rest there. When I had the instinct of activating the clutch, I just pushed there with no fatal consequences.
I think this is probably an important rule that you cannot break in international numbering conventions (someone better informed could enlighten us). I say this because 10 or 15 years ago there was a huge numbering restructuration (due to increasing mobile numbers) to allocate a special numbering for mobiles (cellulars ?), and when it was done I remember several experts arguing to follow the international numbering rules to avoid this overlapping.
So if you have 911 for an emergency call, you won't be able to have any 911xxx number afterwards. It's not a big issue, just to confirm 911 at least has one clear numbering in conflict here in Europe.
I would be interesting to know if there is any on the other way (112).
Ampers measures electric current flow. Volts mesaures voltage potencial.
In some cases there is a relationship (by the means of an ideal source and an ideal resistor), but "Amps is dependent on voltage only in a specific case".
Just add that this is an economical disaster, but more important a security disaster, imagine someone near the fires looking for the cabling when they did the test.
Agree on this. This is a test procedure with firing currents instead of test currents.
I designed the electrical and sofware part of a Firing System, and the matches needed much more than 100mA to fire, the 5mA seems on the test range.
In our case our circuit tested the whole show in just a few seconds like this (each match every 0.05 or 0.1s). So if firing current (>>100mA) was applied a faulty test would do this.
But because of this (this is also an economical disaster for the company), the test procedure is hardware forced with low current, with redundant circuits that block that disable the firing current by two or more ways by different systems, that means, that software and hardware must enable the fire.
As this fired at the three places at the same time, this seems a completely software plattform with no apparent HW securities... bad idea.
I'm an EE and we are continously developing different products.
It happens quite often to touch active parts of a circuit by accident while testing / debugging prototypes.
I am not a (by any point of view) brave/crazy EE who likes the risk of an electric shock, but in the usual work you touch active circuits everyday. You do this because you know which are active parts that harm and which are active parts that don't harm you.
There are circuits you always take good care to not put you naked hand onto: -It's quite clear that 230VAC (standard in Europe) electric shock in your hands is quite painful, to me it's not harmful but really disgusting ( YMMV ) -On shock at 125VAC it's noticeable but it's clearly less painful than 230VAC. -I've never had the "pleasure" to be shocked with 400VAC, and I prefer to not experiment it. What I can assure is that a contact with a 350VDC charged capacitor is quite disgusting, it even can make minor superficial burns.
Then there are the clear safe circuits you know you can touch without risk (and while debugging I can assure you it's quite often to do): -5VDC and lower voltage circuits to power supply IC's. -12VDC or AC or 24VDC or AC. DC is typical for relays, AC is typical for electrovalves. -30VDC is the legal limit for circuits surrounding a short distance in a swimming pool, so it's quite safe to touch in a dry environment.
Then there is the middle zone where you never know:
-48VDC circuits (some communications power supplies) I've recently completed a design that had this power supply and haven't noticed anything
-75VAC circuits (ringing phone lines) It's easy to have a bad experience manipulating the phone line while someone rings you. Just a small shock, not very painful.
So in my experience the zone between the 50V and 60VDC is where it begins to be noticeable. Of course 48VAC will be noticeable as the peaks will be 1.41 over 48V (67.68V peak).
Don't take this as a guaranteed guide, but it's worth my 20 year of experience in electronic circuits design and manufacturing.
I can assure you 12VDC are more secure for a human body. You can touch 12VDC without any problem, just please don't touch it with your tonge and between the two poles. The voltage needed to make damage to the body it's in the 50V to 60V by my experience.
Then it's the same it happens with email. Only one email fellow with a trojan makes you receive a lot of Spam.
It's time to educate people you talk to the same way you try when you are talking with email fellows.
I understand what you say, but installing an app out of official Marketplace cannot be seen as an accidental trojan infection (at least in my personal experience), you have to disable a couple of settings to be able to do so in a stock phone, so when someone does this it really wants that bogus app, then we have arrived at a social issue.
But I ask the same I asked in the last Android trojan discussion here:
- On Android the app was installed from a bogus marketplace, so if I do not change this default android restriction (you are not able to install apps out of official marketplace without explicitly changing configuration with a beautiful warning), how is this a problem to a "normal" (maybe security conscious) user ? When you give a certain degree of freedom in a device, uncautious users are able to make this things even after several warnings against this.
Here in Spain we have managed to build (don't ask me how) the largest high speed rail networks on Europe (2600km, aprox. 1600miles).
It has been a total success, but it should be noted that:
-In Spain AVE (Alta Velocidad Española, Spanish High Speed) was developed in entirely in a new network with always two new independent rails. This was in part due to a strange rail size in Spain, that is different from the rest of Europe, so it was a logical step to start the new network with the European standard. -The network was started in 1992 and it has taken until last year 2010, to generate profits. This is due to the fact that in 2008 the finally completed the Barcelona-Madrid link which connects the two main cities in the country (600Km apart).
There's one thing that is important to think about: are USA main cities links as close as Spanish's of French's ?
The main reason it is such a success is that Barcelona/Madrid link is at the distance where train versus plane takes roughly the same time:
Barcelona/Madrid: AVE: 2h 38m Plane: 55m
Why do I say it takes the same time. By experience.
Train: You take the train in the centre of Barcelona (where you arrive by Bus, underground or whatever) and go to the centre of Madrid in exactly 2h38m. You can seat in a reasonable space with your computer, cell phone, wifi, you can walk around, even you can go to the bar/restaurant.
Plane: You take whatever transport from the centre to the Barcelona airport (give it optimal 30m). Get into your plane, this includes check-in, security scanning, boarding etc... and avoid anything suspicious in your bag, minimum 30m. Plane taxi 10m minimum. Flight to Madrid 55m standard. With usual restrictions on planes. Plane taxi to finger 10m minimum. Get out of airport 10m minimum (it is the time you take to get out of the airport, it's big, with only handbag luggage). You take whatever transport from Madrid airport to the centre (give it optimal 30m).
If you sum all the times you see a lot of "minimum" notes, so it is very easy to make this longer, but overall it takes 1h55m inside of the airport and 1h outside of the airport.
You can say the difference in time is very little but the flight travel is an authentic gymkhana (not sure if this is correct in english, maybe adventure ?) to get this time (2h55m) done, full of stress and push here and run on the airport corridors . In the train the 2h38m is a really comfortable and pleasant voyage, were you can work (full cell coverage at standard rates). No rushes, no small seats even in tourist class. Nothing to compare with a plane experience.
Last minute comments: Current train average speeds are only 300km/h, it is expected to achieve 350km/h in a few years. No plans to get 400km/h yet. If we think in energy costs the train wins in economy.
The main question is: does this fit with the city distances in USA ?
Slashdot Mirror
Well it's the definition of the "Real Academia Española", so you were correct.
But I can assure you that it isn't of common use, probably a local or ancient use.
Not in Spain (Europe), I don't recognize the word.
Maybe in America ... I'm not aware of this, if anyone knows: please enlighten us ;-)

In fact... if you make 911 the emergency number in Spain we won't be able to dial to the 10% of fixed lines in Madrid in Spain.
91xxxxxxx is how all home lines in Madrid province begin with.
Sorry but no.

I agree with you on this.
The people I worked for, would never be near the fireworks during test procedures.

I know you where joking, but I thought you would like the reading (although not so amazing as you could have imagined).
Anyway sorry for my bad English.

- Is the issue Similar in the symbian OS ?
Has anybody seen if those bogus apps are in the official Android Market or are in bogus Markets ? I must have missed that from the summary.
I mean in those were Android says a warning message like: do not install anything from non-official Market who you don't whole-fully trust.
