@IanC that's a good idea. AWK is quite useful, occasionally works where sed doesn't. I'd also recommend once you go through sed and awk, try picking up Perl

12:42 AM

Lol, that ^

Kaz Wolfe

also he called it the wrong thing.

Mass flow sensor

A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder...

IanC

@Serg Thanks, you too!

I mean, later, when you go sleep

Seth

@Serg that is a really stupid question and assumption there. I'm sorry you have to deal with that :(

Kaz Wolfe

ask him how the car reads the PWM output of the MAF.

Serg

@Seth Meh, I'm used to it by now - it's been years like that

Lol , "You're electrical engineer, you're supposed to fix this" XD

Kaz Wolfe

12:47 AM

really, @Serg. Ask him that. He'll say something along the lines of "the OBD and auto sensors pick it up and use it to regulate intake"

but be sure to ask how the car turns the PWM output from that into something it can use to process and decide how much air to let in/out

Zacharee1

That

That is a function word used in the English language for several grammatical purposes. These include: as a complementizer/subordinating conjunction. ("He asked that she go.") ("That" is not used this way in American and Canadian English.) to introduce a restrictive relative clause ("The test that she took was hard.") In this role that may be analyzed either as a relative pronoun or as a conjunction as in the first case; see English relative clauses: That a relativizer instead of relative pronoun. (In American and Canadian English, "that" is only used in this way if the verb could affect the...

Q: What is the key advantage of using Ubuntu OS

I would like to know what is the key advantage Ubuntu offers over systems like Windows and MacOS. Which is the official copy of Ubuntu. Is there support and how much does Ubuntu cost.

ubuntu-advantage

Byte Commander

12:48 PM

@MarkYisri can we please reopen that for a moment? I was just about to post a complete answer.

Zacharee1

@ByteCommander ask a mod

Byte Commander

1:11 PM

Although the question about Ubuntu's key advantages is very subjective, I'll try to name a few points. The list can of course not be complete and not everybody might agree on every point, but it's a start:

- free, open.source operating system and standard software
- huge central software repository with checked and verified software
- PPAs (private package archives) that allows every developer to provide packages for Ubuntu in an easy and user-friendly way
- freedom to also install software from external sources (although not recommended for security reasons)

^^ would be the answer I wanted to post to the closed question above. Is it good enough to reopen it for a minute? @jokerdino

Rinzwind

1:21 PM

- being free and open source is a philosophy; not perse an advantage.

Byte Commander

how can it be a disadvantage?

of course it's good.

Rinzwind

if I am a malicious person I can read the software, find an exploit and abuse it.
When it is closed source I 1st need to bypass the compiled software

Byte Commander

But there will also be a benevolent person reading it as well, finding the exploit and fixing it.

Rinzwind

(naming the openssl debacle as an example)

@ByteCommander openssl... it took how long to find it again?

:-)

Byte Commander

You can modify the source code and compile a customized version yourself.

Clear advantage.

Rinzwind

1:41 PM

... and then distribute it That last one is not allowed with Windows and MacOS ;-)

for educational purposes you can strip both windows and mac os.

Zacharee1

@Rinzwind how long did it take for hackers to find and use it?

Rinzwind

@Zacharee1 we do not know. That hack left ZERO traces.

that's the whole problem ...

there is a new law in the Netherlands: if I have data on my system and that system gets compromized I have to inform every person I keep personal data from. So if I have a list of names, adresses, emails, password or things similar ... I am screwed if I find out someone had access to it that should not have access to it.

Byte Commander

So you better not find out, eh?

Rinzwind

1:56 PM

yeah :X

well I took the other route: I remove everything on my system D:

by the way: they also included passwords in that (so VPNs saved passwords are out too :**( )

@KazWolfe Radiation per se isn't harmful. Infrared isn't harmful, unless you stare directly into a high-energy beam weapon. Ultra-violet isn't harmful, unless you stay in the sun for too long, microwave radiation isn't bad unless you stick your hand inside a microwave oven for more then a few seconds at 1 KiloWatt etc...

Ionising radiation is bad for you: don't eat Plutonium...

(It's not only highly energetic, it's poisonous too...)

You might get away with eating Uranium, unless you do it daily...

good afternoon!

IanC

how are you doing @RobotHumans?

RobotHumans

@IanC well-ish. a little in limbo right now and sorting some things out, but doing better than i was. you?

IanC

@RobotHumans all good, trying to rest from yesterday, guess I'll take the day to finally code a bit :)

RobotHumans

6:52 PM

@IanC Yeah. I got some writing done recently. Now I'm tweaking that pandastalib library thing I was working on to fix some bugs and add a feature or two.

IanC

@RobotHumans pandastalib? what is it about?

RobotHumans

@IanC it's a library to bulk precompute stock indicators etc as provided by talib by just pushing a button right now. the bug is I don't close some subprocesses when they run out of tasks and the feature is adding a new precompute and normalilzing the data to -50 to 50 regardless of type (price % movement -1:1 -100:100 etc)

IanC

@RobotHumans I'm terrible with economics, but sounds complicated :p

RobotHumans

@IanC not really complicated. it's honestly mostly glue code now. most of the hard math was already done by talib.

the idea ultimately is to normalize the data, restrict the sample sets to things that are results from "stock strategy" parameters, then feed it to a pybrain feedback learning simulation to try and train strategy specific bots that are more accurate than hoomans.

IanC

@RobotHumans your idea is to use it to automate your investments?

RobotHumans

7:04 PM

@IanC not exactly. to give me another red or green light. might reach automation eventually, but I'ld settle for keeping a human in the mix

IanC

@RobotHumans nice, what programming language are you using?

RobotHumans

python

@IanC the thinking is, no i'm not trying to build a robot to beat the market. i'm trying to take human strategies and let robots fine tune them.

@Serg - the hoodie backwards is also a popcorn bucket built in to your shirt

IanC

@RobotHumans that's nice, I think it's better if you keep it from becoming completely automated, specially when it's your hard earned money at play :)

RobotHumans

@IanC Yes. Remember that flash crash around 2000 b/c of bunch of big trading house bots decided the market was shit and it was time to sell all at the same time?

Market closed, and there was a government mandated "do-over"

There's one more trick I'm using, but I'm not entirely sure I should talk about that one. If it works out \o/

IanC

@RobotHumans I didn't remember that, but complete automation is ignoring one of the defensive programming principles, of assuming bugs will show eventually
