👨‍💻 I am interested in wired & radio communication, DSP, (embedded) software dev & engineering, FOSS, reverse engineering, IT security, space, programmable and non-programmable bricks, old and new computer technology, robots, machine embroidery & other things. Living in 🇩🇪. Speaking 🇩🇪/🇬🇧/💻 and understanding a little bit of 🇫🇷.

I found a very nice printable addon for my #bicycle 😁☺️ #citybiking

@lethalbit Here you go. I just remembered I put a function like that into the gerbonara cli.

This is the hardest message I have ever written.

Does anyone in have a lead on a company that would be willing to sponsor a web development technical lead?

I am open to most Euro, Japan, and Oceania.

My German is bad. My Japanese is a bit better. I would love to get better.

It seems like things are going to be no longer safe for my family.

Help me.

Please boost. 🙇

Hey, if you're interested in doing signal processing on embedded devices using OpenEmbedded, and maybe shy away from corporate pricing for OE workshops:

@gnuradio #GRCon25 features a workshop "GNU Radio on Embedded SDRs" by Philip Balister @Crofton (of OE fame) and Toby Flynn (of RedWire Technologies).
There's week/1day tickets available & if you're into SDR, #GPU-accelerated DSP, satellite comms, radio astronomy, physics with SDR, DSP architecture, radio metrology, …, it's a really nice conf.

When I was a kid, I sometimes wondered how a sprinkler "knew" how to change directions without being powered with electronics. I think it wasn't until I was in my late 30s that I came across this GIF and I realized how insanely genius a simple sprinkler really is.

EDIT: Some people have kindly pointed out that this GIF was in fact from a demonstration on how different gears function and not from an actual sprinkler as I had originally led to believe. Other people have been assholes about it.

lT security 101: Don't leave your company laptop with authentication smart card inserted, applications open and without screensaver at your seat when using the lavatories on a train. Unbelivable...

Maximilian Golla Jun 30

@LaF0rge Way way crazier is this computer mouse 😅

Allgeier Jun 30

@m33x
That immediately caught my eye too, I suspect the picture is fake.
@LaF0rge

Ted Mielczarek Jun 30

@allgeier @m33x @LaF0rge its a cheap USB mouse, why does that make you think "fake"?

Allgeier Jun 30

@tedmielczarek
In the picture, I simply don't see any room to use the thing. And the user is unlikely to use it on the keyboard as a base, no matter how expensive the mouse is.
@m33x @LaF0rge

@allgeier I've done this before, there's enough room for a little mousing action on most laptops on the palm rest to the right of the trackpad. It probably just ended up on the keyboard when the owner got up so it wouldn't fall.

Juli Jane Jun 30

@allgeier @tedmielczarek @m33x @LaF0rge I always use an external mouse in the train (a bluetooth one, though), as I can't work with the stupid touchpad. The trick is to move the laptop a bit to the side so that it is not fully on the table, then there is just enough space for the mouse. it makes sense that while going to the toilet the person moved it fully on the table (I just would not leave my Laptop at all, though).

So calling it fake just for that is really a unreasonable assumption.

John Lusk Jun 30

@julijane @allgeier @tedmielczarek @m33x @LaF0rge

Although... skepticism about pictures in general is to be applauded.

@allgeier @tedmielczarek @m33x @LaF0rge

Mice work pretty well on trousers too, just saying.

Damian Fajfer Jun 30

@allgeier @tedmielczarek @m33x @LaF0rge I saw plenty of people using mouses on train rides. They use the palm rest area to operate a mouse

Allgeier Jun 30

@fajfer
"On train journeys" is relative. What we see here in the picture is a flat flap attached to the front seat and folded down, the surface of which is completely taken up by the laptop. Where do you have palm rests on the laptop?
@tedmielczarek @m33x @LaF0rge

Damian Fajfer Jun 30

@allgeier @tedmielczarek @m33x @LaF0rge right and left of the touchpad is what we refer to palm rest, there's where people put their mouses

@fajfer
Now I know what you mean. Okay, they must be people who use Excel to create their CVs.

@LaF0rge or, as we say as “Businesskasper”… Monday.

Abdelkader Boui Jun 30

@vogelchr Das ist kein Businesskasper. Man achte auf die Smartcard im Laptop. @LaF0rge

1000millimeter Jun 30

@abdelkader_boui @vogelchr @LaF0rge Wenns die Firma für alle verlangt braucht auch ein Businesskasper ne Smartcard

Johannes Jun 30

@1000millimeter @abdelkader_boui @vogelchr @LaF0rge Nein, das interessante daran ist nicht, dass das eine Smart card ist, sondern nach welcher Smartcard das aussieht.

@JmbFountain Hilf uns auf die Sprünge.. ich erkenne da nichts 😅

Vorsicht, könnte ein Honeypot sein :D

Lucas Treffenstädt Jun 30

@LaF0rge have you sent an email promising cake to their whole company? That's what we do when someone leaves their workstation unlocked 😅

lobingera Jun 30

@lucas @LaF0rge my colleagues just sent an email to everyone to invite for a drink when they found an unlocked computer. The percentage of unlocked computers dropped drastically

That's what we did at a previous job: Send that promise into a specially created group "Cake News".

Stefan Offermann Jun 30

@isotopp @lucas @LaF0rge I am still waiting for an unlocked notebook to establish this group in my company.

Damn colleagues! Hitting WIN+L every time they leave their hardware... ;-)

schrotthaufen Jun 30

@lucas That’s questionable within the own company, and likely a crime if you do it on a train. @LaF0rge

TheConstructor (he/him)Jun 30

@lucas @LaF0rge at university they messed with the desktop wallpaper. We had cases where it was replaced by a screenshot of itself, then icons hidden and taskbar minimized, and cases with pictures thought to be not in the taste of the person not locking the desktop… Very few persons had this happen to them twice. Less cake, though.

thunfisch Jun 30

@LaF0rge Well, there's only honest and law-abiding people travelling in first class, so there's nothing to worry about here! /s

lobingera Jun 30

@thunfisch @LaF0rge i seriously like your sense of humor

Riku Voipio Jun 30

@thunfisch @LaF0rge This is one of the security holes the 9/11 attackers exploited.

@LaF0rge failure on layer 8, the meat space is a tough ground for IT-security. It is so hard to teach users to do the right things. There are cultural barriers between IT departments and basically the rest of their surrounding organisations.

Marcus Müller Jun 30

@daccle @LaF0rge not that I'd generally disagree, but this is quite literally equivalent to leaving a company car with company keyring on the dashboard unlocked at a highway resting area while you're taking a leak. Not hard to communicate at all.
Someone here just doesn't care.

@daccle @LaF0rge

The 8th layer should be part of the OSI model.
Do you mind if I start an internet draft? 😂

@jean_dupont @LaF0rge go for it, but I guess it is already existing

@jean_dupont @daccle @LaF0rge Layers 8 and 9 have been religion and politics for as long as I can remember. Maybe you’re looking at Layer 10.

@timoj @jean_dupont @LaF0rge then we will need a standardisation committee, since in my bubble layer 8 is and always has been the user.

@LaF0rge @daccle @jean_dupont Fine, then you can moderate the inevitable, neverending debate as to when it’s best to hold the requisite ISO standards conference in Switzerland, followed by whatever inevitable argument they’ll have with the NIST folk in Gaithersburg, provided those people still exist.

@LaF0rge Karte ziehen und kurz nen Kaffee trinken gehen.

1000millimeter Jun 30

@ccchris @LaF0rge Wieso gehen? Das Spektakel würd ich mir anschauen wollen

kamikadse Jun 30

@ccchris @LaF0rge Nimm die Kiste komplett mit und schick Karte und Workstation separat mit insgesamt einer Grußkarte ans BSI. Dann gibt‘s ne Gaudi, das sag ich dir

kamikadse Jun 30

@LaF0rge @ccchris #SINASafari #SINAZwangsbremsung

@kamikadse @ccchris na das wäre vmtl wahlweise Unterschlagung, Nötigung oder Diebstahl. Nein danke :/

kamikadse Jun 30

@ccchris @LaF0rge Wieso Nötigung?

Und für Unterschlagung und Diebstahl liegt nicht die erforderliche Zueignungsabsicht vor :p /j

DrScriptt Jun 30

@LaF0rge that’s when I do something like moving / rotating the computer. Something obvious so that they know someone did something but they have no idea what else was done.

Actual smart card. So someone else takes security more seriously than your fellow passenger.

die_christine Jun 30

@LaF0rge As I can see: It's a Lenovo with sensor for fingerprints. You can lock and unlock it within milliseconds.

@die_christine @LaF0rge Yes, but the user of the computer didn’t do that. The screen is clearly indicating the computer is not locked.

die_christine Jun 30

@stadsplanering I can see that. I only wanted to point out that locking and unlocking is so easy. I can'*t understand that he didn't do it. @LaF0rge

@die_christine @stadsplanering @LaF0rge probably not. If the previous commentors are right, then that the Laptop is a Sina Workstation that is running a custom "secure" OS.
Fingerprint is usually not supported on those. You are supposed to pull out the Smartcard which will lock the device automatically. In my opinion that is even easier than biometrics, but still doesn't help if the users don't do it.

@die_christine @stadsplanering @LaF0rge BTW since those devices are built for dealing with confidentiality material it could be even a violation of the german law to leave the laptop unlocked and unattended (if confidential material IS on the device)

@tuxflo @die_christine @LaF0rge I assume it is a violation just leaving it unlocked even if you do not handle confidential information on it at the moment. It is acting as a point of entry to the entire secure system it is connected to. 🤦‍♂️

And yes, just pulling the card out is so easy and locks it right away (had similar system on a work computer a while back).

They should also have those privacy filters installed just to limit the view of the screen.

@LaF0rge They don't care and transform every public space into the cubicle from hell. Encryption is useless with them as they spill all the beans over the air and plain old shoulder surfing and -a pair of working ears- scratch that: a half decent mic and a recording device is all you need.

@maz @LaF0rge Also people entertaining the whole train with their medical problems or relationship drama on their phone. Better than soap operas....

Christian Horn Jun 30

@LaF0rge Don't underestimate this setup of a honeypot to see what comes by..

@LaF0rge "sicher im Rechtssinne"

Alerta! Alerta!Jun 30

@LaF0rge It'd be interesting to see what happens should the smart-card suddenly be lost... 🙈

Bianca Kastl Jun 30

@LaF0rge 🤨 no worries, it’s just government grade authentication 🫣
