This video: Shows 3ds.hacks.guide site.
Me, with a hacked 3ds: I've been there…
Tea makes mine work
Was I the only one who kept hearing phone sounds
i think someone hacked my battery firmware as when it reaches 25% my pc completely turns off and cant turn it back on until i plug it to a power source. any idea how to fix it?
i dont think LEDs need firmware
Hey guys, get it?
hard ware firm ware and soft ware. hardware is physical, software isn't and firmware is in-between, just like firm sits in between soft and hard
0:19 is Python, right?
He does get a lot of Samsung messages in this video
I have been watching you earthlings and know the fortune 500 companies Always remove their private pieces of firmware before sending the machines back to the factory for repair. Like special protocols or whatever. Also some memories can be wiped by ultraviolet rays or electro-pulses so in the event of like nuclear war this is most likely why the machines will be useless.
Electronics run on magic smoke. As soon as you let out the magic smoke out the electronics stop working!
so is everyone gonna ignore what just happened at 2:45
i heard the phone message
Pretty sure lightbulbs don't need firmware or any type of ware for that matter. Unless they're smart bulbs anyways.
As someone who was a firmware engineer for a few years, I would say that this is mostly correct, but saying that there are no APIs when writing firmware is misleading and makes us sound like some kind of gods. Typically chips release middleware drivers written in C, as well as startup code written in assembly, so that firmware engineers jobs really just have to do with controlling the logical flow of the processor in C. In some cases a firmware engineer will ever be handed over a chip that basically already has a kernel, like Amazon’s FreeRTOS. However, if you work in some safety intensive arena like med devices, aviation, or nuclear, then you likely will rewrite most of these drivers and kernels yourself in order to ensure that the chip will not hang and to ensure that specific requirements will work every time no matter what. You also do this to add error traceback and logging, encryption and bootloading/updating capability, which is why many chips don’t have these things. They take a little extra work and maintenance to get them right. You can’t just use STMcube (a graphical programming language for firmware, to exemplify how simple it can get) to do some of those things. I’ll also plug that it is much more difficult to program firmware open source, because gcc provides limited support cross-platform compiling for all of the new chipsets coming out all of the time, and most of the middleware and startup code comes packaged to be used in a paid cross-platform IDE rather than eclipse or barebones gcc with make files. Most of the difficulty that a firmware engineer faces is probably just in setting up the IDE environment to cross-compile correctly, and making sure that this IDE setup is maintainable by future engineers, and not losing track of all of the physical things that you need to maintain the code since it can’t all be put into a docker setup or a saved conda/pip environment.
2:44 Linus caught using Samsung smartphone
Linus Shaved
Is your phone ringing
This video is really great
Does the T2 chip in MacBook pros qualify as firmware?
His phone rang @2:45. Stay professional Linus.
I imagined a kind of this when wasnt know about this and i called it midware, lol
Was that Notification sound linus pocket ?
Firmly aware = Firmware.
Even though I know it's coming, somehow I'm still surprised by some of LInus' abrupt segues into sponsor spots.
At 1:13 someone's phone was going off. I was only able to hear it using my headphones.
1:15 phone go off?
Great video.
Firmware is really important, and it is really "deep".
Meaning, a bad firmware may brick your device.
I think it was relevant to mention MD5 in this video – which is a method usually used to verify the integrity of a firmware file.
2:46 Someone was really sloppy that day!
Firmware doesn't sit on SSD's?
Firmware is also the word usually used to describe what goes on FPGAs. To the untrained eye, it looks like software, but it's actually describing hardware. Not confusing at all.
Machine code anyone?
Does the code in an arduino count as firmware?
Nooooo. The beard is gone. Safe day. Homie looked dope as hell. Beardgang. Hahah.
