Well, the backend is native at least.

Yes, certainly. I will add that very soon. It is also possible to download and try yourself without paying (there is a free trial period).

I have been building an agentic code IDE (like everybody else :)). https://syntverk.com Native cross platform app coded in rust + tauri. I prefer using it to the other agentic code apps I have used. It has multi tab worktree iso

"Torvalds wrote the original code for printk, a debugging tool that can pinpoint exact moments where a process crashes" A debugging tool? I do like printk debugging but I am not sure about that description :-)

It is not related to OpenSparc. LEON is a SPARCv8 developed initially by ESA and later by swedish company Gaisler Research.

Automotive Grade Linux is pretty much a Linux distribution for infotainment units. It's not about running Linux on ECUs.

I have read this post many times and just want to say that I really like it :-). Sounds like great fun. Unfortunately not a citizen though!

You can only address one row/column at a time in a normal DDR memory. Start by reading this if you want to learn more: https://people.freebsd.org/~lstewart/articles/cpumemory.pdf In the end memory design is l

Well, on e.g. x86 you have "rep stos" instruction which pretty much amounts to memset in HW. The operation needs to be blocking otherwise you could of course do it without CPU at all (DMA). But you still have to go through the mem

I am yet to see a embedded system using Qt that is not upgradeable. And lots of embedded systems are sold to consumers. In what way was I "completely wrong"? It seems to me you were the one who was wrong and now are grasping at st

I think I'm clearly stating my assumptions. GPL3 and LGPL3 requires you to enable the user to replace the GPL/LGPL3 code on your device with the users own version of said code. It does not matter if you link statically. Now, it wo

You don't agree that you need to provide a way for your customers to replace the Qt libraries? (because that is a fact of LGPL3, read the anti tivoization clause). Do you see any possible security problems with the above? Because in re

No need for the tone. That is really easy as you say. What you seem to have overlooked are the implications of doing this. You are forced to help customers replace the Qt libraries in your product. That has quite large security/warrant

by kristoffer 7y ago
Your last sentence is a bit hard to comprehend but not paying for Qt and shipping a commercial embedded product is pretty difficult due to the anti-tivoization clauses of GPL3. I agree with parent poster that flutter is very interesting for

Ok I'll admit I'm not familiar with medical certification. I know that the so called Qt Safe Renderer for ISO26262 compliance is a bit of a joke at least. I have seen two very big Qt projects being cancelled due to Android. Not th

Most embedded tooling is free nowadays. Free software has eaten the world and will continue to do so. I will use a free UI toolkit when I can. Qt will kill itself with their current pricing model. Automotive is moving towards Android. Qt is

Reasonable? It's about $500 / month / developer with additional royalties if you are shipping devices with Qt firmware. Sure I think Qt/QML is the best UI toolkit available but this crazy pricing is driving me towards an

I don't know why they disabled ASLR, but safety critical systems (and functional safety people) tend avoid randomization...

If cell providers advertises their services as "Always 100 Mbps guaranteed" that would be a problem, but do they really? Because that is not how wireless communication works. E.g. in LTE the user is scheduled both in frequency and

by kristoffer 8y ago
Sure, I agree that you should limit ASIL certified software as much as possible. Nothing running on Linux will be certified ever. That also limits the benefits of Qt Safe Renderer. I think it is mostly a marketing thing within the automotiv

by kristoffer 8y ago
This does not really mean Qt (and/or QML) is certified. It means there is support in QtCreator for exporting certain graphics (tell tales) so that they can be rendered by Qt Safe Renderer and if that happens on a certified RTOS the sys

You’re confusing film and video. Anyway (D)SLR use phase detect autofocus in which you don’t have to figure out much at all. Mirrorless is another thing.

The author writes a long text about how this is "not as easy for an autonomous system to solve" just to make the obvious point at the end of the article. It should be obvious to anyone that you need to compose systems of different

What are the views on ISO 26262 functional safety compliance in the US self driving companies? This report is very light on details and only mentions ISO 26262 in the passing. Here in Europe it seems to me that functional safety is high on

I'm surprised he is surprised. Everybody knew Solaris was dead. I'm more surprised Oracle still had so many engineers working on it. I guess they where waiting out some SLAs. Of course Oracle is a horrible company and all but Sola
