@_trish_xD This is fine. You should be able to pass variables into malloc and those variables might resolve to zero.

malloc(0) is legal C.
let that sink in for a second.
some compilers return NULL. some return a valid pointer you can't dereference but CAN free().
both behaviors are correct according to the C standard.
you can allocate zero bytes of memory, get a pointer to nothing, and then dutifully free that nothing.
and the language just shrugs and says "yeah that's fine."
this is why C developers have trust issues.
English
@ChesshirCasey @Mallchad @maxliani It is not what you said. They did it because it was faster, not because C also has no bounds checking. Different reason, same outcome. They were open to having different semantics than C, if it wasn't for speed. In fact, bounds checking [] is allowed in STL, but not common.
English
Actually, no.
You can totally dereference a std::vector out of bound, write outside of the memory boundary, corrupt memory. You can remove from a container in a way that corrupts iterators. You can easily enter a bad state from exceptions.
No, the std library doesn’t give safety
Dave W Plummer@davepl1968
If you use the STL, you can write safe code in C++ Everything is object, allocator, and algorithm-based, and that's it. You NEVER call malloc or free or use strxxx() functions. You never see, access, or operate on memory directly. It's different than regular C++, but less different than Rust.

@ChesshirCasey @Mallchad @maxliani Not true. I read an article a while ago that claimed that they chose not to bounds check [] solely so that STL would not be slower than C code in the default path, i.e. purely for marketing reasons. These days bounds checks eliminate easily, so this is pretty stupid.
English
@ChesshirCasey @Mallchad @maxliani You could have had the same choice with a safe default if [] was the bounds checked one and at() was not checked.
English
@ChesshirCasey @FUZxxl @maxliani This is not the reason at all.
vector::operator[] is infact an overridable function, it can take on as good safety measures as at() or better.
Better yet you could NOT provide operator[] in th efirst place.
The simple reason they decided performance > safety.

@stacycay @lolnochilly It starts at capitalism now. Capitalism was still a progressive force when much of the world still lived under feudal society. The French Revolution was a bourgeois revolution asserting their class interests over the king.
English
@lolnochilly Well yeah they’re adapting terms but it didn’t “start at anticapitalism” like op said. I think a rough framework that left tends to favor equality while the right favors elite rule would be a lot more useful
English
Actually “left” and “right” in politics was invented in the French Revolution of 1789. It was to describe which side of the National Assembly you sat on. The left wanted democracy, the right wanted monarchy.
Capitalism hadn’t been invented yet. Karl Marx wasn’t born either.
Johanna ☭ RCP/RCI@dialecticaldiva
For everyone that’s confused, the left of politics STARTS at anti-capitalism. Liberals are not leftists, the democrats are not leftists. Socialists and communists are leftists.
English
@ChesshirCasey @maxliani So what? Are you banned from innovating?
English
English
@ChesshirCasey @maxliani Why not make the default safe? Unchecked indexing would still be available through at().
English
English
@maxliani They don't and it's kind of a tragedy that at(), not [] was chosen to be the bounds-checking one. Never seen any style guide mandating at() over [] either.

@ndr3www3 @paramitanoia As if you have to use any of the bullshit parts. You can use C++ as ”C with classes” all day long, the committee won’t hunt you down.
English
within every C codebase above a particular size, you will find an ad-hoc OOP system retrofitted onto C; there will be 12 function pointers in a struct, all of which return structs which must painstakingly have their first 16 words made compatible with `struct obj_common *`

@Brandon_Fuego @KozicaJ @joni_askola They said “within reach”. These places can also be repaired faster than it would take them to burn through their reserves.
English
@KozicaJ @joni_askola How exactly is Russia self-sufficient?
Are you presuming if completely shut off they could function?
English
People overcomplicate how to defeat Russia.
The solution is incredibly simple:
We just need to fund enough cruise missiles for Ukraine to systematically destroy every Russian oil refinery within reach.
Cut off the fuel, and you end the war

Unironically, I don't know anyone who achieved anything meaningful with OpenClaw
Pirat_Nation 🔴@Pirat_Nation
NVIDIA’s CEO says OpenClaw did in 3 weeks what Linux took 30 years to achieve "OpenClaw is probably the single most important software release ever. If you look at its adoption, Linux took some 30 years to reach this level. OpenClaw, in what is it, 3 weeks, has now surpassed Linux. It is now the single most downloaded open-source software in history, and it took just 3 weeks."
English
@Uqimerioni @cmuratori It’s because of this graph that went viral recently. To call that “adoption” is of course absurd.
English
@cmuratori Yea, or maybe also npm downloads, these are just my guesses for his explanation of "adoption", I don’t know how exactly he measures that. Anyway it’s a very strange statement.
English
What is the context for this quote? Linux installs number in the estimated billions. Is Jensen claiming that OpenClaw is somehow now installed on billions of machines? And if he is, where is he getting that statistic?

It’s the fourth anniversary of the Russian full-scale invasion of Ukraine. Our list of verified deaths has reached a grim milestone: 200,000 names. Read about it, as well as a new map of Russian losses we are introducing, here:

@chenhegaocx @InterestingSTEM this is the same thing as that
English
@InterestingSTEM holy fuck thats disturbing. Hunt you own animals and eat them. These pigs are being fed slop all their lives then merked like this and you eat this shit. Get a hunting licence go hunt wild animals kill them in a natural way and feed yourself how nature intended

This is how electrical stunning is performed in slaughterhouses. A controlled electric current is applied for a few seconds to cause immediate loss of consciousness before slaughter. The goal is that the animal does not perceive pain during the process.

@ukroposting @BookerBiro He did that to prove to the international community that it was an anti Soviet alliance.
English
@BookerBiro He applied to join the Axis powers. Why do you think Stalin hid from the Red Army after the invasion?
English
When encircled, a revolutionary state buys time, builds strength, prepares the blow. Joseph Stalin did not trust Adolf Hitler, he outmanoeuvred him. Strategy is not betrayal. It is survival.
Only children confuse tactics with capitulation.

Claude Code has regressed an absurd amount in the last few days.
Timestamps no longer update unless you un-focus/re-focus the tab. "thinking" doesn't show at all. I had a query run for 6 minutes with 0 output. This is genuinely unpleasant to use.
