[@makuogoku2102]

@@TD-yx8yo be it DNA or be it RNA, they're all codes that program our bodies. If I remember right, when I was in highschool learning about basics of coding, the code that we wrote in C++ is somekind of raw code, we must let computers translate that code into another code before running it. It's similar to DNA being the raw code and mRNA being the translated code, it's rules of this world anyway, like how math exists in every form on earth. the earth codings is much more complicated than human's codings tho.

Crashing is a good thing, if there wasn't a crashing safeguard the data file will get corrupted and have an irreparable damage for both your computer and the server.

[@ColorfulMusicNeko]

Sousuke Aizen Well, damn!

[@Kris2340k]

would you rather it blow up xD

[@janekmuric]

Not really. Not handling exceptions can't cause data corruption unless it's a low level function (for example memory managment in C). And even if it bugs out at any low level the only data you lose is in RAM (or any *single* file your process has opened), which isn't that bad since most new programs (MS Office, some Chrome extensions) save multiple copies of the file (two in temporary dir, and one at real location) and auto-save every few minutes.
And don't get me even started on that "_both you computer *and the server*_" nonsense. Nothing would happen to the server.

[@TrabberShir]

+Tom Scott To be fair, the mess you keep referring to from comment 14 isn't a mess because it is hard to fix, but because every possible fix seems to break standards compliance and violate expected behavior in some way. The mess isn't the effort in fixing but the effort in deciding which fix is appropriate.
Luckily comment 36 clarified exactly how the standards say it should be handled and sadly it was determined in subsequent comments that making chrome standards compliant in that respect would untenable due to some assumptions in the design of "the extra validation we do on receiving URLs over IPC" so they were back to deciding which way of breaking URL handling is preferable to fix the crash.
Honestly the code wasn't too bad, there was a one day turn around between deciding on what to change and merging the change into beta.

[@PeterKasting]

Hey Tom, as the guy who fixed this bug in Chromium -- I'm not really sure why you spent so much time (or, really, any time at all) on null-terminated strings. It implies that the crash has something to do with misinterpreting an embedded null, which, as you said near the end of the video, isn't true. The crash has nothing to do with null-terminated strings.
Really the problem is simply that canonicalization wasn't idempotent when it was supposed to be. This could cause problems regardless of what value is ultimately encoded by the doubly-escaped string and there are a variety of places in which different bugs appeared as a result. It was too bad that right as you got to the point where I thought you'd explain one of these in more detail, the video ended :(

@Isaac Thompson What sort of potato are you using for a computer?

[@TheDutchMagicTeacher]

it doesn't work for me did they fix it that quickly?

[@TomScottGo]

Quite possibly! Google roll out updates to Chrome quickly and silently, so it'll depend when yours chose to auto update and which "branch" it's on.

[@toast_recon]

+Tom Scott I just selected it in the title text and started dragging it and it crashed. Try it out!

[@trejkaz]

+TheDutchMagicTeacher I found the same thing and then I found that on Windows, it did crash, whereas on OSX, it only crashed the one tab.

[@TheDutchMagicTeacher]

+Tom Scott if you select the tekst and try to drag it it does still crash on my end

[@kainpwnsu]

There's a difference between an unintended crash, unhabdled exception, and simply halting for safety.
Remember the days one Windows was so unreliable and sometimes displayed the "Blue Screen of Death"? That wasn't windows failing, but bad programming in an application you were using or in a hardware driver. Windows was doing you a massive favor and not allowing the malfunctioning application from potentially destroying the system, or at least preventing it from leaking into other application spaces.

[@znicoshi]

finally someone said it. take my like

[@danielthecake8617]

Or...
One time I was trying to boot a windows computer but it kept trying to delete its own files. Required me to completely the hard drive before reinstalling windows.

[@Abfalder.J]

It’s sort of playing with codes. As a small example, an alphabet can be made into a code by using numbers to represent them. 01 = a, 02 = b. And so on. Computers have a long list of these types of values.
If you look at your browser where they show the link to the website you should see a number of characters after % symbols. This is how computers send information over the internet.
%30 is equal to 0, and %30%30 is 00, see how they just get added on to itself, you could use %30%30%30 and that would give you 000.
What happens is %%30%30 becomes %00, which gives the computer a value called a null, which the computer doesn’t know how to handle it.
TLDR: the link gives the computer something it doesn’t understand, it gives up, crashes the tab.

I always enjoy these videos - one of the most interesting things about computers is, in my opinion, their limitations and what happens when an error occurs and it's not handled properly.

[@weecountygamer0956]

Dude this is so weird I thought this was a recent video and I tried out the link and was wondering why my Chrome wasn't crashing and I was like "Wow, they fixed that fast" not realising how old the video was

[@Hevii_]

Same dude lmao. Thanks, UA-cam algorithm.

[@SamuraiCake42]

I tried "a/a%00" in Bing (don't ask why), and trying to show the character, it stopped responding, opened up 10 of itself, and crashed my computer.

[@UrSoMeanBoss]

as a low-level C/asm programmer, It's nice to see someone explain part of the fundamentals to people who otherwise wouldn't know. Thanks for including the bit about strings :D

[@UrSoMeanBoss]

***** Well it's rare that a situation would come up that requires a full function or program to have to be written in ASM for best performance... Normally it's just using GCC inline assembly to augment the efficiency of a C function. Here's an example for a math function that rounds up to the next power of 2:
//--------------------------
#include
static inline uint32_t example(uint32_t const Value)
{
uint32_t ResultMask;
__asm__("bsrl %0, %1
\t"
: "=g"(ResultMask)
: "g" (Value)
: "1");
register uint32_t const TrueValue = 1

[@UrSoMeanBoss]

***** My only experience is with C, and inline ASM isn't in the standard. This is a GCC specific feature. Other language compilers may also have a similar feature, but to my understanding; the more high-level, the more unlikely.

[@Ryndae-l]

+UrSoMeanBoss It is in the standard, as a common extension (§J.5.10 on the draft I'm reading)

[@dennisvoliver]

+UrSoMeanBoss I'm making CPU emulators right now, it's nice how low-level concepts are still relevant to high-level architectures like this one :)

[@UrSoMeanBoss]

+Dennis Oliver my group loves to know people who do awesome. And that sounds pretty awesome. Are you doing that as a job or a hobby?
