For anyone who doesn't want to do the conversion, that's 17 days.

Mmm yes. 5 bit two's complement.

I shouldn't make fun of it we've definitly made some ISA that weird.

[–] [email protected] 2 points 1 week ago (1 children)

what's the general rule for translating negatives from binary? did you just do like 17 - 2 • (-1) or something?

[–] [email protected] 4 points 1 week ago (2 children)

I used what known as 2's compliment. Take the complement (flip all the bits - here that would give you 01110 which is 14) then add 1.

It also has a max of 31 days possible. Which has... implications.

Among many other duties I manage the safety and claims database for an outsourced industrial cleaning company and let me tell you, some of the plants my company works struggle to make it a week without an accident, meanwhile some will go years without an accident. We also have one plant which had its last accident during the Bush Administration. Its absolutely wild how much safety can vary from one industrial facility to another

[–] [email protected] 3 points 1 week ago (1 children)

🤔 .... What implications? ಠ⁠_⁠ಠ

They must sacrifice an undergrad on the 32nd day

This is actually how chromatography works. The mobile phase is 0.1% formic acid and 0.3% blood of the innocent.

[–] [email protected] 2 points 1 week ago

blood of the innocent

Well, We work with what we have.

Unless it's a signed integer, then it's -1 and they're expecting something...

[–] [email protected] 9 points 1 week ago (1 children)

A 5 bit long signed integer? What kind of weird system you using ? :p

[–] gens 8 points 1 week ago

Two's complement

[–] [email protected] 3 points 1 week ago

Only if you're using a sign bit rather than two's compliment (a sign bit allows for two representations of 0)

It's even worse considering that they only have five boards. They expect at least one accident every month

[–] [email protected] 22 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

I work in the LTL freight industry, if we go 30 days without an accident or an injury we get a free BBQ day with unlimited food for everyone. We're talking burgers, hotdogs, chilli, chowder, chips, drinks, etc. Sometimes they even do catering. Our last one they did Hawaiian Food for 2 days (they got too much) which definitely made everyone happy.

I've been there for almost 10 years, we average about 2 per year.

Edit to clarify: 2 BBQs per year. We're really good as getting hurt.

[–] [email protected] 7 points 2 weeks ago (1 children)

I wonder if that's still cheaper, because it makes people value safety of others but also because it raises the burden to report smaller accidents and workmans comp fraud because of peer pressure.

[–] [email protected] 3 points 1 week ago (1 children)

The cost is in the lost productivity from having someone off work with injuries. A barbecue every 6 months seems like a bargain.

[–] [email protected] 3 points 1 week ago

It really is, the average time loss injury in our company is usually upwards of 30k down the drain. And just an accident can be catastrophic in terms of cost as well.

A BBQ compared to that is nothing.

Less than Truck Load

Basically if a company want to ship pallets of crap but they don't have enough to justify using their own truck

Think TForce, YRC, Oak Harbor, FedEx Freight, etc.

[–] [email protected] 3 points 1 week ago (1 children)

Right. I'm not American though, so I don't recognise any of those companies except for FedEx.

It’s a great way to save on number boards

[–] [email protected] 32 points 2 weeks ago (1 children)

Not so much on board space

[–] [email protected] 24 points 2 weeks ago (1 children)

You can save if your lab is unsafe enough!

Perverse incentives

It bothers me it's not in 4 bit "bytes" even though I know it's just a convention for computers

[–] [email protected] 9 points 1 week ago (1 children)

The four bit sections of eight bit bytes are called nibbles, you know because nibbles are small bites

[–] [email protected] 2 points 1 week ago

Ugh jeez.. right. I literally always mess that up

[–] [email protected] 2 points 1 week ago (3 children)
[–] [email protected] 7 points 1 week ago (1 children)

That's a matter of convention, not technical definition. A byte can be any number of bits, depending on hardware. For a while 6 bit bytes were common. RFC 791 refers to an 8 bit byte as an octet

French-speaking people do too it seems. On second hand websites in Switzerland you always see that some disks are listed for e.g. 250 Go and others for 250 GB, depending on the first language of the seller.

4 bits is a nybble

You can do all of math in binary, it isn't just for computers. In fact, the proof for "Russian Peasant Multiplication" was written in binary.

I love the leak in the other room. Get ready to reset the counter folks!

[–] [email protected] 4 points 2 weeks ago

And the fumes being vented inside that room.

[–] [email protected] 23 points 2 weeks ago

It's telling that their counter only goes up to a month

The author of this comic has a number of excellent coffee table compilations: https://www.tomgauld.com/comic-books-v2 (unaffiliated -- I just like them :))

-1 days? (or 17, without the overflow)

[–] [email protected] 12 points 1 week ago* (last edited 1 week ago) (1 children)

Twos complement (invert the bits then add one), so its -15 days.

Otherwise 00000 and 10000 would paradoxically both equal 0 and make bitwise equality checks very difficult.

[–] [email protected] 2 points 1 week ago

Good point!

[–] [email protected] 14 points 2 weeks ago (1 children)

They've never gone more than a month without an accident? Find a new work place immediately!

[–] [email protected] 5 points 2 weeks ago

With a large enough workplace in the wrong industries it's really easy to have something that could count against it.

I work in the LTL freight industry, we get quite a few.
