Let's represent the number 42,643,192, or 10100010101010111011111000₂, in different "floating point" representations.

Scientific notation with 5 significant figures:

4.2643 × 10⁷

Scientific notation in base 2 with 17 significant binary figures:

1.0100010101010111₂ × 2²⁵

Let's pack this in a fixed-length datatype. Note that 011001₂ is the binary encoding of 25.

1 0100010101010111 011001
1 mantissa exp.

This doesn't suffice because

a. We're wasting a bit on the leading 1.

b. We want to support negative values.

c. We want to support negative exponents.

d. It would be nice if values of the same sign sorted by their representation.

The leading 1 can be dropped and replaced with a sign bit (0 for "+", 1 for "-"). The exponent can have 100000₂ subtracted from it, so 011001₂ represents 25-32, or -7, and 111001₂ represents 25. Sorting can be handled by putting the exponent before the mantissa.

Thus we get to a traditional floating point representation.

0 111001 0100010101010111
± exp. mantissa

Real floating point has a little more on top (infinities, standardised field sizes, etc.) but is fundamentally the same.
You missed the point of the article. The husband screwed up with the cleaning too, even though he did the cleaning. It was never about the cleaning, per se, but the mental drain of running a household.

Read the article again. This is the key part...

"I was gifted a necklace for Mother's Day while my husband stole away to deep clean the bathrooms, leaving me to care for our children as the rest of the house fell into total disarray."

If the idea behind Mother's Day is to give mothers a day off, can you see why the gift of getting cleaners in would've worked, but the gift of offering to do the cleaning did not?

Seems pretty clear to me, but I suppose they don't mention that telling the judge could be bad for you.
> the executive path is actually the one that most of the scumbags take

Hmm.

Personally, I have tried to take all three paths. I find it creates the largest amount of potential.

Employee Hat: Develop stuff for the day job.

Founder Hat: Bootstrap by night and learn what it's like to be an owner.

Executive Hat: Work up the ladder by wearing the employee hat and bring what you learn as an owner/bootstrapper back to the day job.

Right, at a start-up the value of product, sales, and marketing is huge compared to that of engineering. Most engineers can create an MVP that will deliver the promises of the other 3.

The problem is trying to scale that product once marketing and sales do their job. I think the value of each of these 4 changes depending on the company size and tend to normalize to 1 as the company scales to the size of Google, Amazon, FB, etc.
What bullshit. Gender equality is basically becoming code for "man really should act more like women". Well fuck that.
Nice, well done!

I like the idea. That said, I would suggest trying a different business concept:
Offer the app for free, and let users select from a huge list of TVs. Once they found a suitable TV for their place, redirect them to amazon (where they can buy the selected TV) through an affiliate link.

This way a lot of people can try your app and you potentially earn much more.
Anecdotally, I feel like there are interrogations where the police kept asking questions even after the subject refused to answer or exercised their right to silence. E.g., you have the right not to answer questions, not the right to silence those asking questions.

Overly literal interpretation is overly literal.
This is exactly right. I've been in all three roles and all three are essential to success.

I can also relate to the notion that the engineers do all the work, which was a sentiment I shared early in my career before I understood the kinds of problems executives and founders had to solve. I cringe when I hear an executive say "How hard can it be? Get some bright bulbs in here and have code up a solution that doesn't have these problems." or when an engineer says "The CEO just parties with 'investors' and blows sunshine up our ass while we actually build the thing he is gets credit for." or when a founder says "I wrote the foundation this company at a dam hackathon in 24 hours and you're going to take 6 months to have an alpha release?"

I have seen again and again that people who haven't been in the role they are criticizing have constructed an understanding of it that doesn't capture what the actual role entails. Or in the the crowd funding case completely under estimating to cost or effort to do some aspect of development they have never done before.

If the company is hitting its milestones, people know what they should be doing, and the problems that pop up all seem that they can be overcome. Then you know all three classes of people are doing their jobs well.

When things take forever to get done, nobody knows why or how the thing they are working on fits in, and every week there is a new problem that changes all the priorities and efforts, then you know you're on the way to being dead as a company.
Which is why it's sexist. The implication is that if her husband were a better feminist he would be perfectly able to anticipate and provide everything she wanted in a friction-free and effortless way.

The fact that he doesn't proves he's still mired in patriarchy, which of course he needs to be educated out of.

Assuming your partner is sort of okay, I guess, but essentially ideologically defective is not a particularly healthy basis for a relationship.

Aside from chores, it's not as it men - feminist or not - never provide emotional support to women. I would be astonished if the husband never listened to problems, provided cuddles and backrubs, and all the other emotional maintenance that men give their partners.

I sometimes think this culture has a very poor record of educating people how adult relationships are supposed to work. Unfortunately this article seems to be an example of that.
Anyone here ever used SRV records for local development? I really like the idea of running a local DNS server with port information built in instead of a full-blown service discovery/routing/service mesh setup.
> Since floating point units were so slow, why did the C language end up with float and double types ? After all, the machine used to invent the language (PDP-11) did not have a floating point unit! The manufacturer (DEC) had promised to Dennis Ritchie and Ken Thompson the next model would have one. Being astronomy enthusiasts they decided to add those two types to their language.

Wait, what was the alternative? No floats? How the heck would people calculate things with only integers?

edit: AFAIK bignums are even slower, and fixed-point accumulates error like crazy
It's so bad for me... I read the whole article and I cannot figure out what 'emotional labor' is.

The scenes described play out constantly in my home. There are these major gaffs in both directions: For me, I cannot infer how to set the table from what's on the stove, and my wife is therefore convinced that I have a learning disability.

For her, she is incapable of using the Maps app on her smart phone to help me when our destination changes after departing the house. And I am therefore convinced she has a learning disability.

Let's accept that things are structurally different upstairs and therefore inputs are not processed the same way and therefore the actual problem is not in the wiring, but in our expectations.

A Raspberry Pi is "regular computer" enough for me, at least as a hack platform. Ditto all the other ARM SBCs which are largely similar. (Odroid is fairly nice, too.)

The special microcoded systems are dead, but ARM is a nice enough design and it's available from a ton of different sources.

> This reminds me, one interesting thing I've noticed over the years is that early PC's RTCs were pretty accurate, but the most recent ones, as in the past few years, are horrible

Insofar as sensitivity to thermal conditions is an issue, early PCs tended to be big, airy, ventilated boxes and have less bits that would ramp up to high temperature under load but drop down in other operating regimes. So that may be a factor.
Seems to me it's a false equivalency seeing how one choice puts you "in the city", and the other has you living way the hell out by the airport.

> On average, our automated systems catch more than 3.2 million suspicious accounts globally per week — more than double the amount we detected this time last year.

Holy crap that is a lot of suspicious accounts!

It's impossible to find political conversation on twitter without multiple accounts named like `HouseWifeXX937` (always something with weird characters then numbers at the end) in the middle of the conversations and rarely reply like you would expect a real person to do. Sometimes I wonder if I'm in a conversation entirely with bots and it gets depressing; why would I even want to bother using Twitter beyond talking with people I know are people?

Nowadays I mostly ignore any strangers.

The vast majority of quartz references in consumer devices could be a lot better, but they are not fine-tuned at the factory. They're just "close enough". So they drift a lot.

A simple tuning procedure could make almost all quartz clocks you own a heck of a lot better. But in many cases this is hard to do because the manufacturer never put the tuning components (a variable capacitor or the like) on the PCB.
7-11 years ago everyone was saying exactly the same thing about the cost of living here as they are now.
You can thank Louis Rossmann, in part, for this one.

His livelihood does depend on it (although he has acknowledged that, as electronics get more disposable, he will inevitably end up having to shift into something like software or hardware design), but he has made a really admirable effort of actually going boots-on-the-ground and lobbying at political hearings.
This is a great effort that will open the doors to many people who haven't even thought they were able to attend this type of school. If only more universities did things like this, you'd start to hopefully see more equality of access to opportunities rather than the traditional "good high school grades->good undergraduate degree" wheel that many don't necessarily fall into for one reason or another.
That's kind of a double-edged sword.

If I were to tell you that an unarmed black man was shot by police, and that most people in one political party thought this was bad and most people in the other political party condemned people who protested the shooting, do you think you could guess which political party is which?

Heck, look at Joe Arpaio, who recently got pardoned for unconstitutionally targeting Hispanic people who haven't been convicted of any crime. Which party was generally in favor of this, and which party was strongly against? Again, the same parties as the first case.

The conservative movement in America — even a lot of people in the "small government" basket of the movement — has a huge blind spot when it comes to the police.
I've hired people from Ohio. The salaries are higher than 45k unless you are straight out of college.
Naturally these figures are related to specific accounts, too. I wonder if they can aggregate spending based on origin location and how much higher the amount would be.

For example if you're doing something fishy with moving money around you wouldn't move, say, $100k from a single place. No, you'd move $5k 20 times from likely multiple places. It's trivial to setup new accounts to then use for ad buying.
> If you do want to talk to me, I can tell the juvenile court judge or adult court judge and Probation Officer what you tell me.

It's missing the explicit warning that "what you say can and will be used against you in the court of law." I think they should add a clause to the end stating "and they can use this information against you to get you in trouble."

I hope they try more innovative stuff in their new stores. Such as making self-checkout the primary means instead of the alternative. The long lines are often a problem and a single row of the checkout machines has 4-6 machines vs 1 or 2 people run counters. So it would speed things up

They could even extend it to offer more services like ordering delivery and install services.

It also makes a lot of sense in their current system.
>In that photo they are wearing distinctively downmarket clothes: middle class overcoats and the like

Middle class? Compared to what? Royal cloaks and tunics? They look like normally fine overcoats, the kind that can cost anything from $200 to several thousand dollars depending on the marker.

The distinctively British obsession with class and royalty never ceases to amaze me (especially since it's rarely actual upper class people that take joy in bringing others down as "middle class" -- not to mention that in Britain middle class is leveled at people making much more money than most commenting sneeringly at the "middle class" make, as if those sneering identify with royalty themselves).

That would be the ad absurdium argument :-). But the EEZ[1] argument is the one that is in play here. Generally the 'oceans' are international water, and what is under them is not claimed by any country.

There are economic and strategic assets here, whether it is oil or methane clathrates, fisheries, or places to establish forward operating bases, these things are 'easy' to claim in your 'own' territory and 'hard' to claim in international waters. Step 1, redefine them to not be international waters. See the South China Sea and now Zealandia ...

This is why the "We're a nation of laws"[0] statements (from many individuals) referring to DACA recipients and illegal immigrants concerns me, there is no way that law enforcement has the resources to simultaneously prosecute all infractions, nor would we want to, but its very easy to be for an overly zealous justice system when it impacts people you are not fond of but doesn't impact you. I would say we're all guilty of that in some ways, but it shows a total disregard for humanity I think to think that just because a law exists that it needs to be enforced blindly regardless of whether the enforcement of said law actually benefits society and whether the lack of enforcement would negatively affect society. There are plenty of laws that we don't enforce and shouldn't that are/were used to disenfranchise certain minorities [1], and just throwing your hands up and saying "we're a nation of laws" is dishonest at best.

This really just reads like a smear campaign. I'm not making the claim that there's not something wrong, just that this article does an incredibly poor job of showing evidence that there's a real problem, or even what that problem is.

They claim that he's "come under fire from scientists and statisticians who’ve spotted all sorts of red flags ... in 50 of his studies", and provide three links to back it up. Two of those three links just focus on the same 4 articles, and the third claims 45 papers contain "minor to very serious issues"[1]. The majority of those issues are minor, and out of those the vast majority of those are "data duplication" and "self plagiarism". I can see that being an issue as far as professional conduct goes, but it wouldn't reverse/invalidate the results of the study.

Left over from that, there are 15 papers with "critical data" issues, three of which have had corrections issued. And from the titles of these papers, they don't sound like groundbreaking science that's likely to lead to policy changes anywhere. And my guess would be he knew they were useless and didn't put much time into them.

So, maybe the guy really is a piece of #(&, but this article did a pretty poor job of making a convincing argument to show it. The focus on minor issues, and issues that have no regard on the outcome of the paper, and papers that have pretty useless outcomes make this smell more like a smear campaign than an attempt to protect the public from evil scientists.

You're 100% right... in the United States.

In other countries, this isn't even a consideration or thought, because health care cannot be denied, and is independent of your job.

I grew up in the US (through college), and returned in graduate school. Paying for health care as a grad student + independent consultant was horrifyingly expensive, and I'm lucky that I was able to do it.

In Israel, where I've lived since 1995 (except for grad school), there are lots of reasons not to be a freelancer -- but health care isn't one of them, I'm happy to say.

The original LISP machine, the IBM 704, had CAR and CDR as primitives. And boy, were they primitive:
