On an ASR33 Teletype, backspace simply moved the carriage one character position to the left.

Rubout was a different concept entirely. The ASR33 had a paper tape punch and reader. The Rubout character was 0x7F, i.e., it had all bits set. So, to "rub out" an erroneous character from the paper tape, you could back the tape up in the punch to the desired character (by pressing a button on the punch; there was no character that invoked this function) and hit Rubout; this would punch the tape at all seven holes, changing whatever character had been there to a Rubout. (The software ignored Rubout characters on input.)

When the world moved on from Teletypes, it was natural for people to want a single keystroke that meant "delete the previous input character". But there was evidently some divergence of opinion in the industry as to whether that should be Backspace or Rubout -- notwithstanding that the ASR33's concept of Rubout didn't really map at all onto the new hardware.
My barber gave me one to play with as I sat down for my haircut the other day. I was eager to try it out, but once I did, I didn't really see the appeal, apart from a cute name. This thing is going to go the way of the hula hoop.
Totally agree with you. I'm not at all trying to say accuracy and bias can be orthogonal.

I'm trying to say some people think they have a good enough reason to throw away accuracy if that means they can change a societal bias. But that can only be a good thing if you agree with the change being made.
I used the instructions and 3D model from here: https://www.thingiverse.com/thing:1802260

and built a couple. My first 3D printer project experience. It was fun for me and the kids. Note that schools have started to ask kids not bring them to school as they don't really help with fidgeting and are mostly used as toys.
Bingo. Also, there is a nontrivial chance of going to med school but not getting into a residency program. And, residency is typically 4 years, not 3. In the case of my partner, she did undergrad (4) + post-bacc (2) + med school (4) + residency (4) + optional fellowship (3). So call it 12-17 years of training. Then, and only then, do you make a "starting doctor salary". But now you have hundreds of thousands in debt, interest payments, malpractice insurance, and, in some specialties, still insane hours.

If you're a doctor who is "doing it for the money", you have simply not understood the concept of opportunity cost. :)
Analysing AWS billing information is a bit of a 'dark art' in my experience. I wish they could improve some of their reporting tools to make it easier to reconcile assets.

For example, we switched to purchasing reserved instances up front to try and reduce our monthly bills (albeit at a higher up front cost). But trying to match up Reserved instances with EC2 or Elastic Beanstalk instances that are actually running is a real headache.

Several times, we've been caught with useless reserved instances sitting there not being utilised - because we had shut down a project or similar. Had we been able to see "Oh, we have 10 t1.micro reserved instances, but only 7 are being utilised by active EC2 instances at the moment" then we could easily know that we could provision another 3 t1.micro instances at no extra cost to experiment with something or for a client project. Or we could convert those t1.micro instances to another region or instance type to meet demand elsewhere.

It would also be handy on their billing reports if they delineated or showed the breakdown of the total usage hours against 'on demand' and 'reserved' instances. I know they _sort of_ do that now, but I think it could be better laid out so we can see at a glance whether we are getting best use from our reserved instances.
My team of consultants will write Android apps, and the customer takes ownership of the code base when we're done.

My wife would leave me if she knew how much I love Kotlin, but I could never use it for work projects because we just could not justify expecting random inheriting developers to know Kotlin and accept its legitimacy. That constraint lifted in an instant. It's a political thing, but it really matters.

This is a great article about fidget spinners:

https://geeksdistrict.com/inside-the-fidget-spinner-gold-rus...

"Over the last month or so, the spinning toys have gone from an elementary-school fad to a nationwide obsession. Unlike many other toy crazes, fidget spinners offer a wild-wild west for global capitalists looking to cash in on the craze. For one, there are no patents or trademarks to worry about infringing, so any factory can spew them out by the thousands. They're cheap to make and buy, so there's little risk in investing in, say, 500 or 1,000 of them. And unlike hoverboards, the craze that Chinese factories were cranking out last year, they aren't going to explode or catch fire.

"God forbid, SQLite"? It's honestly a great product and a wonderful stepping-stone. I wish more new projects used it rather than half-measures like Mongo.

Broadly, there are two mistakes I see people make:

1. Not taking enough chances in the first place

2. Taking a chance, but riding a loser all the way down or swearing off startups altogether after a single bad experience which leads to 1 above

You are a most likely an at-will employee. Your employer can dump you without any warning at any time. Any sense of loyalty beyond enjoying your work or your paycheck is misplaced.

Also, you could argue legitimately that I just eventually got lucky and I represent a raging example of confirmation bias now, but it's happened 3 times now, so maybe I've learned a thing or two by getting burned a lot? Or maybe not. Truth is a pathless land and all that.

One sentence advice: go work for Google, Amazon, Facebook, Apple or their ilk if you want a relatively safe high six-figure income and you can't stomach risk.
Some Smalltalks have them and they are used by Seaside but made optional in Seaside 3.0 because of the platforms that don't have them.

Academic institutions didn't spring up out of charity but due to general idea of the rulers of the day that it will make their and their subjects lives better. This including both financial and non-financial gains, both affecting economy in general though not linked to it in detail.

This is why most big academic centers are government funded and not privately funded - and it's always a high risk game and few businesses like high risk. (Even startups, most go for low hanging fruit and quick returns. Academia in total is supposed to go for long game with high payout instead.)

Patents came out of the left field, to protect and enhance private research, provide more incentive to do so, cover the huge costs which few private companies could otherwise bear without exclusivity. (Because private company has to make profit while government funding does not necessarily directly because it has huge buffers of cash and social capital.)

I have no idea. I just know all of the basic bitch Republicans have it set as their homepage. It's like, "Finally! All my basic bitch Republican stuff in one place! And a gay British guy singing the lead! Only a matter of time now before those stupid libtards see the light..."

So yeah, it's probably slightly racist.
In command contexts "." refers to the current line (e.g., :.,$s/a/b/ will perform the a -> b substitution from the current line to the last line of the file). That comes from ex which likely copied that from ed. I've seen "." used similarly in other contexts. 8-bit Microsoft BASIC used "." for the current line -- "LIST ." would list the last line that had been listed or edited. A number of assemblers use "." for the current assembly address.

The point being that there is a bit of a tradition of using "." for "the current thing" so there's a sort of sense in using it for the most recent command.

If you're really curious get in touch with Bill Joy.
Love it to death! And I've driven both the current Challenger (didn't like) and the Mustang (more practical, but not as fun). I actively chose the Camaro over a Cayman because of the price difference and over a Corvette because of the blind spot indicators and better storage space.
Hah—ironically, it's expensive enough it should be advising you to go with a cheaper option.
In the Soviet Union they used to show chess on TV and people would watch it like people football here in US for example.

I wrote the original integration, which required updating some Racket libraries to support HTTP pipelining, chunked transfer encoding, and streaming JSON serialization :)

My version was near real time, with a 30-60 second batching delay IIRC, and could still be what powers it for all I know.
All three companies are sitting on so much cash right now that if the ISPs do destroy net neutrality and start to poop on their customers, any of those three could sweep in and murder the ISPs right in the face.

I'm not saying it will happen, but if the ISPs present a large enough target of themselves, there's a lot of investment dollars waiting on the sidelines to pick their pockets.

I just searched for a vector if the shape, then cut it on a laser cutter.

Marketed by who though? Like the article says, there is no main company or companies behind this. Just lots of random products cheap from China being resold.
Yeah but doesn't that have more to do with the way the predictions are used?

It seems to me to be a stupid thing to do. This person seems more likely to get convicted again, lock 'em up longer. Instead of asking why is this person more likely to get convicted again? Can we prevent this in a redemptive non punitive way?

It's really useful to have that prediction/data but how you use it is more important
I think this is silly gobbledygook. The author seems to argue that you pull out of stocks when expected volatility rises. Well expected volatility can be a trailing indicator. The market has low volatility because investors expect great times, yet it suddenly crashes and loses 20%, and volatility skyrockets because investors basically believe that patterns continue forever and expect the market to continue to fall.

So now you sell, at 20% below peak prices. Maybe prices continue to fall, maybe not, but it's unlikely expected volatility will fall until the market starts climbing again significantly, say 20%. So then you buy back in, well above the lows.

Essentially this seems like a sell low, buy high mechanism, sell on dips, and buy on spikes.

Value investing means you invest in only what you can reasonably estimate a value for. You buy when the price is substantially less than it's value. You sell when value and price are similar.

Selling a stock you though was worth $10 and bought at $7, because it goes to $6 doesn't make sense if you believe in your original valuation. Buying it back because it goes to $9 doesn't make sense either.

If you cannot confidently assess value, you shouldn't be doing anything but buying and holding index funds.
ehhhhh sort of

it is very hard to replicate the behavior of someone that just loves being around people. i can usually tell who is a "natural" and who isn't (i.e. those that went through therapy, coaching and the like)

learning how to be around people can't really be done in a safe space since the world at large in unsafe. people will say dumb shit at you. people will cut you off. people will do unexpectedly nice (or mean) things. everyone is different.

the only way to truly learn these skills is to get out there and be vulnerable. i can see how classes and sessions can get you to a point at which one is comfortable enough to even BEGIN doing this (I went to a few social anxiety meetups with friends), but that alone isn't enough.

getting to the root of that anxiety with a psychologist is more effective, in my (limited) opinion, but that can be expensive for many

you CAN get pretty far on the basics though. most people like being around someone that is humorous and makes them feel good about themselves. you can go REALLY far by finding what someone really likes to talk about and letting them talk (while asking questions throughout)

podcasts with interviews from journalists or news companies helped me with this a lot
Such a refreshing story after countless of security researchers get threatened or sued when they report security vulnerabilities to the company that should have thanked them instead.
It isn't so much bad or negative as it is risky. A homemaker, male or female, becomes financially reliant on his/her partner. A partner who can die, become too disabled/ill to work, or who can leave after the homemaker has missed his/her key career/skill building years.

Women are more likely to be pushed or encouraged to take this important supportive role to benefit others while putting themselves at risk.
Are you non-sarcastically implying that an oil change presents as a major expenditure in owning and using an ICE vehicle?

If so, I get it.. you don't own a car; which begs the question of why are we discussing this?
That's fascinating. I'm curious as to why women have less debt even without as much financial assistance from parents. I'm thinking I could be because:

* Women go to cheaper universities
* Women get more scholarship money / financial aid from universities
* They pay more of it off while still in university?
* Universities charge them less in tuition (I doubt this is true)
* The fields in which women go are less expensive (Do universities charge different amounts for different undergrad degrees?)

Outside of that was there sampling bias? Perhaps the women population was a lot less than men sampled? Does anyone have anymore information into this?

My comment said nothing about "applied science" vs. "basic science." I'm actually talking about basic science.

You can do basic science but have very bad ideas based on very poor data which you interpreted poorly. You shouldn't be funded. There are enough people with good ideas for basic science who should rather get the money.

You can take recourse against non-specific action. For example the recourse to speeding at is using anti speeding laws and enforcement to create a disincentive. Labor laws, unions, and progressive taxes are the forms of class-action generally taken for recourse against this non-specific harm.
The most important thing that distinguished the Lisp Machine keyboard was that it had dedicated parenthesis keys. According to my sources, that was so you could hold a Hefty bag of nitrous oxide in one hand, and type s-expressions with the other. (Gumby can you verify this? ;) )
Indeed. The difference between "Security by obscurity" versus login/passwords is really scale.

Usually, some numbnut "programmer" sets a no-login and a simple password as a secret service account. It invariably is found, and badness ensues.

Whereas login/password is a 1/password_space chance of getting it. It's the combination of a default hidden account and no way to know/change it.
I'm not talking about their public cloud offering but rather their entire operational experience as one of the first companies to truly use next-gen architecture to build their software and data centers.

They're just now offering the same tech to the public with GCP products like Compute Engine, Spanner, BigQuery, etc. which shows in the level of sophistication and performance compared to Azure and AWS.
As a recreational player that plays in tournaments from time to time and is active in my local chess community, this post really only exposes that you don't know what you're talking about. For context, I'm not amazing but I'm no slouch (~95th percentile in the US) and memorization accounts for so little of my defeats or victories that it's practically meaningless. In fact, studying the openings is usually considered to be the least value-adding way to improve unless you're a titled player (usually 2400+ US ELO)
Well look, for the time being, it's a democracy. It could be called off due to lack of interest however. The FACT of low voter participation while politicians are bashing us in the face is at least as big a problem as being bashed in the face.

While on the "how HN works" topic, I have a question:

I'm working on an HN app reader idea that I think is unique (more to come) that requires regularly getting the front page posts and comments. I wrote a script to do that through the Firebase API but holy shit it ended up needing thousands of requests to get all the data for the current state of the front page.

So instead, I wrote a scraper script to produce the same thing, just with 30 requests (1 per front page post). (Trying to turn these damn <tr>'s into a recursive comment tree was a quite the mindfuck btw)

...is it ok to scrape HN? I see nothing in the robots.txt to say it shouldn't be allowed, and I actually feel better making 30 scraping requests rather than XXXX API requests.

EDIT: Also happy to receive suggestions. I'm coding in Ruby and don't see an obvious way to access the Firebase DB directly (quite frankly I don't even know if what I just said makes sense) so any help is appreciated.

Equity split – Looking for seasoned advice
So I've been building out my startup for 2 years now and have decided to pivot into a new idea that is a lot more promising and has signs of traction. My current situation is as follows, I own 51% my co-founder owns 49%, however, I can buy back all of his 49% shares for a nominal price if he doesn't hit a few milestones by the end of the year. It doesn't look like he's going to hit them.

The tricky part is, we're bringing in a CTO/technical co-founder for 25% and because of my other co-founder and I's agreement, he's suggesting that we form a new corporation for the new idea, and structure it 37.5%, 37.5%, 25%.

So he'll be getting his full 37.5% ownership in this case, where as in the other case he would be out if he didn't hit the milestones, which seemed to be heading in that direction.. Do I stick with the original agreement, or form this new company so we can get the CTO in?

Can we get the CTO in the original corporation, even with the original agreement in place?

Please advise!
Because it pays less (therefore enforcing financial gender inequality for which there is no good reason) and has been stereotyped for longer. It is sort of backwards thinking.

The often unspoken assumption is that stereotypes are strictly bad and evil. Without stereotypes, all the social conduct just breaks down and explodes - people suddenly become unpredictable.

However, stereotypes (including SJW stereotype) can cause big frictions between groups. Even more so when they're actually inaccurate, invalid or misapplied.

Another thing is something called "stereotype threat" which reinforces certain behaviors while punishing other - a kind of self fulfilling prophecy at times. You think you would behave as if some label would be applied to you therefore you behave to fit in. The drive to fit in is human, social and often subconscious.
I was thinking the same. There is a missing variable that makes this article incomplete.
