Yes. In particular, teaching tau instead of pi makes many operations in trigonometry more intuitive.

It doesn't matter to mathematicians because they have spent many years learning to suppress their intuition. It does matter to engineers and technicians.

Whether you're talking about rich or poor, famous or not, educated or not - there are good and bad people.

Our instinct is to make assumptions like 'rich so asshole', and there may be correlations between some of those categories and rate of occurrence of good and bad, but the differences are small compared to the normal panoply of personality types.
I suppose the next level is to learn to enjoy the negative outcome, from an observational stoic perspective, every experience has a unique quality.
No, it is strange, because C decides to dereference according to the datatype of "a" in both cases, and not according to how the user syntactically declares what is to be understood as array and index.

In other words, if a is char[]/char* and index is int, C does

*((char*)a + (int)index) and *((int)index + (char*)a)

and not as one could expect

*((char*)a + (int)index) and *((int*)index + (char)a)

for a[index] and index[a] respectively.
How to detect CVE-2019-14287 using Falco
Chronicle blocked me for using an adblocker so this is from the SF Examiner [1]:

>Better Market Street will be implemented in three phases: Market from Fifth to Eighth streets is phase 1, Market from Fifth to Second streets is phase 2, and Market from Van Ness to Octavia Boulevard will comprise phase 3.

This leaves 9th-11th streets, and streets past Octavia open to traffic. Also, certain types of transport are still allowed. I believe taxis (excluding rideshare apps like Lyft/Uber) were mentioned in another comment, and the streetcars will be allowed as well. I’m sure there’ll be other exceptions.

> there's so many other rules that are uncontroversial (unless you find yourself in a position where you want to incite violence or advocate for child exploitation).

It's disingenuous to lump these together as equivalent to misgendering. Child exploitation and violence are against the law of pretty much all nations in the world, and there is a clear consensus. As well as harm caused.

That line hasn't been drawn yet for gender. For one it's not clear how many genders exist. Are they fluid day by day, can people change in and out of them at will. Do I misgender someone if I fail to keep up. Is this a biologically supported concept, should we really open the Pandoras box of forced speech, etc.. etc..
Thank you for mentioning that, because that actually reinforces the overall point more deeply - it speaks to the exact farcical nature of the act in question - the awarding of the highest, globally accepted award toward actions that are claimed to be geared toward the enacting of a peaceful world. This is obviously false, if you award a leader ostensibly on his initial actions, without any knowledge of what the next 3 years will hold. Awarding Obama a Nobel Peace Prize was a symbolic decision, meant to reinforce the notion that solving the racial issues in the USA would somehow have some kind of long-term effect on US politics, and indirectly, on global geopolitical activity (lol, that definitely worked out super well, looking back from 2020).

Has anyone told the current US leadership that we were terrorists to our own set of oppressors, back in the day?

Sorry, but this topic upsets me because no one seems to realize what all of these subtle actions really mean in the aggregate. Maybe I'm just a kook.

How does Noam Chomsky's work on linguistic contribute to computer science? And are there applications? He is always described in the popular media as a "linguist", although many works seem to be directly related to formal language in computer science to me, but I'm not sure.
Could you possibly open a ticket for this performance issue? If you attach OS version, hardware specs, system load, it may be possible to reproduce and get to the bottom of this. Another strategy would be for you to try HyperSwitch (https://bahoom.com/hyperswitch) and see if that one is also slow (you can change the activation delay to 200ms to match, and play with thumbnail quality and see if that impacts perf).

I worked a lot on the thumbnail generation which was making the app slow on my setup. I thought the perf is good enough, but it looks like not enough
Accountability and a requirement to change are quite orthogonal.

As someone who has worked in corporate companies, here is a list of reasons why Oracle, IBM, Microsoft, Google, VMWare, Deloitte etc. are "par for the course"

* If you are upper level management at Blue Chip company "Initech", the last thing you want to be dealing with is a smaller B2B provider, with a hipster name like "Data Badger". Being smaller means more risk (not necessarily but thats the culture). You want the big safe boring companies.

* Big corporates are still wined and dined by Oracle's sales teams etc. Yes you might have to do your mandatory HR training about bribes and corporate gifts, but this stuff still happens under the table. Its business, it might not be ethical, but its business.

* Cronyism etc. management tends to circulate around companies closely connected with each other. A Microsoft manager might float to Vodafone or JP Morgan. When they get there, they are more likely to throw any of their old MS colleagues a bone when it comes to service contracts etc.
This is why networking is so important in LinkedIn for corporate careerism.

* Did I mention sales already, yes, but these big companies have large sales and marketing budgets. Those buzzwords are expensive you know!

* Those sales and marketers target managers and people with a high influence / low technical understand co-efficient. Don't get me wrong there are smart managers out there that know their stuff however they are generally a rareity. So they tend to drink the kool-aid from the big tech corporates e.g. "Hey Bob, I think Microsoft's Foobar Cloud Hypervisor, can streamline our data acquisition and increase synergy in the business".

* When you take your first hit of Oracle's software or services, you are effectively tied into service contracts which make it painful to leave but easy to extend. You might spend £200million for a 5 year contract, then three years in you see a new technology offering for an extra £4million etc. That's relatively pennies to what you've already sunk into the service contract.

* Marketing and branding which you picked up on in your post. There is a reason you see IBM or Oracle advertised a lot in the Financial Times, Economist, New Scientist etc.

Hope this explains why Oracle et al. are dominent in the industry.
I live in Germany, where ATMs always require you to take out the card before giving you money. The reason I've heard for this is to avoid a particular scam that goes like this:

1. Eve spies on Alice as she enters her PIN into the ATM.

2. As Alice takes her money, Eve taps her on the shoulder and gives her a 10$ bill, explaining that it fell down to the floor when Alice didn't notice.

3. Mallory uses the distraction to swipe Alice's card from the ATM without her noticing. Now Mallory and Eve have both the card and the PIN and can empty the account.
Samantha Power, who served as a Special Assistant to the President and Senior Director for Multilateral Affairs and Human Rights at the time, revealed in recent podcast that even Obama's close staff thought the price was BS and inconvenient to the president. They saw the price just as a attaboy.

Survey: What does it take to be a good data scientist?
I consider myself a rather well-informed person, but this is the first time I've read about Harris Media involvement in the last German election and I'm German. All I can remember is indeed the "Russian interference" and how the AfD is supposedly financed out of Russia.

But that Bloomberg Businessweek article [0] unearths some scary details:

“We took that 300,000 (AfD likes), and Facebook created a model of them and used their lookalike audiences to find the closest 1 percent of German people to match that audience,”

That "1 percent" sounds extremely familiar, particularly in a far-right context [1]
It makes me wonder who originally came up with that concept, was it Harris Media or was it the idea of their client, the AfD?

IIRC the limit according to the standard is £100,000/day but most banks impose their own arbitrary limit. Assuming things haven't changed in 5 years, this[1] lists the limits for a lot of banks. I can also add to the list that Monzo's is £10,000/day.

There’s a lot more to it than that. Even when they’re young, there’s a lot more hours in the day than the hours they spend at school (and below school age there’s an even bigger difference). Engaged parents will help their children a lot more in those hours (or ensure they have childcare providers who do if they are working). Reading to children at home. Having books they can read themselves and encouraging them to do it. Getting them to do simple maths puzzles in everyday settings (how much change? How long until bedtime? That sort of thing). Later on, making sure they do their homework and helping them out with parts they didn’t understand from school. Talking to them about the wider world. Etc.

Those engaged parents will also be the first to complain if the teachers spend too much time with the children who don’t get that at home. So without engaged parents and a supportive home environment, children are at a significant disadvantage.

There's nothing stopping you from following the monoid laws in C. There is also nothing stopping you from breaking the monoid laws in Haskell.
Let's think of it this way.

If a police battering ram is stolen, you can't really use it to attack millions of houses in a day. There have been known cases of police personnel misusing their roles. Police have broken into houses without warrants. But the scope of damage is limited.

Whereas digital backdoors can be used to jeopardize millions of devices in a very short period of time.

Sure, you could require a warrant. But it doesn't reduce the risk of someone misusing digital backdoors.

All it requires is one breach.
Indeed I tried and even though I can get a switch without any frame of UI showing, it is very hard to press and release fast enough. It's not a delay like I implemented, but most likely the UI being terminated before the next frame, so nothing shows.

In any case, adding a preference to change/remove the delay will satisfy people who want the UI to show faster (https://github.com/lwouis/alt-tab-macos/issues/8)
It's like trying to teach someone without any sense of rhythm, pitch, and tempo to play music. Yes, they can learn to do the mechanics, but the result will not be enjoyable.
I see your point now. My mistake.

In order to avoid iterating over the file three times, he writes the second version, which does require understanding laziness (in order to avoid high memory usage).

I stand corrected.
> Now, if it said "fulfilled by Amazon" - or it went to a different section of the site ("Amazon Dwellings" - I dunno) that was clearly an Amazon branded product, manufacturing and fulfillment system for houses, that'd be a different thing.

Except you run the chance of getting a counterfeit product if it's fulfilled by Amazon - and even if it's sold by Amazon, because of the whole co-mingling thing. Can you imagine getting a counterfeit house?

Because of political bias. Just look at the introduction of the (fake) Nobel Prize for economics. It exists purely to legitimize a neoliberal economic ideology. Awarding Chomsky a Nobel Prize would undermine that goal.
Suppose a public PGP key is communicated in the URL.

I don't think there are enough PGP keys in the world that simply trying those keys in a certain prioritized order wouldn't find a lot of keys.

This way you could recognize who someone is talking to based solely on their 'malicious browsing' send hashes.

In general, anytime you know a secret in the URL comes from a low (min-) entropy distribution you can use the truncated SHA-hash as an oracle to (approximately) figure out the secret.
Obviously, if the secret is a 128 bit session cookie, you won't find that by brute forcing. Heck, in that case your 32 or 48 bits of hash prefix won't even be enough to uniquely identify the session cookie.

When you get to a 64 bit secret (say again a session cookie), with a 48 bit prefix, things already get dicey. It seems possible that some state actors can already brute force 64 bit secrets, and with a 48 bit prefix, you'd get about 2^16 ~ 64000 (more, but dont wanna compute exactly) candidate session cookies. Those can actually be tried at the website to see if they work.

There seems to be an unhealthy obsession with beating C in some corner of the Haskell community. It makes even less sense nowadays when some of the most popular languages out there are Javascript and Python, clearly C-grade performance is not required anymore by the vast majority of applications.

I actually wrote a comment (in 2013, but the page I'm referencing doesn't appear to have changed one bit) where I shared my experience looking at haskell.org's introduction that was filled with FUD regarding C and how Haskell was so much better and faster:

https://news.ycombinator.com/item?id=5090808

Maybe if they had actually tried to teach me the language instead of that bad faith "used car salesman" tactic I'd be writing Haskell these days.

Except for the occasional visit to the office to give a few high fives and have some chit-chat I work remotely.

Until recently we used Toggl to track work time and the guidance was to have "6h of focused work daily".

I'm managing 5h 15min-ish, but only when working remotely. When I'm in the office that number organically drops to around 3h 40min.

Only person really doing those hours(and above) is one guy who's not into chit-chat.
I have this problem too - only, it happens a LOT. I've had people use my Gmail address but without the "." to sign up (or try to) for Playstation accounts, Apple accounts, Paypal, Skype, Bank accounts, plus it's pretty common that I receive wills and other sensitive legal documents, property deals, you name it. The legal docs etc are likely due to other people mishearing/mistyping someone's email which I can understand, but I'm constantly baffled by how often people must type in their OWN email address incorrectly for important situations too.

Often I can just ignore the signup confirmation emails and it doesn't go any further, but it's surprising how often there is no confirmation link sent out and the account gets opened without verification of the email address. At that point, it can be incredibly difficult to get the problem rectified. Most companies don't seem to have any procedure in place to deal with this situation - Many online companies only have an easy way to contact them if you are one of their customers, so I often have to resort to resetting that user's password to get into their account and use the company's contact form to try and get things straightened out from there. Sometimes even that isn't possible, e.g. because 2FA prevents me from resetting the password, so about the best I can do is unsubscribe from their marketing emails and leave the account active.
Reading this piece reaffirmed a lot of what I had been feeling in the SFMoma my last couple of visits. The place just felt lifeless. All the art was really disconnected from the world, and the abstract stuff seemed especially pointless.

Will Your Uploaded Mind Still Be You?
I could work from home 80% of the time if I wanted, but actually prefer working at an office because I find it less distracting. The office is a 'clean' space where I'm only surrounded by work related thing. I have my work computer on my work desk with my work setup, and nothing else. There is pretty much nothing else to do here other than work. Home is cluttered and I'm surrounded by all kinds of 'distraction' not related to working.
Sometimes it is just cargo-culting.
I have the best relations with people that I can insult freely and they know not to take me too seriously.
Sometimes I feel like I'm the only person in the world who has any affection for SVR4 and its derivatives. Everyone seems to hate it, despite it resulting partially in Solaris, XENIX, the universally despised SCO and Unixware, NCR UNIX etc. It ultimately ended up being a huge influence on Linux, which started life as a Minix clone and eventually added more and more interfaces from SVR4 (eg. iBCS2, SysV IPC) as it grew. SVR4 even had a half-decent packaging system for its time as well.

I suppose everybody feels like too much other core "UNIX" stuff came from BSD - vi, TCP/IP etc. Plus the SVR4 vendors typically insisted that you pay separately for C/C++ compilers etc...

Ask HN: What's is the state of the art of lifelogging?
I want to log everything about my life.

A wearable camera paired with advanced computer vision would go a long way, but I haven't found a practical solution yet.

I already log the easy stuff:

- Computer/phone usage (RescueTime, ActivityWatch, keylogger, TimeSnapper)

- Location (Google Maps Timeline, GPS Logger)

- Pictures (Google Photos)

- Internet usage (Google History)

- Fitness (Mi Fit, Google Fit, Strong)

- Finance (Mint)

I even experimented with 24/7 background audio recording but didn't have much success with Google Cloud Speech-to-Text.

The biggest challenge for me is manual logging. Taking pictures of my environment can go a long way (food, receipt, barcode, injury, product, book, ad, ticket, activity, weighing scale) but it becomes more difficult when I need to retrieve and log information from memory (cash spending without a receipt, weightlifting workout, pain, mood, idea, question, todo). I don't like single-purpose apps designed to log a specific domain of events and would prefer something more general purpose. Free-form typing/speech with context-aware semantic tagging and auto-completion could be interesting ways to reconstruct a timeline of events from memory, but it seems like a challenging AI problem that probably isn't solved yet.

Where can I find more about the state-of-the-art in lifelogging, self tracking, quantified self, activity detection, narrative timeline reconstruction? What can I use today to help me collect more information about my life? Even a simple, fast and ergonomic time-stamped journal that syncs across devices seems difficult to find (I've been using my own implementation for the past 6 months but it's starting to show some limitations).
