I suppose this was inevitable after the Arab Spring and the incoherent failure that "democracy promotion" has been across the Muslim world, along with the rise of right-wing-authoritarian governments.

Twitter is a revolution-causing technology. We were all bigging this up in 2011 when protestors in Tahrir Square overthrew the military government of Egypt demanding a less repressive one.

Unfortunately fewer people paid attention to the followup: the subsequent (apparently free and fair) elections were won by the Islamist party, who immediately tried to impose an Islamist constitution that was in many ways even more repressive. That led to a coup again, effectively going back to a military dictatorship. How it's going now: https://www.hrw.org/world-report/2020/country-chapters/egypt

Merely having free speech and free elections is not enough to ensure that people don't elect a repressive government. The liberal values need to be more widely embedded in the society, and more work needs to be done to counter propaganda and the inevitable racism and religious bigotry and supremacism that leads to unfree governments.

It has also been very convenient for the West to not pay attention to Turkey during the Syria crisis, while they engage in what look like proxy actions on our behalf against Syrian and Russian (and unfortunately Kurdish) forces. And host something like three million refugees.
They're already searchable. He's claiming to extract usable information from them in a way that can be instantly used by doctors, so that they don't have to read the studies or find an up-to-date summary of the literature by a skilled professional.

He even called what his software did a meta-analysis. My understanding is limited, but a meta-analysis is difficult and laborious to do correctly. You have to design the standards you use to include and exclude studies and examine each study to decide whether including it will improve or harm the quality of your results. For example, maybe a method to evaluate outcomes that used to be common has been discredited. Maybe a study was done under a principal researcher who has been caught fabricating results in other studies. Maybe a study claims to be double-blind, but when you read it carefully, it turns out that it isn't. Maybe a study is well-designed in every way, but it was designed for a slightly different purpose, so the data can't be used the way you want to.

Factors like these result in the exclusion of a lot of studies from a meta-analysis, after painstaking examination by researchers who have the expertise to design and run the studies they're reading. It's scientifically difficult and important work. The author is bragging about not doing this work:

> On July 2, 2018, GlacierMD powered the world's largest depression meta-analysis, using data from 846 trials, beating Cipriani's previous record of 522.
If you want to see the matrix point of view done well, there's Linear Algebra Done Wrong: https://www.math.brown.edu/streil/papers/LADW/LADW.html. You can read a bit about the motivation for doing it that way on that website.

The title is a reference to a somewhat well-known book, Linear Algebra Done Right, which avoids using determinants to develop the theory (resulting in a somewhat novel/cleaner presentation). It's unfortunately not freely available online (published by Springer – I would suspect most university students can get it freely through their library's website, however).

This is an interesting observation. The cool part about CLIP is that we can ask it any prompt we want. So “fixing” this loophole is just a matter of prompt engineering.

We already added a penalty to the score for text by subtracting similarity to “handwritten text”.

Any ideas what these solid color blocks would rank highly for that and actual drawing wouldn’t? I can update the prompts and regenerate the leaderboards this morning.
The phenomenon described by the quoted comment is called "temporal masking". There is "pre-masking", where a sound is rendered in-perceivable by a sound that _follows_ it (your "forgetting" case). And there is post-masking, where a sound is in-perceivable because of a masking sound that preceded it. And yes, this is due to inherent slowness / lack of temporal resolution in the auditory system.

Temporal masking widely exploited in all kinds of lossy audio compression (MP3, AAC etc), to remove the data that cannot be perceived anyway.

If I remember correctly, a lot of violence and multiple revolutions happened with the help of Twitter and YouTube all over the world. As long as violence is not in the US, it does not count, I suppose. That was probably what GP meant by saying "double standards".
The shipping companies guard their operations somewhat zealously. A lot of present company could learn a ton by being present as an engineer, but they keep even dedicated warehouse employees in a frustratingly low-information position.

This has been a bit of a problem in the West of backing "rebels" indiscriminately without checking if their politics is actually worse than the politics of those they're rebelling against.
The machine you built is very professional looking! Great job! I wish more people did high quality "last mile" integration" on their machines. Energy chain and powder coat makes a huge difference in perceived quality.

Couple of questions:

1. Why did you chose to mount the Y axis servos in that orientation instead of where the axis of the servo is perpendicular to the floor?

2. Since you welded the frame, how did you manage the mount the linear rails square? Shims? Post weld machining the frame via bridge gantry?

3. What was the total cost of this vs buying an OTS machine? I'm guessing around $12k.

Good riddance.
I have no opinion either way. It really is such a non problem imo.

I can definitely see the reasoning for using 1-based since you really are using cardinals (or ordinal or whatever). This is made maybe most clear looking at Haskell or other FP langs that usually have fst & snd functions.

At the same time, I could also see an array as sort of a map between ints and a obj in the array. This would allow for any number to be used there and why not just start with 0 then, since that is the "default" / first defined value of an int.

Actually haven't read Dijkstra's take on it. Will go do that.

While Halmos' book is lovely, I still prefer the geometric definition of determinant to the algebraic one: The determinant of a matrix is the signed volume (or area) of the parallellepiped spanned by its columns. Equivalently, the determinant of a linear map is the volume of the image of a unit cube by that map (or any arbitrary shape of volume one, not necessarily a cube). All the algebraic properties of the determinant follow easily from the geometric definition (multi-linearity, anti-symmetry, etc).

Really, I don't see what you like about Halmos definition of the determinant... I have just read it (page 99 of my copy) and he admits that it is a "somewhat roundabout procedure", just after giving the definition! There's other references that seem much cleaner (e.g. Spivak's calculus on manifolds, using exterior algebra).
Nope, different goals. I do a lot of security and reverse engineering, but here I want to design optimal data structures for searches in compile-time known static data.

All what is learned in Data Structure courses can easily put into a tool. Just like gperf, but not so limited.

Markets are a means not an ends. Putting 'markets' first is a way of hiding your morally objectionable ends behind a "someone paid me to do it so it must be good" argument.
It's simple, really. A 1U cubesat is defined as a 10 cm by 10 cm by 10 cm device, i.e. 1 litre in volume.

A volume of 2 litres therefore implies a 2U unit, in other words 20x10x10 cm (the actual dimension of the 20 cm part can be chosen arbitrarily).

you know when india literally banned internet to 8 million humans, for months ALL connections were simply shut, isps turned off their setup.
later when they did let whitelisted websites, i found out not all VPNs worked, it was a "cat and mouse" game but i managed to ssh into a vps i set up through some weird gimmick and ssh tunnelling was the only way to access internet and that too, via 2G internet. it was terrible to say the least and the one phrase constantly being used, big brother style was "misuse" which translated into "dont you dare criticize the govt".

i am saying stuff like this will continue to happen. even the assault against parler has shown such censorship can come in many forms and like it or not, it will happen everywhere

It doesn't matter if he told them or not to grab the zipties and make the pipe bombs, he was riling them up about how their country was being stolen from their dear leader, the only politician who cares for them, right before their eyes, and to take that sentiment to the ceremony of ratification of the elections he lost.

Parler was a place where people discussed these things leading up to an abortive coup or revolution, however you want to call it. The US clearly doesn't have the means to control these things as of now, Big Tech taking the matter on its own hands is merely symptomatic of the lack of legislation preventing the spread of radical fascist ideology.

While I have not seen either of those books before, I have another book by the author of the first one, Stephen Blundell. It's Quantum Field Theory for the Gifted Amateur, and I think you might like it. Not as a standalone quantum book, but perhaps as a supplement to a more "serious" treatment.

What a great way to find new books. Also those visuals are a work of art. In terms of features it would be nice to have a key and maybe a way to jump to a genre or theme.
I'm guessing that several of these attempts do not properly account for the negative externalities that are peculiar to the health industry.

Apple is taking a much much different approach in how they hope to gain a foothold in the health industry, starting with HealthKit and slowly chipping away at the problem with the Apple Watch getting FDA and related certifications.

Tim Cook is on record saying that if Apple is to be remembered for something with a lasting impact, it would be in health [0].

Unlike their peers, Apple's strategy in health is anchored on a very very long-term horizon. Would be interesting to see how their strategy unfolds. Fingers crossed.

Consumers with their first bulk-buying experiences have always amused me. When Sams Club (Walmart) started doing business around here everyone complained about "having" to buy big lots to get the good deals, and that storage at home was becoming an issue.

Yes, yes, welcome to the supply chain.
The cool thing about this model is that it actually doesn’t need to be trained! The way to tweak it is just to frame your question in the right way.

We’re doing to update the prompts probably to penalize it for similarity to “a solid block of color” or something like that.

I'd expect DNA's half life would depend on the environmental conditions. The conditions on the surface of the earth and at the bottom of the ocean are vastly different.

DNA stabilizing:

Much lower T (below 0C)
Practically no radiation (an ocean above you blocking it all)

DNA de-stabilizing:
Corrosive chemicals spewing from a nearby volcano (but only if one is near you!)
Radiation from said volcano and rocks (but they'd have to be closer still, due to shielding from the water)

So unless the 500 year half life is the "self-damaging" rate, I'd expect DNA at the bottom to last much longer.
I still use it!
I have two separate "Google apps" for two domains, and I just add new domains as aliases. It allows you to separately select DKIM keys for even aliased domains.

My previous post had an argument about how you can't avoid Facebook, as someone who uses Facebook probably already shared your contact information from their phone with them without you knowing anything about it.
> What ended up happening was that I spoke for about 15 minutes and then asked for questions and discussion topics. Nobody had anything to say, so that was that!

I noticed that happening with me in England when I first went there. It's not something I was familiar with in America, where it is normal for people to ask questions no matter what.

Why are English audiences so reserved, I wondered for a long time, without understanding what was going on. Actually, I was wondering what was wrong with me. Was I pissing them off? How? Did I appear clueless? Smug? Wrong? Was I talking over their heads? What was it?

Eventually an English colleague told me that English (technical) people default to not asking questions until they are absolutely sure they understand what the speaker is saying. They do that to avoid the possibility of sounding like they are going off half cocked.

Facebook and Google decided to have representatives.I fear that Twitter might decide to have it's own representative. It would be a nightmare here if these companies start censoring everything that the government asks for.
Erdoğan is starting loose support. AKP (his party) lost all 3 of the major cities in local elections.

I think the best scenario for Turkey would be Facebook and Google deciding to pull out their representatives from Turkey.

Legally the next step of Turkey would be to block %90 percent of the traffic. Which would be equal to blocking these sites.

There is a lot of AKP/Erdoğan supporters that use these services. This would weaken Erdoğan further.

Most educated people in Turkey do/can use a VPN anyways.
Only Erdoğan supporters, which are known to have less/none education (big surprise) would be effected from this.

I take this "both sides" argument as a sign that actually it's just bad - platforming the most extreme people from both sides in order to get the best fight, as if this was Jerry Springer without the chair throwing, rather than a sincere attempt to get at the truth of the matter.

Edit: it's definitely going to get worse. https://www.independent.co.uk/news/uk/politics/bbc-richard-s...

There is no way that anyone with that level of donation to any political party can ever pretend that they or their organisation is "impartial". Being a Brexiteer just makes it even more ludicrous and guarantees that all the ongoing problems and losses of Brexit will be hidden by the state broadcaster.

I wonder if this is another marketing gimmick similar to end to end encryption controversy they got into. I hope by ultrasonic they just mean beyond hearing and not really that watermark lives exclusively in ultrasonic frequency range.

Do they also talk about the process for identifying the participant who leaked the content based on the leaked recording? Do they need to retain the original copy of the recording to be able to extract the watermark?

I was raised in a similar way, and I have mixed feelings because I essentially ended up taking the path of least resistance. There was no pressure to do anything in particular, so I cruised through school doing as little work as necessary. I took exams in maths, physics and chemistry (because I found those subjects easy) and got very good grades but ended up going to design/art school because I thought it would be "fun" to be a graphic designer.

Then I slowly discovered how awful the graphic design industry is, and made a transition into tech. I taught myself to code at a youngish age so I have no idea why I never considered it as a career.

With hindsight I wish I'd had some pressure from my parents and gone to a "proper" university, studied something like computer science and really applied myself. I visited Cambridge after graduating and was blown away, I didn't even know what an actual university looked like.

In some ways doing what I wanted meant taking the path of least resistance (it's easy to pick the fun route), but ultimately led to disappointment career wise.

So what you're saying is: he called for violence against someone that disagrees with him politically. And the problem is, you apparently fall into the very category of: seeking truth isn't important, believing what you want is. Because you literally just fabricated a story to support Trump that's easily disproven by the very link you're commenting about.

Had you actually watched the videos: no, every single one of those people did not attempt to rush the stage, that happened exactly once. And in that occurrence he didn't even call for violence until the NEXT DAY, when a normal Presidential candidate would've had time to gather themselves and act like an adult... No, every single one was not arrested by secret service.

He spent MONTHS telling his supporters that the election was "stolen from them" and that they need to "fight like real patriots", but again, because you support him that's not a call for violence. Nevermind the end result: the violence he called for - you just don't agree that's what he wanted. Which of course is why he refused to condemn it while it was happening, and took a full day to say anything meaningful after every one of his political allies condemned him.

Hey everyone! We made this as a hackathon project over the weekend to experiment with OpenAI’s new CLIP model. https://openai.com/blog/clip/

Glad you’re enjoying playing with it and discovering failure modes! Yesterday we tweaked the prompts to penalize people writing text when we discovered CLIP can read. Looks like we should add something to prevent it from falling in love with solid blocks of color. Any ideas for how to describe that? (Someone below suggested a bonus for “complexity” but I’m concerned that’d make it fall in love with scribbles.)
