I don't know if that's what OP is saying, but it seems fair to say that it's at least enough bullshit that it should probably never be used as evidentiary.

The states who pioneered its adoption (New York and Maryland) have both abandoned it for being costly and ineffective. The FBI has abandoned comparative bullet lead analysis for similar reasons[1]. The National Academy of Sciences found the tests to be "full of holes", and that not enough study was being done to ensure its reliability, which was a finding that the United States President's Council of Advisors on Science and Technology under Obama concurred with.

The general consensus now seems to be this[2]:

> An understanding of the metallurgical principles operative in the melting/casting process as well as the data acquired for this study, indicate that any forensic conclusions which associate unknown bullets with the “same source”, and/or “same box” should fail most or all Daubert criteria.

> Somewhat unintuitively, American corporations today enjoy many of the same rights as American citizens. Both, for instance, are entitled to the freedom of speech and the freedom of religion.

I keep hearing that but what does it even mean?

Corporations don't have religious beliefs, people do. Can the corporation be Muslim and have 100% Mormon employees?

The only controversial bit I could locate in a different source was the corporate political spending: https://en.wikipedia.org/wiki/Corporate_personhood - but there is a bajillion plus loopholes to do that without the need to resort to legal fiction.
I'm using JWT for auth on a microservice so that it doesn't have to phone home to authorize requests. For revocation, the user service pushes the revocation to the microservice, which maintains its own blacklist. JWT works great for us because it contains all of the identity necessary for auth decisions on the microservice. An opaque token would require the microservice to phone home to get a user's identity data.

There is some very serious issues with it, so many issues it can't be considered scientific, at least not yet.

>Further criticism came from the 2009 NAS report on the current state of various forensic fields in the United States. The report's section on firearm examination focused on the lack of defined requirements that are necessary in order to determine "matches" between known and unknown striations. The NAS stated that, "sufficient studies have not been done to understand the reliability and repeatability of the methods."[23]:154 Without defined procedures on what is and what isn't considered "sufficient agreement" the report states that forensic firearm examination contains fundamental problems that need to be addressed by the forensic community through a set of repeatable scientific studies that outline standard operating procedures that should be adopted by all firearm examiners.[23]:155 Another report issued in 2016 by the United States President's Council of Advisors on Science and Technology confirmed the NAS's findings, finding only one appropriately designed study that examined the rate of false positives and reliability amongst firearm examiners.[40]

A minor nitpick in the article, the $12.99 Amazon prime subscription does not cover their spotify competitor streaming service. I've always thought this was a bit odd given that it does include a netflix-esque amount of streamable video content. If I had to guess, I imagine it's all related back to the royalties situation in music. You do get "Prime Music", but it's not the Spotify competitor, that would be Amazon Music Unlimited. That service is an additional $7.99 if you're a Prime member.

eBooks are also mentioned there, but you don't get a huge library for being a Prime member either. Rather, it's a selection of ~1000 written things (books, comics, magazines) that is constantly rotating. Kindle Unlimited is another $9.99/month. You can do the Kindle library thing as a prime member, but that's one book a month drawing from a similar pool as Kindle Unlimited, which often doesn't have current best sellers anyways.

I guess props to Amazon for being so confusing in their myriad content subscription options that the author couldn't get it right. To get the same kind of all-you-can-consume options that spotify provides across the different media mentioned it's actually ~$30/month. Still strikes me as odd how "cheap" TV and movies seem to be in this model. I'm very curious about that now.

Indeed. At times it is scary what level of trickery and manipulation is used to drive addiction (or engagement as some like to call it) in social media. Especially when you consider that these methods are also indiscriminately used on young kids, as soon as they get their first smartphone and start installing apps like Snapchat (which can be pretty early nowadays).
The Wikipedia page doesn't seem to support the thesis. One can plausibly argue for quite the contrary, IMHO. In fact, many outstanding scholars in STEM of that era, including a few names in the cited Wikipedia page, were also religious scholars (jurisprudence, theology, hadith etc.). Arabs were so much lost before the advent of Islam that the neighboring Persians and Romans apparently had little to no interest in them. History is more complicated/nuanced of course, but these are important points.
Right, the 2-sphere is the surface of the 3-ball. I think "volume of a sphere" is okay though. It just means the volume enclosed.

>a cube in 3 dimensional space is always considered to be 3 dimensional.

So "cubes" are taken to include their interior. That makes sense I suppose. I wonder what the surface of a cube is called. A "box" maybe?
Good luck, I wish you all the best. Be aware of your negative thought patterns. Absolutist statements like your last sentence is not necessarily true and a real symptom of depression. Change your internal monologue and good things can follow. Change it to "at this moment these issues are holding me down".
The behavior the article is, to me, way more bizarre than the curse of dimensionality.

It's tempting to think of data sets as "point clouds". This article is a reality check for me: you can't safely apply intuition about 2- and 3-d point clouds to higher dimensional data. I suspect that this explains why methods like tSNE seem to produce unstable results depending on the parameters [0]. The notion of a "neighbor" in high dimensions is just not what I think it is.

I suppose the same is true for high-dimensional cost surfaces. Gradient descent is often described as "like walking down a hill". But without a deep understanding of high-dimensional geometry, I'm not at all confident that I know what a 4-, 10-, or 1000-dimensional hill looks like.

The lesson: Be skeptical of my own geometric intuition unless it is firmly backed by math.

>>Textbook treats history of india as only Mughals and British.

History goes as back it as it can go. Unless you wish to transform the entire school syllabus into a kind of a history specialization there is no way you can teach all of Indian history. At the same time, you have to teach history whose effects are relevant to you.

This is the biggest dilemma that Indians face throughout. You have to learn in which language? Most likely in almost everybody's case that is 'English'. So you have to talk about that bit of history in great details given the effects of colonization reflect on the masses and their culture even now.

North India relishes Hindi/Urdu/Hindustani poetry, movies, songs and all based on literary legacy of the Mughals. Heck even to a great extent food and clothing habits come from that era. So you have to talk about them.

Then you go as far as you can go and talk a little about people like Ashoka etc. But then again, it makes no sense to keep talking about era of bygones which doesn't influence the current state of affairs in any real way. Or like I said, you just have to toss out other subjects and just teach history.
Even if true, the lone fact that a person had abused a substance (or not abused but used - taking a substance without a prescription doesn't imply abusing, there actually are some people capable of conscious and constructive substance usage) means nothing and should never be used against the person in any way. Separating families for just this alone is ridiculous. You still are to prove that the person has developed actual addiction/habit, aggressive behavior and really harms anyone but him/herself in any way (more than the sanctions will harm them).
I don't see any reason why using maglev means the track has to be anything clever. There are methods where the vehicle contains the only active part, and the track can simply be a metal strip, such as servo-levitation (varying the strength of an electromagnet on board the vehicle with feedback), induced current levitation, or by using a rotating set of fixed magnets.

> sends the user to run the same script on the control server, which we chose to host with Linode

Just went through a 3 month long issue with Linode, slow download speeds at peak hours on Cox cable. They said to call Cox, Cox escalated me to a guy who did not understand mtr tool. On Linode's end, they would not acknowledge any issue & burned up many hours of time trying to convince me there was no issue.

Ended up switching to Digital Ocean since Linode refused to call Cox on my behalf after I failed to get through. We also had the slowness issue with Linode with users in Dallas, where our servers were located. I suspect this will only get worse as net neutrality is repealed. I'm not saying these ISPs are slowing things on purpose, but if they do so accidentally, then imagine if they have green light to do so on purpose.

Linode also uses Cogent, FYI.

Hello LineageOS-15.1 (Oreo)
It might just be too risky in their minds. I can't speak for every user, but if Spotify dropped the big labels I'd just go elsewhere. There's already enough platforms for discovering new or different artists, Spotify's value to me is being able to pick a song or band I like on a whim and know that they'll probably be there.

To me that was obvious, but you are right, it is better to be clear. I have added a below sentence my blog post.

"I would like to mention that the above results don't mean that zheap will be better in all cases than heap. For example, rollbacks will be costlier in zheap. Just to be clear, this storage format is proposed as another format alongside current heap, so that users can decide which storage they want to use for their use case."

I vaguely remember that there was some annoying guy on comp.lang.c++ years ago who relentlessly campaigned for "operator .", because he was sure that it would somehow make C++ amazingly powerful and easy to use. But many people seemed to disagree with him and had problems with it, because it never happened.

Anybody remember what the controversial benefits and problems of "operator ." were? Here's something I just found about that:

Not if you have higher status to begin with. Not if you are their friends to begin with. And if you merely have power over them, they will notice that their beliefs will attract the contempt of people who have power over them. Of course, this probably won't work on public web forums. Of course, this won't work on your boss. Of course, this will not work well on strangers.

Then again, the best way to do it is to act as if you were ridiculing a third party. If they get offended, try not to notice, and direct your condescension at those other people you're pretending they're talking about. Give them a way to save face.

Whatever the means, the idea is to stress that epistemic relativism is not socially acceptable. Make them feel that thinking such thoughts has consequences.

>If it weren't for the oddness of the language, Lua would be a perfect fit. Near-C speeds, super flexible, no recompiles.

True.

But there are also other dynamic languages that can go as fast as LuaJIT and of course faster than V8: Common Lisp and some Scheme implementations.

Both are very elegant languages, moreso than Lua (which is very peculiar.)

However, for the goals of an editor, my choice would be Free Pascal with Lazarus. It is already complete for cross-platform UI deployment. And compiled code is really fast.

It's not just aggression. Neglect is a primary reason children are removed from homes where drug abuse is happening.

But, yes, without actually proving that there was drug abuse, those children should not have been removed.
I used to use mingw to cross-build a project.

At one point, after updating the toolchain from gcc 4.x to 7.x and from mingw32 to mingw-w64, it started to produce broken binaries.

The manifestation of that brokenness was that binaries refused to start properly on systems where the toolchain was not installed. It just silently exited during startup - no crash, or error message, or anything.

This applied both to binaries that were cross-built on linux, and binaries built using MSYS2 on Windows.

I decided to just switch to clang-cl + MSVC headers instead, which worked properly. The only gotcha there was the need to store the headers on a case insensitive file system (I chose vfat) when compiling on linux, because the case of the includes aren't consistent (e.g. Windows.h vs. windows.h), even in the MSVC headers themselves.
That's one advantage of having small kids. I definitely enjoy playing with some of the toys more than they do :)
I met both the CEO and their investor recently at a conference where they presented. Both are very happy with the growth and the revenues.

They are currently breaking even, as their models predicted. Even paying full price for each ticket. Their innovation was getting Mastercard to issue and process their own card, so the movie theaters can't block them without violating Mastercard policy!

Now their next plans are to promote indie films and much more. I do not think they need all this tracking to make that happen. Also, Uber tracks you before and after the trip.

At Qbix we would never resort to this kind of thing, however the current movie theater model sucks and the prices just keep rising. And also the founder is the same guy who founded Netflix and Redbox! This would be the third time he is upending the movie industry.
You mean like Berlin, where you get max. 36k€ a year for Full Stack Dev and pay 13k€ for Rent? I think the main reason for Cities in Europe become tech hubs is the extreme low cost for Devs and other tech people.
Having visited recently and met with several tech companies and western firms utilising it I'd say it is already a tech hub, and has a bright future. The sheer number of graduates being produced, and the proven ability to scale up operations there makes it really attractive.

It is also a lovely city to visit, which is always worth bearing in mind when it comes to where companies might open a satellite office...

Very happy to see Edinburgh get more recognition. I spent a year on exchange there while at University and was just blown away by the city. Great tech scene, incredible University (of Edinburgh), so much history and just wonderful people.

If I ever decide to leave Canada, that's probably where I'll go.
Expensive yes but a survey the other year had it as the best city in the UK for disposable incomes, an average of £800 per month. Probably in part due to the sizeable financial and legal sectors here. Given the fairly stiff competition for developers in the central belt of Scotland my (biased!) opinion is it is one of the best places to live in the UK, especially if you have, or are planning, a family.
Have non-religious social outlets ever existed in any great numbers though? I can't think of any widespread institutions that provided community other than sheer physical proximity, which itself would largely be a 1:1 relationship with church membership in most places.
That Hinduism is older than Islam is an absolute no-brainer. Islam dates to the 8th century, whereas the oldest layers of the Vedas are likely 3000 to 4000 years old. The question is the origins of the Vedic religion and its adherents. For Hindutva, it's of vital importance that Hinduism originate in India, but as I understand the scientific consensus it's quite clear that the Aryans came into India from the outside and subjugated an extant population (likely Dravidian-speaking).
