Thanks for this post. It makes clear this 'pad abort test' is really a test of the amazing SuperDracos which could constitute their own launch system! SuperDracos are partially 3D metal printed and can fire months after being fueled.

I feel like this is a side effect of so many people writing random blog posts and other things in an attempt to help others, but in the large it makes it less clear because there's such a long tail of documents that are useful (for some things), that people like, but that cannot answer underlying questions or point to where underlying questions can be answered.

I've found the best solution is to try to find someone with whom you can have a discussion about what you don't understand and where you can find learning resources. Also, being able to find and read specifications can be very helpful.

> Crew Dragon will accelerate from 0 to nearly 100 mph in one second. The entire test is less than two minutes long, with Dragon traveling over one mile in the first 20 seconds alone.

That sounds totally insane, and yet at 4.5 g's was what the Apollo crews experienced on a successful launch.
>> The benefit of our device over traditional web wallets is security. Our devices are embedded. Everything that we wrote lives on the firmware. You don’t have to trust any app.

Errrr.... 'embedded' does not mean secure. While you may not have the full software stack of, say, Android or iOS, that doesn't make it secure by default. There's a network interface, some sort of processor, a variety of input devices etc.

I would hope that before making claims like "malware/virus proof" they would get both the hardware and software audited, as credit-card terminals generally have to be.
I'm not sure that Singapore is any more at risk of an abusive government than other countries. Freedom of speech and assembly might let you protest against an abusive government, but if the government isn't interested in obeying laws, those freedoms can just be ignored. It's not as though governments always obey their own laws.
The ever-tolerant HTML browser will automatically fix it up. The irony is in that this XHTML syntax has bled back into some code styles in HTML, however inaccurate in that language, but since the introduction of JSX and React, the self-closing tag is required again (all tags must close, or self-close, to be able to parse the file at all)
I know SpaceX is looking to make space flight more like commercial flight. Given that commercial airliners don't have anything like this in their design, shouldn't the goal be to get space flight to the same failure rate as commercial flight? Thus eliminating the need for an abort system?
Wow that's odd. Also, PHP has a built in function for filtering filtering plain-text user input to create HTML? That's... not something I would have expected.
Not just partly: from that Wikipedia article:

"It was announced in May 2014 that the flight-qualified version of the SuperDraco engine is fully printed, and is the first fully printed rocket engine. In particular, the engine combustion chamber is printed of Inconel, an alloy of nickel and iron, using a process of direct metal laser sintering, and operates at a chamber pressure 6,900 kilopascals (1,000 psi) at a very high temperature. The engines are contained in a printed protective nacelle to prevent fault propagation in the event of an engine failure."
What is the "container" overhead you're talking about? If you mean the communication between the web view and the mobile APIs, then you'd have that regardless, wouldn't you?
But were those through steel helmets? I really doubt that! I'd first believe there's a little hyperbole here. Also, cutting pikes is quite a different matter than cutting many other kinds of spear. Pikes were extraordinarily long, thus harder to move out of the way. Spear shafts can be cut, if they are anchored, but are much harder to cut if held in the hands. Pikes were sometimes used butted against the ground and the foot of the pikeman.

Skallagrim did a recent video which shows that a held (not anchored) spear shaft is pretty hard to cut in one blow. However, it's quite possible to destroy a spear if 3 or more cuts are placed in close proximity, even when the spear is held in the hands. I would guess that's what the author is talking about.

I'm a resident of southern California, and I have realized that the CHP is a better group to encounter than the local police or sheriff.

In my encounters they've always been right, always been fair, and have never escalated a situation. They're genuine professionals.

Our police, in my experience, are the opposite.

He wasn't talking about closing void elements, he meant self-closing void tags, like <img/>, <br/>, and <hr/>. These were introduced by XHTML to fit with the idea that every tag needs to be closed. HTML5 does away with the requirement, but the HTML5 grammar does explicitly support self-closing tags (http://www.w3.org/TR/html5/syntax.html#self-closing-start-ta...). At this point, self-closing tags are more of a visual preference, as they have a negligable effect on parsing.

The key with Ayasdi's work is that they manage to layer the TDA with different ML filters, which does stunningly well for the datasets they like talking about.

I also second the notion to read papers from the Carlsson lab, particularly one of the more application-oriented papers such as this one: http://www.nature.com/srep/2013/130207/srep01236/pdf/srep012...
Personally, I think they'd be better off doing an 'Apple'. They could use an open-source OS as a foundation instead of spending lots of resources going-alone with something idiosyncratic that's not used by anyone else. The resources freed up could be concentrated on improving the GUI environment (as Apple did) which is what 99.9% of your clients will be interfacing with.

But MSFT will never do this, they have the NIH mentality so deeply ingrained that they would rather die than look outside the MSFT World.
It is commercially licensed, but MarkLogic scales horizontally and is capable of full text search and structured queries (via xquery)

https://developer.marklogic.com/learn/2009-07-search-api-wal...

They also have Alert queries, which are similar to ElasticSearch percolation feature.

MarkLogic is also an ACID compliant store with configurable HA, as well as asynch replication to a remote site. it could potentially serve if correctly configured, as the primary store.

---

ArangoDB might have these capabilities as well. And again, it is an ACID compliant database so the data committed, the indices, and the resulting searches should respect transactional boundaries at any moment of time.
I had not looked at ArangoDB deep enough to understand what limitations it might have though. It does not have similarity search capability, and hierarchical data like ElasticSearch has
https://docs.arangodb.com/2.3/IndexHandling/Fulltext.html
----

I checked RethinkDB, and it appears that it suggests to integrate with ElasticSearch, meaning that elastic search will have a copy of the data from Rethink (and therefore subject to commit protocol of ElasticSearch)

---
Somebody already mentioned Riak with search capability.
I think this one is much more similar to Marklogic's capability (and it is free)
The advantage of these types of systems is that your primary store and text indexes are sitting on top of the single copy of data (or replicated invisibly within the infrastructure)

I haven't gone through all of the SoH materials, but FPComplete articles tend to be pretty good. Some articles are better than others, none left me feeling like I wasted my time, and some are excellent. I'm really glad to see FPComplete spinning up. I hope they come out with a conference or two (like Cognitect with Clojure/conj).

Real World Haskell is solid and was pretty comprehensive for system programming at the time (2008) but it desperately needs an update. Some of the libraries (e.g. persistent) have moved pretty far from it, web programming in Haskell has come a long way over the past few years, and applicative functors weren't even on the map yet.

Real World Haskell is a good resource but it shouldn't be your only resource. Then again, part of the fun and challenge of learning Haskell is that there's so much depth to the language that no single resource suffices.

Stephen Diehl's "What I Wish I Knew When Learning Haskell" ( http://dev.stephendiehl.com/hask/ ) is comprehensive and modern, but not really a beginner resource.
I wish there was an afl-fuzz like tool for fuzzing network traffic. By afl-fuzz for network traffic I mean a general purpose network fuzzer; not protocol specific fuzzer like the codenomicon ipsec fuzzer. Does anyone know of anything close? Remotely close?

There seems to be a significant overlap in what you would want from a network protocol fuzzer and a tool to reverse engineer a network protocol. Netzob is the only protocol RE tool that I know of and it seems that development has stalled.

I'm not calling you a fascist. Elst may have genuine points about the aggressiveness of Abrahamic religions, this doesn't make it OK to make this point over the bodies of Muslims today who had nothing to do with Somnath, etc. But that's what people use him for.

Just because someone lives within the boundaries of India doesn't give you the right to dictate anything to them outside the bounds of the Indian Constitution, something Malhotra (tell me, does he have _any_ formal training in historiography?) would do well to remember.

So maybe there was an Aryan migration or the IVC merged with them somehow. Do you really think that everyone who might hold the Aryan invasion hypothesis automatically thinks Indians are bovine Hindu Dravidian stock who never stand up for themselves? Try telling that to the Jaipuris or the Marathas for starters (very Dravidian, those two). This is all the worst kind of caricaturing you are engaged in.

Honest question: once the Macbook reaches the (approximate) weight and convenience of the iPad -- and has touch input -- is there any future for the iPad?

Sure, iPads are more convenient for giving to kids, but a Macbook with a surface-style keyboard and touchscreen kind of moots that entire line.

I see tablets and the requisite limited tablet software/interface as a necessary evil we had to pass through before we could make full-fledged computers small enough to have the same convenience.
That's all fine and dandy in theory, but from personal experience, I've found that it hasn't made much of a difference, probably for the same reason that the proliferation of automobiles has yet to result in the world's youth being proficient in automotive repair, or that the proliferation of the written word has yet to result in the world's youth being composed of poets and novelists.

The reason (in my observation, at least) is that being familiar with using something doesn't immediately translate to being familiar with creating something. Now, for a job where the using is important, a "digital native" might actually stand a chance (assuming that the something being used is similar enough to what he/she has used previously that patterns can be matched and the candidate's brain can perceive the thing being used as "intuitive" or "user-friendly"), but the article seems to imply the creation side of things (by referencing "media giants" and startups), where the skills don't completely cross over.
People Don't Want to Work or Think More Than They Have To

A great list, but the first point reminded me of my favourite support story. The application was a medical analysis tool, and there was a pre-analysis algorithm that could be run over a study to assist a human then scoring it.

A user called up with an issue that could only be one of two things - she'd gotten an error box when she'd tried to run the automatic analysis. There are only two errors at that point, and the text in the box tells me which fix to apply. Unfortunately she'd decided that the error box was due to a corrupt file.

"Please read out the message in the error box" => "The file is corrupted"

"Can you please read out the exact text in the error box?" => "It says 'the file is corrupted'"

"I haven't seen that message before, can you please read it out word by word?" => "The. File. Is. Corrupted."

"Okay, I haven't seen that error before, can you please read it out character by character, so I can go to the developers with the exact wording" => "T-h-e a-u-t-o-m-a...." (the start of the sentence "the automatic analysis settings have not been enabled", the solution for which is ticking a box)

This user had called asking for assistance and still refused to read the literal words in front of her until I got down to the character-by-character readback...
Many spellings can be traced back to specific print shops. "would could should", for example.
>One even said "If you don't want to work 100+ hour weeks, don't think about responding". This is a horrific thought.

Rest assured they are shooting themselves in the foot.
Once they are that reliable, I'm sure SpaceX could consider removing the abort system to save on weight. Though I assume that the SuperDracos are designed to also be used in space / on Mars.
It may only break those using advanced features, like A-B variations, but not for regular tracking.
Yes, you can use any JS library you normally would from ClojureScript. Pretty much the only JS "framework" that feels natural to use from ClojureScript is React, but things like jQuery, Highcharts, etc... all work just like they would in CoffeeScript.

I have a couple of fields I keep in my SQL tables... (migrateBatch,migrateStart,migrateEnd) ... migrateBatch is a UUID field that's set with the migrateStart, from there a regular process pushes to a queue, where the data is then fetched from the DB and updated in ES/Mongo/whatever... My sproc checks for updated records against the migrate/export date, and if I ever want to re-submit something, I just clear those fields in the table.

It's not the absolute fastest way to go, but it's very solid... I can usually have 500k records migrated in well under half an hour, the actual lookups for denormalized data are a bit heavy.
How about ==== and ===== and ======?

For security reason, I suggest PHP to implement such operators... :D Example:

"abc" === 'abc'; # ==> true

"abc" ==== 'abc'; # ==> false, single-quote vs double-quote

"abc" ===== 'abc'; # ==> true, this is how it works

j.k :D
There is the HTML5 Offline APIs for that. If you have an offline-capable web app, I think it should be possible for a tool like ManifoldJS to find out all of the assets it requires and package them into the app. Whether it actually does this, I don't know.

Why do you think it will have touch input? Apple seems fairly determined that laptops and tablets are different form-factors that work better with different ways of interaction.

I think there is definitely merit to this - Windows 8 showed how easy it is to get the hybrid approach wrong, and the gestures with the MacBook's multi-touch trackpads seem to me to be a better way than having to reach up to touch the screen all the time...

The opposite is true as well -- as the iPad increases in specs it will be able to do more of what the macbook does, for a particular subset of users who don't want any complexity behind their computing (less technical folks, for instance).
The point of a return from fsync is that you are guaranteed the file has been written to disk[1]. If you don't block on fsync, you can't guarantee the file was written to disk, because the server may have died in any number of ways.

[1] This guarantee occasionally fails too; If you have a battery-backed NVRAM RAID controller, the guarantee is that the write has hit the NVRAM controller with the expectation that it will hit a disk before the battery dies. Throw in a 72 hour power outage, a controller failure, or a massive disk failure, and you can't even guarantee that.
Yes, just like you should totally believe that your teachers are short-changing you by not summarizing perfectly the details they decided to not cover. And believing that you could remember all the details should they have done so.

Don't you feel horrible for never having been taught that contested unorganized, unincorporated United States territories like Bajo Nuevo Bank exist?

Your life must be upside down by first learning that the correct name for 'Brontosaurus' is 'Apatosaurus' and then to learn recently that it's now considered a valid genus of sauropod distinct from Apatosaurus.

You meant your example as a demonstration of how it's possible to teach string theory at the same time as F=MA. Otherwise, why did you even spend three minutes at the task? My response was to show that it isn't easy. If a teacher trips up over even a single point - eg, to explain that an atom is made of electrons, protons, and nucleus - then a future version of you will complain and say you were shortchanged, because there are atoms which are NOT made of those subatomic particles.

But few primary or secondary school teachers will know about these special cases, and for the vast majority of people it's useless information.
