Indeed. The bitterest thing is that cheap access to space would have flowed forth a river of money to tech companies in every voting district. They could have sold uncancellable payloads like it was going out of style, and instead they crucified themselves on a single doomed political game.

Pixl is definitely cool. I don't think it's a really fair comparison for one thing Pixl is more like Photoshop rather than Illustrator. Pixl is a Flash app which probably makes a difference to some people as well.

Both are really cool online tools though.
When you really start looking into it, what projects actually are good for Mongo?

EDIT: It's nice and quick for prototypes. Ironically, I'm building one with it now.
It's a really fascinating bug in that respect.
I'd put it more strongly. If your apps are anything more than dumb opaque storage, if they ever process the data they write, they have a schema. There are certain fields and values your code is relying on to work as intended. "Schemaless" merely means your schema is not written down anywhere, and you might not have any tests that could detect whether any version of your apps ever wrote data that violates it. I say "apps", plural, because in my experience if the data store has been there for more than about a year, anyone who thinks there's just one piece of code that uses it is in for a very unpleasant surprise.

On data migration, I don't think the if/then/else version is even feasible. If there have been n versions of your apps, there are 2^n possible states any particular record could be in depending on which versions of your apps did and did not update it. I've seen Notes documents after a few years of this that are in such weird states that not even the dev team could say just what the hell happened to that doc or what correct (well, least bad) behavior of the apps would be, much less what the current versions of the apps would probably do. You can kind of get partway there with apps that have existed and been actively maintained for as long as any of your data has been there, but trying to write anything like new analytics over old non-migrated data is hopeless.
I wonder if it was gen_aggregator.py again, 6 years later.
The problem with relational databases is not the schema or the relations, it is SQL.
Onewheel: The Self-Balancing Electric Skateboard
"Computers are really fast at sequential scans, less so at random-access stuff."

This is true if you're simple talking about raw IO throughput, but in terms of algorithmic searching the truth is almost exactly the opposite. For example, to find a record in a 100 million record table with a unique key using sequential search would require on average a scan of 50 million records. To access the same record when that key is indexed requires accessing/testing a maximum 23 or 24 entries in the index (2^23 is roughly 10M) and then direct access of the exact record needed in the table. Indexes are used because they speed things up exponentially, even though it may be true that random access IO is much slower than sequential IO.

People, I suspect, also have much higher throughput when scanning sequentially compared to random access of items. But imagine trying to find the single person in a copy of the Manhattan white pages (is there still such a thing?) with the name 'Horace Greeley'. Would you prefer to scan sequentially from the beginning (no use of an index) or make use of the fact that white page phone books are indexed by lastname, firstname?

Of course, because sequential scanning is so much faster than random access it will always be faster on tiny tables. It will depend on the system and record size, but I'm guessing indexing will take over as faster method as table size grows beyond 5k records or so, give or take an order of magnitude. Not sure of exact numbers but you get the idea. As number of records goes up from there the speed advantage of indexing over scanning grows at exponential rate.

Interpreting the Data: Ten Ways to Teach Math and More Using Infographics
This observation isn't really a complaint about Yale or college in particular.

Yale is not her parents, not her church, not the Connecticut Health Service, not the National Health Service. What does Yale owe her any more than all the rest of us owe her?
Make no mistake, this policy directly results in Yale students not seeking out help for fear of the consequences.

I should know; I was one of them.
Well, that's one way to encourage people to turn off an idiotic filter. Hopefully more game updates / media will add random "expertsexchange"-like URLs.

No, it cuts it down from many many numbers (2 numbers per driver/passenger pair) to 1.

I love how he keeps coming back to how the drives were sourced through retail channels - wtf does he think consumers get them from? I frankly don't care if one brand lasts longer when handled with white gloves, because I'm not going to be paying someone to pretend to do that for me.

Also, insisting that Backblaze has some ridiculously out-of-this-world "workload"? We're not talking a database, but an operation that is usually done with tapes. According to him, consumers must only need 4TB drives with 1000 hour MTBFs and 20TB of lifetime IOs.
True, techs are often nerds, but not always. Look at someone like Larry Ellison, or a lot of startup founders, etc. Also, look at how FOSS was created - by nerds. So, nerds can organize socially.

There are unions for cinematographers and editors in the media. Those are two terribly "nerdy" jobs, and the people who do them are, honestly, huge nerds.

Musicians have a union, and a pension system, and generally do pickup work rather than working for companies. And the musicians in that union are quite a mix of people ranging from "alternative" people (aka, cool nerds) and classical musicians.

Dressing is not important. Business casual is good enough unless you're working in an orchestra. You can be professional in jeans and short sleeved shirts. Most physicians in the ER dress casual.

Your comment about "artisinal grilled cheese" earned my upvote. Who knew such a thing existed? Better yet: why?
With respect, the very people you are covering for a living probably find that signature obnoxious. Speaking for myself, I certainly would; I never thought I'd see an e-mail signature worse than a paragraph of unenforceable legal disclaimer, but alas, I have.

One thing you've probably overlooked is that a significant majority of mail agents (a) discard HTML, making your carefully-formatted signature render in ways that you have not anticipated or dropping it altogether, and/or (b) do not thread and hide quotes the same way yours does. In addition, you're now making me download and potentially display that signature every time you reply to me. On mobile, this can be a big deal in a deep thread where 70% of the data in a message could end up being your repeated signature.

I'm assuming that your workflow is top-posting and letting Gmail hide the repeated signature from you. That gets really unworkable, really quickly in any client that is not Gmail, particularly with a huge HTML signature that is repeated on every message. Since one of the primary topics of your publication is engineering types, you might find that this signature is doing you more harm than good with them. (Though I grant that you probably correspond more with PR and management people, who love Comic Sans signatures.) I don't think your A/B testing can account for that. There is a far better solution in Gmail's canned responses, which really should be promoted from a fucking Lab already:

http://www.wikihow.com/Use-Canned-Responses-in-Gmail

The other thing you probably haven't accounted for is that I very quickly pick up on someone being annoyed that I've e-mailed them. Your signature basically says "you are an inconvenience to me," by demonstrating that you've put a lot of thought into lowering the questions that you answer. I feel the same way about "Before you e-mail me, please read this:" and the other things overworked e-mailers ask me to do as a method of transferring work. I generally end up in a "oh, you don't want me to e-mail you? Okay!" attitude when dealing with this sort of thing.

The signature lightly betrays that you do not generally value engaging with the people that e-mail you and turns me off to you, which might be hurting you with sources. We all hate e-mail, yet the best e-mail correspondents find ways to manage the workload without betraying that their conversational partner is an inconvenience to their life. Seeing as dealing with people via correspondence is probably half of your chosen profession, I'd hope that's not the message that you intend to convey.
You are right. Mobile version did have a bug, hiding the navigation bar! Thank you for noticing! We will fix it asap!
I'm really not sure where these comments are coming from. I use dozens, maybe hundreds of different web services, and I have had every single one go down on me at one point or another except for Google services. This is the first Gmail outage I've ever seen, and if they stay this infrequent (10 - 30 minutes per ~5 years or 0.000011% downtime) at this price, I'm totally fine with that.

Now, Google could be better about this. It's the implication that they're somehow not good in the first place that's so off-putting.
SpaceChem is one of my most-used examples for "this is what happens when you take a game mechanic and optimize it to infinity". Amazing depth and complexity and a really long play-through that stays interesting. And then that leaderboard pops up and makes mockery of your past hour of work, egging you on to beat the curve somewhere. I love it.
I don't know what you or the OP are thinking of, but it's worth pointing out that the placebo effect is not just a phenomenon in the patients' minds; it can also be a phenomenon in doctors' minds.

In brief, any time you have a subjective measurement (for instance, the experimenter assigns a number from 1 to 5 based on how "distressed" the mice -- or human patients -- look), that subjective measurement can be subtly biased. So if the experimenter doesn't blind his experiments properly, you can see a placebo effect in animal studies.

It is appropriate to refer to these studies as double or triple blind because the single blind usually refers to the patient.

Single blind: patients do not know which group they are in
Double blind: experimenters do not know the group identities
Triple blind: overseeing committees do not know the group identities

So animal studies can be assumed to be single blind by default, and become double-blind when the experimenters do not know the group identities.
Rather than barriers - create talent tiers, and have professional associations control the tiers and education.

Meritocracy is a lot messier in real life. More the reason to have that rug up and practice that belief within your own organization.

Schools used to be thought of as parent-substitutes of sorts in the past. In loco parentis was used to refer to this idea. Women would be subject to curfews for example and so on.

The idea is really about what she expected her school to be -- a welcoming community that will help her grow or something of that sort (she took the marketing flyers literally). Was she naive to believe that? A lot of young people make that mistake. Some from affluent small town communities have not had to deal with large bureaucracies before. This is their first go at it.
What you wrote was the public school history book version. X gave Y reasons to do Z. The details of what happened are important. The Great Depression was not aww shucks bad luck, it was a self-inflicted wound. Many of the fixes tried were also self-inflicted wounds.

The rhetoric is toned down. The present political situation is unstable, and unstable situations are ripe for demagogues to take power. I fear that the expanded interstate commerce clause is our Treaty of Versailles. If we do not build a country to be proud of, someone will slap a few runes and occult symbols on the Flag and say "Here is something to be proud of." And the crematoria will run night and day.

Relocation for a startup? If your startup employer fails, you are stuck in a city far away from your support network. If you chanced a startup in the city you lived in, at least you could recover quickly, get a new job, whatever.

Relocation can work well for more established companies (and even then, two body problems often kill that), but it doesn't make sense at all for a semi-risky startup.
This is exactly how it works. And a lot of apps use this JS bridging technic to make their app easy to maintain. Dirty hack becomes technical debt

After a few months dealing with a system that's built on Mongo ad the data store, I've come to the conclusion that MongoDB only use cases are:

1. A persistent cache, or a compute-ahead read-only data store.
2. A write-only store for high volume but non-critical data, such as comments, log events, etc.

MongoDB should never be the primary source of truth data store. Nothing can replace a relational DB for that purpose, yet.
In fact, may colleges make this a core tenant of their sales pitch... "We're a community here, you're not a number! Small class sizes! Professors get to know their students! The Dean gets breakfast in the dining hall with the freshman!" etc. etc.

Yes, Facebook is profiting from my clickstreams. In other words, it's benefiting from my "work". But I'm also benefiting from Facebook. The only reason you use Facebook is because it adds value to your life in some way right? So to me, having Facebook around is mutually beneficial.

Frankly, I get the point the author is making. Personally, because I'm benefiting from Facebook's existence, I'm fine with them profiting from my contribution to the social graph.

Data-storage stickler, indeed. He has been in the storage industry for barely over a year, with no achievements of note. Before that he was a restaurant manager. He's not just making an appeal to authority, but an appeal to risible authority. Whatever the flaws in Backblaze's data might be, it's still data and that wins over completely empty blathering.

As someone who has been touched by suicide, I really feel for this girl.

However I find it puzzling that this story is all about Yale and the expectation that Yale, a for-profit corporation, is required to replace the matrix of her family. The story does not once mention her family. Oftentimes, details are omitted from a story in order to slant opinion in favour of the narrator. I hope that is not the case here.
> 1. A persistent cache, or a compute-ahead read-only data store.

Even then, you're probably better off with Redis or memcached.

Just write to disk. It's very hard to beat flat file text for this use case and most of the time it's not worth it.
If we actually want to "nip it in the bud," shouldn't we be talking at/about/towards the men who groped and insulted her ? That's the actual bud here, right? Why are we all trying to police her behavior instead of the men who attacked her?
Please. I know activists like the Google bus protesters. I'd call them protest enthusiasts, and usually less than half work for professional activist outfits. Most have regular jobs and just love to protest.

I had very good support for mental health troubles at NYU. I never harmed myself, so it is very possible that I would have had a different experience in this student's shoes, but it did wonders for me to feel cared for. I can only imagine how terrible it would be to have a support system open up from under you.
Cryptsy sounds pretty shady (coins disappearing, inept operators)
Submission karma is utterly worthless. All it means is you submit tons of shit, by hand or by bot. In the last year or two there's been a handful of accounts that made the Leaders list [0] by auto or mass submitting generic tech sites (techcrunch, ars, wired etc... really "safe" stuff), even a couple of company spammers were on it at one point! There's no way to win that contest, but more importantly it's not a measure of anything valuable.

Comment karma is worth paying attention to because it doesn't hinge on being the first to submit whatever AOL just shat out.

This is all great, but if you're building a company focused on earning money by doing sales (especially one that has you interacting with other tech companies), the amount of clients you can meet face to face in St. Louis (and the size of the deals) is not something I'd suspect to be competitive with what you'd find in SF.

>As nickpinkston said, those are economies of scale, which is a related concept, but not the same.

This is still network effects, just with two different parts. The drivers benefit when there are more users, and the users benefit when there are more drivers. It falls clearly into the definition of network externalities when you take the drivers into account.
Idk about the pricing but can you use all that bandwidth in a reasonable time period?

Can DO's pipes handle a sustained load of whatever a 16core 48gb ram machine can handle without their pipe being the bottleneck?

If not maybe that is part of the reason AWS can charge so much for bandwidth.
I thought the point about which version chassis the drives in to be a valid point.

I believe the backblaze design has 1 pound drive vibrating at 120hz or so supported by a SATA connector. I don't know the SATA specification, but I suspect they aren't designed to support the drives weight. If SATA connectors where designed to support the drive they wouldn't be plastic.

Additionally the SATA Multiplier boards (thin fiberglass with delicate traces) are supporting the weight of 5 drives each.

This would also explain why the enterprise drives (typically heavier, more platters, and with a more conservative design) are less reliable then the consumer (with typically higher density platters).
Well submission and comment karma are the same karma on HN so it's hard to tell them apart the only other factor you can look at that might be reasonable or a popularity contest is the average as I believe that only pertains to comment karma.
