Spatio-temporal only means 4 dimensions at most I would think.

They give a time for 4.5 Million objects (not sure what that means) as 3.5 minutes. I've already personally been able to rasterize gaussian filtered kd-trees at a rate of 10 million in a few seconds.

Cool game! I was able to build my first code in just minutes even if my Joe Rampage got pretty badly beaten up.. need to take another round of practice...
Why is that insane? It's inelegant, but it's not functionally different than having an API and a system for registering API keys. Either you trust the aggregator or you don't; if you don't you shouldn't give them access to your data either way. If they do something they shouldn't with your data, they'll be ruined if it becomes public.

(Of course there's a huge gray area of things they could do that you wouldn't like, but that would't ruin them. But there's a clear difference between questionable things, like selling your data to advertisers, and completely not-ok things, like stealing your money).

As someone who has looked heavily into this option, I can say that you are drastically understating the simplicity of this option.

Getting a second passport takes significant time and investment in most cases.
Don't let success stories from HN fool you. Your chances of having a side project provide a reasonable lifestyle in the short term are incredibly low.

I would recommend option #3: switch jobs to one that has a more reasonable work/life balance. Then use your free time to work on the side project to the point where 1) it could support you, 2) you could get angel funding, or 3) you validate the null hypothesis that there is not a business there (but still get a great resume line out of it).
It's most likely due to my last paragraph and not the follow up question itself. :) Don't worry about it.

I agree; the goal should be indeed improving the net positive contributions to people’s lives. I was happy to find out that there is some work directed at designing products for human values; see Tristan Harris's project, "Time Well Spent":

If there were some significant energy flow back up the continental slope, someone would have noticed it by now. The only thing I can think of is sperm whales' predation of squid, but even squid are more pelagic than benthic. The pressure at depth keeps gases in solution, so they're probably not going anywhere either. What else could there be?
Oh, interesting. We use this to segment between individuals/consultants and businesses.

Jim Rizoli Interviews Germar Rudolf
This leads to an opening for either a challenger to Mint that has better relationships with the banks, a bank with a better UI than the existing banks, or a bank that explicitly supports Mint.

The existing banks burying their heads in the sand when there is obvious consumer demand makes the area much more ripe for a new entrant. I'm not sure how it will play out, but I would consider switching banks in order to have a better UI on my money. Supporting something like Mint or Personal Capital is basically a requirement for me to put my money in your bank.

Note that I'm not even particularly happy with Mint, I just can't imagine not having some form of aggregation of my financial life. I probably check it at least 1-2x a week and have been for 5+ years, it's a critical piece of software for me.
Honest question, were there robber barons besides the famous ones in the US?
I was wondering the same. This could potentially allow for circumvention of their usage limits though.
What's the problem with document databases, really? To be honest, for 80% of the projects I've ever worked with, fixed-schema rdbms's fitted just like... a square peg in a round hole!

Heck, even for advanced analytics, I find mongo aggregates and mongo map reduce 10x more intuitive and SQL that inevitably ends up using zillions of non-portable tricks, stored procedures and god knows what. And atomicity and whatever else transactions guarantee you in theory can be easily emulated with some good db structure design tricks and app design tricks in practice.

And the smarter a RDBMS is, like Postgres, the more dangerous it becomes for maintainability: it's a zillion times easier to maintain 'logic expressed in app code' (because you have basic stuff like version control, tests and so on), than 'logic trapped in the db' (good luck explaining to a new developer how "X automagically happens because of trigger Y and stored procedure Z, so there is no app code for X that you can instantly tweak to change how it works"). This is why I at least have some respect for mysql: it's retarded enough that it forces you to put the login in the code, where it f belongs!

Really, give me a dumb document db like mongo any day! And if I want something "less dumb" there're things like arangodb and rethinkdb that can also do joins and graphs. And there're also "true graph-dbs" for index-less "joins"/traversals, like neo4j and orientdb, for when the relationships for when you actually end up doing more than 3 to 4 levels deep joins...

Imho the development of "high-end rdbms" like postgress and oracle has been a huge waste of human brainpower and all the benefits supposedly provided by these pieces of technology were actually from the clever app-level code that mostly worked around their inappropriateness...
Exactly right.
Inncubator in Palo Alto (Hacker Home) Invitations Open
Shit that's cool. Could see that saving us so much time in our workflows.
A couple years ago I found out Google was already using 8TB+ drives in production before they hit the wide retail drive distribution market, so I would reckon that many companies with deep pockets and inside vendor relationships would be able to get access to some very high density disks that folks like Backblaze may not be able to get yet. There's also possibilities for better density through solid state that may not make much sense from a raw $ / GB storage basis that drives Backblaze while tiered storage may be essential for how Dropbox operates. Also, I imagine it'd be possible to centralize and strengthen cooling while shoving a bunch of disks into a 4U box to increase raw drive density. For example, you could use a variant of peltier cooling to have drives chilled together off a single metal plate, then repeat a few times in a chassis.

So in short, I can think of improvements but most would come at the cost of higher capex to do so, and that could negatively impact the $ / GB numbers that Backblaze is trying to keep down. Perhaps there's not much consideration for leasing datacenter real estate or power costs or something into the equations but without some reliable numbers it's all speculation to me.
Are you allowed to describe the eviction policy? It would be interesting to know the differences. You can contact me privately (ben.manes at gmail). I'd be interested in knowing,

- Did it use a sketch in a similar manner?
- Was it an LRU window to a classic LFU? Did it retain history?
- Was it robust in all workload patterns or optimized for VDN workloads?

I would expect a 4-Segment LRU (S4LRU) policy to work well in VDN, while being a simple O(1) policy. That's used by Facebook photos, among others, so probably good for CDN content.
Or.... maybe the publicity from the change drew more people's attention to it. If they'd changed it to a moon instead of a star, maybe we'd see the same increase just due to people talking about it so much.
Everyone blames someone else as classified military smartphones lack patches
I don't work at Dropbox, but I do work in storage. I've seen similar systems pack ~250-500TB into a 4U box. 60 drives x 6TB drives = 360TB. Not sure how you would get anywhere over 1000TB with today's spinning drives. There is a vendor linked in Backblaze blog post (45drives) which sells 60 drive enclosures, which they somehow list at 480TB but I'm not sure how the math works out there. However, keep in mind that usable capacity is going to be less. Erasure coding has significantly less overhead than traditional raid, but there is still a cost (depends on chosen protection set).

In some cases yes, in some cases no. The CAD draftsmen at one of the companies I worked at were in the UAW. The older guys made a boatload of money while the young guys barely made made more than minimum wage. On an open market the managers would have happily paid the young guys 2-3x as much for their work, but that wasn't an option.

US tries, and fails, to block “import” of digital data that violates patents
The good thing is that there are efforts to improve ACH. For example the UK already has "Faster Payments"[0]. In the US the Federal Reserve has a task force[1] going to implement fast pay. Sadly it will be a while before the US gets it as they are still in the planning stages for the system. The completed spec is expected by the end of 2016, so we probably won't see it implemented until 2018.

To add, the US is so complicated because we have so many friggin banks. Many countries there are only a few banks the service the nation, while the US has something like 14,000 different banks.

They still have excess bandwidth. These deals will attract customers away from other carriers and there is almost certainly a kickback to T-Mobile by the paid content providers.

T-Mobile is sharp when it comes to making data-driven decisions: look at the profitability of their offerings for people with less than excellent credit--make no mistake, every "uncarrier" move follows from careful number crunching; i.e. creates value both to customers and shareholders.

Good for you. Sailing around the world hundreds of years ago was dangerous. Going to the moon 45 years ago was dangerous, tons of things are still VERY dangerous.

Just because it's beyond your personal level of safety-acceptance, it doesn't mean there are not hundreds of people lining up to do it. You mentioning it's dangerous adds absolutely nothing to the discussion or possible learning opportunities.

All you're doing is detracting from someone who's actually doing something. Rather than being so negative, why don't you go out and do something and document it as well as this guy and share it for everyone like he has?

I honestly believe that "quality" always correlates with personal biases and collective norms.

Even the guideline for posting here - "anything that good hackers would find interesting" - assumes that 1) you should be a "hacker" (a subjective term, especially on a site with as diverse a community as this) and qualifies this with "good" (another subjective term.) Are we to assume that stories which are popular (high karma) are necessarily posted by better hackers than those which aren't? One should post "anything that gratifies one's intellectual curiosity," implicitly provided one has the correct sort of intellect. While this is designed to bias the site in favor of high karma posters (and, obviously, whatever the mods happen to want) the end result is that quality is in the eye of the beholder.

It's all arbitrary and it's all subjective.
Thankfully, the article you linked links to its sources... which don't back up the claims it makes. From the link it uses to say that DNSSEC doesn't help end users against spoofing:

"Although DNSSEC solves many of the security problems with DNS, it is not widely used because of the large cost of transitioning from DNS. However, where available, DNSSEC protects against the DNS attacks in Cafe Crack and should be used by Internet users."

Almost the exact OPPOSITE of the claim.

Of course DNSSEC also protects end clients, because by design the DNS protocol between end clients and servers, and between caching servers and authoritative ones, is the same.

DNSSEC client support is much more widely deployed and activated on servers, but implementations exist for end-user OSes, and that hop of security is clearly the goal here. It's just that no consumer OS turns on support by default, because server-side deployment numbers are so low. And the packages that do exist are a royal PITA to install (in the OSX case) or configure (in the desktop Linux case). (Side note - still no DNSSEC for desktop Windows, according to my latest Google search.)

Why performance engineering is essential to business success
Not sure if everyone on HN is aware of it, but HERE Maps has been supporting offline maps for a while, for Windows, Android and iOS devices. You just first download a package over WiFi to your phone / SD card (one package per country, or for big countries, one package per region) and you can access the maps offline.

That's super useful when traveling within Europe for instance.

The main reason I sometimes use Google Maps is that it has better traffic coverage (shows also minor roads while HERE only major ones).
For a secure protocol just use HTTPS. Secure formats don't really exist for data interconnects, since you'd have to send across enough information to decrypt it, and now we're in the "security through obscurity" territory.

It might sound horrifying but JSON or CSV over HTTPS is the most likely to work and the least work for financial institutions to implement (thus giving them less ammo to fight it on cost grounds).

Services interconnecting is largely a solved problem in general. Banks might have needed better security historically, but these days these services are all fairly secure, so there isn't much bar raising that needed. Heck Apple Pay is basically this system.

Interesting and thanks for the enlightening comments. I proposed similar things to a few people esp the partnership with hardware development, working around faulty (cheap) stuff, custom firmware, and kernel I/O modifications. I expected each of these in a high-end solution.

My architecture didn't have an IP stack at all: guards or front-end acted as I.P. gateway while internally using much simpler protocol that still worked on Ethernet. Inspired by Active Messages and FLIR protocols of past. TCP/UDP/IP is unnecessarily complicated with simpler message passing easy in software and FPGA hardware for offloading onto cheap FPGA's. A side note was using one or more I/O coprocessors like mainframe Channel I/O (see Wikipedia) to get huge throughput might be cost-effective depending on hardware selected. Esp if using embedded SOC for I/O offloading.

Note: Octeon II's can do many Gbps of line-rate processing for three digits and much simpler internally than a lot of stuff.

The SASD project for secure, hard disks also suggested putting logic in the HD or SATA controllers rather than the system. Made me wonder about putting I/O mgmt and most storage logic in custom PCI cards with lots of SATA connectors. Basically, embedded systems enough CPU to manage whatever you throw at them, just running what's good for that layer, and less watts/money than whole servers. Seems like at some point one could port that layer to straight hardware for great performance/watt although high, initial NRE. eASIC can do that relatively cheap, though, with the Nextreme's if a design is FPGA-proven.

That was just exploration on paper so I'm not sure how practical it would be. My focus was high security systems and storage which necessitate better isolation. Hence, PCI cards rather than servers. Interesting that there was a lot of overlap, though, between what I thought made sense and what you all ended up doing. Very interesting. Guess I'll keep proven tactics in mind in future designs.

How? They can only be approved if they're getting paid the same or more than existing software devs.
Banks have been purposefully limiting customers' view of electronic data for years, first by eliminating running balances about 10 years ago and then by limiting online data to 90 days. They do this because confused customers are more likely to pay fees such as overdraft fees, which is where retail banks make most of their money.

Mint complied with the banks' demand to not display running balances but they do display data going back indefinitely in time.

What Mint has shown the banks is how valuable the data is to advertisers. The data is so valuable that Intuit is shutting down their popular $50/year semi-subscription Quicken software in favor of advertising to people via Mint.

In an ideal world a government regulator would step in and ensure data access and privacy. But we do not live in a very ideal world.
