I suspect this is a small demographic - chances are startups don't want to hire people that wouldn't make it through a Google/MSFT/Facebook tech-screen. The people who would make it through are going to demand founder-le

If you're a halfway decent engineer, you can make north of 180k/yr at Google/MSFT/Facebook. You can also do this in a market like Seattle where there is no income tax. Serious question, who in their right mind would tak

This only works when feeding the data forward. When SAT-solving (i.e. working backwards), each clause has multiple possible inputs, meaning there is nothing to resolve away.

Yes, we don't have good ways to unify the flipping between GF32 and GF2 beyond down-converting to GF2 (which yields a massive increase in clause-complexity). GF32 addition in GF2 basically looks like a giant ripple-carry-adder.

SAT solving SHA256 is a dead end - I was researching this for the purpose of Bitcoin mining (before this article came out), along with many others, for profit. SAT solving typically relies on reducing a function down to boolean expressions

People hate math formalism because it only makes sense if you already understand it.

Can someone on a visa switch jobs? In the U.S. changing jobs while on a visa resets the residency process, which indentures the employee to the employer.

One of the first things my representative's office does is ask for my postal code and name. Pretty sure they do check and even cross verify incoming phone numbers. My representative's office once even answered the phone and gree

Also - Cairo/WinFS failed because their requirements were not achievable, and there was no real market demand for them. Just like natural language input for the general market (no one outside of very specific niches actually wants to

The problem with Database-as-a-File System is people are really asking for The-One-Unified schema. The problem with The-One-Unified schema is it anticipates all future requirements which is impossible. At best you can add a few more struct

This ignores the massive body of research and evidence that suggests putting a database in a file system is a Bad Idea. File systems deal with organizing unstructured data (i.e. blocks of bytes); databases deal with organizing structured da

JScript.net has never been a first-class citizen, and Microsoft never really made an effort to make it viable in all of the domains C# is. JScript feels like an attempt to embrace/extend JavaScript that never took hold. The problem is

Well, if it was me... 1. Replace PowerShell with a .Net interpreter so you can "just run" a .cs_exe file or whatever. No one wants to learn/deal with yet another throwaway proprietary scripting language. 2. Replace all the Po

It's more than that - virtually large all datasets I've worked with (> 20B documents) had a keyspace of under 128 keys/columns per nested level of a JSON document. Meaning an optimizing DB could express most keys as singl

by optimiz3 13y ago
Internal pseudo-schematized data storage and JSON support aren't mutually-exclusive. Nice to have a checkbox feature like this but the implementation isn't particularly exciting for large datasets.
438.
by optimiz3 13y ago
This just forces complexity onto the caller - it's not unreasonable to expect the DB to "pseudo-schematize" as most keys will be repeated.

Can anyone comment on the storage overhead of JSONB key names? One of the worst things about MongoDB's BSON format is that 8M instances of the following record: { "user": "test", "isValid": true }

That's what I mean - store the intermediate result of the MD5(key XOR ipad) and MD5(key XOR opad). The only trickery is implementing the HMAC wrapper, but that's not very difficult.

by optimiz3 13y ago
Just looked up CRAM-MD5, and the password is used as a key to HMAC-MD5, which means you can at least store MD5'ed versions of the passwords. Add on a layer of encryption (unique key per password, keys in a separate encrypted table) and

Devil's advocate - most rating behavior tends to be "interrupt driven". I.e. if stuff is working correctly, the user just carries on, but if stuff is broken, the user gets frustrated and leaves a negative review (what else c
