i can imagine reasons why apple would want or need to be able to update secure enclave firmware without the correct pin entered first. #2-3 are highly speculative: 1) fear of a bug. just the right firmware bug and you have 100 million pho

I don't understand. Can someone please clarify for me. They physically have the phone right? Could they not just read the whole flash, try a pin, write back the whole flash, repeat? (i.e. take the phone apart) (given it is a 5C wit

you are correct, that's not in 2.8. might want to follow this jira: https://jira.mongodb.org/browse/SERVER-11500 that said it will be a big release in other aspects, with pluggable storage engines now, and WiredT

please tell me most people aren't this silly when they interview folks. have the carpenter build something (of trivial scope) while you watch. somewhat analogous to coding on the whiteboard in the interview. come to think of it, it might b

SSL support is in the free distribution but you must built it yourself. One reason would be export controls; another is that creates a dependency on the SSL library for those who don't use SSL, which we found awkward (especially if doing a

re #2: looking at the source code I don't see this behavior. Perhaps in a version from the past? Anyway, please advise or point me to a jira... In src/mongo/db/db.cpp I see: void _initAndListen(int listenPort ) { ...

can you create a Jira ticket for #2 if that is happening it should be easy to fix. jira.mongodb.org

it seems to me that the exchange adding a small random delay (say 1ms) on message reception would dampen the benefits of speed and then there would be less work invested in saving a few microseconds here and there. you still have program tr

Goal 1 of the financing was funds to accelerate r&d, to hire engineers to do things like the ones you mention above; in addition more r&d just pushing hard to maximize overall product quality, stability, etc. not sure if those exact

I imagine Knuth's first version of Tex was pretty darn fast even without 'optimizing'.

I've been an entrepreneur a long time and my take is: 1. Not a myth! Apple, Microsoft, Yahoo, Google, Facebook, Foursquare, ... There are counterexamples but certainly plenty of young ones. I'm 40+ now so no bias. :-) 2. Correct, myth. I

Seems to me comparison to C++ might be more interesting. Wonder how that would be given there are 'growable arrays' and such. There's better (not perfect) safety given scoped_ptr, string classes, etc.

consolidation of adjacent btree nodes after key deletions when appropriate. arguably should have already done this, but it's there now!

development agility is a goal of the project too, in addition to scale-out. i've seen a lot of happy users with a single server (or two) and that's all they need.

Single server durability is coming, v1.8 in the fall. We chose to prioritize some other things before that. http://jira.mongodb.org/browse/SERVER-980 We've always clearly said don't build a bond trading system with it. Our philosophy is

Perhaps a better solution is to make trains more cell-based. (Think ATM.) Each "car" holds just 2-4 people. they run on the tracks and switch on and off at the right stops. Very granular. But still like a train in that you have tracks an

That's fascinating. Add 3 hours as lots of the developers are on eastern time. So that explains the smaller dots as 9 (lunch).

The real question to me is : why in the world are y'all still using C? C++ is just as fast if you don't jump the shark.

by dm_mongodb 16y ago
I don't fully understand the question : why is Windows C++ different than C++ on other operating systems? C++ is great. I really like the control it gives one over initialization at construction and scoped destruction. It's pretty safe th

fwiw, here is the formal version of the theorem from the gilbert/lynch proof paper: Theorem 1. It is impossible in the asynchronous network model to implement a read/write data object that guarantees the following properties: * Availability

Correct - MongoDB project was started by ex-DoubleClickers. DoubleClick doesn't use MongoDB (afaik). My understanding is that it is switching over gradually to internal google infrastructure services - so presumably bigtable like things, an
