From the Omega paper (section 4.2): Mesos achieves fairness by alternately offering all available cluster resources to different schedulers, predicated on assumptions that resources become available frequently and scheduler decis

Actually, I think Google Omega is the next-generation scheduler after their original Borg scheduler, which in-turn inspired Mesos. The design of Omega is quite different than Mesos. I really do recommend reading the Mesos & Omega papers

by hendzen 13y ago
It seems to partially duplicate the functionality of Mesos, as they are writing their own task scheduling framework [0] based on Google's Omega [1]. The Omega authors claim that Mesos' system of application specific schedulers acc

At this rate we should be expecting a Troubled Angel Relief Program in 2-3 years.

The Snowden documents (that have been released) were actually very light on technical information. The real details of how BULLRUN works are probably compartmentalized to a very small group of people and not accessible to a random sysadmin.

Not going to happen. The WoT is a usability nightmare for the 99.9% of nontechnical users that don't care about things like 'p2p' & 'decentralized'. Do you really think Granny is going to be happy with the table

I wouldn't say it fits the technical definition of a Ponzi scheme. Now, the technology (the opensource daemon, and the network of nodes running it to create a peer to peer ledger and all that jazz) is really an quite interesting experi

To respond to one of your points: > The current best solution is a dedicated cold storage computer (or Raspberry Pi) running Armory, and to make multiple paper backups and store them yourself in various locations, so that it's unl

This is a frequent point that comes up from people who haven't really thought through all the details of how PoW based cryptocurrencies work. A good proof of work function needs two things (among other desirable properties I will elide

They have a "starving hacker" option for 3.50 a month. I think it is worth it for the high quality of content (without annoying ads). They have some non-subscriber articles you can check out to get an idea of the quality.

Perhaps contact the MPAA or RIAA? They provide this kind of stuff to Youtube, Dropbox and other large providers.

Regarding raw addresses, I would encourage you to look into the payment protocol (BIP70). Once that is widespread (it is already implemented in some wallets), the average BTC user will never have to worry about raw addresses, without the do

Agreed, this is a very fragile heuristic. The blockchain exists for a reason folks.

You can broadcast a valid tx that depends on an unconfirmed valid tx that was already broadcasted. The second tx will only be confirmed if the first is, this is how betting sites that accept 0conf txs (such as SatoshiDice) work. Not sure if

As you said, even if the original tx has propagated, a double spending tx with a higher fee will jump the line in a miner's mempool. Never assume miners are altruistic - they seek primarily to maximize their profit. Propogation is a us

Awesome. Now to see how their integration works with regards to confirmation time. The best solution IMO is to use a risk analyzer to determine the number of needed confirmations. 0 conf for small payments for a merchant with a low fraud ra

In practice it is better to build p2p systems under the stronger assumption that actors need not be economically rational. Otherwise the market could be attacked (say by a nation state that wants to kill it) by repeatedly building up rep, t

Fun fact: the original Satoshi bitcoin code included a partially completed distributed market system. Check out the file market.cpp in version 0.1.0. That said, some major challenges (I've done a bit of thinking about this) - First: Sy
