Using bitcoind:
./bitcoind getblockcount
=> returns something like 258345
./bitcoind getblockhash 258345
=> returns the hash of the latest block like 000000000000001bca1bfe721ecf4fb6480835d966762bc840689ed86642c7b6
./bitcoind getblock 000000000000001bca1bfe721ecf4fb6480835d966762bc840689ed86642c7b6
=> returns the block in JSON format
Another possibility, use my service: http://coinplorer.com/BTC ; I'm currently improving the importation delays and will soon offer a push API to be notified of new blocks (websockets).
Coinplorer importation status can be found here: http://coinplorer.com/Console/Status2, updated in real time (but still some delay between importations, will be solved very soon).
If the blockchain changes (because I don't wait for the confirmations to come), the previous blocks gets deleted and replaced by the new ones!
Topic: Latest block hash (Read 920 times)
You can get it out of bitcoind and bitcoin-qt.
New blocks are found *on average* every 10 minutes - but I've seen it take an hour or even more before for a new block to be found (so probably nothing going wrong at either site).
At other times you might see as much as 6 new blocks found within 10 minutes.

The same, the latest block there seems to be from one hour ago, not from ten minutes ago...
Wait, maybe it is because only after 6 confirmations it gets likely for it to persist in the blockchain. Is that it?

You don't use blockchain.info for that?
Is there any better than blockexplorer to keep up to date with the latest block hash. I find blockexplorer to lag a lot in having updated data.
