what definitions of fine-grained , coarse-grained timeout? i googled them, properties lectures , academic papers. still don't know mean. tcp uses estimate of round trip time (rtt) guess when packet has received other end. if timer exceeds, packet assumed lost , retransmitted. in tcp reno rtt computed using coarse-grained timer. means that, say, every 500ms checked whether sent packet received or not. if is, rtt time of timer, if not timer checks again in 500ms. of ourse, 500ms arbitrary value how works. tcp vegas, example, uses fine-grained timer, using system's time @ point of sending , point of receiving segment compute rtt. see rfc 2988 details.

given mysql database, how obtain list of table names ordered foreign key dependency can delete each table? understand foreign key's stored in key_column_usage table i'm not sure if there utility method obtain table names in correct order. prefer 100% sql solution. if foreign keys follow naming convention (as should :), simple like select table_name, group_concat(distinct constraint_name order constraint_name) fk_list information_schema.key_column_usage constraint_name rlike 'fk' group table_name order fk_list, table_name; or, if foreign keys don't follow naming convention, then select table_name, group_concat(distinct constraint_name order constraint_name) fk_list information_schema.key_column_usage referenced_table_name not null group table_name order fk_list, table_name;

background: using stored procedure below retrieve hourly time series data. select * ( select cast(localdatetime smalldatetime) [datetime], datavalue, variableid datavalues siteid = 2 , variableid in(1,3,30) ) tabledate pivot (sum(datavalue) variableid in ([1],[3],[30])) pivottable order [datetime] usually data written database @ top of hour, , stored procedure executed @ 5 minutes past hour retrieve existing values. the problem data retrieval on top of hour fails 1 of many sites , no new data written datavalues table site. however, recent hour still present in datavalues table because other sites wrote values it. results in query result has record recent hour fields null . code handles query results can deal hourly data null whatever reason except in cases last record null fields. question: there simple way remove last record of query result (once pivoted per procedure above) if fields of record null ? you can usin...

currently in django app, have 2 kind of users, usertypea , usertypeb. at point, redirect both of types /usercheck/ has function check type of user, , redirect them accordingly. working out pretty well. however, curiosity, if write decorator put ? one place can think of settings.py decorator output different login_redirect_url based on user type. it learning. current implementation working out pretty far. thanks lot. settings.py meant global static configuration data, not try dynamically changing settings. there many other places in django login url can set explicitly. i'm not entirely clear on want do, sounds user_passes_test decorator you're after. the docs : limiting access logged-in users pass test: simple way run test on request.user in view directly.... shortcut, can use convenient user_passes_test decorator.

we have web flow, , @ end can tell there error processing transaction. want add functionality end of flow, natural end-state, lets user click edit button go to, say, step 2 of flow re-enter details. can done? way see make current-end state regular view-state transition state 2 on click of button, end-state makes lot of sense since want clear details of transaction. can me line thinking here? adding decision state before end state work ok. test can made see if transaction went ok, , depending on either go end state or previous view: <decision-state id="checkiftransactionok"> <if test="service.istransactionfailed()" then="previousviewstate" else="endstate" /> </decision-state>

currently using following (works in both py2 , 3) if isinstance(string, bytes): string = string.decode('utf-8') however, there better way both python 2 , 3 compatible. seems missed obvious. in python 2 simple str(string) edit: context : making library/util class accepts redis client object. object has option automatically decode responses (default off), or return plain bytes. given response object, can either bytes or str depending on how object configured the best way avoid problem in first place. use "unicode sandwich" technique - convert data strings after read it, , convert bytes when need serialize it. if this, shouldn't end object might strings or might bytes, shouldn't ever need detect whether has been decoded yet or not. if really can't reason (if third-party code hand either based on conditions don't control), next easiest thing use library six , makes easier write code works in both python 2 , python 3. among ot...
