i have been working oracle db long time , have been storing dates without bothering timezone. have issue client , server in different timezones , need perform date/time conversion according timezone. has opened lots of questions now: should store date/time along timezone or not? asking because if servertimezone changes data corrupted. if oracle db server located in particular region should run on local timezone? there standard this? my second point in relation dr database servers located in different regions have same data prod db. if timezones not same both db in trouble. to able show clients date in timezone need offset. example, server runs in edt , saved time years. data saved way. so, need create field, store offset each user. need apply offset each date/time field on select. how this, have no idea - because have no idea how use data. select statement, report, or website? if application, client load user info including offset. example, user in edt have offset ...

i have inherited legacy c# & vb.net project have maintain , augment how. there no interfaces , no dependency injection. the first thing thinking of doing creating interfaces , adding ninject, make possible unit test project eventually. is idea or should leave alone ? what best practices implementing di when comes legacy projects. thanks i don't think there's set best practice, other use common sense - it's kind of case case scenario. few important questions ask yourself: how effort going required create interfaces current classes? how additional effort going required write proper unit tests? these unit tests add more value time spent? how long legacy system going maintained? there's nothing worse doing huge upgrade (requiring testing not development staff, product user) replace in 18 months. also, how long has legacy system been in place without issue? there's no reason invent work if appears stable , has low maintenance.

i have column contains bunch of text. way can view in standard tiny cell. is there way automatically expand cell size of text? is possible in 'edit' mode well? this has got nothing sql or t-sql, per se. function of whatever user interface using display query results. assume in case using sql server management studio (ssms). don't believe there way automatically expand columns fit largest value width. might want try sql server development tools (ssdt). although don't think either. option might send results text file (which option) , viewing file in editor. you write own user interface want do.

microsoft's documentation on varchar(max) data type: "variable-length, non-unicode string data. . . max indicates maximum storage size 2^31-1 bytes (2 gb) . storage size actual length of data entered + 2 bytes" http://technet.microsoft.com/en-us/library/ms176089.aspx i thought 2^31 bytes = 2 gb, not 2^31-1 bytes = 2 gb. wrong on point? two of bytes reserved column overhead, question becomes: how many characters data type store? a) 2^31-3 = 2,147,483,645 bytes = 2,147,483,645 characters b) 2^31-2 = 2,147,483,646 bytes = 2,147,483,646 characters the number 2^31-1 0x7fffffff in hex. it's largest possible positive 32-bit number on twos-compliment machine (like x86 , else). the documentation telling maximum storage size, has hold length of data plus 2 bytes. means maximum data size 2^31-1-2, or 2,147,483,645 (0x7ffffffd).

it seems though gap detection picking whatever set timedifference , doing every interval based on that. so here's explanation of data structure , i'm after: i have database that's set this: (schema name) historical -cid int uq ai nn -id int pk -location varchar(255) -status varchar(255) -time datetime my data comes in looking (example 5 rows selected id) 433275 | 97 | mylocation | ok | 2013-08-20 13:05:54 433275 | 97 | mylocation | ok | 2013-08-20 13:00:54 433275 | 97 | mylocation | ok | 2013-08-20 12:25:54 433275 | 97 | mylocation | ok | 2013-08-20 12:20:54 433275 | 97 | mylocation | ok | 2013-08-20 12:15:54 in case above you'll notice i'm missing data 12:25:54 -> 13:00 id 97. trying write report tell me the: start of downtime, duration of downtime, , end of downtime (which i've been handling in php adding timediff time) here's code (php -> mysql) (non-working) stands now: ...

this question has answer here: difference between head , master 3 answers i using git inside eclipse. can please explain difference between head , master[branch] in drop down menu selected? choose 1 arbitrarily , far arbitrariness hasn't appeared make difference, sure that's gonna come haunt me if don't figure out soon. head not pointing master in circumstances. there projects without master branch example, put head pointing somewhere else, or might have master, not default anyway. your confusion may coming general scenario when there no difference between two, there situations aforementioned when not hold true. hope helps.

i have c# code works in visual studio 2012 use visual studio 2010 on same codebase. there preprocessor directive or conditional can use isolate code? no built in pre-processor directive far know, there msbuild variable. open project file (unload in solution explorer, click edit) , add following after main set of property declarations. <propertygroup condition="'$(visualstudioversion)' == '10.0'"> <defineconstants>$(defineconstants);vs_10;</defineconstants> </propertygroup> <propertygroup condition="'$(visualstudioversion)' == '11.0'"> <defineconstants>$(defineconstants);vs_11;</defineconstants> </propertygroup> you can use vs_10 (vs 2010) or vs_11 (vs 2012) preproc directives.

according white paper vmware has published, binary translation techinology used in kernel (ring 0 codes), ring 3 code "directly executed" on cpu hardware. as observed, no matter how many processes run in guest os, there 1 process in host os. assume guest ring 3 code run in single host process context. (for vmware, it's vmware-vmx.exe). so question here is, how execute many ring 3 code natively in single process? considering of windows exe file don't contain relocation information, cannot executed somewhere else, , binary translation not used in ring3 code. thanks. let's talk vmx , intel vt-x 's design. intel vt-x introduces 2 new modes solve problem: vmx root mode , vmx non-root mode , host , guest respectively. both modes have ring 0~3, means host , guest not share same ring level. a hypervisor running in ring 3 of vmx root mode , when decides transfer cpu control guest, hypervisor lanuch vmlaunch instruction, allows transfer vmx non...
