i have field logo=models.imagefield(upload_to="restaurant_detail/restaurant_detail", help_text = "upload restaurant logo") this returns error, data truncated column 'logo' @ row 1 so go ahead fix statement alter table my_table modify logo varchar(500) (i increase characters.) this works everytime reset database have again and when try , execute alter statement above , insert data, still fails data truncated column 'logo' @ row 1 error. how permanently fix without having alter table time? change field definition to: logo = models.imagefield(max_length=500, upload_to="restaurant_detail/restaurant_detail", help_text="upload restaurant logo") i added max_length kwarg tells django how many chars field can store , cause database field created appropriately.

i have imput field in form multiple(two) backgrounds this: background: url(framework/images/search.png) no-repeat 6px 7px, /*this magnifying glass icon - important later */ rgba(200,200,200,0.1); then i've got transition: transition:background 0.2s linear, box-shadow 0.5s linear; and on focus of input field: input:focus, { background:rgba(0,0,0,0.1); box-shadow:0px 1px 0px rgba(0,0,0,0.1) inset; } basically (or should) when input field active background changes darker color transitions. box shadow makes inner effect of inside border. case when background of 1 element (only background color). when added icon on higher layer background wont change, box-shadow works. think browser confused how change color of bitmap image. my question is: there way transition 1 layer of background (address somehow), bitmap image stay same , color change? thank you. edit: jsfiddle -> http://jsfiddle.net/8drtt/ http://jsfiddle.net/8drtt/1/ input:focus...

i'm running code, consist in find average values. in ~6 million lines csv (ssm_resnik.txt), first row 1 reference, second row , third value 'distance' between 2 references. such distances arbitrarly defined biological criteria not important issue. of the references versus... of references, hence huge csv more 6 millions of lines. in csv (all_spot_uniprot.txt) have ~3600 spot's (first column), each of them 1 or more reference (third column). values same of huge csv. need compare each of 3600 of spot ref of second file other 3600-1 ref's in same file. of possible combinations, if exists, in first, huge csv file (ssm_resnik.txt). all_spot_uniprot.txt, each 2 spot ref's serve iterator correspondent reference (in third column) , iterate on huge csv file that, if exists, show value 2 "vs" reference. what problem code? well... 10 seconds each iteration, 3600 *3600 *10 = 129.600.000 seconds = 1500 days (almost 5 years). happens in core i3, in mac. below ...

so have element behind another, it's still visible(its covered partially element itself, otherwise covered margin attribute of element above). want trigger mouse event when mouse over, doesn't passed because of element in front. know how calculate if on , how point it, don't know how send event onmouseover or hover or onmouseout . if helps pointing @ using document.getelementbyid("<calculated id>") . know works because it's id based off of location within grid, have calculate position of mouse , relate grid. also event supposed happen(but isn't because of things in front of it), :hover triggers simple transition animation via css. document.getelementbyid('elementinfront').addeventlistener('mouseenter', function(){ document.getelementbyid('elementbehind').doyourstuff(); });

i trying use c program (via dynamic libraries) python , ctypes module. several constants defined in header file important me, unsure of how enum being used set values. the obvious ones, think understand like: enum{thing1, thing2, thing3}; thing1=0, thing2=1, thing3=3 but, this? enum{thing1=-1, thing2, thing3}; is result: thing1=-1, thing2=1, thing3=2 ? what one? enum{thing1=1, thing2, thing3, thing4=-1} ? i don't have easy way test this, hoping can explain way enum works in context. c books looked in seemed cover either first case or case each value explicitly defined, not mixed case. many in advance! the value of first enum constant 0, unless specified otherwise. the value of other enum constant 1 more value of previous, unless explicitly specified. so enum{thing1=-1, thing2, thing3}; sets thing2 = 0, thing3 = 1 , and enum{thing1=1, thing2, thing3, thing4=-1} sets thing2 = 2, thing3 = 3 (and thing4 = -1 explicitly given).

i want keep track of values of instance variable, , breakpoint starts @ static method. can't check instance variable value. there way that? searched on google, found no clue. is because instance can't accessed in static method? you pass variable tracking method. although make note every time can remove when done testing. but honestly, if don't have access variable within method, won't change time have exited method, unless have multiple threads. therefore, can set breakpoint after/before method called.

git push used push changes remote repository. git diff shows changes made since last pull operation remote repository. git diff synonymously used git patch . after getting difference, patch applied through git am or git apply repository updation. so, these 2 commands fundamentally same or there difference between git diff , git push ? git push push changes made in file repository. last step make add change project. git diff used see changes made different files since last commit. shows line added or removed project. the basic flow goes this. you make changes in project. -> git add -> git diff if want see changes have been made -> commit using git commit -> push committed changes repository using git push . if new git, learn interactive tutorial http://try.github.com/

what happens if there 2 people sending same query @ same time database , 1 makes other query return different? i have shop there 1 item left. 2 or more people buy item , query arrives @ exact same time on mysql server. guess queue if so, how mysql pick first 1 execute , can have influence on this? sending same query @ same time queries not run in parallel it depends on database engine. myisam, every query acquires table level lock meaning queries run sequentially queue. of other engines may run in parallel. echo_me says nothing happens @ exact same time , cpu not @ once that's not true. it's possible dbms run on machine more 1 cpu, , more 1 network interface. it's very improbable 2 queries arrive @ same time - not impossible, hence there mutex ensure paring/execution transition runs single thread (of execution - not necesarily same light weight process). there's 2 approaches solving concurent dml - either use transactions (where each user g...

i spawning processes popen (python 2.7, shell=true) , sending sigint them. appears process group leader python process, sending sigint pid returned popen, pid of bash, doesn't anything. so, there way make popen create new process group? can see there flag called subprocess.create_new_process_group, windows. i'm upgrading legacy scripts running python2.6 , seems python2.6 default behavior want (i.e. new process group when popen). bash not handle signals while waiting foreground child process complete. why sending sigint not anything. behaviour has nothing process groups. there couple of options let child process receive sigint : when spawning new process shell=true try prepending exec front of command line, bash gets replaced child process. when spawning new process shell=true append command line & wait %- . cause bash react signals while waiting child process complete. won't forward signal child process. use shell=false , specify full paths ...
