is there view or other pane see files in project in conflicted state? in projects thousands of files (even after restart of ide, losing console output). within eclipse found show tree conflics command, need, tree conflicts only. i don't use synchronize view, i'm comfortable doing update , handling conflict edit conflicts , mark resolved (i guess that's because started using svn command line). i use svn subclipse, guess common other scms too.

i have created script connect server using sftp. avoid putting password in script plain text, i'm planning on putting in file encoded in base64. can read file no problem. don't know how decode base64 expect. so, now, script reads file , puts password (directly) script. how decode it? i'm ready move script shell/bash if there's way such thing. thank you. here's code: #!/usr/bin/expect set mypassword [open "sftp_auth.cfg" r] set data [read $mypassword] spawn sftp myuser@111.111.111.111 expect "*assword:" send "$data\n" expect "sftp>" send "cd /repository\n" expect "sftp>" send "get example.sh /home/user/example2.sh\n" expect "sftp>" send "exit\n" interact you can use tcl's exec command decode password. example: [step 101] # cat foo.exp set base64_passwd ugfzc3cwcmq= set passwd [exec echo $base64_passwd | base64 -d] puts $passwd [step 102] # e

i have 1 complicated select, fills temporary table ids, based on need create delete query. for example, temp table's rows looks like: - first_id | second_id | third_id - 1 | 222 | 342 - 1 | 222 | 343 - 1 | 223 | 551 ... and query : delete mytable concat(first_id, 'x', second_id, 'x', third_id) in (select concat(first_id, 'x', second_id, 'x', third_id) temp_table); but query long. when show processlist, see query time 4000s. so question is, how can optimise delete query, delete rows 1 table based on select table , delete rows based on 3 keys? you can start removing concat , use join instead of subquery, try : delete mt mytable mt inner join temp_table tt on mt.first_id = tt.first_id , mt.second_id = tt.second_id , mt.third_id = tt.third_id

what difference in using @transactional annotation in domain/service layer , dao layer. provide advantage using in domain layer. it practice use @transactional in service layer because governs logic needed identify scope of database and/or business transaction. persistence layer design doesn't know scope of transaction. daos can made @transactional other bean, it's common practice use in service layer. tend because want separation of concerns . persistence layer retrieve / stores data , forth database. for example, if want transfer amount 1 account another, need 2 operations, 1 account needs debited other needs credited. so, scope of these operation known service layer , not persistence layer. the persistence layer cannot know transaction it's in, take example method person.updateusername() . should run in it's own separate transaction always? there no way know, depends on business logic calling it. here few thread should read where @transactio

problem llc giving me following error: llvm error: unsupported relocation on symbol detailed compilation flow i implementing llvm frontend middle-level ir (mir) of compiler, , after convert various methods many bitcode files, link them ( llvm-link ), optimize them ( opt ), convert them machine code ( llc ), make them shared library ( clang it's linker wrapper), , dynamically load them. llc step fails of methods compiling! step 1: llvm-link : merge many bitcode files i may have many functions calling each other, llvm-link different bitcode files might interact each other. step has no issues. example: llvm-link function1.bc function2.bc -o lnk.bc step 2: opt : run optimization passes for using following: opt -o3 lnk.bc -o opt.bc this step proceeds no issues, that's 1 causes problem! also, it's necessary because in future need step pass passes, e.g. loop-unroll step 3: llc : generate machine code (pic) i using following command: llc -m

i want download svg image in dom. i've searched around on stack overflow , common approach following these steps: serialize svg xml string var svgimage = document.getelementbyid('maskedimage') var svgxml = (new xmlserializer).serializetostring(svgimage) create javascript image xml string source var img = new image(); var svgblob = new blob([data], {type: 'image/svg+xml;charset=utf-8'}); var url = domurl.createobjecturl(svgblob); img.onload = function () { /* next steps go here */ } img.src = url; draw image on canvas var canvas = document.createelement('canvas') var ctx = canvas.getcontext('2d') canvas.width = width canvas.height = height ctx.drawimage(img, 0,0, width, height) dump canvas url , make user download that window.open(canvas.todataurl('image/png')) // not point of question the thing is, svg has <image> tag svg mask (which black , white <image> ). make things worse, 1 of these images has

i want find column indices of numpy array elements of column greater threshold value. for example, x = array([[ 0.16, 0.40, 0.61, 0.48, 0.20], [ 0.42, 0.79, 0.64, 0.54, 0.52], [ 0.64, 0.64, 0.24, 0.63, 0.43], [ 0.33, 0.54, 0.61, 0.43, 0.29], [ 0.25, 0.56, 0.42, 0.69, 0.62]]) in above case, if threshold 0.4, result should 1,3. you can compare against min of each column using np.where : large = np.where(x.min(0) >= 0.4)[0]
