i have cms system using ck editor enter data. if user types in <script>alert('this bad script, data');</script> ckeditor fair job , encodes correctly , passes &lt;script&gt;alert(&#39;this bad script, data&#39;)&lt;/script&gt; server. but if user goes browser developer tools (using inspect element) , adds inside shown in below screen shot when trouble starts. after retrieving db when displayed in browser presents alert box. so far have tried many different things 1 them encode contents using antixssencoder [ httputility.htmlencode(contents) ] , store in database , when displaying in browser decode , display using mvchtmlstring.create [ mvchtmlstring.create(httputility.htmldecode(contents)) ] or html.raw [ html.raw(contents) ] may expect both of them displays javascript alert. i don't want replace <script> manually thru code not comprehensive solution (search "and encoded state:"). so far have referre

my table (@mytable) list of ids start dates , end dates (inclusive) represent interval of days when id appears in file received once per day: id start_date end_date 1 10/01/2014 12/15/2014 2 11/05/2014 03/03/2015 3 12/07/2014 12/09/2014 4 04/01/2015 04/15/2015 each id appears once, i.e. has 1 associated time interval, , intervals between start_dates , end_dates can (but not necessarily) overlap across different ids. need sql query find sets of dates each id appear @ least once when files these sets of dates merged, in smallest number of dates possible. in table above solution these 2 dates: file_date id(s) 12/07/2015 1,2,3 04/01/2015 4 but example 1 date between id(3)'s start_date , end_date & combined 1 date between id(4)'s start_date , end_date solution. the actual data consists of 10,000 different ids. date range of possible file dates 04/01/2014 - 07/01/2015. each daily file large in size , must downloaded m

is leaving debugging code in place discouraged practice? for example, program (written in java) i'm working on can send emails. there various ways emails failed send handled. in method send in email class, pass boolean argument boolean fail which, if true, causes method fail. allows me test whether emails failed send correctly handled. i have other instances of throughout program well. obviously, in final production code program told fail. there harm in leaving these debugging tools in place in case corresponding features ever need changed? rather commenting or uncommenting debugging logic, if can set debugging run based on environment variable, leaving in place practice. come in handy (or else) down road. in future you'd simple set debugging true see debugging logic, , in production, you'd set false.

where start if want learn assembly security reasons? think if want avoid mistakes, best thing know you're doing. happens if cast signed int unsigned int. once got strange error message, variable isn't correctly aligned. @ time had no idea alignment is. my 2 cents unless find assembly intriguing , have lot of time i'd suggest learn these things: how signed number represented, how floating point numbers represented , data alignment is. i suggest learn assembly fascinating recognize huge effort beginner purpose. learn assembly not learning list of instructions, there no need remember such list. learning assembly means learning every aspect of how computer works, starting hardware datasheet how os implemented. lot of material it hard make list of it , let alone learn it! i started learning assembly teen because fascinated it, there no purpose knowledge. did (and do) fun, made things easy, had not deadlines. have plenty of time learn pieces of puzzle 1

i have written many simple guis, worked fine. beginner think way of writing user interfaces not practice. is proper practice if 1 uses more panels desired interface? use of setbounds() method good? the less sub-components use, more responsive ui going be. because has less things deal with. i not recommend using 'setbounds` creates inflexible ui in cases. encourage start using layouts such borderlayout , flowlayout etc. versatile of them miglayout here more general information swing layouts: https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html

i have implemented logic through python functions , looking way calling functions more efficiently. there way calling these functions windows command prompt or python cmd below? python function: def logic1(args) ... want call function this: logic1(args) import file in python console this: from my_file.py import * or from my_file.py import name1, name2 ... now can use these in python console. out same importing files. for calling functions in windows prompt need separate each function own file , use py2exe convert them executables. may overhead of work though, depending on want achieve.

i'm trying run program allow user input both char keycharacter , string thestring. then, using these inputs, mask keycharacter if occurs in thestring "$", remove keycharacter thestring, , finally, count number of times keycharacter occurs in thestring altogether. every method working fine, except method getkeycharacter user has input char: user can enter single letter (e.g. q, or z). if user enters other single letter (which can word, phrase, sentence, special character # or $, blank space or tabs, or pressing enter), program returns user original question asks keycharacter user. should continue looping original question until user enters valid input. since i'm still beginner java , loops weakness far, part causing me lot of trouble. know should using while loop, logic behind nested loops confusing me. from searching possible solutions, know there these things called regex , try-catch exception issue, since haven't gone on explicitly in class, i'd

recently came across app "instant blood pressure - monitor blood pressure using phone aura labs, inc." https://appsto.re/us/jwiyx.i claims measure blood pressure using camera of iphone. use meditation app called sattva can measure heart rate pretty accurately placing finger against camera. although 2 applications doing different things (pressure vs heart rate), how technology work? i doubt can measure blood pressure using camera. pulse different. measures amount of red colour in skin , finds rate @ changes. blood pressure different though. the way measured doctors apply pressure blood vessels , decrease point blood can heard pulsing , again when can't. without knowing these pressures cannot measure blood pressure (by definition).
