i have java 3 strings. let example. string test = "hi, "; string test1 = "this "; string test2 = "java programming!"; i wanna combine 3 string , change md5 format. how do? use messagedigest class 1 string have no idea how append 3 string before change md5. , wanna change md5 string. need external library. md5 not format, or encryption algorithm. md5 hash function . means, long text short digest - apart of short inputs transformation lossy. in general, there no going md5 plain text.

i using sp_executesql pass complicated selection few parameters. slower doing way taking out of stored procedure , declaring variables. i have seen many questions sql parameter sniffing , scenario sounds case. after calling dbcc freeproccache or amending outer select option (recompile) still uses different , inefficent execution plan compared writing same query outside stored procedure. however still using stored procedure setting copies of parameters local variables use efficent execution plan. does scenario rule out sql parameter sniffing cause? becuase recompile query surely there no pre existing execution plan uses. if possible other reasons behaviour? just give idea of sql query can see below (messy generated via entity framework). fast query when put sp_executesql proc variable taken out , put in parameters generates inefficient execution plan declare @p__linq__0 int = 2032 ,@p__linq__1 uniqueidentifier = '8cc161fc-b8de-4746-ba4f-62fa55df26de' ,@p__l

i tried read dicom file using gdcm library using code : gdcm.imagereader imagereader = new gdcm.imagereader(); imagereader.setfilename(@"e:\sample_success.dcm"); if (!imagereader.read()) throw new exception("cannot read dicom file!"); for "sample_success.dcm" file, can read file fine ( sample_success.png ). using "sample_failed.dcm" file, gdcm throws exception because couldn't read it. tried open file using other dicom viewer such radiant , worked. there wrong gdcm build? why cannot read it? i use gdcm 2.6.5. please find both samples here. you're file contains garbage (bunch of binary 0) after offset 0x1480aa (somewhere in pixel data attribute). did expect toolkit if not report error ? by design gdcm still load whatever can until error. if remove new exception in code, can decide (for example) pass imagereader.getfile() gdcm::writer , rewrite file clean dicom. as side note not have access radiant software find

i've created google sheet accepts input user, based on information, goes external website , automatically populates spreadsheet. my problem want hand on google sheet , allow others use it, contains own personal api key external website. unlikely users own api or know how/where put if do. i want allow them use sheet, not able access or see script, or @ least api key within script. because sheet requires input, permissions must allow them edit...and therefore, see/edit script well. part of tos of external website requires registered api key in order pull information. can let use information when use application contains key, not allowed let else know actual key is. suggestions? you should create google script doget method , publish web app. here can put api key , pass user input parameter. the google sheet can call script , api key not exposed end user. web app can connect external api , return results sheet.

since firebase replacing gcm, asking myself how longer google support gcm? in short: when end of life/support of gcm? as of right now, there still no official date when gcm officially deprecated. seen in gcm faq : is gcm going deprecated? we continue support current version of gcm android , ios sdks because know lot of developers using gcm sdks today handle notifications, , client app upgrade takes time. but new client-side features added fcm sdks moving forward. encouraged upgrade fcm sdks. seeing there still lot of developers still using gcm, i'm pretty sure support still continue quite time. however, if intend make use of push notification, highly suggest proceeding fcm. saving hassle of migration in future (not it's hard tho) , make use of new features available.
