One common task in bioinformatics is to align sequences with a program such as bwa and pass the sam-formatted results on to samtools to do downstream processing. The python package pysam helps me do all of the tasks samtools does but within python.\n\nI would like to pass the results from a call to the aligner bwa to pysam without having to write to a file.\n\nPysam allows for you to open Samfile object with the input file being set to \"-\" and it will read from stdin. Similarly, bwa writes its results to stdout.\n\nThe way I have written it thus far is:\n\nbwa_call = [\"bwa\", \"mem\", \"-v\", \"1\", \"-t\", str(cores), index, fwd, rev]\nbwa = subprocess.Popen(bwa_call, stdout=subprocess.PIPE)\nsamfile = pysam.Samfile(\"-\", \"r\")\n\n\nThis seems to work, in that I don't see the stdout output from bwa but the problem is that pysam does not know when the file is finished and so just keeps waiting.\n\nIs there a way in which I can pass the stdout from bwa directly to pysam without writing to a file?"

"How to handle scenarios that \"should not happen\" in Spock?",
"I am wondering what is the best practice in Spock for scenarios that are exceptional or underfined situations. One that should normally not happen.\n\nEXAMPLE:\nLet's say in our API, there are two mutually exclusive fields. When both provided the result of some calculations is undefined, which in practice boils to some arbitrary handling - like giving precedence to one of them.\nOn a higher level that will lead to exception and a proper http response eventually. But in some local (unit) area a piece of code will still be executed against both.\nWhen writing unit tests, I'd like to cover (record) also the current behaviour for this (atm) impossible corner case.\n\nSo far I just resorted to a proper comment, either in the test case name or somewhere else. But the question is: what would be the best/idiomatic Spock practice for documenting those scenarios? I mean something similar using || for separating expected arguments in where clause."

"Can't kill YARN apps using ResourceManager UI after HDP 3.1.0.0-78 upgrade",
"I recently upgraded HDP from 2.6.5 to 3.1.0, which runs YARN 3.1.0, and I can no longer kill applications from the YARN ResourceManager UI, using either the old (:8088/cluster/apps) or new (:8088/ui2/index.html#/yarn-apps/apps) version. I can still kill them using the shell in RHEL 7 with yarn app -kill {app-id}\n\nThese applications are submitted via Livy. Here is my workflow:\n\nOpen the ResourceManagerUI, open the Application, click Settings and choose Kill Application. Notice, the 'Logged in as:' is set to UNKNOWN_USER:\n\n\n\nConfirm that I want to kill the Application:\n\n\n\nI get the following error in the UI:\n\n\n\nOpening the console in Chrome, I see a 401 (Unauthorized) error.\n\n\n\nIf I try this from the old UI I am able to expand the error message and it shows the following:\n\n{\"RemoteException\":{\"exception\":\"AuthorizationException\",\"message\":\"Unable to obtain user name, user not authenticated\",\"javaClassName\":\"org.apache.hadoop.security.authorize.AuthorizationException\"}}\n\n\nI've read lots of posts, verified and changed several settings to try to fix this with no luck. Here are some of the settings I checked or changed as a result of my research:\n\nhadoop.http.filter.initializers=org.apache.hadoop.security.HttpCrossOriginFilterInitializer,org.apache.hadoop.http.lib.StaticUserWebFilter\nhbase.security.authentication=simple\nhbase.security.authorization=false\nyarn.nodemanager.webapp.cross-origin.enabled=true\nyarn.resourcemanager.webapp.cross-origin.enabled=true\nyarn.resourcemanager.webapp.delegation-token-auth-filter.enabled=false\nyarn.resourcemanager.webapp.ui-actions.enabled=true\nyarn.timeline-service.http-authentication.simple.anonymous.allowed=true\nyarn.timeline-service.http-authentication.type=simple\nyarn.webapp.api-service.enable=true\nyarn.webapp.ui2.enable=true\nranger.add-yarn-authorization=false\n\n\nSome of these seem way off base to me, like the hbase stuff, since I don't think that has anything to do with what I'm seeing. However, some users, in other situations, had it work for them so I wanted to try it.\n\nDigging through the documentation it seems like you need to be authenticated before you can call the API. However, that same language was in the documentation for 2.6.5, which is the version of YARN I was running before where this worked.\n\nHopefully someone can point me to documentation that more clearly outlines what I can do to resolve the issue.\n\nThanks in advance."

However, I can't figure out how to do that.\n\nWhat I want is to have int[] pixelData and byte[] pixelDataBytes both point to the memory. Just be two different \"views\" of the same bits in memory if you understand what I mean. Then I can update the individual bytes as they come in without shifting them, while still maintaining the int[] representation I need for other parts of the code. It seems like this should be possible, but I haven't figured out how to do it yet."

Important info: I have 3 tables - enrollment, cancel, and claims. There are files located on a server that populate these tables every day. These files are NOT deltas (i.e. each new file placed on server every day contains data from all previous files) and because of this, I am able to simply drop all tables, create tables, and then populate tables from files each day. My question is regarding my claims table - since tables will be dropped and created each night, I need a way to keep track of all the different status changes. \n\nI'm struggling to figure out the best way to go about this.\n\nI was thinking of creating a claims_history table that is NOT dropped each night. Essentially I'd want my claims_history table to be populated each time an initial new record is added to the claims table. Then I'd want to scan the claims table and add a row to the claims_history table if and only if there was a change in the status column (i.e. claims.status != claims_history.status).\n\nDay 1: \n\nselect * from claims \n\nid | name | status\n 1 | jane doe | received\n\nselect * from claims_history \n\nid | name | status | timestamp\n 1 | jane doe | received | datetime\n\n\nDay 2: \n\nselect * from claims \n\nid | name | status\n 1 | jane doe | processed\n\nselect * from claims_history \n\nid | name | status | timestamp\n 1 | jane doe | received | datetime\n 1 | jane doe | processed | datetime\n\n\nIs there a SQL script that can do this? I'd also like to automatically have the timestamp field populate in claims_history table each time a new row is added (status change).

Is there any method/function to access a sheet similar to the path system in Windows?

"How do I avoid deadloop if a user enters a char into a scanf looking for an interger?",
"I've been searching the web for a while now, without finding a satisfying answer. Now I'll try my luck here. So here it goes:\n\nIn my program I want a user to enter a number, via the terminal, for this I use scanf(). Rather simple, I know... and I've got that working. But I also want to make it \"idiot-proof\". Thus I'm trying to make sure that if the user enteres a character and not an interger, the program won't deadloop.\nAs it is now, if a character is entered the program will deadloop.\n\nMy code is:\n\nlong fs = 0;\nprintf(\"Enter the samplefrequency(in Hz) and press 'ENTER': \");\nwhile(fs<=0)\n{\n scanf(\" %li\", &fs);\n\n if(fs <= 0)\n {\n printf(\"\\nThe samplefrequency must be above 0 Hz. Please enter again: \");\n }\n}\n\n\nThis will keep printing the line in the if-statement.\nHow do I avoid this?"

"Update WSS 3.0 Event Handler",
"I am implementing an event handler in a WSS 3.0 environment. I've created a VS project with a new class that inherits from SPEventItemReceiver. I built my project and manually deployed this assembly to the GAC via copy/paste. I use a simple console program to add the event handlers to my SharePoint list. The first iteration of my event handler code worked as expected.\n\nFor my next step, I updated the code in my event handler to change the functionality. I've tried removing the assembly from the GAC and re-adding it. That didn't help. I've unregistered and re-registered my event handlers for the list and that did no good either. Even though the code is different and I've re-deployed the assembly - I'm still getting the old (original) functionality.\n\nAn example of this change: Originally I was assigning a text field with a hard coded value. In the updated code that assignment still exists but I've changed the hard coded value I'm assigning. Now, when the event handler fires - it's still assigning the original value.\n\nCan anyone help me understand why my updated code isn't working and how I would go about deploying my updated event handler code?\n\nThanks!!!"

"Laravel passport: increase \"laravel_token\" cookie expire time",
"I have Laravel Passport implemented in my project and it is everything working well except the cookie expiration time where the tokens are being stored (that is just 1 hour).\n\nMy project consists in a backend Laravel 5.8 api (with Laravel Passport) that serves a front SPA app (Vue).\n\nUsers from my app can login successfully using a page with a Vue component that makes a POST request with the user credentials and, if the login is successfully done, users are redirected to a new URL (app home) - this redirection is a GET request that creates the \"laravel_token\" cookie - created by the CreateFreshApiToken middleware.\n\nFrom now on, users can go everywhere inside the app and all data needed from the app components' is obtained through ajax calls (Laravel will note the presence of the cookie \"laravel_token\" in these ajax calls and will identify the logged in user using the JWT present in that cookie).\n\nMy problem is:\n\nThe \"laravel_token\" cookie that was created when user logged in was created with a lifetime of just 1 hour. Because this is a SPA, this cookie never gets updated (exchanged by a new one, with a new hour lifetime)... so, after 1 hour, when a new ajax request needs to be done to the backend Laravel server, it will receive an Unauthenticated response - that makes sense because \"laravel_token\" cookie is outdated.\n\nHow do you deal with this problem?\n\nI know that i can refresh this cookie by perfoming a full refresh/reload of the page before this cookie expire but this is not a good solution in terms of user experience.\n\nI can't make an ajax call to refresh this cookie because this is a SPA and i don't have the client_id and it's secret from client side... and also because not only this cookie is httponly but also it is encrypted by Laravel - so, i can't exchange it by a new one using JS.\n\nIs the only solution increase the lifetime of this cookie (from 1 hour to.... 1 year, for example)? Do you see any problem with this? And where can i set this cookie expiration time? Does i need to extend the ApiTokenCookieFactory class?\n\nI would like user to be logged in until he deliberately performs a logout request or the access_token expires (that, in my case that i am using Laravel Passport defaults, is a long-lived token of 1 year).\n\nI would appreciate if someone could help me with this problem.\n\nIf you see something that i am not doing the correct way, i also would appreciate your comments with suggestions.\n\nThank you very much!"

"Extended menu on a different domain",

Therefore, they need some additional content, specific to the other branch's geographic area, in the menu, as well as a slightly different theme on the front page.\n\nSo, to make it clearer: domain1.com and domain2.com both point to the very same installation of Drupal on one server, but not 100% of the content is shared between them.\n\nI don't usually work with Drupal, so I'm not sure how to tackle this. How would you approach the issue? Is there a way to add or remove a single menu item depending on the domain that is being used? Is there a way to use a different view in the same scenario?\n\nBoth contrib modules and programmatic solutions will be appreciated."

What type of relationship can I have between the Privilege and the User table?\n\n\nI'm new to Entity Framework so I need some guides. Please can anyone be very kind to provide some help. Thank you"

"Adb starts with an unattached emulator",
"When I start Eclipse, I always see emulator-5554 in the Devices View. If I start an application (in automatic target selection mode), it starts on this emulator, but the emulator doesn't have a window. I have to stop the system.process of the emulator every time after Eclipse startup.\n\nI was playing around with adb from the command line, so probably I caused the issue, but I can't figure out, how. \nWhen I restart adb with the commands 'adb kill-server' and 'adb start-server', emulator-5554 starts again, so adb starts it automatically.\n\nI read this document, but I couldn't find any information on emulator automatic startup. Neither a google search on \"adb autostart emulator\" helped.\n\nHow can I keep adb from running this emulator at startup?"
