"Get status from trainer in ML Engine job (Google Cloud Platform)",
"we have the following architecture to connect with GCP (Google Cloud Platform):\n\n\nModule A: Launches ML Engine jobs remotely (ex: from AWS, our local machine...)\nModule B: GCP (ML Engine). Accepts external requests and runs a specific trainer that we configured.\nModule C: Trainer. It is ran by ML Engine. It runs a learn process and creates a model under /export/Servo/<timestamp>.\n\n\nSo, from what we have seen in the GCP documentation, to override this path we would need to re-implement estimator.export_savedmodel which we totally want to avoid.\n\nThe other solution that we thought about was to send the output folder from the trainer to the ML Engine job, so that when our Module A asks for the status of that ML Engine Job, it gets the output folder.\n\nIs there a way to do this? Is there any easier way?"

"Garbage Collection and Callbacks",
"If I have object A, which calls DAO object B to perform some database update - Once B's function completes it calls a call back function in A (A.finishProcess()) does this create memory issues? I mean does B then remain in memory until A completes? or is B still removed with GC?\n\nI ask this as I'm considering using call backs instead of returning a \"result\" object or code from B.\n\nIn short, is it better design (and memory usage) wise to \"return\" an object of results rather than using a callback to a calling object?\n\nPS: Please ignore specific's ie, it doesn't mention AsycnTask, its a contrived situation to get my question across :)\n\nCheers for any help"

"Iterate over arguments in a bash script and make use of their numbers",

It's important because the output files get used separately later in the script. All of the provided answers so far seem correct but I don't know how to use them to make use of the argument's \"number\"."

"I'm trying to deploy a Django app with gunicorn on Heroku and I've run into a few hitches.\n\nWhen I began my project my Django version was 1.3 and didn't contain the standard wsgi.py module, so I added the standard wsgi module as top/wsgi.py (top being my project name, turk being my app name, topturk being the containing directory - preserved so error logs make sense below).\n\nNow when I run\n\ngunicorn top.wsgi:application -b 0.0.0.0:$PORT\n\n\nThe server successfully starts up,\n\n19:00:42 web.1 | started with pid 7869\n19:00:42 web.1 | 2012-07-25 19:00:42 [7869] [INFO] Starting gunicorn 0.14.5\n19:00:42 web.1 | 2012-07-25 19:00:42 [7869] [INFO] Listening at: http://0.0.0.0:5000 (7869)\n19:00:42 web.1 | 2012-07-25 19:00:42 [7869] [INFO] Using worker: sync\n19:00:42 web.1 | 2012-07-25 19:00:42 [7870] [INFO] Booting worker with pid: 7870\n\n\nbut then when I navigate to 0.0.0.0:5000 I get returned an Internal Server Error:\n\n19:00:45 web.1 | 2012-07-25 17:00:45 [7870] [ERROR] Error handling request\n19:00:45 web.1 | Traceback (most recent call last):\n19:00:45 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/gunicorn/workers/sync.py\", line 102, in handle_request\n19:00:45 web.1 | respiter = self.wsgi(environ, resp.start_response)\n19:00:45 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/django/core/handlers/wsgi.py\", line 219, in __call__\n19:00:45 web.1 | self.load_middleware()\n19:00:45 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/django/core/handlers/base.py\", line 47, in load_middleware\n19:00:45 web.1 | raise exceptions.ImproperlyConfigured('Error importing middleware %s: \"%s\"' % (mw_module, e))\n19:00:45 web.1 | ImproperlyConfigured: Error importing middleware turk.middleware.subdomain: \"No module named turk.middleware.subdomain\"\n19:00:47 web.1 | 2012-07-25 17:00:47 [7870] [ERROR] Error handling request\n19:00:47 web.1 | Traceback (most recent call last):\n19:00:47 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/gunicorn/workers/sync.py\", line 102, in handle_request\n19:00:47 web.1 | respiter = self.wsgi(environ, resp.start_response)\n19:00:47 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/django/core/handlers/wsgi.py\", line 219, in __call__\n19:00:47 web.1 | self.load_middleware()\n19:00:47 web.1 | File \"/Users/intenex/Dropbox/code/django/topturk/venv/lib/python2.7/site-packages/django/core/handlers/base.py\", line 47, in load_middleware\n19:00:47 web.1 | raise exceptions.ImproperlyConfigured('Error importing middleware %s: \"%s\"' % (mw_module, e))\n19:00:47 web.1 | ImproperlyConfigured: Error importing middleware turk.middleware.subdomain: \"No module named turk.middleware.subdomain\"\n\n\nI'm assuming this is a python path error, where the server doesn't know how to import from my app directory\n\nThe relevant import code is here in settings:\n\nMIDDLEWARE_CLASSES = (\n 'turk.middleware.subdomain.SubdomainMiddleware',\n 'turk.middleware.removewww.RemoveWWWMiddleware',\n)\n\n\nI attempted to fix this problem by inserting my app directory into sys.path like so at the top of my settings.py file like so:\n\nPROJECT_ROOT = os.path.dirname(os.path.realpath(__file__))\nsys.path.insert(1, PROJECT_ROOT+'/turk/')\n\n\nWhich I've verified adds the app directory to the path, but still no dice. Any ideas? Also\n\nsys.path.insert(1, PROJECT_ROOT+'/turk/')\n\n\nseems hackish and adds at least two copies of the directory to the path, what's the correct way to append to PYTHON_PATH in Django?

"Does Rust implicitly create map entries when indexing, like C++?",
"In C++ the indexing operator is defined for std::map and std::unordered_map so that if your reference to the container is non-const just the act of indexing without assigning is enough to have implicitly created a value inside the container. This sometimes creates subtle bugs, where you expect to be referencing a value inside a container but instead actually create one, e.g. config[\"stting\"] instead of config[\"setting\"].\n\nI know Python addresses this by having __setitem__ and __getitem__ be separate methods but this requires cooperation with the parser.\n\nDoes Rust do anything to address this frequent source of bugs?"

"java library for high-performance graph/network data structure",
"Well, is there a high-performance graph library for working with primitivies, without those generics/autoboxing overheads? For double lists you may use trove, for linear algebra you may use netlib-java (examples for you to better understand the point of my interest in this question).\n\nAs for Graphs/Networks: all the libs I've found use generics and should be not that performant. I may as well do some tests for that, but I believe that heap-managed network link weights would be inferior to double[] with some bit offsets to get the index for i and j. The usage scenario: there're hundreds of such networks (most of them sparse) of size 4k*4k, there's some genetic optimization running over that set of networks, which do some flow/min route estimations for each specimen.\n\nSo, there're: JGraphT, JUNG, ANNAS, JDSL (the links lead to the APIs/code samples which expose the miserable Java Generics/Object wrappers in all of them). Are there any Trove-ish alternatives? I'd already created some simplistic implementation, but just decided to look around to avoid inventing the proper bicycle...\n\nAny opinions, suggestions?\n\nThanks,\nAnton\n\nPS: Please don't start on performance of generics-laden Java code, at least without linking to some decent benchmark, ok? ;)"

"How to dynamically update the attributes of a model in Spring MVC?",
"so I'm pretty new to Spring and used the Spring Initializr to create a new project. I do not have any configuration .XMLs or similiar configuration files. I followed this tutorial to get things going.\n\nMy controller class basically looks like the following:\n\n@Controller\n@Configuration\n@EnableScheduling\npublic class IndexController {\n\n@GetMapping(\"/\")\npublic String index(Model m) {\n m.addAttribute(\"Title\", \"New Website\");\n m.addAttribute(\"MenuOne\", InformationProvider.getMenuOneLink());\n m.addAttribute(\"MenuTwo\", InformationProvider.getMenuTwoLink());\n m.addAttribute(\"StaffNumber\", InformationProvider.getNumberOfStaff());\n m.addAttribute(\"Birthdays\", InformationProvider.getBirthdaysOfToday());\n\n return \"dashboard\";\n}\n\n\n}\n\nThis works fine and everything is doing what it is supposed to be. Unfortunately the attributes which are getting their data by the InformationProvider class need to be updated at run time. The InformationProvider is approaching different APIs on the web and my idea either was to pull data from these APIs every 10 hours for example or to pull the data again on a site refresh. \n\nFrom my understanding my method is supposed to be called each time someone would enter the URL localhost:8080/. My first idea basically was to refresh the site after 10 hours. The method is called when the site is refreshed and it is returning \"dashboard\" each time but the values are not updated. To update my attributes I have to restart my application. I was looking at the @scheduled annotation but this does not really help me since it is only working for methods which have void as return time and do not have object parameters. So scheduling my method index doesn't work and is probably the wrong way to go anyway.\n\nI was googling a lot regarding this topic but I couldn't really find a solution for this specific problem where you only have a model as parameter in your controller method and want to update it afterwards. \n\nWhat is the best approach for this problematic? I was checking the JavaDoc of the model class but it does not contain a remove or update method. Do I need to approach the HashMap behind the model directly and overwrite an attribute by an existing key to update it?\n\nEdit:\n\nTo be more specific about the InformationProvider class, it is basically returning a String received by a cURL method called from Java. Nothing more.\n\nThanks in advance"

"Why is CUDA pinned memory so fast?",
"I observe substantial speedups in data transfer when I use pinned memory for CUDA data transfers. On linux, the underlying system call for achieving this is mlock. From the man page of mlock, it states that locking the page prevents it from being swapped out:\n\n\n mlock() locks pages in the address range starting at addr and continuing for len bytes. All pages that contain a part of the specified address range are guaranteed to be resident in RAM when the call returns successfully; \n\n\nIn my tests, I had a fews gigs of free memory on my system so there was never any risk that the memory pages could've been swapped out yet I still observed the speedup. Can anyone explain what's really going on here?, any insight or info is much appreciated."

"Best practice for user login after hashing and storing password in mysql with node bcrypt",
"I just created a handler that stores a username and password in mysql. The handler function performs the standard bcrypt password hash:\n\nbcrypt.hash(myPlaintextPassword, saltRounds, function(err, hash) {\n // Store hash in your password DB. \n});\n\n\nBcrypt also offers the standard code to compare the plaintext with the hash like so:\n\nbcrypt.compare(myPlaintextPassword, hash, function(err, res) {\n // res == true \n});\n\n\nOn an abstract level if I were to do the above compare function I would need to do the following:\n\n\nGet user input username and plain text password\nSend query to database SELECT * FROM users WHERE username = 'SomeName'\nGet back some username and hashed password\nCompare hashed password and authenticate user\n\n\nThe problem with that is that any user specific data cannot be retrieved before authentication so I will need to chain an additional query in order to retrieve any extra user sensitive data and this process would seem janky. And it seems unsafe because the client then has the hashed password at this point when there should be no need to bring back the password.\n\nI would like to:\n\n\nGet user input username and plain text password\nSend query to database \n\nSELECT * FROM users \nWHERE username = 'SomeName' \nAND password = COMPARISON_FUNCTION_THAT_WORKS_WITH_BCRYPT('plaintext')\n\nGet back some username and any user specific data\nand I am done\n\n\nAm I completely missing the boat here, because if I am then what exactly are the 360k downloaders of this software doing for password encryption / user login process?"

"Why doesn't \"display: block\" & \"width: auto\" stretch a button to fill the container?",
"When I set display: block; and width: auto; on a button, I'd expect the button to stretch to fill the container as other block elements do.

(I'm perfectly able to stretch my buttons any way I need.)

"Terraform setup tips: TLS communication across VPCs",
"I'm working for a client that has a simple enough problem:\n\nThey have EC2s in two different Regions/VPCs that are hosting microservices. Up to this point all EC2s only needed to communicate with EC2 instances that were in the same subnet, but now we need to provision our infrastructure so that specific ec2s in VPC A's public subnet can call specific ec2s in VPC B's public subnet (and vice versa). Communications would be calling restful APIs over over HTTPS/TLS 2.0\n\nThis is nothing revolutionary but IT moves slowly and I want to create a Terraform proof of concept that:\n\n\nCreates two VPCs\nCreates a public subnet in each\nCreates an EC2 in each\nInstalls httpd in the EC2 along with a Cert to use SSL/TLS\nCreates the proper security groups so that only IPs associated with the specific instance can call the relevant service\n\n\nThere is no containerization at this client, just individual EC2s for each app with 1 or 2 backups to distribute the load. I'm working with terraform so I can submit different ideas to them for consideration, such as using VPC Peering, Elastic IPs, NAT Gateways, etc.\n\nI can see how to use Terraform to make these infrastructural changes, but I'm not sure how to create EC2s that install a server that can use a temp cert to demonstrate HTTPS traffic.

"Modular comparison of characters",
"This seems like a very simple question, but there's surprisingly little written about it on the Internet, and I'm having a hard time implementing it correctly on my own. What is the best way to implement a modular comparison function on ASCII characters in Java, such that the comparison \"wraps around\" the end of the alphabet? I want to use it for a \"between\" function that can partition the entire alphabet at arbitrary locations, and correctly return \"true\" when asked if 'y' is between 'x' and 'b'.\n\nI've already found all the questions and answers that talk about modular arithmetic on characters, so I know how to do modular addition (character shifting) with code like this:\n\nchar shifted = (((original - 'a') + 1) % 26) + 'a';\n\n\nHowever, this is based on Java's built in modular arithmetic functions, which have no equivalent for comparison. Even if I was using plain ints, I have no way of asking Java if a < b < c mod 26 (which should return true if a = 24, b = 25, and c = 1).\n\nSo the general question is, what's the best way to implement modular comparison operations in Java? If that's too hard a problem, is there at least a way to get such comparisons to work for the ASCII alphabet?"

This works fine for the HTML and CSS that is in the JSPX page, however there a javascript file is sourced, and substituting the <spring:message> tag for the string in there just means that it gets printed out verbatim. \n\nMy JSPX sources the javascript like so:\n\n<spring:theme code=\"jsFile\" var=\"js\" />\n<script type=\"text/javascript\" src=\"${js}\" />\n\n\nThe JS where I'm looking the replace the string is below:\n\nbuildList('settings', [{\n name: '<spring:message code=\"proj.settings.toggle\" javaScriptEscape=\"true\" />',\n id:\"setting1\",\n description: '<spring:message code=\"proj.settings.toggle.description\" javaScriptEscape=\"true\" />',\n installed: true\n}]);\n\n\nAnd finally the message.properties is something like:\n\nproj.settings.toggle=Click here to toggle\nproj.settings.toggle.description=This toggles between on and off\n\n\nSo what I'm wondering is, should this work? It seems to me like it should, from what I've gathered on various forums, but I can't figure out where I'm going wrong. Is there a better way to go about this?\n\nI should also note that these files are outside the WEB-INF folder, but by placing the ReloadableResourceBundleMessageSource in the root applicationContext.xml the spring tags are picked up.\n\nThanks for any help!"

The problem is that I don't know if append(' ') is a good idea and the second problem is that after injection of the spans to the second paragraph width of it is too large (it should be 100px with text overlaping to next line juz like in first paragraph\n\nhere is my attempt\n\n <body>\n<script type=\"text/javascript\">\n $(function(){\n var obj = $('.p1')\n var text = obj.html().split(' '), len = text.length, result = [];\n for( var i = 0; i < len; i++ ) {\n result[i] = '<span id=\"'+i+'\">' + text[i] + '</span>';\n }\n obj.html(result.join(' '));\n\n var words = $('.p1').find('span');\n for(var i = 0; i < 5; i++){\n $('.p2').append($(words[i]).clone());\n $('.p2').append('&nbsp;');\n }\n });\n</script>\n\n<div class=\"test\" style=\"width:100px\">\n<p class=\"p1\">\ntest1 test2 test3 test4 test5 test6 test7 test8\n</p>\n</div>\n<div class=\"test\" style=\"width:100px\">\n<p class=\"p2\">\n</p>\n</div>\n</body>"

"In a multithreaded process on a system with multiple (physical) CPUs, how is thread scheduling handled?",
"Kind of a broad question, but I'm curious about the details of thread scheduling in a single process application on a machine with multiple physical CPUs.\n\nEDIT - wanted to clarify that below im talking about phyiscal CPUs. I've got a pretty good handle on how a process/threads work with a multicore CPU, but I'm talking multiple physical CPU dyes on the motherboard (like 2 4-core Xeons).\n\nANSWER - thanks to the responses from brokenfoot and nosid, I think I've got it:\n - Linux scheduler has different NUMA policies that affect thread scheduling in regards to their memory mutation/access patterns in regards to core/dye.\n - Cache coherency across dyes is possible, but slower as expected.\n - Best course of action- control mutability of shared memory (try to be immutable)\n - Use an internal (in-process) task scheduler that respects locality of threads\n - Use a NUMA policy that works with your in-process task scheduler\n\nAssumptions:\n\n\nCache coherency is the magic that allows multiple cores to operate on shared memory. (confirmed)\nAs far as I know, cache coherency is possible over multiple CPUs, but at reduced performance (Linux 3+, system has multiple modern multi-core Xeons CPUs). (confirmed)\n\n\nSo the situation: \n\n\nI have a multi-threaded single process service that does... stuff, in parallel. It can effectively utilize multiple cores and divides work up in a way that generally avoids cpu-core cache misses and coherency abuse. Executor has relative thread-affinity for tasks. \nThe service threads can utilize shared data (mostly immutable) in the process.\nThe service architecture is done in a way that running multiple processes on the same box is possible, but is advantageous to have only 1 process per box (shared cache, resources, etc). \n\n\nThe questions:\n\n\nIs cache coherency possible between multiple CPUs? Is it practical? (It is, at reduced performance)\nHow will linux schedule the threads between CPUs? (If possible)\nIs there some way to pin a process to a single CPU? (confirmed)\nAnd ultimately... do I do one process per CPU and pin? Or 1 per box (which would be cool, if i dont screw myself with slow cross-CPU cache misses) (starting to sound like 1 process is good, as long as my parallel tasks have affinity to a certain thread and mostly immutable data)"

"twilio missing attributes c#",

"I am very much interested in ILNUmerics and would like to try the free version, but I am having troubles.\n\nI have started with a console application and was trying to run the 'hello ilnumerics'console application but I noticed that VS fails to find MKL libraries.\n\nI am using VS2012 under Windwos 8 (through Bootcamp on a MacBook Pro mid 2010; should it be relevant); I have installed the NuGet Packages extension from the Project solution. Then right-click on references in the solution explorer, 'Manage Nu Get Packages', fron online/search found ilnumerics in various versions. I chose 'ILNumerics' and install. I got 'ILNumerics' and 'ILNumerics.Native' added to my project. Then I can see ILNumerics under 'References' in Solution Explorer and also get two new folders /bin32/ and /bin64/ they both contain two DLLs named: libiomp5md.dll and mkl_custom.dll. I have checked their \n'Copy to Ouput Directory' property and they are all set to 'Copy if newer'.\n\nApparently mkl_custom is not found. I write the following code, taken from the quickstart guide:\n\nusing System;\nusing System.Collections.Generic;\nusing System.Linq;\nusing System.Text;\nusing System.Threading.Tasks;\nusing ILNumerics;\n\nnamespace ConsoleApplication3\n{\n\n class Program : ILMath\n{\n static void Main(string[] args)\n {\n\n ILArray<double> A = array<double>\n (new double[] { 1,1,1,1,1,2,3,4,1,3,6,10,1,4,10,20} ,4, 4);\n ILArray<double> B = counter(4, 2);\n\n ILArray<double> Result = linsolve(A, B);\n Console.Out.WriteLine(\"A: \" + Environment.NewLine +\n A.ToString());\n\n Console.Out.WriteLine(\"B: \" + Environment.NewLine + B.ToString());\n\n Console.ReadKey();\n }\n }\n}\n\n\nand I get this exception:\nAn unhandled exception of type 'System.DllNotFoundException' occurred in ILNumerics.dll\n\nAdditional information: Unable to load DLL 'mkl_custom': The specified module could not be found. (Exception from HRESULT: 0x8007007E)\n\nIf I do not invoke linsolve the ToString method of ILArray does work: if I comment // ILArray Result = linsolve(A, B);\n\nI get the two matrices printed on the screen.\n\nI have also tried to compute the determinant of a matrix and got the same exception: apparently any time I call mkl_custom VS is not capable to find it. \n\nAny help/hint, please?\n\nAlso, is it necessary to install ILNumerics through NuGet on any project added to the solution?

My first thought is that this code was meant to be developed under a different environment/architecture.\n\nThe documentation states “This program was designed to run on the HARRIS computer system. It also can be run on VAX system if the single precision variables are changed into double precision variables both in the main code and the subroutine package.”\n\nI have tried changing the single precision variables to double precision variables, but I may have done that wrong. If this is the correct thing to do any insight would be great.\n\nI have also tried compiling the coding with -std=legacy and -m32.
