.net - TaskFactory.StartNew versus ThreadPool.QueueUserWorkItem -

-

Apparently the method is substituted as the replacement for .NET 4.0 (). My question is simple: does anyone know why?

What is the TaskFactory.StartNew better performance? Does it use less memory? Or is it mainly for additional functionality provided by the task class? In the latter case, StartNew might display worse from

That StartNew will actually use memory in comparison to more QueueUserWorkItem , because it has a task with each call object and I hope this results in more memory allocation.

In any case, I am interested in knowing which one is more suitable for high performance scenario.

The display is one ... depending on if you are doing multiple parallel functions, then the NAT4 function Will perform better, and give you more precise control (more strong cancellation, ability to wait simultaneously on many tasks, parent / child ability to make work relation, longrunning ability etc .. etc .. etc)

In addition, do your own work Ishtkrta means the ability to specify that you can customize for your needs. The built-in task scheduler has more multi-core information than the old Threadpool.

To use more memory, each thread keeps a minimum of 1 MB of memory, the small amount used to store the work object is unimportant. I really think that your last concern is .

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
