debugging - AbsoluteTime with numeric argument behaves strangely -

-

यह अजीब है: 

  दिनांक लिस्ट @ निरपेक्ष समय [5 9 6523]   
 रिटर्न 
 
  {2078, 7, 2, 2, 42, 9.7849}  
 
 लेकिन 
 
  दिनांकसूची @ AbsoluteTime [596524]  
 
 रिटर्न 
 
  {1 942, 5, 26, 20, 28, 39.5596}  
 
 सवाल: क्या चल रहा है? ध्यान दें कि एक संख्यात्मक तर्क के साथ AbsoluteTime को undocumented है। 
 
 (मुझे लगता है कि मुझे अब पता है कि यह क्या कर रहा है लेकिन यह समझ गया कि यह भविष्य के संदर्भ के लिए एक StackOverflow प्रश्न के रूप में उपयोगी है; और अगर कोई कारण है उस मैजिक 596523 नंबर के लिए।) 
 
 पीएस: मैथमैटिका में यूनिक्स के समय में परिवर्तित होने के लिए इन यूटिलिटी फ़ंक्शन लिखते समय मुझे इसका सामना करना पड़ा: 
 
  (* यूनिक्स समय का प्रयोग ( एक पूर्णांक) के बजाय गणितिका के AbsoluteTime ... *) टीएम [x ___]: = AbsoluteTime [x] (* टीएम AbsoluteTime के लिए एक उपनाम है। *) Uepoch = tm [[1970}, टाइम ज़ोन-> 0]; (* Unixtm टीएम के अनुरूप काम करता है। *) Unixtm [x ___]: = गोल [टीएम [x] -यूपोक] (* टीएम और यूनिक्स के बीच यूनीक्सम कनवर्ट करें) * यूनीक्स्टएम [x_? NumericQ]: = गोल [x- Uepoch] (* एमएमए युग का समय जब संख्यात्मक * दिया गया है) टीएम [टी_? एन्यूमेरिकक्यू]: = टी + यूईपोक (* एजीआर। आईई, वे उलटा हो। *)

यदि आप 596524 और 596523 को घंटों से सेकेंड (3600 तक गुणा) में परिवर्तित करते हैं तो आप देखेंगे कि बड़ी संख्या 2 ^ 31-1 से अधिक है (अधिकतम 32-बिट पूर्णांक मान पूर्णांक), जबकि छोटी संख्या नहीं है।

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...

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])

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...
