i'm trying create class in java pool objects. class starts creating minimum amount of objects required, when requests start kick in, every thread checks if there object available, if can create because maximum has not been reached yet, or if otherwise has wait one. the idea threads needs synchronize get/create engine, can process in parallel ( processwithengine method). processing take couple of minutes, , apparently it's working want. the problem is, sometimes when .notify() has been called , thread released .wait() , queue has 0 items, , should impossible because before .notify() , item added. what problem? the code this: queue _queue = new queue(); int _poolmax = 4; int _poolmin = 1; int _poolcurrent =0; public void process(object[] parameters) throws exception { engine engine = null; synchronized(_queue) { if(_queue.isempty() && _poolcurrent >= _poolmax) { _queue.wait(); // here : _queue....

my example code in python i'm asking general principle. if have set of data in time-value pairs, should store these 2d array or list of tuples? instance, if have data: v=[1,4,4,4,23,4] t=[1,2,3,4,5,6] is better store this: data=[v,t] or list of tuples: data=[(1,1),(4,2)(4,3)...] is there "standard" way of doing this? the aggregate array container best choice. assuming time points not regularly spaced (and therefore need keep track of rather use indexing), allows take slices of entire data set like: import numpy np v=[1,4,4,4,23,4] t=[1,2,3,4,5,6] data = np.array([v,t]) then slice subset of data easily: data[:,2:4] #array([[4, 4],[3, 4]]) ii = [1,2,5] # fancy indexing data[:,ii] # array([[4, 4, 4], # [2, 3, 6]])

how convert colors in rgb format hex format , vice versa? for example, convert '#0080c0' (0, 128, 192) . the following rgb hex conversion , add required 0 padding: function componenttohex(c) { var hex = c.tostring(16); return hex.length == 1 ? "0" + hex : hex; } function rgbtohex(r, g, b) { return "#" + componenttohex(r) + componenttohex(g) + componenttohex(b); } alert( rgbtohex(0, 51, 255) ); // #0033ff converting other way: function hextorgb(hex) { var result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex); return result ? { r: parseint(result[1], 16), g: parseint(result[2], 16), b: parseint(result[3], 16) } : null; } alert( hextorgb("#0033ff").g ); // "51"; finally, alternative version of rgbtohex() , discussed in @casablanca's answer , suggested in comments @cwolves: function rgbtohex(r, g, b) { return "#" + ((1 << 24) + (r ...

does know if it's more memory-efficient use nsdata.fromfile or fromstream vs filling nsdata.fromarray? specific case i'm sending large file via email (mfmailcomposeviewcontroller.addattachmentdata). right i'm filling nsdata bytes want send, hoping if use nsdata.fromfile or fromstream, wouldn't ever keep file data in memory @ once. i think out of luck here. if pass data on addattachmentdata() , mail composer copy bytes , hold them in memory (you should see instruments). best can dispose() nsdata passed on release memory fast possible.

is there non-deprectated option in rails 3 can pass data structure in execute query, rather use method chaining approach ? consider hash representing set of critieria limiting set of records (say, documents).. { :conditions => { :account_id => 2 }, :limit => 5, # page size :offset => 5, # (page-1) * page_size :sort => 'id desc' } this may come url such as: /documents.js?page_size=5&page=2&sidx=id&sord=desc&filter[account_id]=2 and want avoid issues of order-importance in translation of hash sequential series of calls of methods: # 'right', or better ? document.offset(5).where(:account_id => 2).limit(5) document.where(:account_id => 2).limit(5).offset(5) i'm concerned programmatic transformation of set of query criteria inferred http parameters or json objects may more complicated if have walk hash , created chained method calls. you can use classic find method: document.a...

this pretty question posed me recently. suppose have hypothetical (insert favorite data storage tool here) database consists of names, ages , address of people residing on planet. task print out names of people age greater 18 within html table. how go doing that? lets hypothetically population growing @ rate of 1200/per second , database updated accordingly(don't ask how). strategy print names of these people , addresses on html table? storing ages in db tables sounds recipe trouble me - impossible maintain. better off storing birth dates , building index on column/attribute. you have initial dump of table display. calculate date 18 years ago (let's d0 ) , use query person born earlier that. use db triggers receive notifications deaths, can remove them table immediately. since people older (unfortunately?), can use ranged queries new additions (i.e. people become 18 years old since yo last queried table). e.g. if want update display next day, issue query peopl...

i implemented easyapns in app , server , have database 2000+ registered devices. today tried send notifications of these devices , script timed out. checked code (should've done earlier, know) , discovered opens connection for each message . basically thing never work , ip banned, right? how's possible problem not mentioned anywhere in google group ? apparently nobody tried library lot of notifications -- can real? or missing something? i ended rewriting lot of code sends messages apns. instead of looping through each message opening , closing connection every time, fetch n messages (probably limit 100) database every minute , send them in 1 shot. until messages table empty (i used cron job this). had more work because needed multiple application support. i'm not sure easyapns guys thinking when wrote library. honestly, didn't @ -- have been better if had written apns code scratch on own. should need in modifying library, comment post.
