i'm little new sql server, , working in java application connecting it. found these 2 well-known jdbc drivers, microsoft 1 , jtds one. i'm trying use xa datasource. according microsoft documentation, here says have configure server, before using xa datasource. according doc, asks enable xa in server. but don't see such server-side modification required jtds. (i couldn't find doc saying so, here ) so, question how jtds manage enable xa in server, while microsoft 1 needs me enabling task? or missing here? found answer after digging in jtds driver distribution. has readme.xa file saying all. copying content below. xa support in jtds ================== version of jtds includes xadatasource class allows driver used j2ee servers support xa jdbc connections. class name net.sourceforge.jtds.jdbcx.jtdsdatasource. default driver emulate distributed transactions fooling j2ee environment believing 2 phase commit supported. emulation has serious drawback...

client.query("select * rooms token = ?", [data.token], function(err, results, fields) { callback(results); console.log(results); }); this query returns result array. how can necessary fields? looking @ comment, if json object -: [ { "bump":"1376149484", "user":"alex", "token":"11569", "active":0 } ] you can iterate through object -: for (var in results) { console.log('bump = ' + results[i].bump); console.log('user = ' + results[i].user); console.log('token = ' + results[i].token); console.log('active = ' + results[i].active); }

i learning vb.net 2008. have come across situation i want build recursive program factorial of number or fibonacci series 1st 50 terms, using tools windows in vb.net 2008. eg., type number in text box, click on button , output of factorial of number displayed on label. inner code should implemented in recursive way , not using simple loops only. i not finding proper way solve this. please, me out. thanks lot. you can use recursive function calls itself. private sub button1_click(sender object, e eventargs) handles button1.click label1.text = factorial(clng(textbox1.text)) end sub function factorial(byval number long) long if number <= 1 return (1) else return number * factorial(number - 1) end if end function

at present have server(service) client(activity) working project operated in same process. trying move server new process adding android:process=":seperateservice" in manifest. however, after successful bind service, in function public void onserviceconnected(componentname arg0, ibinder arg1) the arg1 parameter received null. appears when service made have separates processes. what missing? solved using: aidl = binder.stub.asinterface(arg1); instead of: aidl = (binder) arg1; but not sure of why not problem when both client , server in same process.

is there option such log='y' when plotting frequency table. code following: df = read.table(myfile, header=f, sep=',') freq = table(df[[1]]) # make frequency table first column plot(freq, log='y') however cannot display logarithm. error message : warning messages: 1: in plot.window(...) : nonfinite axis limits [gscale(-inf,7.0814,2, .); log=1] 2: in axis(...) : "log" not graphical parameter thanks! maybe want this: plot(as.numeric(names(freq)),as.numeric(freq),log='y',xlab='',ylab='freq')

i've got small problem. i've written module parse configuration file (wvdial's wvdial.conf) using regex. file contains strings "init1 = at" , i've used following regex: match = re.match(r'(.*)=(.*)', line) everything worked until following line: #init3 = at+cpin="0000" which got parsed like: '#init3 = at+cpin':'0000' it seems regex engine goes right left parsing string. there way reverse re.search direction? you need mark first * quantifier non-greedy appending ? : match = re.match(r'(.*?)=(.*)', line) demo: >>> line = '#init3 = at+cpin="0000"' >>> re.match(r'(.*?)=(.*)', line).group() '#init3 = at+cpin="0000"' by making quantifier non-greedy, regular expression engine match minimum satisfy pattern, rather maximum.

is there annotation or other way tell jackson serialize string variables's value without quotation marks. serializer should serialize 1 field's value without quotation marks. i looking return of similar to: {"name": "namevalue", "click" : function (e){console.log("message");}} instead of {"name": "namevalue", "click" : "function (e){console.log("message");}"} the above how external java script library requires data, if there not way have manual alter string after object mapper has converted json. as others have pointed out, double-quotes not optional in json, mandatory. having said that, can use annotation jsonrawvalue want. public class pojo { public string name; @jsonrawvalue public string click; }

while reading tips in c . have seen tip here http://www.cprogramming.com/tips/tip/multiply-rather-than-divide iam not sure. told both multiply , divide slower , time consuming , requires many cycles. and have seen people use i << 2 instead of i x 4 since shifting faster. so me this.is tip using x0.5 or /2 ? or modern compilers optimize in better way? want know views of guys stackoverflow. also post links useful tips n traps in c. appreciated. it's true (if not most) processors can multiply faster performing division. but, it's myth of ++i being faster i++ in loop. yes, once was, nowadays, compilers smart enough optimize things you, should not care anymore. and bit-shifting, once faster shift << 2 multiply 4, these days over, processors can multiply in 1 clock cycle, shift operation. great example of calculation of pixel address in vga 320x240 mode. did this: address = x + (y << 8) + (y << 6) to multiply y 320. on modern ...

would event.timestamp , date.gettime() return same values if taken @ exact same time? for instance, use gettime() in order calculate how time passed since event occurred, or might happen 2 use different epoch / references? no, they're on same reference, utc, time zone of date internal storages. you can use date.now() .
