i'am trying measure performance of computer vision program tries detect objects in video. have 3 different versions of program have different parameters. i've benchmarked each of versions , got 3 pairs of (false positives percent, false negative percent). now want compare versions each other , wonder if makes sense combine false positives , false negatives single value , use comparation. example, take equation falsepositives/falsenegatives , see smaller. a couple of other possible solutions: -your false-positive rate (fp) , false-negative rate (fn) may depend on threshold. if plot curve y-value (1-fn), , x-value (fp), you'll plotting receiver-operator-characteristic (roc) curve. area under roc curve (auc) 1 popular measure of quality. -auc can weighted if there regions of interest -report equal-error rate. threshold, fp=fn. report value.

how can break on error? i have code: throw new error("some error"); and i'm using recent version of web inspector (webkit) , firebug(mozilla). these tools catch , print error, not break. may don't know how to. please let me know how can these? in webkit need click enable break on error. if click again break on warnings , clicking again disable it. alt text http://a.yfrog.com/img832/3580/screenshot20100723at101.png

i started work adobe flash , code editor lacks few features before being considered ide. do know other solution developing in flash? as3 coding only, don’t care designer , timeline… want work efficiently code. i'm surprised nobody has come yet flashdevelop . in top 2 of code editors. it's free, problem it's windows only. then, if eclipse, there's editor called fdt , 1 have pay for. people it's totally worth money, don't use because don't eclipse and when tried in linux had various glitches here , there.

to make things easier when switching between machines (my workstation @ office , personal laptop) have thought trying external hard drive store working directory on. looking @ firewire 800 drives (most 5400 rpm 8mb cache). wondering if has experience doing visual studio projects , sort of performance hit see. it depends on size of project. throughput low , latency high, you're going hit every way, due latency you'll hit harder if have lot of little files rather few large ones. have considered carrying around git or other distributed repository , updating machine repositories move around? can compile locally , treat drive , roving server. since changes moved across, should faster, , code 'backed up' in more places. if forget drive, breaks, or lost/stolen, can still sit down @ pc , program no code missing if you're @ last pc used, or little code missing (which updated later resync anyway). and it's hop skip , jump away using network move chan...

we're planning set xen virtualization server using ubuntu. i'm looking recommendations regard watch out when buying hardware system. some information our planned usage of system: the server going host 4 or 5 instances of linux/apache/mysql/j2ee stack. each of instances contain mysql database no more 4 gb of data. of these instances being used mirroring setup of our customers servers able reproduce problems they're reporting, these instances idle of time (if they're started @ all). other instances going used testing purposes , we're going restart them quite often, startup time of our jboss-applicationserver (which cpu-bound) gonna important. contstraint amount of memory our instances need, 1.5 gb jboss , 500 mb mysql. to clarify question little bit: can of course math calculate amount of ram , disk space need run 5 instances given constraints stated above. i'm particularly interested in topics important interplay of xen , hardware (if there any) because...

this question has answer here: in sql, what's difference between count(column) , count(*)? 10 answers i have following code: select <column>, count(*) <table> group <column> having count(*) > 1; is there difference results or performance if replace count(*) count('x')? (this question related previous one ) to select count(*) vs count(1) results in dbms returning "columns" pure bunk. may have been case long, long ago self-respecting query optimizer choose fast method count rows in table - there no performance difference between select count(*), count(1), count('this silly conversation') moreover, select(1) vs select(*) not have difference in index usage -- dbms optimize select( n ) select(*) anyway. see ask tom: oracle has been optimizing select(n) select(*) better part of decade, if not longer:...

i'm single developer looking off of visual source safe , move svn. a quick search brings several tools, don't see clear winner , can't afford spend lot of time testing different tools. has done successfully, , can recommend method? i recommend adding code new subversion repository rather importing vss. vss has convoluted version control model doesn't translate many other systems, , starting fresh best way avoid taking clutter you. if need keep history around, make vss repository read-only.

my motto java "just because java has static blocks, doesn't mean should using them." jokes aside, there lot of tricks in java make testing nightmare. 2 of hate anonymous classes , static blocks. have lot of legacy code make use of static blocks , these 1 of annoying points in our push in writing unit tests. our goal able write unit tests classes depend on static initialization minimal code changes. so far suggestion colleagues move body of static block private static method , call staticinit . method can called within static block. unit testing class depends on class mock staticinit jmockit not anything. let's see in example. public class classwithstaticinit { static { system.out.println("static initializer."); } } will changed to public class classwithstaticinit { static { staticinit(); } private static void staticinit() { system.out.println("static initialized."); } } so can following in junit. public cla...

is there easier way step through code start service through windows service control manager , attaching debugger thread? it's kind of cumbersome , i'm wondering if there more straightforward approach. if want debug service, drop in debugger.break() in there. when line reached, drop me vs. don't forget remove line when done. update: alternative #if debug pragmas, can use conditional("debug_service") attribute. [conditional("debug_service")] private static void debugmode() { debugger.break(); } on onstart, call method: public override void onstart() { debugmode(); /* ... rest */ } there, code enabled during debug builds. while @ it, might useful create separate build configuration service debugging.

i have virtual machine in virtual pc 2007. to start desktop, have following command in batch file: "c:\program files\microsoft virtual pc\virtual pc.exe" -pc "my-pc" -launch but leaves dos prompt on host machine until virtual machine shuts down, , exit out of virtual pc console. that's annoying. so changed command use start command, instead: start "c:\program files\microsoft virtual pc\virtual pc.exe" -pc my-pc -launch but chokes on parameters passed virtual pc. start /? indicates parameters indeed go in location. has used start launch program multiple command-line arguments? start has peculiarity involving double quotes around first parameter. if first parameter has double quotes uses optional title new window. i believe want is: start "" "c:\program files\microsoft virtual pc\virtual pc.exe" -pc my-pc -launch in other words, give empty title before name of program fake out.
