@Phrancis sounds like an excellent idea. I'll reload in bed.
 
insert into Mouth values 'Foot';
 
@Phrancis, I make sure that people use a synthetic key rather than a composite key on their name. The appostophe shouldn't be an issue so long as you're not concatenating strings.
The biggest mistake I see is assuming you'll not have two people with the same name.
I also like to make sure there's an "old key" field, so I can keep track of name changes.
Nobody gets updated, they get marked historic and inserted new.
 
Ah, makes sense. Not very economical, space-wise, but handy for audits and such
 
@RubberDuck that's a "type-2" update, used in data warehousing
Space is not a concern in DW
well, shouldn't be
@RubberDuck table has EffectiveFrom/EffectiveTo dates?
 
12:28 AM
Typically, yes. I've found it's easiest to deal with. EffectiveFrom is required, a null in To indicates that it's an active record.
I've seen weird things with statuses and all kinds of crap, but some simple dates work best IMHO
And partitioning the data keeps the run of the mill active user queries pretty quick @Phrancis.
 
OK sounds good. (looks up partitioning)
 
12:48 AM
Working on wrapping up a rap instrumental that would probably appeal to people who are akin to Final Fantasy and other such RPGs (talking about old FF, new stuff is way different)
 
Phrancis Uematsu?
 
Yeah
My music partner used way too much copy & paste... plain simple chords throughout... I've been working on improving it for a couple hours...
 
1:04 AM
3 & 7 had killer soundtracks.
 
I think my favorite is "To Zanarkand" from FFX. I tried to learn it on acoustic guitar a number of years ago
 
It's got a bit of a 7 sound to it... By 3 you mean 6 right? @RubberDuck Super Nintendo was 3 but it was really 6
 
But either made you want to mute it after a solid 8 hours of playing... Damn those games were good.
 
@RubberDuck FF6 yeah ;)
 
No. I mean III. It wasn't released here until it came out on play station.
 
1:05 AM
Oh and "Terra's Theme" is timeless
 
Oh, the actual 3. Don't come across that one very often
 
Wait... Is that the cold medicine talking?
Yeah. It was 3 I think.
 
bbl
 
Haven't got to play 3 that much at all. It's one of the few that fell through for me because it was hard to find
Some of you guys might like this, I made that in 2013. Combines Battle music from Final Fantasy I-IX:
All orchestrated & stuff
And I swear I wrote every single note on there, save for one song at the end that was insanely difficult (so I got a MIDI file)

@Phrancis Ever listened to The Black Mages?
 
Oh yes
I find them lovely
 
I actually like the Chrono Trigger OST more than the FF soundtracks
Chrono Cross also has a good OST
 
Chronos have awesome STs too
 
I'll have to have a listen to what you've done when I get home
 
It was in the works close to 10 years before I put it out there, hope you enjoy :)

Q: In the word "Scent", is the S or the C silent?

PimgdSo I saw a post on a funny pictures site... "In the word "Scent", is the S or the C silent?" And I thought I could ask about it here. In particular, how does the pronunciation of "scent" differ from "cent" and "sent"? Small audio references would help me in particular.

> You've earned the "Famous Question" badge (Asked a question with 10,000 views) for "In the word “Scent”, is the S or the C silent?".
 
@Vogel612 I'm still confused, you are working or still on school?
I'm also not awake at all
 
@skiwi it's... complicated??
Something along the lines of 80% work and 20% "school"
 
Okay... and you are doing both by yourself? Or does school make you do work, or work make you do school?
 
the latter.
 
Ah i see now

If I have a Maven dependency that has a dependency as well, then that dependency should be automatically copied to the classpath, right?
To answer myself; yes

Am I too impatient asking for some more input on codereview.stackexchange.com/questions/63066/… ?
 
@Christoph You've got two answers
What are they not providing that you are looking for?
 
The second answer re-raises a point I'm not sure of (problems with the overall container-ness of my container, as it might suffer from the same problems as vector<bool>) and asks anyone with experience with this for clarification (last paragraph)
 
hmmmh
I dislike your way of whitespace really, it's distracting me
You've got too much newlines between different sections
and too little whitespace between operators
good example is this
    };



    class const_proxy : public proxyT<true> {};

    value_type* data() {return data_.data();}
    const value_type* data() const {return data_.data();}
    void clear() {data_.fill(0);}
I also don't like your variable names, you use i as argument here and there
 
Point taken, the spacing is not consistent. How many newlines between sections do you prefer, and what do you refer to with "section"? the pair of bidirectional operators for example?

Variable names could indeed be clearer, I've already worked on that in my current version
 
well I'm used to java which is mostly 1 class 1 file
But I'd have maybe 2 newlines between classes and 1 newline between implemented functions
I'd also NEVER make implemented functions exist on one line.
 
9:52 AM
implementations in one line are already spread out. Also, as I have added a lot of comments for doxygen, members are now spotted more easily and don't stick together any more
 
value_type* data() {return data_.data();}
?
 
unclear or does it just look silly?
 
it's on one line, I'm not sure it should be.

Can recursion be so bad that it almost kills your program? Even though it doesn't use full resources of the PC
 
11:15 AM
yes
 
I don't know exactly what is going on here, but I did mess up something badly
 
@Mat'sMug not yet
 
I think we should be careful what we recommend/redirect to SO:
IMO this question is off-topic, since it involves "How to add a feature to or solve a problem with your code". It would be a better fit on StackOverflow. — BCdotNET 3 hours ago
It's a gimmeh-teh-codez question
Not good anywhere on SE

@rolfl Did you happen to run anything worth optimizing on Java 8 yet? My Metaspace is getting full and I'm trying to find out the consequences of it
Appereantly it's supposed to be like 90% full
 
11:42 AM
@rolfl look at the "This Year" users page (rep)
 
I may just rewrite this recursion to iteration
Wow... this bug
I had a bug that was caused by a infinite-length regex match
Not sure if that's the best explanation
(?i)^[a-z]{2}\\d{2}[a-z0-9]{11,}$ <-- But here the the full regex can be an infinite amount of characters
Well not really a bug, more a performance issue that made it took days if not years, which possibly worked hand in hand with using recursion over integration
 
12:10 PM
@Mat'sMug Hah, thanks. first to 50K? hmmm. Maybe not.
@skiwi I am not writing anything work related in Java8 yet.
IBM Java 8 is not yet released.
1 more month
(I have pre-release versions, but no IBM product is on it yet
As a consequence, there's no slow stuff yet to optimize ;-)
 
@skiwi I think we went over this in this chat a couple days ago... and you said "it works fine, it doesn't match infinitely at all"
or something along this lines
 
@rolfl Fun times for you!
@Pimgd Must've been 2 weeks at least... but I might vaguely remember something
Well it does not match infinitely... it just matches for a very long time
 
Sep 11 at 9:10, by skiwi
Does anyone know how to specify a regex that never matches? Situation: I am using a regex to determine if I should wipe out a character or not, in the default case I do not want to wipe out any character
 
@Pimgd Ah no, it's not that part that's at error now
 
@skiwi That makes no sense.
That regex should run very fast
 
12:14 PM
The regex itself runs very fast
But I'm searching a huge graph with it
And when it's a length-bounded regex it can stop once it knows it will not find anything anymore
But this thing will not prematurely stop
 
OK, so that one can stop after 16 or so characters?
Oh, no, it can't. sorry.
 
Back to the IBAN number specification
> The IBAN consists of up to 34 alphanumeric characters, as follows:

country code using ISO 3166-1 alpha-2 - two letters,
check digits - two digits, and
Basic Bank Account Number (BBAN) - up to 30 alphanumeric characters that are country-specific.[1]
So there is an upper limit which I didn't consider before, but it's still high
 
34 is not high.
 
It is if every symbol has about 6 alternatives attached to it, say 3 on average
Then you get 3^34 paths to follow worst case
 
It's an automaton.... not ideal, but faster than the alternatives.
 
12:19 PM
I should put this code up for review, but it might not be explained well enough to actually see what is going on
And it depends on a bunch of classes that are just data holders but would also need to be put up on CR
My code is exploding somewhere and I'm unsure of how to solve that
The issue that I have one sentence, and due to the nature of my program, I paste every symbol after eachother and remove whitespaces, and then the graph suddenly gets huge
 
But your regex is anchored at both ^ and $ .... it's not exploding from there?
 
Might the anchor be the issue?
 
I have this sense of deja-vu.
There is nothing in your regex that requires backtracking. Your regex is an O(N) operation on your string.
 
@200_success you didn't like my rewrites?
 
Yes, the regex itself is fast, I believe you need to see the full code to understand what I am doing
 
12:29 PM
The poblem with ' exploding' performance is in how you are setting up the regex, how you are feeding it stuff
 
The amount of possible paths my code needs to follow overflows inside a long, that might be why it takes so long
I'll do a final try to explain what I am doing without showing code so far
 
@Malachi You took a question that says "How do I do unit testing", and made it "what do you think of my code"..... Next time you ask a question on Code Review I will happily edit the title and say: "does my ass look fat in this thong?"
4
@skiwi The regex is not the problem, the surrounding code is....
 
We just hung up an XKCD print. We now have a real programmers office.
4
 
though the regex could be faster with a limit on it if you apply the regex a lot to long, non-matching strings.
 
In steps:
1. As input I have a `List<Word>`, logically formatting a line of text
2. Each `Word` consists of a `List<Symbol>`, being the letters
3. Every `Symbol` has a `List<SymbolChoice>`, being the alternative letters which it could also be -according to the OCR-
4. I create n-grams of all the words I have
5. I convert the obtained n-grams to a `List<Symbol>`, consisting of the symbols inside the words of th en-gram, without spaces
6. Of every `List<Symbol>`, I construct all possible symbol-choice-sequences via recursion
 
12:35 PM
OK, so you have a trial and error system of evaluation, and you want to identify success soon.
 
And the IBAN consists of alphanumeric characters, and regular letters also are alphanumeric characters
 
Qhy the n-gram? Don't trust the space-recognition of the OCR?
Also, how many ;'n' in the n-gram?
 
@rolfl It's a combination of not trusting it and clients that randomly place spaces as well
@rolfl I don't know, the maximum can be the length of a sentence and it will happen
 
OK, so your problem is that, with just a few words, and a few 'choices', you suddenly baloon up your number of words....
 
correct
 
12:41 PM
That's not the fault of the regex.
 
I think I can do nothing else than limit the choices? (They have a confidence level attached)
 
You can prioritize them?
 
It's not the fault of the regex, but it can be solved by supplying a bounded regex that is as narrow as possible
 
my IBAN is like NL## INGB 000# #### ##
 
@rolfl Yes, OCR provides one
@Pimgd If it only were so easy as just supporting Dutch IBANs ;)
 
12:42 PM
No, I mean to show that the IBAN can contain spaces in text
 
He's stripping the spaces.
 
@skiwi powershell seems pretty descent
 
Ah, to make it more fun, I actually strip every non-alphanumeric character before even applying the regex
(Because people also tend to pot dots (.) or hyphens (-) in their data)
 
@skiwi - sounds like you know what you need to do, but not how to do it.
You need to convert your alternate symbols in to a generated stream in descending priority order.
 
@rolfl Kind of, limiting the possible choices to 3 might prevent explosion, but it is kind of crappy to not use everything you have
 
12:44 PM
@janos It moves down in a fashionable manner?
 
A 'generator' of sorts.
Then you can filter that generator on the regex match.
and limit it to a bound of generations
 
Yeah...
Limiting might be the only solution
 
@Pimgd what do you mean?
 
Other question, if I have this regex: [^a-zA-Z0-9], and try to match # with it, then it should match, right?
 
@skiwi yes it should
 
12:48 PM
^^^that
 
@janos pretty descent
 
Somehow they are still appearing in my string
 
well, then you code ain't doing what you think it does ;-)
the regex will match # .....
 
@skiwi I would first check only for lines containing the countrycode and digits (for accounting number).
After isolating them (including alternative characters) I would provide country specific regexes as e.g in germany you only have numbers in the BBAN. Also recognizing digits with ocr is most of the time done good.
And last I would change the ocr engine ;-)
 
@Heslacher I think you are oversimplifying the situation :) Though the call on going down from a generic IBAN to country specific IBANs is an option
 
12:53 PM
Interesting concept of reversal.... @Heslacher - I was assuming that the 'candidate' recursion was happening to check for more than just IBANs
But, you can build your own automaton that does an IBAN-valid descent of your data and only reaches the end if there is a valid IBAN.
 
@skiwi what ocr are you using ?
 
@Heslacher Tesseract OCR
@rolfl Yes, this will need to work for every possible regex and/or predicate, hence it's not IBAN-specific, though IBANs are currently the most challenging case
 
Then you should for sure check alternative characters ;-)
 
On the plus side, I noticed why my # appears in the string
 
because you did not remove it?
 
12:56 PM
^ Yes
