I've been looking at alternatives for hosting your own maven repo on Github, but that seemed like a bad idea. Then I googled for how to host your maven repo on Tomcat, but that returned more results about how to use the Tomcat plugin for Maven, turns out a simple webserver with FTP access was enough...
Currently my SerializationProxy has a HashMap and uses the putAll to put the properties of the class
I want to punch myself in the face now... After debugging 15 minutes, I see this

}

@skiwi - I am beginning to like some of the sugar in Java8.... my new favourite method:

long nanos = System.nanoTime();

System.out.printf("Ran %s in %.3fms%n", name, time / 1000000.0);

Are people overusig the <li> element in HTML? Why do people insist that "any collection or group of things" must be classified as a list? If they wish to divide items in their markup, why can't they just use <div>?

> All 3 main types are used in Canada – in French and in English.[29][30]
Social Insurance applications for Canada use DMY format.[31]
Passport applications[32] and tax returns[33] use YYYY MM DD.

Nearly all English newspapers use MDY (MMM[M] D, YYYY).[34]
The default date format used by Microsoft Windows for English Canada for all-numeric dates (short-dates) is DD/MM/YYYY, and for long dates is MMMM D, YYYY in Windows XP and MMMM-DD-YY in later versions; for French Canada it is YYYY-MM-DD for short-date…

For a PDA a transition from one state to another work require some sort of an extension, because the transition req...
In the input you have a header, then a payload. You read the header, removing it from the input. It says you need X bytes to store the payload. You allocate the buffer and fail, there's no memory. Do you then A) skip through the payload B) leave the inputbuffer in a bad state where reading will result in bogus values?
Well, as long as you clearly lay out ownership for each reference, it gets manageable. When a function allocates a buffer, but passes ownership to the caller, then the caller is responsible for freeing. Also, you should always return the size of the buffer. This ends up using pointers as out-arguments; C++ has a much nicer mechanism with references.
Well, C has arrays but they're statically sized. Pointers can be used as arrays, but they don't know their size. So to avoid buffer overflows, you either have to use something like null-terminated strings, which is broken and error-prone and wrong, or return the size, so that you can do "for(i=0; i < length; i++) frobnicate(buffer[i];". That requires something like char* buffer; int buffer_length; int result = your_api(&buffer, &buffer_length), which I'd prefer over structs.
lol I have been saying it for some time now, I thought it was rather clever, and seems to fit with the logic I use to come to conclusions about things I know something about but am still not an expert.
@skiwi \w is not \p{L}. Per the Java documentation, the char classes behave according to Unicode, which means that it matches all alphabetics, digits, connectors such as underscores, and marks such as diacritics
I've created this so far, but it doesn't work as the regex is still wrong:
public final class DateParser {
private DateParser() {
throw new UnsupportedOperationException();
}
private final static Pattern PARSE_DATE_PATTERN = Pattern.compile("(?iuU)^.+([\\d\\w]+).+([\\d\\w]+).+([\\d\\w]+).+$");
public static LocalDate parseDate(final String text, final FormatStyle formatStyle, final Locale locale) {
Objects.requireNonNull(text, "text");
Objects.requireNonNull(formatStyle, "formatStyle");
Objects.requireNonNull(locale, "locale");
@skiwi It is correct, but suffers from catastrophic backtracking. Note that "." can also match all characters that "\w" matches. Note also that you require at least one character at the beginning ("^.+"). How to fix this: (1) make the prefix/suffix optional: "^.*" and ".*$" (2) consider using something like \W+ instead of .+ in the middle.

The !par statement is even wrong to me, as exiting early and not using potentially nested ifs is good coding practice imho (see programmers.stackexchange.com/questions/118703/…). Also, the ternary statement is largely only a personal opinion, I don't think it is any easier to read. — dirkk5 mins ago
coding standards on the other hand say that you should write a clear path and not dance around the fire 3 times before doing what needs to be done. if you would like to discuss further we can take this to chat. 2nd Monitor — Malachi5 secs ago

@amon where would you define the error codes? I'm thinking of placing them next to the function definition in the header as #define functionName_errorName errorCode
@Malachi well, I have to say I still disagree. One reason is that stylistic advice is not really what we are looking for (of course it is appreciated if something really stupid is done). But my main point is still that I believe (and many programmers agree with this coding practice), that returning early is good and avoiding nested ifs is a very good thing.

@dirkk as an aside, whenever I personally write early returns I try to make them as distinct as possible:
@Override
public boolean isValid(final Location instance,
final ConstraintValidatorContext context) {
if (instance == null) {
// Recommended, instead use explicit @NotNull Annotation for
// validating non-nullable instances
return true;
}
final String checkedValue = instance.getLocationName();
final long id = instance.getId();
@Vogel612 But as you can see, I already took it to chat, so I am not completly hopeless ;) So quoting from the help "Feel free to call attention to specific areas you are concerned about (performance, formatting, etc)." --> That's what I am actually trying to do
@Vogel612 I don't quite see what you mean with "make them distinct" in this example. This is just If (instance == null) return true;,, I don't see any difference in cody style to If(!par) return;

Frankly, to me this is very much opinion-based. I think the one liner is as easy to spot as before, especially because it is not surprising in this place. Checking for empty elements at the beginning of a function is quite expected, it would be different if it is in the middle of a long spaghetti-like function
IMHO; if you use guard clauses on 1 line, leave a blank line between your body and your guards. Those that are being protected need their breathing space too.
Yeah, that might be why I reacted so strongly against the fact the style was even commented on, because it seems rather useless to me. Except for a beginner code-styling comments are rather pointless to me, because there are a lot of different styles out there, and for a good reason.
