ormlite creates tables with columns in wrong order
[[ Sorry for the late answer. ]] I cannot retrieve rows by queryId without knowing which column index the id field will be! Why does this happen and how can I make the column order consistent? ORMLite is using reflection (or the table configuration file) to determine the field order. For some reason when it goes through your entities, reflection is generating the field list in an order you aren't expecting. "Don't ever rely on the defined order of fields in any database. This is not just an Android tip, it's just good database practice in general." This is a very good tip. where queryForId(Integer.valueOf(resultArray[2]) requires me to have only the id and know EXACTLY what index the id will be in. Sure but since you are doing your own custom query, you can specify the

recvmsg linux receive wrong data
You don't update the iovecs in your send/recv loops, so you will repeatedly send the same prefix / recv into the beginning of the data buffer if the data is too large to transfer in a single network packet. I would use a common function for both send and receive to update the iovec: /** * Shrinks the iovec associated with a msg by a given number of bytes. * * @msg The message whose iovec needs updating. * @bytes Number of bytes to remove from the beginning of the iovec. * * @return Returns 0 iff the updated iovec is empty. */ int update_buffer(struct msghdr* msg, size_t bytes) { while (msg->msg_iovlen > 0) { if (bytes < msg->msg_iov[0].iov_len) { msg->msg_iov[0].iov_len -= bytes; msg->msg_iov[0].iov_base += bytes; return 1; } b

All their servers have names BLU0-SMTP<somenumber>phx.gbl. Believe me or not, but servers with two digits in their name are OK, but those with three digits are not.

Best fit from a set of curves to data points
You need two elements in order to have a fit, the data(which you already have) and a model space(Linear Models, Gaussian Process, Support Vector Regression). In your case your model has the additional constrain that some data points should be weighted differently than others. May be something like this works from you: from scipy.interpolate import UnivariateSpline temp = np.asarray([10, 9.6, 9.3, 9.0, 8.7]) height = np.asarray([129, 145, 167, 190, 213]) f = UnivariateSpline(height, temp) Now you can evaluate f wherever you want: test_points = np.arange(120, 213, 5) plot(height, temp, 'o', regular_heights, f(test_points), 'x')

Ways to animate bezier curves with AS3?
Hmm. Perhaps you should post your used version of TweenMax to properly debug the issue. There seem to be several of them, some use asynchronusly dispatched "update" events, some employ an enterframe listener, thus making sure each update routine is called each frame. So, graphics jittering can occur in an asynchronus scenario. On the other questions: Yes, you have to redraw the graphics object in question, this involves calling graphics.clear(). See, the Graphics object is a blackbox entity, you can't directly reach a control point of a curve to tween it somehow. So, in order to change a point on a curve, you have to redraw it. A more efficient way would be emulating a tween on your Sprite directly, via an enterframe listener and a function similar to Strong.easeOut used in tweening t

point of intersection 2 normal curves
You can use uniroot: f <- function(x) dnorm(x, m=14, sd=0.9) * .6 - dnorm(x, m=16, sd=0.6) * .4 uniroot(f, interval=c(12, 16)) $root [1] 15.19999 $f.root [1] 2.557858e-06 $iter [1] 5 $estim.prec [1] 6.103516e-05 ETA some exposition: uniroot is a univariate root finder, ie given a function f of one variable x, it finds the value of x that solves the equation f(x) = 0. To use it, you supply the function f, along with an interval within which the solution value is assumed to lie. In this case, f is just the difference between the two densities; the point where they intersect will be where f is zero. I got the interval (12, 16) in this example by making a plot and seeing that they intersected around x=15.

How to plot density curves for each column in R?
ggplot needs your data in a long format, like so: variable value 1 V1 0.24468840 2 V1 0.00000000 3 V1 8.42938930 4 V2 0.31737190 Once it's melted into a long data frame, you can group all the density plots by variable. In the snippet below, ggplot uses the w.plot data frame for plotting (which doesn't need to omit the final refseq variable). You can modify it to use facets, different colors, fills, etc. w <- as.data.frame(cbind( c(0.2446884, 0.0000000, 8.4293893), c(0.3173719, 0.0000000, 4.9985040), c(0.74258410, 0.08592243, 2.22526463))) w$refseq <- c("NM_000014", "NM_000015", "NM_000016") library(ggplot2) library(reshape2) w.plot <- melt(w) p <- ggplot(aes(x=value, colour=variable), data=w.plot) p + geom_density()

SVG convert polygon to curves conversion in Javascript
I assume, that while polygonizing, you sampled points on the curve, and joined them with straight lines. The reverse process is curve fitting. You want to do a "Hermite fitting of curve through a set of points". A little search will help you out. There are more such fitting algorithms. This is maths based and the under the hood solution to what you want. This is also how most such problems are solved. If you want a quick solution, you would have to find a library that does it for you. i.e take a set of points, and fits a curve through them. Note: I assume that fitting a curve through more than 4000 nodes is going to be costly. You could try it and see the performance for yourself, as I am not sure how costly would this be. But, I would suggest that if you needed to maintain the accura

Python: Pyplot in loop --> curves are cumulated per iteration, not separately plotted
I think the confusion comes from the fact that you dont use the OO interface. Pyplot is convenient but handles a lot of things in the background making you unaware of whats really going on. In your example you create a figure and axes on-the-fly and keep plotting in that same axes. Clearing the axes before plotting would solve your issue, try adding pyplot.cla() as the first line of your loop. I would prefer making a figure and axes object: all_Lists = [list(np.random.randn(30).cumsum()) for i in range(10)] fig, ax = plt.subplots() for n, curv in enumerate(all_Lists): ax.cla() ax.plot(curv) fig.savefig()

Linux users', specifically Apache, permissions settings, [Linux noob :]
usually any daemon will need to access a number of ressources. it is therefore good practice to run each daemon under a special user:group, rather than nobody:nogroup. traditionally (e.g. on Debian systems) apache runs as www-data:www-data. finally, user permissions take precedence over group permissions (which in turn take precedence over other permissions). this means that a directory where the user does not have write perms but the user's group can write is effectively r/o for that user (but not for other members of the group)

Exec(Linux). How it functions internally? Linux executable attributes(rlimit)
The RLIMIT_CORE is used to place a limit on the amount of info that coredump is allowed to produce, before it is aborted. Once this limit is hit, no more info is logged and the message Aborting Core is logged to the console. From the man page of core : A process can set its soft RLIMIT_CORE resource limit to place an upper limit on the size of the core dump file that will be produced if it receives a "core dump" signal. Use setrlimit() to configure RLIMIT_CORE to a larger value to obtain complete coredumps. The most common format of executables/shared-objects is ELF. On Linux, the dynamic loading and linking of these shared-objects is performed by ld.so ld.so is loaded in the address space of a newly created process (by exec in this case) and executed first.

Write C++ on Windows but use Linux System calls through a Linux emulator
You've already tagged your question with Cygwin. That seems like the best solution for what you want. Cygwin is basically a collection of programs which emulate a GNU/LInux environment through the use of a DLL (cygwin1.dll) which acts as a Linux API layer providing substantial Linux API functionality. Here's the link to the documentation for its API Edit: Most of the Cygwin source code that I've looked at is written in C++ and makes system calls using MS Windows API to do provide the *nix emulation. The source is well written and very readable (even to to a non-C++ programmer such as myself). I think using Cygwin would be a good transition from programming on Windows to a GNU/Linux environment.

However, it should also be noted that several (not all, by any means) distros ship with mono by default.

GWT Generates the wrong classes in the wrong files (ClassNotFoundException)
The problem was that a generator is instantiated once, and the generate method is called again on the same instance each time, thus any properties are effectively cached. I was using a cached ClassSourceFileComposerFactory instance with a method called getComposer() which would check if null, if it is, instantiate, otherwise return. This was leaving a cached ClassSourceFileComposerFactory which would always have the same class in mind.

Changing an Entity creates a new one as well
i think this is entity framework issue,you may use "Context.context.Projekt.Find(id)" in your "izmjeniProjekt" instead of your function "getProjektByID",maybe passing and getting types with the functions is the problem, by the way your naming is awesome ! the problem is obvious, entity framework recognizes your "Projekt" as a new entry, so the problem is the Key of your database table, you probably used code first migrations to creating your database and you didn't specify the key, but by the way, you have the id, in my opinion its not necessary to get the "Projekt" from data context, just use it! maybe what i'm trying to say is not clear so watch this video ( you will see your problem there ) to have a better understanding of entity framework.

Decorator that creates classes
Not possible. Making 3 classes is easy. Assigning the results to 3 variables, though? That violates Python's scope rules. @mc_me class Test: name = "Test" is equivalent to class Test: name = "Test" Test = mc_me(Test) There's no way for the decorator to say that it wants to create some more variables and assign to those too. Even if you somehow managed to get it to work (probably only at module or class scope with inspect craziness), Python would have no way to know that references to TestSuper or TestExtra should refer to the variables created by the decorator when compiling the bytecode.
