     I have written applications in Haskell using both methods (client/server, native) and they both come with their {dis}advantages. I realize this is more that you asked for but I have documented the upsides and downsides of both approaches in the hopes that it will help you make a more informed decision.

     More specifically the approaches I used were:

     • Web applications that use Haskell as the backend and Javascript/HTML for the frontend. Communication was done solely using JSON. No HTML or Javascript was generated on the backend.
     • Natively in pure Haskell using GTK2HS

     The upsides of the first approach are:

     • I was forced to separate GUI code from back end logic. It definitely made for cleaner design.
     • Haskell now has high-performance webservers [4,5]. It also has great CGI/FastCGI and database support if you want to write PHP-style scripts on third-party webservers. I used the latter approach and it worked pretty well.
     • UI libraries are good enough now where building a front-end in Javascript is quite a pleasant experience. I am very happy with Qooxdoo [2] but there are several options (jQuery, ExtJS ...)
     • Software Transactional Memory [3] makes it trivial to store concurrently accessed state on the server side. STM is the single biggest reason that this approach is viable and fun.
     • I liked that the UI was consistent and easily deployable to any platforms that could run a web browser. If your app has to run on Mac as well as Windows and Linux I still think this is the best way to go (more below).

     The downsides of the first approach are:

     • I had to deal with authentication and sessions even when I knew that this was a single user application. There are now frameworks (Yesod, Happstack ...) that help with this but I think it is accidental complexity that can be avoided by writing a native application.
     • I had to roll my own client/server communication protocol. Extending the protocol and making sure it was correct was painful on the Javascript end, but was an absolute joy on the Haskell end. I suspect this will be the case for any GUI-friendly-language/Haskell combination you choose.
     • A good chunk of my code ended up just marshalling and unmarshalling JSON data. This is less of a problem now because I think there are a number of Haskell libs to that claim to automate this [1].
     • Most hosts don't support Haskell applications.

     The upsides of second approach are:

     • all your development is in the same language and so it is easier to test.
     • Glade is a great for visually building GUI's and Haskell integration is extremely good.
     • deployment on Windows and Linux is easy.
     • GTK2HS is very good, complete and well documented.
     • The bindings also try to mirror the OO structure of GTK itself. There are downsides to this (see below) but the great advantage is that I was able to use documentation for other language bindings to fill in any documentation gaps. When I developed I was constantly referring to Python's excellent GTK docs.

     The downsides of the second approach are:

     • deploying a GTK2HS application on a Mac is god-awful and it looks ugly to boot.
     • Installing GTK2HS on Windows is non-trivial, on Mac it is an open research problem.
     • GTK2HS requires you to write very unidiomatic Haskell. There's mutable state all over the place and the lack of objects means that you're essentially writing procedural code.

     Hope this wasn't TMI.

   • Latency vs Jitter in Computer Networks

     There are two vital concepts in the world of networking and telecommunications that are used frequently, latency and jitter. There are, on the other hand, two separate components of data transmission efficiency.

     • Processing Delays: The time required for data to be processed by network devices like routers and switches.
     • Queueing delays: Time spent in a queue waiting to be transmitted before reaching the link to the destination host.
     • Transmission delays: time it takes to push the packet’s bits into the wire.
     • Propagation delays: Time the signal takes to propagate through the medium. It would be a signal through an optic cable.

   • Writing a C function to take in an english sentence as parameter and return the longest length word in the sentence

     Top Answer

     Answered Feb 12, 2021 · 2 votes

     The problem is in while (*s++ != '\0') {: you increment the string pointer before testing the character it points to. Just change to code to:

     for (; *s != '\0'; s++) { ...-

     Note however that the last word will not be tested the maximum length if it is not followed by some separator such as a space or a newline, which you would have stripped.

     Note that stripping the trailing newline is not required for longWordLength() to determine the correct count.

     Here is a modified version:

     #include <stdio.h>-int longWordLength(const char *s); // Function prototype-int main() { char str[80]; printf("Enter a string: \n"); if (!fgets(str, sizeof str, stdin)) return 1; // no need to strip the newline for this test: printf("longWordLength(): %d\n", longWordLength(str)); return 0;}int longWordLength(const char *s) { int count = 0, max = 0; for (;; s++) { if ((*s >= 'a' && *s <= 'z') || (*s >= 'A'&& *s <= 'Z')) { count++; } else { if (count > max) { max = count; } if (*s == '\0') break; count = 0; // reset the counter for the next word } } return max;}

   • English Language Regex in C#

     I think I found it, I tried the Basic Latin Unicode category, and it works fine so far. I used:

     "^[\u0000-\u007F]+$"-

     Its idea is about checking if the given text is in English and is written by using English letters only, in addition, it allows special characters. So, if the given text was like this "I met my friend in a café", it is considered as non-English text, as the given text should contain only English letters and avoid any other letters even if typed a name, place ... etc. this was exactly what I need. Thank you all.

   Apr 13, 2023 · Dispatch latency consists of an old task releasing its resources (wakeup) and then rescheduling the new task (dispatch), all of this also comes under context switching. Let’s look at an example to understand context switching and dispatch latency.

   What is dispatch latency?

   • It is the time taken by the dispatcher in context switching of a process from run state and putting another process in the run state. Dispatch latency is an overhead, and the system does no useful work while context switching. Some hardware provides multiple sets of registers per CPU which allows multiple contexts to be loaded at once.

   What is the difference between context switch and dispatch latency?

   • the kernel decides it has nothing better to do so it returns to user-space, taking another 10 nanoseconds. Here, the context switch time would be 40 nanoseconds, but the dispatch latency (as defined by the book's author) would be 100 nanoseconds. "Context Switch" is a process. "Dispatch Latency" is a latency, a.k.a. time.

    Jan 10, 2023 · Latency, or delay, is usually measured in time (fractions of a second, or microseconds). Minimizing this time interval is a critical requirement for many modern software applications across most, if not all, major industry sectors. Gaming and finance are key examples of areas of our economy where this requirement’s importance is most critical.
