It's faster to write the code yourself than it is to fix up the junk produced by those AI "assistants".

Code generators have been around for decades for specific purposes, and can work well, but these things are pretty much useless.

Even worse: the junk being deliberately fed to AIs is already at the stage where the results are useless BUT those results are blindly believed by many people BECAUSE they're generated by AI and therefore supposedly automatically correct!

Think Google's disastrous launch of their image generator which would under no condition generate Caucasian people because it had been fed exclusively black people because of the political ideology if its creators.

I've noticed similar things happening with inputs of climate models while working for our national weather agency, inputs which were deliberately filtered to exclude historical temperature extremes because the people in charge wanted a specific, politically motivated, output. And that wasn't even AI yet, but the results of those models are used as input for AI to make more sweeping predictions!

Now imagine similar things happening to AI being used to perform medical diagnosis, or worse yet medical procedures, just to give one example.

Remember that ChatGPT has no real time connection with anything, it only knows that data was loaded into its database, which is a very selective dataset that is several years old.
That's part of the reason for all the disclaimers on not using it for financial advise, any advise you would get would of necessity be years out of date.

Siri, which just interfaces with existing search engines after using a speech to text algorithm to turn your voice input into a text string for an existing search engine (and I guess Google assistant and Alexa do the same thing) are far better suited for task. More isn't even needed, separation of concerns is in place.
You could probably make something that'd use a voice to text system to feed input to chatGPT but would purpose would it serve? ChatGPT is just a toy, a proof of concept and marketing tool for its creator. And a major annoyance for places like Stackoverflow that now have to contest with fools using it to create silly "questions" and "answers" the poison the site.

Iiyama and MSI haven't let me down yet. Had 1 Iiyama fail on me last year, after nearly 10 years.

"live user counters" are a lie! It's technically impossible to create such a thing as you never know whether a user is still actively using the page you're counting them as being on (or indeed the site).

All you can hope for to do is create a counter of the number of times a page was requested over the last say 5 minutes.

The best thing, and what most sites use, is to not allow a user to post anything until they verify their email address.

Not that it'd matter much in the specific case of the homework kiddo not responding to comments, as that's never their intent. They just dump their assignment on a dozen sites and if they have no working solution they can turn in appear within a few hours move on.

Ideally you want a mix of experience and new blood. And why do you think experienced people can't be motivated or interested in new things?

What's more important in a team than anything else though is that the people can work together well. If you have 10 unicorns, each the top expert in their field, but they aren't talking and in fact actively sabotaging each others' efforts because they disagree on things and can't compromise that's worse than having no people at all. Something that happens with juniors as well in my experience, in fact even more so as they tend to be laser focused on religiously following the mantra drilled into them in their training, with no interest of capability to look beyond that way of working. A good senior can help guide those youngsters and teach them how things work in the real world.

As a business owner, you obviously make your own rules in this, as long as they stay within the TOS of each service you use.
That said, don't spam, post things where and when appropriate only, and tailor each post to the venue (as with all marketing efforts).

As an employee, follow the rules and guidelines set out by your employer (which in my case say NO social media posts even suggesting I'm acting on behalf of the company at all, and restrictions on even private use that may influence the public's opinion of the company based on my actions. Which actually goes beyond social media use, I can in theory be fired for getting a speeding ticket as we have a company policy that nobody should break any traffic laws, we're supposed to be a good example of responsible driving, working for a company in the automotive industry).

JSP is very old technology, I'd not advise it for new projects but if you're interested in learning it for the same of things or to work on maintenance of legacy code it's quite viable.

Yes, JSP is essentially a blend of servlets with html. If you look at the compilation stages of a JSP into a runnable artifact this becomes immediately obvious.
A JSP is first transformed into a Java servlet source file, which is then compiled into a Java class that is deployed to the application server.

But directly writing Java code in JSPs is much frowned upon, far better to make taglets and other fragments and include those in the main JSP, keeping it as clear of Java code as possible.

Yes, servlets can make use of any and all Java code, except those parts that create user interface components on screen (obviously). So most AWT and Swing is not going to do anything, though the image manipulation parts work, you just need to stream the resulting images to a ServletOutputStream rather than a Swing component.

Most people who have instagram accounts are bots, whether they're computer programs or brainless humans. Just contact them and pay them to follow you.

It means someone who can do everything, frontend, backend, server administration, database administration, security, graphics design, everything.
And don't expect to get away with being good at one thing on their bucket list and merely decent at the rest, you're expected to be a world expert at everything while working for peanuts.

The more delusional the hiring (or IT) manager, the longer the bucket list of skills, tools, and libraries you're required to have mastered, and the more likely they will be to fire you for incompetence the moment it shows you're less than perfect in any one aspect of the job.

In finance, or anywhere where precision is important, you use fixed point numbers (integer math), not floating point.
In finance moreover, typically (and this is an internationally recognised standard employed by banks) only the first 5 digits are considered significant.
Anything over that is irrelevant.

Just do like all the other spammers do, spam your website on Daniweb and every other forum website that doesn't have a strong anti-spam policy (or has one but doesn't bother to enforce it).

So you want someone to do your homework (because that's very clearly what it is, your school homework) for you.

The answer to that from any programmer worth the job name is HECK NO.
We don't want fakers with diplomas they didn't earn in the profession as it makes our work that much harder. If you can't even do your homework, you're not going to be able to program yourself out of a bug report or feature request at even the most junior level if you ever got hired, and someone who can will have to do double hours to cover for you.

better yet, copy/paste the code into a code block.
I for one (and hopefully everyone) won't open attachments...

A GOOD training course gives you time to experiment and practice along with the course material, and knows you need that time to gain proficiency.
They also make sure they can meet the needs of both faster and slower students.

Which is what in my experience many Udemy course creators understand.

flipping schemes like this aren't the purpose of places like Etsy...
And most of them are scams anyway, promising shipment of items that don't exist until they are sold, mostly. Often the seller takes the buyer's money, invests it in something (often crypto), and either never ships the actual goods (because they never existed) or waits weeks or months to make a profit on investing the money before buying and shipping cheap knockoffs sourced from aliexpress.

Etsy has pretty strict policies that help reduce the incidence of such schemes, by handling the payment process themselves and being able to force chargebacks on the seller in case shipments don't arrive in a timely manner.
I've had to use that once so far when a seller had marked an item as "shipped" (which is when they get paid, Etsy holding the funds in escrow until then) but a month later having to admit that they'd never actually even had the item...

If you have a quality product though, and good customer service, your sales will take off.

spam forums like this one with the URL of your website, apparently.
A lot of people seem to do it so I guess it works.

Ever more government agencies and some companies won't work with a supplier until they have specific ISO certifications, and this is the latest fad among those.

looks like a spam account that forgot the link to their website in the post and profile...

Derby was included in Java7, it isn't in Java17 as it was removed with the release of Java9.
https://stackoverflow.com/questions/53911999/where-is-the-derby-jar-file-within-my-java-11-installation-on-mac
Java11 saw a whole bucket list of stuff removed as well, and some more pruning has been going on since.
Mostly these are features that were duplicated from Java EE or are simply almost never used any longer (like CORBA).
https://www.oracle.com/java/technologies/javase/11-relnote-issues.html
They're also slowly (and finally) removing deprecated functionality, especially where there are security implications.
http://cr.openjdk.java.net/~iris/se/11/latestSpec/api/deprecated-list.html

Together with your JDBC URL being incorrect that's why your application isn't working on your Mac, which no doubt comes with a version of Java way newer than 7 installed (if you're still using 7 on your computers, it's past time to replace it as it's no longer supported and has some known security vulnerabilities among other things, and with all the language changes since you shouldn't be writing for it anyway unless you're maintaining a very old legacy system where for some obscure reason the machines it is running on can't use a later JVM).

do your own homework, or at least try and show where you are stuck.
Us doing your homework for you helps nobody, least of all any of us who may end up with an incompetent idiot who got his diplomas by cheating.

It'll just invite more spambots, not just to post the posts to be paid out but even more of them to upvote those posts.
Unless you can take care of the glut of spam accounts and homework kiddos (who'd no doubt do the same for their classmates) you'd just end up paying out a lot of money for more useless posts.

Sounds like a poor project setup, and not having your classes as part of packages makes that even worse.
Not using a normal naming convention for classes makes things worse still.
Not knowing your tools doesn't help either.

Google probably switched to a lower resolution provider.
Whether that's forced because of unavailability of other data (maybe a supplier went out of business, or isn't allowed any longer to sell them the data) or to save money (lower resolution images are cheaper than higher resolution ones) I don't know.

As to people wanting their property blurred out, it happens and often for good reasons beyond "muh privacy" (though that is in itself a valid reason). For example I met someone who has to have an extensive private security detail after several attempts on their life over the last several years, including attempts to shoot burning material at her house to cause fires, and an attempt to drive a truck through her fence and into her house in an attack similar to the 1983 Beirut attack on the US Marines.
Her place has not just been blurred, the entire area has been replaced with fake data for her protection (it now looks just like the forested surroundings, even the access roads are gone).

And as said, military installations tend to be either blurred or get the same treatment and are simply not there at all. Or if they are they tend to have low resolution images only by design.

It tells you EXACTLY where the error is and what the error is. You're passing a null value for an argument where an actual value is required.

It's for you to figure out what that actual value should be.

having worked until very recently on ACTUAL airport software, I can tell you this is indeed not anything real. It's a simple homework assignment.

Nothing wrong with those, they're supposed to be simplified. But they're also supposed to be implemented by the pupil or student, and not strewn around the internet in the hope someone will provide you with an implementation you can then turn in as your own and get a good grade for without having put in the actual work.

All depends on what you need it for...
A web application needs a server to run on, lots more infrastructure than a standalone desktop application.
Of course if you're just interested in a single static page, then yeah, it might be easier to make a rough outline in html and just ship the html file. But that's not what a complete product would look like.

So you want us to do your homework for you.
That's not going to teach you anything, and would end up with your future colleagues having an unqualified coworker who graduated without deserving it.
Instead do it yourself and then if you don't feel comfortable maybe ask specific questions about details.

An easier approach would be to store just the ingredients list per recipe in json or xml, allows you to use already existing languages to create an application that can combine those ingredient lists into a shopping list.
And if you want you can create a recipe repository to go with it, with the recipe and ingredient list stored as separate but linked entities (the links being either database records or other json or xml documents linking to the separate files).

That way you can also easily store everything into something like mongodb and use its advanced search capabilities so you don't have to write your own search engine either.

Which shows again how important it is to have proper code review processes and things like that in place, even for open source projects.
A properly run project wouldn't have had this problem as the code in question would never have been approved for inclusion in the first place.

Do you have a few BILLION dollars to invest in that venture?
As that's what it'll take to create a viable competitor to both those giants (or even facebook alone) and the marketing to get it a large enough user base to get to the point it has critical mass and doesn't get swamped (which you have to achieve quickly).

And most of those billions won't be the coding (that'll be mere tens of millions for the initial investment) but hardware, marketing, hosting services, etc. etc. etc.

I've tried several, and the only one I kinda like is the one provided by IntelliJ.
It seems to create the least convoluted code, but as anything it takes time to learn to use properly.

pumping 5 million rows is going to be a problem to do in a few seconds over any kind of network connection, and if it then needs to be parsed into some output format and then pushed over another network connection to yet another computer to display (worse still if it's going into a web browser) it's pretty much a lost cause.

Just getting the query executed and the results dumped onto the query console on the physical database server is going to probably take more than a few seconds (especially if it's a more than trivial query with more than 1-2 columns).

The main problem at the moment is that there has been so much misinformation and lies from everyone (plus simply changing data causing people to update their opinions on matters, something that is often not understood to be possible in our highly polarised society) that many people no longer trust anything anyone says (or very selectively only trust what their chosen ideological leaders tell them, even if those leaders change their mantra radically overnight without telling people why).

This level of mistrust is bad now, when we're dealing with a relatively mild disease that kills only a very small percentage of those who get it and has serious long term effects in a very small percentage as well (mind that given the number of people who get covid the actual numbers are still high, but that's statistics for you).
What worries me far more is what will happen when that mistrust and refusal to do the smart thing "because they're all lying to us anyway" will do when another, far more lethal, pathogen emerges. Something like an airborne strain of ebola or measles that nobody has natural immunity to and is highly resistant to medication and vaccines.

sadly the politicisation of covid has caused a lot of people to think that way.
I've seen people flip-flop on it even. A leftist friend before Biden became president was all opposed to "the Trump vaccine that's going to kill everyone", there was no virus, Fauci was the literal devil. The day Biden took office those same vaccines were suddenly the best thing since sliced bread, covid was a killer disease created by Trump to kill everyone, and Fauci was literally god.
Conservative friends flipped the other way.

To a degree I see the same with people I know in other countries as well.

Personally, I think both attitudes are idiotic.

yeah, everything is there. I've created symlinks from the files inside the XCode installation to places where CMake can see them.

I'm trying to use CLion (thus CMake) to create OpenGL applications using C++ on MacOS Monterey using a 2021 (so M1 based) Macbook.
Glew2 and GLFW3 are installed correctly using Homebrew, XCode and the commandline tools are installed as well.

Creating and compiling/running through XCode works fine, but using the same libraries and C++ source code from CLion doesn't work.
First it can't find the OpenGL library headers, I fixed that by placing a symlink from their location inside the XCode application libraries in a public location.
Problem is that now I get a linker error stating that Glew and GLFW are Arch64 and it's trying to build an x64 application from CLion. When forcing CLion to compile to arch64 I get an error that the OpenGL core libraries it's trying to link to are x64. Apparently XCode is smart enough to link to the correct libraries automagically but CMake can't find them.

Any ideas as to why this happens and what to do to resolve the problem?

start by using the standard containers.
https://www.cplusplus.com/reference/list/list/sort/ shows exactly what to do...

That's the c++ way.

VB has not been abandoned. VB6 is however so old nobody should be surprised if it's no longer being maintained, it's been long since replaced with new versions.

Unless you have access to a hardware Python interpreter, you're not going to use Python to build an operating system.
And even if you have, you're unlikely to succeed due to the limitations of Python when it comes to low level system operations.

Only way to be certain is to talk to a lawyer, who can then ask them...

But apart from Dani's suggestion, which is a good one, it can also mean you're not allowed to share the data with others (as that'd be potentially illegal, especially in the EU, but also cost Facebook money as they themselves make a lot of money selling that very data).

Having been involved with multiple government agencies and departments over the years, I've more than a bit of insight into what they need.

1. good support from an external party handling the servers
2. excellent security
3. guarantees that no data will be stored or handled by computers in other countries
4. integration with their existing IT architecture

What this comes down to is that the solution chosen will usually be something like MS Teams or Citrix.
Zoom should NEVER be used by anyone as it's horribly insecure. Slack is good, don't get me wrong (we use it extensively where I work at the moment) but the company behind it simply doesn't have the resources to meet all the above requirements.
Zulip is as bad as Zoom.
Skype falls apart when it comes to requirement #3, plus it doesn't really work well for meetings with large numbers of people.
Discord falls apart when it comes to #3 as well, and with the reputation it's "for gamers" won't appeal to managers, no matter how good it is in general.

Beating yourself on the head with a sledge hammer while dancing barefoot on white hot razor blades blindfolded.

C# is important as well, as it's what Unity uses.
Java for Android phones, obviously.
C++ for those using Unreal Engine.

Both Java, C#, and C++ have (to various degrees and with various restrictions) the option to be used for cross platform development.

However, many games are more scripting into a pre-built game engine either developed in-house or purchased externally, and that scripting is usually done using either Lua or some custom language specific to the game engine.

sit down and think about what you want to do, what the program's structure will be as an object oriented system.
Don't just mindlessly start coding.

And that includes homework assignments.

or just pay google to get boosted in the search rankings...

sorry, but such an app simply won't work unless it finds an unsecured WiFi network to connect through.
Which is probably exactly what it does.

It's not a VPN in that case, it's a network sniffer and probably a nasty one that tries to brute force poorly secured networks as well.

First programs I wrote I wrote on double spaced paper, then had reviewed by someone else who wrote his comments in between the lines.
Then the corrected program was written again on double spaced paper and submitted for review.
Rince and repeat until all parties involved are happy with the code at which point it was entered very carefully, double checking each character before entering the next, into the single computer we had for the department.

I continued the practice for a while after, writing the beginnings of a chess engine in Pascal while on vacation in a hotel in Austria, on a yellow legal pad. Didn't have a laptop, cellphones were pretty much non-existent and mobile data hadn't been heard of.

When I got home I entered the code into source files and compiled it.

And similarly I've worked with systems where the devices has SIM cards and a GSM plan but no data. All communication was done using SMS.
Bit cumbersome, but that's how things worked back in the day when mobile data plans were either unavailable, unreliable, and/or extremely expensive and the volume of data was very low.
