curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line

tldr

do curl cht.sh/go/execute+external+program to see how to execute external program in go

And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?

I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.

Nowadays you probably know, how to check the weather from the command line, but if not:

curl wttr.in

or

curl wttr.in/Paris

(curl wetter in Paris if you want to know the weather in Paris)

After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):

curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text

And now last but not least, the gem in this collection: cheat.sh.

The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.

With cheat.sh you don't need to install anything, just do:

curl cheat.sh/tar (or whatever)

you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).

But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.

Now you can simply do:

curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read

or even

curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件

and get your question answered
(cht.sh is an alias for cheat.sh).

And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.

One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.

The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.

The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh

Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?

EoS1: This is the continuation of my previous rant, "The Ballad of The Six Witchers and The Undocumented Java Tool". Catch the first part here: https://devrant.com/rants/5009817/...

The Undocumented Java Tool, created by Those Who Came Before to fight the great battles of the past, is a swift beast. It reaches systems unknown and impacts many processes, unbeknownst even to said processes' masters. All from within it's lair, a foggy Windows Server swamp of moldy data streams and boggy flows.

One of The Six Witchers, the Wild One, scouted ahead to map the input and output data streams of the Unmapped Data Swamp. Accompanied only by his animal familiars, NetCat and WireShark.

Two others, bold and adventurous, raised their decompiling blades against the Undocumented Java Tool beast itself, to uncover it's data processing secrets.

Another of the witchers, of dark complexion and smooth speak, followed the data upstream to find where the fuck the limited excel sheets that feeds The Beast comes from, since it's handlers only know that "every other day a new one appears on this shared active directory location". WTF do people often have NPC-levels of unawareness about their own fucking jobs?!?!

The other witchers left to tend to the Burn-Rate Bonfire, for The Sprint is dark and full of terrors, and some bigwigs always manage to shoehorn their whims/unrelated stories into a otherwise lean sprint.

At the dawn of the new year, the witchers reconvened. "The Beast breathes a currency conversion API" - said The Wild One - "And it's claws and fangs strike mostly at two independent JIRA clusters, sometimes upserting issues. It uses a company-deprecated API to send emails. We're in deep shit."

"I've found The Source of Fucking Excel Sheets" - said the smooth witcher - "It is The Temple of Cash-Flow, where the priests weave the Tapestry of Transactions. Our Fucking Excel Sheets are but a snapshot of the latest updates on the balance of some billing accounts. I spoke with one of the priestesses, and she told me that The Oracle (DB) would be able to provide us with The Data directly, if we were to learn the way of the ODBC and the Query"

"We stroke at the beast" - said the bold and adventurous witchers, now deserving of the bragging rights to be called The Butchers of Jarfile - "It is actually fewer than twenty classes and modules. Most are API-drivers. And less than 40% of the code is ever even fucking used! We found fucking JIRA API tokens and URIs hard-coded. And it is all synchronous and monolithic - no wonder it takes almost 20 hours to run a single fucking excel sheet".

Together, the witchers figured out that each new billing account were morphed by The Beast into a new JIRA issue, if none was open yet for it. Transactions were used to update the outstanding balance on the issues regarding the billing accounts. The currency conversion API was used too often, and it's purpose was only to give a rough estimate of the total balance in each Jira issue in USD, since each issue could have transactions in several currencies. The Beast would consume the Excel sheet, do some cryptic transformations on it, and for each resulting line access the currency API and upsert a JIRA issue. The secrets of those transformations were still hidden from the witchers. When and why would The Beast send emails, was still a mistery.

As the Witchers Council approached an end and all were armed with knowledge and information, they decided on the next steps.
The Wild Witcher, known in every tavern in the land and by the sea, would create a connector to The Red Port of Redis, where every currency conversion is already updated by other processes and can be quickly retrieved inside the VPC. The Greenhorn Witcher is to follow him and build an offline process to update balances in JIRA issues.
The Butchers of Jarfile were to build The Juggler, an automation that should be able to receive a parquet file with an insertion plan and asynchronously update the JIRA API with scores of concurrent requests.
The Smooth Witcher, proud of his new lead, was to build The Oracle Watch, an order that would guard the Oracle (DB) at the Temple of Cash-Flow and report every qualifying transaction to parquet files in AWS S3. The Data would then be pushed to cross The Event Bridge into The Cluster of Sparks and Storms.
This Witcher Who Writes is to ride the Elephant of Hadoop into The Cluster of Sparks an Storms, to weave the signs of Map and Reduce and with speed and precision transform The Data into The Insertion Plan.
However, how exactly is The Data to be transformed is not yet known.

Will the Witchers be able to build The Data's New Path? Will they figure out the mysterious transformation? Will they discover the Undocumented Java Tool's secrets on notifying customers and aggregating data?

This story is still afoot. Only the future will tell, and I will keep you posted.

Apparently Razer is rewarding its users with "Razer Silver" - currency for use ONLY on Razer Products - if you install their crypto miner ("Razer Softminer") and earn them money? ...what???

Thoughts? I think this is ridiculous. But I am also curious about it.

Hello DevRanters!

I've put together a gaming desktop, and I want your opinions 😊

This is the third part of my ongoing series "The Ballad of the Six Witchers and the Undocumented Java Tool".
In this part, we have the massive Battle of Sparks and Storms.

The first part is here: https://devrant.com/rants/5009817/...

The second part is here: https://devrant.com/rants/5054467/...

Over the last couple sprints and then some, The Witcher Who Writes and the Butchers of Jarfile had studied the decompiled guts of the Undocumented Java Beast and finally derived (most of) the process by which the data was transformed. They even built a model to replicate the results in small scale.
But when such process was presented to the Priests of Accounting at the Temple of Cash-Flow, chaos ensued.
This cannot be! - cried the priests - You must be wrong!
Wrong, the Witchers were not. In every single test case the Priests of Accounting threw at the Witchers, their model predicted perfectly what would be registered by the Undocumented Java Tool at the very end.
It was not the Witchers. The process was corrupted at its essence.

The Witchers reconvened at their fortress of Sprint. In the dark room of Standup, the leader of their order, wise beyond his years (and there were plenty of those), in a deep and solemn voice, there declared:
"Guys, we must not fuck this up." (actual quote)
For the leader of the witchers had just returned from a war council at the capitol of the province. There, heading a table boarding the Archpriest of Accounting, the Augur of Economics, the Marketing Spymaster and Admiral of the Fleet, was the Ciefoh Seat himself.
They had heard rumors about the Order of the Witchers' battles and operations. They wanted to know more.

It was quiet that night in the flat and cloudy plains of Cluster of Sparks and Storms. The Ciefoh Seat had ordered the thunder to stay silent, so that the forces of whole cluster would be available for the Witchers.
The cluster had solid ground for Hive and Parquet turf, and extended from the Connection River to farther than the horizon.
The Witcher Who Writes, seated high atop his war-elephant, looked at the massive battle formations behind.
The frontline were all war-elephants of Hadoop, their mahouts the Witchers themselves.
For the right flank, the Red Port of Redis had sent their best connectors - currency conversions would happen by the hundreds, instantly and always updated.
The left flank had the first and second army of Coroutine Jugglers, trained by the Witchers. Their swift catapults would be able to move data to and from the JIRA cities. No data point will be left behind.
At the center were thousands of Sparks mounting their RDD warhorses. Organized in formations designed by the Witchers and the Priestesses of Accounting, those armoured and strong units were native to this cloudy landscape. This was their home, and they were ready to defend it.
For the enemy could be seen in the horizon.

There were terabytes of data crossing the Stony Event Bridge. Hundreds of millions of datapoints, eager to flood the memory of every system and devour the processing time of every node on sight.
For the Ciefoh Seat, in his fury about the wrong calculations of the processes of the past, had ruled that the Witchers would not simply reshape the data from now on.
The Witchers were to process the entire historical ledger of transactions. And be done before the end of the month.

The metrics rumbled under the weight of terabytes of data crossing the Event Bridge. With fire in their eyes, the war-elephants in the frontline advanced.
Hundreds of data points would be impaled by their tusks and trampled by their feet, pressed into the parquet and hive grounds. But hundreds more would take their place. There were too many data points for the Hadoop war-elephants alone.
But the dawn will come.
When the night seemed darker, the Witchers heard a thunder, and the skies turned red. The Sparks were on the move.
Riding into the parquet and hive turf, impaling scores of data points with their long SIMD lances and chopping data off with their Scala swords, the Sparks burned through the enemy like fire.
The second line of the sparks would pick data off to be sent by the Coroutine Jugglers to JIRA. That would provoke even more data to cross the Event Bridge, but the third line of Sparks were ready for it - those data would be pierced by the rounds provided by the Red Port of Redis, and sent back to JIRA - for good.

They fought for six days and six nights, taking turns so that the battles would not stop. And then, silence. The day was won, all the data crushed into hive and parquet.

Short-lived was the relief. The Witchers knew that the enemy in combat is but a shadow of the troubles that approach. Politics and greed and grudge are all next in line. Are the Witchers heroes or marauders? The aftermath is to come, and I will keep you posted.

Are you willing to share details of your salary, or for contractors your daily/hourly rate? If you're not, that's interesting to know too.

Interesting to know;
- Currency (hopefully obviously)
- Location of work (or if remote, primary location of employer?)
- Contract type (FT/PT employee, contractor/freelancer)
- Job title (or general activity for contractors)
- Number of years in role/contracting
- Whether or not you would or have shared your salary with a co-worker (perhaps you're willing to share here but not with a co-worker)
- Gender

The 'Why is it soooo taboo to ask co-workers salary?' question made me think about this (https://devrant.com/rants/1557306/...)
