- It seems like every new program is written in Rust these days. In fact, many older programs are being rewritten in Rust, including a lot of the standard shell utilities. Today, I wanted to briefly mention seven Rust programs that I have installed that I think you should know about.

@@ultradude5410 yeah most of us know about homebrew or macports
bat works on windows :)
@@YoloMonstaaa Man bat is just amazing, i have to admit
@William Berry no it isn't
The biggest reason for ripgrip (rg) wasn't mentioned: speed. When it comes to recursive searches, rg absolutely destroys stock grep. It's way, way faster. It's also clever: that pretty output that it does to make it more human readable only occurs when it knows the output is the terminal. If you pipe the rg results to anything else, it knows that and switches to the more typical line-by-line response.
Same goes for bat when piping it to another program
How does it implement that differentiation? Does the stdout printing module have some option for that
As a professional programmer I can tell you, is not a meme, is just a really cool language that has a very innovative memory management that offers the safety of a garbage collected language, without the garbage collection or any overhead/bloat of runtime, because it uses a memory model of 'ownership' and borrowing with a powerful type system that C can only dream of.
Yeah RAII didn't exist before Rust. Of course C++ is the same as C. Of course it's not a meme, with all zealots telling to rewrite programs in Rust.
@@SbF6Hwell, actually rust memory system is not based on RAII
@@user-sn9dy5sq1q Yeah it is based around furry magic.
@@SbF6H No,, just on type system. Why so arrogant lol
@@user-sn9dy5sq1q What? Furry magic is omnipresent.
Bat really isnt a cat replacement it's more of a less/more replacement
True.
not true though, bat justs highlights syntax and adds line numbers, then sends its output to less
@@aedd3307 ok. But in practice the experience is the less command. So in reality it replaces less more than cat (at least by default idk if theres any flags)
can do the same with cat -n .zshrc | less
@@aedd3307 and that's exactly what a 'cat' replacement must not do. 'cat' comes from 'conCATenate'. The intended usage of 'cat' is to concatenate multiple files, as in '$ cat file1.txt file2.txt >> file1-2.txt'. Thus 'cat' must not mess with the input stream unless you explicitly tell it to do so. If you replace standard gnu utils the system relies on with tools behaving differently (like eg 'alias cat='bat') things will break.
Bat should have beed called "rat", because r is for rust
brat
Pin this comment already 😂😂
Ah but cat gets to eat rat. At least bat could get away
But bats are flying rats (check their faces in google image)
Thank god alias exists
You forget alacritty which is the terminal you are using in this video.
For Rust, people are switching to it,because it is a very replacement to C++ that has similar performance while handling memory in a better way and being memory safe
Yes, also.....broot. Another Rust program that I have talked about on video.
haha, exactly what I was commenting!

exa is available in the official Arch repos, not just the AUR.
You can just use cargo, installing it is realy easy, like easyer than npm in my opinion.
@@Muttisuri Of course you can, I just thought I'd mention it was in the official Arch repositories because DT said it was in the AUR.
@@Muttisuri yes you can use cargo but tbh using the package manager is better because updating the packages would be much easier as you dont have to keep doing cargo install --force every time theres a new update for exa
@@Muttisuri Why not just use an AUR helper like Paru?
@@raphtlw
I'm not 100% sure but doesn't cargo update the package if it finds a more recent version?
The major thing with ripgrep for me is the performance. You can ripgrep through big projects considerably faster than with grep.
Getting started on Rust:
Step 1: Gather some resources with your rock
Ily
Aye, I never made it far with my rock. Were good days playing it.
Vscode already uses rg for its workspace search feature IIRC. It's simply too much faster than grep to ignore
I struggle to keep up with all the new CLI tools in the ecosystem... so it's great to just watch a roundup video like this one. Thanks and looking forward to more roundups!
I am a Sr Software Engineer who does know Rust. Rust is a "immutability first" language. Often times the reasons vulnerabilities in code occur is due almost exclusively to mutable data in memory that's getting modified in real-time by other software trying to take advantage of the memory exploits. Rust makes mitigating this a first-class citizen. Which means, if immutability principles are followed, the amount of vulnerabilities will naturally fewer and, when they do occur, much less likely to have downstream effects, while being more easily maintained.
Rust as an amazing system-level language. It is a C-level language. Other languages based on Rust are coming down the line at some point. NodeJS linked-libraries are being written in Rust as well as Web Asslembly. Web Assembly is a compile target of Rust for web applications.
Rust has a TON to offer the software community.
immutable variables in rust only guarantee compile-time immutability. They can be modified if the program is hacked. On linux you need to mmap a memory region and use mprotect to prevent the data from being modified at runtime.
hey mr. Sr Software Engineer, could you explain how local variables in a function which are on the stack are immutable at the binary level?
@@apestogetherstrong341 I get what you meant but that *can* actually happen in both Rust, C, and other languages. It's called "const promotion". Basically, when the compiler recognizes that it's safe to perform the calculation at compile time and store the result in the compiled binary as an optimization even though you didn't use explicitly use `const`.
That said, Rust *does* help to give the compiler backend more freedom to do stuff like that by making stronger promises about how things will behave. (And, as such, it'd also be more amenable than C or C++ to automatic insertion of calls like mprotect.)
@@ssokolow well, const promotion can't happen with something like "let x = arg_1 + 2", in that case it's just incrementing the stack pointer and moving to it. But yeah, i get what you meant too
@@notuxnobux If you change a value of immutable variable via hacks or something on runtime you will probably introduce a UB in the program.
Even Microsoft is starting to rewrite Windows in Rust.

Excellent list. One more: delta -- a viewer for git and diff output - 🦀⚙️ - it is fantastic. Thanks for doing the video!
The best thing about ripgrep is, that it is insanely fast! Very useful for searching a string in a file recursively.
Dude, I absolutely love your channel. I've been an emacs user for seven years and switched to doom about a year ago before finding your channel. I always learn something useful from your channel and this vid is no exception.
You’d probably like the bat-extras repo. turns tools like ripgrep and man into batgrep and batman. so nice. also works well with diff-so-fancy.
I have been running bottom as a rust replacement for htop and it looks really nice with a lot of good info.
Very cool! Thank you. If you find more please do another video.
All I am waiting for now is a window manager written in Rust. Thats all we are missing
There is LeftWM
DT: "I am not a programmer."
Also DT: *starts programming in Haskell*
No doubt. I've been using exa and starship for a few months now. And now om deffinitly going to use the rest
Awesome tools! Thanks for sharing
Great video also with great comments by viewers. I've installed all of these on Raspberry Pi's and m1 Mac.
Go and Rust are popular modern systems programming languages for a reason. Built in build systems, package management, and testing suites lead to building robust fast reliable software very quickly. Just look at how fast the Pop!Os team can pump out really good systems level software with some of the best runtime safety in the game. Go routines provide a revolutionary way to implement concurrency. So many benefits behind these languages. They also lack all the "history" and backwards compatibility bloat issues that languages like C++ have. Referring to these languages as "memes" merely shows a drastic misunderstanding of what they accomplish.
Go is not for systems programming.
it's not just a "less"-feel for e. g. bat command (and I would assume probably the process listing one, too), it literally just pipes into "less".
AFAIR, the choice of pager is also configurable; might have some kind of environment variable.
I ve got an off topic question, as you are using the ergodox. There is something like the zsa moonlander have you ever heard of it if yes is it likely that you would give it a try if the one you currently got for example broke? Unfortunately there aren't many user videos and like reviews so that there would be more than just first impressions...
There are quite a decent number of reviews now. One guy even specializes in it. Just search for ergodox vs moonlander. A british guy did a fantastic review of both. There are some major differences, and I mean really significant to consider. I would tend to say moonlander si better, but ergodox also has ome points going for it. It depends what you want. I ordered my moonlander a week ago. Still 1 month to go till I receive it.
Major differences I found: moonlander is more compact; better for travel. The thumb area swivels, this is more ergonomic and also allows for adjustment for smaller/bigger hands. Thumb area has better key redesign. Moonlander has RGB on every single key; not so on ergodox. Lot of keys do not have RGB. RGB is thicker, more robust and also since thumb area does not pivot, it has 1 less point of breakage in the hinges. In fact the reviewer in the youtube video I mentioned - his hinge on the thumb pad broke. Could have been a defect though. Moonlander uses type c cable (not that big deal though). Exterior row on each side has keys that are less wide on the moonlander, bringing the center point where you press closer to your finger, which could be important. These are some major highlights. Cost is the same. It was here, on DT video I learned of the ergodox and subsequently bought the moonlander! Super excited.
the standard find command also has an --exec to run additional commands with the find results.
I really hate when command line tools have no man page.
Ripgrep has one. You just have to use rg instead of ripgrep
@@Ricojo777 I was talking in general actually, this video just reminded me. But thanks for letting me know! :D
I always thought man pages could be a whole lot better. include the top 10 useage examples for one idea
@@randaldavis8976 It depends on the man page. For example, Linux programmer's manual have some nice usage examples.
Anyway, I think you might make use of `tldr` command
@@randaldavis8976 pipe it through bat. It improves it :). Then in fish, make the bat an abbr for man, and there you go, it will always do this for you no extra typing
I have all of them installed! And use it often!
Hey dt! Could you take a look at the ion shell?
Hey DT, I would like to see a REDUX OS review of Yours about that linux distro since we are watching RUST things now, would be very interesting.
Thank you so much. It is really so handy programs.
Hey DT, what's the best AUR helper?? Is it yay, because it's 3 letters?? Or is there more to it??
Tokei actually also recognizes embeded languages. So if you have javascript in your html it shows that as separate.

I believe ripgrep already covers most of the use cases of fd with "rg --files".. I often pipe that to "rg [string]" to find files
Also check out bottom: a bashtop like replacement for top.
The reason your .bashrc didn't show up in fd is because fd ignores hidden files by default.
Also fun fact - bat uses less under the hood (and i'll guess that procs does as well)
extra fun fact: you can add the -u flag up to three times to make fd ignore less and less files. if I *really* wanna make sure, I run fd -uuu
Cool. But are these more efficient in relation to the added features or just more colorful?
I can't say about all of them, but ripgrep is specifically designed to be faster than all competitors (there's a whole blog post linked from the README going into great detail on it) and, while piping things through pygmentize is known to be a bit sluggish, bat uses a syntax highlighting library named syntect that's specifically designed to be lightning fast.
Can you do a video on wtftw, a wm written in rust.
bat vs cat - is If "bat file | grep 22" will get lines with 22 or line 22 too? How much slower is it?
same question with all of them - old gnu utils can be chained - can these? Will they break old scripts?
bat is designed to turn off all its fancy features and behave just like cat if you feed it into a shell pipeline.
DT showing rust programs in a terminal made in rust.
Alacrity is written in rust if remember well
In a rusty computer, and that'd be perfectly rusted.
thank's this was very good
Great stuff. I always seem to get something good from every video. I don't have a linux machine right now, but I have been putting all of this knowledge to use in my WSL/openSUSE setup. Granted, not everything wants to run on Wayland, but most things do it just fine.
A quick edit of my alias list and I can now see folders and files by color and sorted. Before, I couldn't tell a folder from a file. Awesome.
For FD, I set an alias for "find" to search where I am and I set "search" to search from the / directory. Sweet.
Bat just looks like nvim -R or Vim but with less functionality. Which you could easily alias to "nvR", "nvr", "vir" or "viR" inside your bashrc file.
A year and a half has passed since this vid posted.Amazing stuff going on in Rust.Pkg's,like alacritty DT did showed us what cpu accelleration accomplishes.Rust doesn't do null reference (Tony Hoare conjured that up in 1965.Stated in public forum 2009 that null reference was $billion mistake.)Valid Rust doesn't,anyways but one can try unsafe Rust to get through compilation.Hazard pointers need to be dealt with correctly,though,or panic/crash at run time.Rust doesn't do garbage collection. 100% thread safety.Suscinct error handling.Zero cost abstractions.Rust compiler expects all but absolute perfection or no compilation.Even details minor 'errors' at run time,if any. ie #[error(unused-variable)] concider using '_' .The detail in Rust compiler info is something else.
Even most experienced computer science phd's get stumped here and there in Rust.This language is a whole new ball game even though it's C++11 and C++20 at core.
Alien/Greek to those familiar with earlier computer languages.Cat's out of the bag now and those who bawked before now realize they better get on board or get left behind.Rust stuff coming faster than tutorial vid producers can deep dive into it. async/await concurrency is revolutionary.It looks like Rust is going to blow the lid off everything ever written code before.
You should check out nushell. It's a shell written in Rust. It's now at minimum viable product status.
I doubt you'll use it as your main shell any time soon, but you may find the general concept to be interesting. Like fish it isn't aiming to be POSIX compliant, but is instead trying to evolve the shell as we know it.
He did
@@JosueRodriguez08 It's been a year since then. Probably worth another look.
@@IcarianHeights Right now? Probably. Long term, who knows. That said, nushell isn't trying to be a PS clone, it's just borrowing some of PS's concepts along with others (such as the functional programming paradigm).
I'm thinking of rewriting efitools in rust. As the don't compile from upstream. Missing a little financing for that yet though
The other current programming language of serious consideration is Julia. Do you know any Linux programs in Julia?
How can I get a header art like yours? I love the random art at the beginning of the terminal.
Nvm I found it czcams.com/video/U6e05Y3DC5E/video.html

Thank you for bat
Fractal is a GTK Matrix client written in rust
Congrats for these Rust pearls. Now...waiting for the part II of these Rust pearls...or the review of Redox, the OS written in Rust.
wont alias to legacy command names break bash and other scripts since the output and flags differ?
best thing is to use abbr (abbreviations) - something fish has. It is like alias, but before execution, fish replaces your alias on the CLI with the actual content of the abbr. So even in history scrolling, you see the actual command. It is ingenious!
Can you please tell me how to get suggestions in terminal while typing? Thanks
that comes with the shell he uses - called 'fish'. Install it and you will get autocompletion support. It is awesome
I would probably start using these all right away, but much of the work I do is on company servers into which I cannot install what ever I fancy :/
So I think that except for Alacritty and Fish shell, I have to stick with the old ones for now so I don't remember which commands are available on which computers...
Thanks for the list though, it is nice to see that more and more Rust programs like `bottom` to replace `htop` are coming!
Often, it's preferable to stick with commands that are standard/default to most machines. Getting efficient/proficient with those "standard" commands offers much higher "return on investment" because that skill is more "portable". So while all these tools are cool, it's not cool enough for me to invest on them and abandon the more widely available standard commands.
I tend to agree with sticking with the POSIX standard tools but would point out that these rust tools are statically compiled binaries that you can copy around via scp/ssh and run them arbitrarily without even needing to install them into a standard $PATH.
Cant imagine doing this for a prog written in python or node/typescript however.
Huh, I’ve thought you were a programmer since I started watching the channel. Do you do youtube full time? Or do you have a day job?
Dt used to do retail full time and youtube as a hobby but now he does exclusively youtube. He has also never been a programmer by trade he's said it a lot.
I liked most of this programs but I'm not switching to most of them because if you run for example cat the file stays in the terminal but with bat when I quit it isn't above(it don't stay in terminal) same with Procs
bat uses your $PAGER (less by default) to display its contents when in an interactive shell. This can be bypassed with the -P option, or configured to use a different one, or none.
@@davidh.4944 Thanks! Now I can switch to it.
Even Pop!_OS is making their own DE in Rust!
Not a programmer by trade, but until now, I come to love every Rust program I ever used. Fast, efficient, easy to use. _fd_ is such a breeze compared to the standard _find_ command. _exa_ has won my _ls_ alias.

there is *git-delta* which is a better diff, you can configure it with git and then see the diff in color, custom color schemes, and even side by side diff, with numbered lines on each side. It goes great with *bat*.
Does bat actually function like the cat command? That is dies it concatenate two files without the extended cimmands for color and line numbers? Remenber cat is made to be in a string of commands.
I just tested it. Yes, it can concatenate. Though, if you want strictly like how cat functions , just add the '--plain' flag.
@@whaaaaaaaaaaaaaaaaaaaaaaaaaat Well, that's cool.
@@kellingc To quote the README, "Whenever bat detects a non-interactive terminal (i.e. when you pipe into another process or into a file), bat will act as a drop-in replacement for cat and fall back to printing the plain file contents"... though you can still use things like "--color=always" to override that.
the difference is that
C is a programming language with
the most basic features from the 1960s
these features allow you describe low level stuff
C is basically a template language for good programming patterns in ASM
but this comes without safety and is prone to produce all sorts of damage like segfaults
Rust is a programming language with
sophisticated features from different languages
including Programming Language Theory (research)
including the experience of the last 30 years in the industry and lessons learned in C++
also allows you to describe low level stuff
its memory model protects you from segfaults without producing any runtime dependency (due to that ivory tower research that hackers tend to despise)
basically C is garage amateur carpentry while Rust is space tech engineering.
i want to create my own distro, create my own command, my own planet, my own universe, my own species and my own dna
colorls is a ruby port of ls. I think colorls is better then exa because it has all of exa color stuff but it has file icons and has the date of the file that changes in tint based off date
Maybe lsd? (lib.rs/crates/lsd) I wouldn't want to have to wait for an ls replacement to wait for Ruby or Python or whatever else to seek around, gathering its files, if I'm still on an SSD-less machine and they're not already in the disk cache.
But cat doenst have these lines, because its often used in script, so bat is more a replacement for less
Same for ripgrep. So using it as a alias should not be done
Can you disable these visual extras with a flag?
It's done automatically when not outputted to an interactive terminal
Think it's the fact that it has manual memory management and it's not very verbose. People love it and it's pretty swift.
Sorry, but judging by the output of bat, it's not a replacement of cat, but for something like less or more.
Because when using cat, you only expect the file content to show up on stdout. That's necessary for piping as well.
This is my thought as well. Bat is nice but not a replacement for sure.
@@koderkev42 bat checks for the output method first, that formatting only happens in terminal, not piping; read the man.
Bottom is a nice one too
Hey DT. You do know that Rust comes from Mozilla Research. I repeat: Mozilla ;-)
Assuming you aren't trolling here there's a clear difference between Rust, a programming language and Firefox, Thunderbird, etc which are internet programs.
Rust is a programming language, it is harder to censor and almost conpletely pointless to do so anyways because of the abundance of other programming languages which aren't censored.
Mozilla's other software like their browser and their email client are much easier to censor and there is a motivation to do so.
@@hostgrady It's called a joke ;-)
@@gotchaxp so you were trolling? Ok well thats good
Rust isn't part of Mozzila anymore. They are their own faundation now.
The linux kernel and most of the linux programs used to be written in C which is a very old language and even for those with experience it can be hard to write code in C, rust is a new programming language which can replace C because it's also low level, so it's very fast (not faster than C but close) and it has some features that make it easier to code in.
Recent benchmarks have shown that Rust can be faster than C. However, I don't think of Rust as a C replacement but an addition to systems programming. There will always be scenarios where it'll be preferable to use C/C++ in systems programming. Rust allows you to write low level code in a precise, short and abstract way - that is brilliant. But it also has very strict rules and sometimes doesn't let you do "your way of programming". Nevertheless, I do most of my programming in Rust. I just don't think of it as a replacement
@@lieywe3438 How can it be faster than C? Is it a compiler issue (poor optimisations by C compilers), or is it the langage itself? It seems to me that C is closer to machine code than Rust. So I don't get how Rust could be faster.
@@brinckau Rust, as a abstract language, has more optimization opportunities than C, the abstract language. It is about language semantics.
And C is not more close to the hardware than Rust, they are same.
@@ekremdincel1505 Assembly is not an abstract language, is converted to machine code without any optimization, and yet cannot be beaten in terms of speed (because in the end, everything is machine code, so writing machine code directly, or assembly code, makes it possible to do exactly the same as a C or Rust program would do). Provided you're good enough to write excellent code, of course.
So I'm not convinced by your argument about optimization opportunities.
I also believe that C is closer to machine code than Rust, because Rust has more abstractions than C. Otherwise, Rust would not have more optimization opportunities than C.
@@brinckau Every language is abstract. I mean the formal definition of the language regardless of current implementations.
I didn't even say anything about assembly in my previous post.
You can write inline assembly in Rust.
Rust's abstractions are zero cost. And having useful abstractions not necessarily prevents you from having tools for writing low level code in your language. Rust have both safe references and unsafe raw pointers, for example.
"So I'm not convinced by your argument about optimization opportunities."
An example about language semantics:
Rust inserts C's equivalent of "restrict" keyword everywhere, thanks to it's borrow checker, and this gives the more optimization opportunities. People use the "restrict" keyword in C so rarely. Not everything is theoretical.
> I don't see why anyone wouldn't just replace `cat`
Because it works just fine, and you really shouldn't be using it for reading files at the terminal (use `less`).
Rust's advantage over C is its memory safety. `cat` is already memory safe. Thus as a user, there is no advantage to me switching.
Hey dt, did you know of "yi: The Haskell-Scriptable Editor" ? It would be awsome if you made a video about it
Rust language would be my top choice for a programming language to be stranded on a desert island with a laptop and solar powered battery recharger - if could have only one language choice. It's intrinsically versatile enough to be applied to about any programming domain - with Web Assembly support, could even be used to write programs that run in the browser. And presumably being stranded on said island, would have plenty of time to master its borrow checker and annotations - and the cool kids stuff like pattern matching and other functional programming features. And finally get around to learning how to write macros in its powerful macro sub-language.
haha it's COVID time, we're all stuck on an island...your wish came true...get cracking....as for me, I live offgrid in the mountains in Canada, so, pretty much the scenario you already describe....

I haven't programmed anything serious on Rust, but as far as I have seen about the language, it seems to be a modern and better version of C++, I have programmed on C++ since before C++11 was a thing and by today's standard C++ has became a very bizarre language.
For example on C++ is a best practice to mark every variable as «const» or «constexpr» unless you need it to change while on Rust variables are «const» by default and you only need to mark them as «mut» when you need it.
Some people have said that “Rust is not as efficient as C++” by comparing the ASM output of same codes, but that is not true, the compiler might not be as efficient, but IMHO the language is as efficient as C++.
For which code Rust outputs worse ASM then C++?

Hi mate. time stampts might be useful in this video :)
People love rust because it can be written at a pretty high level but without the disadvantages of other similar languages like go because it's not a garbage-collected making it wicked fast.
As a Rust lover and enthusiast, I'm very pleased to see this video on your channel)
Ignoring the discussion c/c++ vs rust, the problem I have with these rewrites is that they often change the default behavior and interface. There most probably is a reason why tools behave the way they do, even if you as a user don't understand or know it. cat, ls, find, ... are all POSIX standard utilities the system and a lot of software relies on that you simply cannot mess with. You want to reimplement gnu or standard utils? Fine, but retain default behavior and the interface. Otherwise, do not advertise them as replacements, bc they are not. They are alternatives, but not replacements.
@@bigpod replacements have exactly the same behavior and are completely interchangeable. Not the case with most of these rewrites. It's like changing APIs or interfaces. If they do not behave exactly the same, they are not interchangeable and thus not replacements. Also you should care about standards like POSIX because they guarantee interoperability and portability. But then again, if people do not understand the crucial importance of stable APIs and interfaces, and why there have to be reliant contracts for IPC, then they shouldn't program essential tools or services in the first place. Changing well-known, reliant and expected behavior, just for the sake of being different and promoting one self's ego (I know better, I do it my way), will break systems and make maintaining interoperability between processes a nightmare.
@@bigpod try the following then:
$ sudo cp -f ~/.cargo/bin/bat $(command -v cat)
$ sudo mkinitcpio # on arch, or update-initramfs on debian, check your distro
$ sudo reboot
With my understanding of replacement, this should work flawlessly, but then again, my understanding could quite possibly be flawed. Chances are, your system won't even boot anymore, because 'cat' is an essential binary used in the initial ramdisk to boot practically all unixoid OSes, which is possible thanks to standardization like POSIX. But since you do not care about standards, interoperability and portability, having to repair constantly breaking and non-functioning systems is probably not a problem for you anyways.
@@onehaxxor8574 bat works exactly like cat when not in interactive terminal output, check before talking ?
If someone ever rewrites emacs in rust, hopefully they will take the best parts of emacs & the best parts of vim and combine them.
procs seems pretty handy. I will check that out.
bat seems like more of a less replacement than a cat replacement, unless it behaves differently in scripting contexts. The thing I want out of any cat program is 1) it outputs all the characters from a file in order, and 2) it concatenates the things I give it. The formatting makes it kinda useless as a cat replacement.
It behaves differently in scripting/piping. you should check it's docs, they have some nice options.
Cat is one of the few things in GNU Coreutils that doesn’t have any colorization in its output. Even ls is starting to use colorization by default in most cases. Disabling the colorization is pretty easy. There are a few fairly standard ways of testing if a file descriptor is connected to a terminal.
Very cool vid Derek...thanks again. I've heard of RUST...and like you am not a programmer. But I'm gonna be checking this stuff out. Cheers!
DT you amaze me..... you are very good at this.... I am learning at such a high pace because of this...... if you enjoy doing this channel please keep going😎
nice apps loved it
