Map, Filter and reduce explained!

Well okay..

Loved the first project at the university. Your game had to load a map from txt file and create a labirynth with a player inside. It shoud include a bird's eye view and FPS-like - all using only console characters. There were some bonus points - for example for animation or built-in map editor. (language was C)

So I'm working on a live map of my school's bus system, and I needed some filler images to test out how the stops were being drawn on each route...and honestly wish I could push this version to production

A programmer is walking along a beach and finds a lamp. He rubs the lamp, and a genie appears. “I am the most powerful genie in the world. I can grant you any wish, but only one wish.”

The programmer pulls out a map, points to it and says, “I’d want peace in the Middle East.”

The genie responds, “Gee, I don’t know. Those people have been fighting for millenia. I can do just about anything, but this is likely beyond my limits.”

The programmer then says, “Well, I am a programmer, and my programs have lots of users. Please make all my users satisfied with my software and let them ask for sensible changes.”

At which point the genie responds, “Um, let me see that map again.”

Bill gates found a bottle in his garden.
He decided to rub it thrice (whyever) and a geany surged.

Bill gates: h.. He.. Hello?
Geany : hi, im willing to give you one wish as you saved me
Bill gates: I WANT WORLD PEACE, HERE IS THE MAP WITH ALL THE WARS ON THE WORLD!!
Geany: thats impossible. Other wishes?
Bill gates: fix every bug in windows vista!
Geany: gimme that world map

That's why I never believe common sense when I write Javascript.

My non-dev boyfriend installed Python via the command line and ran a server to render a map of Pokémon in his neighborhood. I don't know whether to be impressed or scared 😂

My map generator(rewritten in swift) produced its finest continent... after 40 minutes...

The great linux world map

JS map, filter, reduce...

Found a Google employee in street view getting lost and using paper map .. There are also seem to be 2 guides with him...

I find it kinda amusing

A programmer was walking along the beach when he found a lamp. Upon rubbing the lamp a genie appeared who stated "I am the most powerful genie in the world. I can grant you any wish you want, but only one wish."

The programmer pulled out a map of the Mediterranean area and said "I'd like there to be a just and last peace among the people in the middle east."

The genie responded, "Gee, I don't know. Those people have been fighting since the beginning of time. I can do just about anything, but this is beyond my limits."

The programmer then said, "Well, I am a programmer and my programs have a lot of users. Please make all the users satisfied with my programs, and let them ask sensible changes"

Genie: "Uh, let me see that map again."

"Why can't I just get the terminology right in my head"

java: map.
javascript: object?
python: dictionary!
ruby: HASH!
php: aSsoCiaTiVe aRrAy

Today a friend tried to zoom in on a paper map that I had put on the table...

Now that I have time to approach my ultimate dream ( being the pro penrester ) , asked a hacker for a road map and he gave me (U'll rarely see such open hackers that share knowledge :) )
Surprisingly I've been familiar with all the topics but being the most pro , requires u to be pro in every single topic .

Guess what ? I'm starting from basic linux commands all over again 😂
echo 'hello world :/'

Just spoke with another teams developer. (She's using Java)

Her: so we get a json object from your service, I want an array
Me: well that's not what you said in the specs... And it's not hard since it's just a Map
Her: what Map? It's JSonObject I need an Array
Me: give me the library your using..
Her: here...

I Google the documentation and methods and paste the link and the methods to use:

-length (she also wanted count)
-toJsonArray

This ain't JS, just use the . operator and go thru all the methods' docs... Or learn to use Google

When u did too much geocoding and map stuff. People ask me where u live, i be like I live at lat 43.8 lng -79.3. Find me homie, let's chill

beginner coder: figures out how to write a feature

average coder: knows a few different ways to write a feature. but not quite sure on which one to use.

master coder: meditates before starting a project. closes his eyes to map out the entire infrastructure of the project.

god coder: gets paid ALOT of money to guide people on the right to do it.

Front end engineer road map for 2018

We have a Miro collaborative whiteboard where product managers map functionality and user flows.

When client compares his cheap 3 months old project App with well established multi Billion $ Bigwigs' Apps :|

"Look how cars are moving smoothly on map in UBER, I want something like that"

"Look how fast is GOOGLE Search"

"Look how AMAZON figures out what we want next"

Are you fuckin serious :|

Map/Filter/Reduce

Continued from pervious Rant.

The Drone sends out a signal to the Headquarters. A "Rare Entity Found" alert shows up on the screen. "Quick, load the map", says the General. Map shows the current location of the Drone. "Dispatch the Team", signals the General while his forehead show signs of tension.

Further down the room, a man quickly types on his phone and hides it.

Far from all this, in a quite city where the street lights have faded away. Old buildings which look like they are about to fall and crumble. The sound of wind can be heard for miles as there is silence all around. A light from one of building's room is turned on and quickly turned off. A man, checks his phone in sleep. Awakens and pours a glass of water to drink. Quenching his thirst, he opens his laptop. Laptop's light is the only light illuminating his room. He again gives a second look at his phone. The message is still there.
"It has been found"

Porting over code to python3 from python2 be like:
(Cakechat, in this case)

Day 0 of n of python 3 compatibility work:
This should be _easy_, just use six and do magic!

Day 1 of n:
Oh, true division is default instead of integer division, so I need to replace `/` with `//` in a few places.

Day 2 of n:
Oh, map in python2 behaves differently than map in python3, one returns a list, other an iterator. Time to replace it with `list(map())` then.

Day 3 of n:
Argh, lambdas don't evaluate automatically, time to fix that too.

Day 4 of n:
Why did I bother trying to port this code in the first place? It's been so long and I DON'T EVEN KNOW WHAT IS BROKEN BECAUSE THE STUFF RUNS WHEN I BREAKPOINT AND STEP THROUGH BUT NOT WHEN I RUN IT DIRECTLY?!

Day ??? of n:
[predicted]
*gives up*
I've had enough.

Once, when working on top down RPG, I woke up at 3am and wrote map moving system. It worked flawlessly. Later had to spend 2 days to understand how the fuck it actually worked.

Ahh nights so full of passion.

I was asked to map a mathematical problem to an algorithm for first round of interview. I did it in 5 lines with O(n) and it worked. was told that was not the correct answer sent me an answer with O(n^2) and about 40 lines. in anger, I sent a five page mathematical proof along with analysis why mine was better. surprisingly, they took me in for second round. tanked it because I continually stuttered and froze. I was able to answer it once I got home. decided against sending it.

chaosbot/chaos github repo looks like a London underground map.

Also, if you haven't seen this yet, it is a new project where code is updated by the community democratically.

Go give it a devrant hug of death.

It happened just now.

Yes, I put "there is no need to be upset 10 hours" on governmental terminal.

#hackerman

How? Well, I discovered that it was web ui, so random menu category -> random external governmental website with Google map on it -> you know the rest.

Large mousepad with world map. Not a toy or art but I like looking at it

I startet at this company where they made a map where some locations where displayed on a map. It took like 30 seconds to load the locations - and it could only display ten at once. To cover this fact they made it impossable to zoom out...
I circumenvented their incredably bad orm and queried the DB directly, created some indices, and only shipped coordinates, type and label (whereas they shipped the whole datasets to the browser before) - and suddenly i could show all 30k
pins at once in microseconds having less traffic then before. That was quite a leap.

Needless to say the app never reached nearly production, I left the shit show soon after and the ceo is dead by now.

boss: we should map all the possible ways to do things in the system so we can test them and make sure we fix the bugs.

Me: yeah, well, that is exactly what automated tests are for, every time we find a non-mapped way that breaks this we make a test out of it and fix, this ways we end up mapping the majority of ways.

Boss: yeah,yeah ... Let's sit down latter and map everything on a document.

I bet my ass we are never gonna have tests as a part of our workflow.

Last week our department drama queen was showing off Visual Studio’s ability to create a visual code map.
He focused on one “ball of mud”, vilifying the number of references, naming, etc and bragging he’s been cleaning up the code. Typical “Oooohhh…this code is such a mess…good thing I’m fixing it all..” nonsense. Drama queen forgot I wrote that ‘ball of mud’

Me: “So, what exactly are you changing?”
DK: “Everything. It’s a mess”
Me: “OK, are any of the references changing? What exactly is the improvement?”
DK: “There are methods that accept Lists. They should take IEnumerables.”
Me: “How is that an improvement?”
<in a somewhat condescending tone>
DK: “Uh…testability. Took me almost two weeks to make all the changes. It was a lot of work, but now the code is at least readable now.”
Me: “Did you write any tests?”
DK: “Um…no…I have no idea what uses these projects.”
Me: “Yes you do, you showed me map.”
DK: “Yes, but I don’t know how they are being used. All the map shows are the dependencies.”
Me: “Do you know where the changes are being deployed?”
DK: “I suppose the support team knows. Not really our problem.”
Me: “You’re kinda right. It’s not anyone’s problem.”
DK: “Wha…huh…what do you mean?”
Me: “That code has been depreciated ever since the business process changed over 4 years ago.”
DK: “Nooo…are you sure? The references were everywhere.”
Me: “Not according to your map. Looks like just one solution. It can be deleted, let me do that real quick”
<I delete the solution+code from source control>
Me: “Man, sorry you wasted all that time.”

I could tell he was kinda’ pissed and I wasn’t really sorry. :)

Just to clarify thing, FaceID isn't the same tech as what we've had on Android.

In Android, it's based on image recognition. That's the reason it was so easy to bypass with a high resolution photograph.

In FaceID, it projects thousands of dots on your face and creates a depth inclusive map which is used for verification. That's the reason why it's supposed to work even if you have glasses on, etc

So please let's stop with the comparison

Same days you just need a duck.

Me: map.get(record.Id)

Code: null

Me: no, map.get(record.id)

Code: null

Me: let's grab this record from the map

Code: null

Me: what the flying fuck, take this fucking ID from this fucking RECORD and find it in THIS god forsaken map.

Code: null

Me:.......

Code: 😉

Duck: did it occur to you the ID exists only AFTER the map is created.

Me: you fucking wha..... oh I'm a dick head.

#1 GoogleMap map = null;
#2 map.clear();

I'm used to bad code, since i'm responsible for code review of acadamic projects. But when i saw that one and last year students saying they dont know the reason, i died a bit inside

I worked once in a company which had this tourist app which should show places on map of the city. Unfortunately it slowed the App down to load more then a couple of places. Their solution was to limit the number of loaded places to teb and prohibited zomming out. I made it handle thousands of places at the same time. Main reason for the Performance issue was, that they sent all data they had about places big, big json objects with large text blobs) to the frontend. This part was easy, I instead sent only the data needed for the map like coordinates and icon type obviously. But still the backend struggeled hard with many objects from the DB, because they built a really shitty orm or what ever this was supposed to be: every line of data retrieved from the DB was immideatly wrapped in some class wich direved from another class which had some magic methods in it which caused some absurd loops over all other obejcts and even more DB queries in unexpected moments and also in the fucking constructor. So it turrned out that the map issue was only the top of the iceberg, since using any data from the DB was extremely expensive. The hard part was to understand the insaness of this abnormination and find the bottlenecks.

If you're using snapchat you might want to go on it immediately and change your privacy settings.
New update came out, they added a map with everybody's locations down to a couple of meters in accuracy... And the feature is on by default for EVERYONE to see, not just your friends.

What the actual fuck were they thinking?? Just think of all the ways this can go wrong.

The moment when you see "block chain" on a client's road map, but they can't tell you what that is or what they want to use it for

This is for visual learners 👌

Map that shows you how far you can travel within a certain time.

Client : Use google map because it has more data but make sure the location and navigation in the app as to look like Apple Map.
Me : 😧😧

You know a project's gonna be a pain in the ass if one of the file's the mini map looks like this. But wait there's more, this mini map is just a quarter of the whole file. Fuck

Any thoughts on whether my alternative keyboard layout will lower my risk for wrist pain? I map each key to an Amazon dash button on each edge of a large bookshelf in my office. It's lots of exercise, and I'm almost back up to my old typing speed.

My favorite game just released a 3D map of their universe.

That's fucking awesome! How much work this had to be.... OwO

First personal project in my new employment.

This is the situation:

[ • ] Frontend
Drupal with custom module which load an Angular 6 application inside certain urls. Da hell for my eyes but interesting in somewhat.

[ • ] Back end
SharePoint "database" middled by a my-boss-written Java layer used to map SharePoint tokens in something more usable

when you try to protect your privacy by using Brave browser but also want to use Google map ==...

The joys of mapping...
I'm playing around with some cartographer parameters and this happened. Thought it fits the christmas theme and was kindas beautiful so decided to share.
It's a map snowflake :3

Trying to hire more good devs... it's surprisingly hard. Guy with supposed decade of JavaScript experience fails code test, "I don't really use map function so I don't know it."

R U kidding me

...and yet my "maybe we should consider remote devs" idea isn't getting any traction :/

Did a few world map generations with the openmaptiles self generation tools and all went well.

Then, suddenly, no matter what system I use, it crashes with a Go error (I don't know much about Go).

Nothing changed in the repo and nothing changed in the OS.

Fucking hell.

A dev posts a link to his website on a dev group I admin, first thing said site does is ask for my location. I look, no map not logically apparent reason for it, so I close the site.

Ask they guy why he is asking for such private info and he responds to tell me that he does not think a person's exact location is that private, and if he really wanted it he would just use the IP address.

Like how many fucking levels of dense is that.

I will never stop being impressed by how detailed this scene in The Matrix Reloaded was.

Trinity is trying to hack into the terminal and shut down the power grid.

nmap (network map) is a linux tool for network discovery.

It is absolutely believable that in a post apocalyptic future where computers rule the earth, the entire power grid would be on a network that you can scan for like this and shut down.

Its a such a minor detail, but I'm really happy that the writers consulted with actual programmers.

Tasked to create a product road map.

Beg for feedback.

Get no feedback.

Present product roadmap to key stake holders.

Bitching, nothing but bitching.

Guess the developer did not expect this to happen.

Currently over at OpenStreetMaps.org (I requested a map for download)

Maybe it's not exactly about programming, but sure damned it caused it.
Back in the day I managed to create a warcraft 3 map which played tetris. The orc peons ran down with faster and faster speeds, since it was a multiplayer, we used to play it with friends. We played it so much during the day, that all of the dreams were about orcs running and exploding once you finished your line. It was the only dream I remember having.

The devRant July 13 update and roadmap is amazing. Great recap of recent happenings and the map to an exciting future.
I am proud to to be part of this wonderful community.
devRant rules!

Why the fuck do managers think beacuse a component has been build by another developer a shit ton of time ago, we can still reuse that fucking code.

For fucks sake, I had to rebuild a whole fucking map component that needed contextual filter and the fuckers just add extra functionality without consulting me. And gave me a tight schedule bc the customer, who btw disappeared for 6 months, will be mad for wasting his precious fucking time.

Fuck these clients.

One of my android project finally compiled with no errors!!
Happiness increased when it didn't crash👻👻👻
Finally some relief 😊😊😊

Hmmm, this feature that I added seems to make the whole process 50% longer. I need to optimize something. Let's see now...
Yeah, make that a shared resource and parallelize IO to leverage the multi-core architecture. Hash map for this, binary tree for that. This thing that gets called a million times can be written easily without a regexp. That thing can be rewritten in Rust as it's too demanding.

There! Works! And it's also a lot cleaner. Nice!

How's the performance doing? 70% longer.

That moment when a client is all upset about a tiny bit of cutoff of some text, but they haven't noticed they've been missing labels from their map for who knows how long...

I knew I was destined for programming when I was 11 or so, and I would spend my days after school until bedtime building levels with the Doom map builder. Shortly after that I begged my parents for a C++ for dummies book. Never looked back.

In the office I had the dashboard with coronachan stats and the map on the huge tv but the HR told me to stop that 😭

When the project your working on #GitUp map looks like an advanced level of guitar hero

Was creating an interactive map through Google Maps API. The map wasn't displaying at all on the website. Spent 2 hours trying to fix. Just realized I've not given height to the map div :-/

Highschool teacher tells us to work on a little text game, gives us 2 weeks. I wrote about 1600 lines of code with enemys, random map, fighting system,... And generally blowing everything out of proportion as always, because I'm so bored

Rant other than other rants this week

Errors be like "Source.ts 44:38", Source.ts has 28 lines. Alrighty.

Computer engineering : Insanity!!!

Today a friend of mine was assigned to make a Client-Server Encryption using Sockets. The guy did a great job applying BlowFish algorithm, but the teacher was disappointed because she couldnt map letters to the encrypted text and she declared the program to be wrong!!!

when you are asked a yes/no question but your input doesn't really matter...

I just managed to configure a second keyboard to map its keys to separate keycodes. Basically, I should be able to use it as a complete macro deck 😏 Thank god for Linux

Want to relax.......
its just a road map to success

Everyone and their dog is making a game, so why can't I?
1. open world (check)

2. taking inspiration from metro and fallout (check)

3. on a map roughly the size of the u.s. (check)

So I thought what I'd do is pretend to be one of those deaf mutes. While also pretending to be a programmer. Sometimes you make believe
so hard that it comes true apparently.

For the main map I thought I'd automate laying down the base map before hand tweaking it. It's been a bit of a slog. Roughly 1 pixel per mile. (okay, 1973 by 1067). The u.s. is 3.1 million miles, this would work out to 2.1 million miles instead. Eh.

Wrote the script to filter out all the ocean pixels, based on the elevation map, and output the difference. Still had to edit around the shoreline but it sped things up a lot. Just attached the elevation map, because the actual one is an ugly cluster of death magenta to represent the ocean.

Consequence of filtering is, the shoreline is messy and not entirely representative of the u.s.

The preprocessing step also added a lot of in-land 'lakes' that don't exist in some areas, like death valley. Already expected that.

But the plus side is I now have map layers for both elevation and ecology biomes. Aligning them close enough so that the heightmap wasn't displaced, and didn't cut off the shoreline in the ecology layer (at export), was a royal pain, and as super finicky. But thankfully thats done.

Next step is to go through the ecology map, copy each key color, and write down the biome id, courtesy of the 2017 ecoregions project.

From there, I write down the primary landscape features (water, plants, trees, terrain roughness, etc), anything easy to convey.
Main thing I'm interested in is tree types, because those, as tiles, convey a lot more information about the hex terrain than anything else.

Once the biomes are marked, and the tree types are written, the next step is to assign a tile to each tree type, and each density level of mountains (flat, hills, mountains, snowcapped peaks, etc).
The reference ids, colors, and numbers on the map will simplify the process.

After that, I'll write an exporter with python, and dump to csv or another format.

Next steps are laying out the instances in the level editor, that'll act as the tiles in question.
Theres a few naive approaches:

Spawn all the relevant instances at startup, and load the corresponding tiles.

Or setup chunks of instances, enough to cover the camera, and a buffer surrounding the camera. As the camera moves, reconfigure the instances to match the streamed in tile data.

Instances here make sense, because if theres any simulation going on (and I'd like there to be), they can detect in event code, when they are in the invisible buffer around the camera but not yet visible, and be activated by the camera, or deactive themselves after leaving the camera and buffer's area.

The alternative is to let a global controller stream the data in, as a series of tile IDs, corresponding to the various tile sprites, and code global interaction like tile picking into a single event, which seems unwieldy and not at all manageable. I can see it turning into a giant switch case already.

So instances it is.

Actually, if I do 16^2 pixel chunks, it only works out to 124x68 chunks in all. A few thousand, mostly inactive chunks is pretty trivial, and simplifies spawning and serializing/deserializing.

All of this doesn't account for
* putting lakes back in that aren't present

* lots of islands and parts of shores that would typically have bays and parts that jut out, need reworked.

* great lakes need refinement and corrections

* elevation key map too blocky. Need a higher resolution one while reducing color count
This can be solved by introducing some noise into the elevations, varying say, within one standard div.

* mountains will still require refinement to individual state geography. Thats for later on

* shoreline is too smooth, and needs to be less straight-line and less blocky. less corners.

* rivers need added, not just large ones but smaller ones too

* available tree assets need to be matched, as best and fully as possible, to types of trees represented in biome data, so that even if I don't have an exact match, I can still place *something* thats native or looks close enough to what you would expect in a given biome.
Ponderosa pines vs white pines for example.

This also doesn't account for 1. major and minor roads, 2. artificial and natural attractions, 3. other major features people in any given state are familiar with. 4. named places, 5. infrastructure, 6. cities and buildings and towns.

Also I'm pretty sure I cut off part of florida.
Woops, sorry everglades.

Guess I'll just make it a death-zone from nuclear fallout.

Take that gators!

Why does google do this? It's supposed to be a map, not a fucking travel guide, I want to see the motherfucking map that it so ironically calls itself
Swallow a Collins road atlas whole you fucking impostor.

Just spent an hour looking at the NYC Subway maps vs the direction Google wanted me to take.

Google found the most efficient way is to take E train then transfer to R which then goes back a bit like a U-turn to get to my stop.

Then looking at the subway map, I can just take the R train... Since none of these trains are express... How the fuck did Google think that A-B-C is faster than A-C....

I can't sleep whenever I remember ,few year before I paid $25 for ethical hacking workshop and they show us inspect element n SQL map

I finally actually used a map reduce in code. Time to apply to Google!

At my last job, I created a Google Map for a client, where you could click on any department from France, and it would tell you about all the antennas (think "outpost") of his society. I used a Google Fusion Table where I registered everything: the datas to display, the coordinates for every departments and for every region.

I then wrote a 15-pages long document to tell how to maintain that, since I used my personal Google account to create the map. Anyone having a full access to the website should be able to recreate the map from nothing and witout writing a single line of code.

Then I switched project, the company kind of fucked me over, and I just received a mail saying that Google Fusion Table will be put down in a year.

I just hope they didn't receive the mail.

I am currently refactoring some code which exists before my time in this company.
The code was so inefficient before. To put into perspective for every function call it used to loop through some data 100+ times .
I replaced it with a map and voila, no more loops anymore.
The person who wrote this code don't even realise how bad his code was. He sits besides me writing more stupid hacky code for other parts of the app.

Unreal Engine adventures:
me: So ok, I need a map from int to String
Unreal: ya but it's called TMap, FCompactPoseBoneIndex and FName.
me: ..uhhh ok whatever
...
me: ok for debugging, please print this
Unreal: FName is not a string
me: k. Fname.toString().
Unreal: ya but it aint a TChar array now
...
IT'S A FKING STRING JUST PRINT IT. And the other guy is still an int with extra steps! Come the fuck on now....
I mean, honestly, a logging function that cannot print a fking FString? sigh...
Man, I miss python and blender...

Someone 3D printed the original Legend of Zelda world map!! I WANT ONE!!

Bitch followed me to the restroom.

Map of the Internet according to xkdc.

I genuinely just found solution to a dev problem in an xkcd comic.

I defy anyone to come up with a geekier solution to a problem than the Peter Carre map projection.

The solution to missing esc key is to map it to caps lock, like we were ever using the caps lock......

Now cut the ranting, you have a solution

Basically every time a designer thinks they made the perfect design and that if the program works by itself that's it. No man, I still have to spend hours trying to make every element of my program map to the elements you put for me to use. Give me time!

How many programmers does it take to change a light bulb?
64
One that fixes the problem and doesn’t care it’s a hardware problem
60 that later states how it could have been done differently and in a more efficient way
And three that continue on the thread discussing how the light bulb is not needed as it’s possible to create a perfect map of the room and how that could be achieved

@dfox Yay for new items and desks, but I'm still not seeing my world map desk, and that should be a must. Everyone has one like that, no?

My God is map development insane. I had no idea.

For starters did you know there are a hundred different satellite map providers?

Just kidding, it's more than that.

Second there appears to be tens of thousands of people whos *entire* job is either analyzing map data, or making maps.
Hell this must be some people's whole *existence*. I am humbled.

I just got done grabbing basic land cover data for a neoscav style game spanning the u.s., when I came across the MRLC land cover data set.

One file was 17GB in size.

Worked out to 1px = 30 meters in their data set. I just need it at a one mile resolution, so I need it in 54px chunks, which I'll have to average, or find medians on, or do some sort of reduction.

Ecoregions.appspot.com actually has a pretty good data set but that's still manual. I ran it through gale and theres actually imperceptible thin line borders that share a separate *shade* of their region colors with the region itself, so I ran it through a mosaic effect, to remove the vast bulk of extraneous border colors, but I'll still have to hand remove the oceans if I go with image sources.

It's not that I havent done things involved like that before, naturally I'm insane. It's just involved.

The reason for editing out the oceans is because the oceans contain a metric boatload of shades of blue.
If I'm converting pixels to tiles, I have to break it down to one color per tile.
With the oceans, the boundary between the ocean and shore (not to mention depth information on the continental shelf) ends up sharing colors when I do a palette reduction, so that's a no-go. Of course I could build the palette bu hand, from sampling the map, and then just measure the distance of each sampled rgb color to that of every color in the palette, to see what color it primarily belongs to, but as it stands ecoregions coloring of the regions has some of them *really close* in rgb value as it is.

Now what I also could do is write a script to parse the shape files, construct polygons in sdl or love2d, and save it to a surface with simplified colors, and output that to bmp.

It's perfectly doable, but technically I'm on savings and supposed to be calling companies right now to see if I can get hired instead of being a bum :P

My job pains me sometimes ...

"Issue: Maps aren't working properly."

Can anyone guess why?

Dear person who make the buttons on the company website using map and pixel counts. why.

Excited to start learning some backend for the first time while building a side project! First experience setting up a dB, map tile server, api, geocoder, etc. to make something completely self-hosted! 😊

So, my company pays thousands and thousands of euros just to show map and enable geocoding, a bug in google maps prevent Google Maps to work in Cordova and it's blocking us from deploying. After days and days of research I understand I can't solve it and I open an issue on google platform. Result: Severity -> S4, Priority -> P4

Same as when I go gym..
Deep breaths to get calm,
focus mind on clarity & stillness
then visualize, map & draw out exactly what I'm going to do and how I'm gonna go about it.
Finally, execute.

"Let the design team be the design experts. Your job is to be the business expert. Ask them how their design solutions meet your business goals. If you trust your design team, and they can explain how their recommendations map to those goals, you’re fine. If you neither trust them, nor can they defend their choices it’s time to get a new design team." - Mike Monteiro

Map/filter/reduce in a tweet:

map([🌽, 🐮, 🐔], cook)
=> [🍿, 🍔, 🍳]

filter([🍿, 🍔, 🍳], isVegetarian)
=> [🍿, 🍳]

reduce([🍿, 🍳], eat)
=> 💩

It is map of various devices connected over public IP to internet. Any interesting insights or comments that you can infer from this map?

I'm working on a pretty Plotly map. To learn how to use bubble graphs, I've copy-pasted the example and modified it.
The example is ebola occurrence by year, Plague Inc style. So naturally I need to add some countries. For testing, of course.

Ebola for everyone! Yay.
I like my job.

Have you ever played Zelda: Breath of The Wild?
Have you seen this system where you set a point on the map, and see a colum of light going up from this point with the Sheikah tablet?

Man I'd love to do that in an augmented reality system on a smartphone 😍

Do we have something like devRant world map or kind of?

Ugggh. Has anyone else on here worked with MFC?

I've been updating some legacy software and it's been like wading through a swap that was caused by a malfunctioning trailer park septic system: no map, and mostly shit with the occasional nasty surprise.

Please fucking tell me there's a better cleaner way to write this render() function?

The use of so many "in-line" code evaluations, arrow functions, (), {}, ...

Just spent like probably 30 minutes just trying to figure out what closes what...

And the author is inconsistent?

Sometimes he uses map( location => { return ... })

other times he uses setState((prevState) => ({ key: this.state.keyValue}))

And there's no note as to why... are they interchangeable, used in specific cases, does it matter????!!!!!!

Or is he just trying to demonstrate 1000 different ways you can say the same thing in JS?

front end developer map

I'm building a cross platform mobile app for this sales company to manage sales of each Van Sales Representatives. The app displays details of the customers; name, address, etc...

After demo, they requested for a map inside the app, specifically on the screen that displays the customer details for easy navigation by their VSR.

All attempts to convince them to use Google maps failed :(

Work on a Python mapping project, get everything right except changing color of points on the map. Take a long break on that project, come back and realize I made a capitalization error 😂😂

How to kill Jira Backlog in one simple step:

(Bottom line: it can be fixed from User Story Map to something normal)

if only there was a native structure that supports find and map methods in js...

PUBG's releasing a new map, codename Kiki...

Devs who use the array map method for purposes other than generating a new array, and who use an empty return statement to satisfy the linter, should receive a slap in the face. A gentle one, but a slap nonetheless

Just a short reply to whoever deleted his rant because he didn't read the JS docs.

map is a map. You don't just dump a function call into there. You map the value to el and the value is then set to the function result.

This works:
new Array(38).fill("10").map(el => parseInt(el));

Question and Update.
First of all, I would like to thank @ScriptCoded for an idea in the previous post, so then I have beautiful terrain now, and the complete world map generated like plots, and each of them consists of 5x5 different plots defined by neighbors :) Hired a digital artist who is working on much nicer plots as well.

The new issue is regarding the zoom.
The map is saved as JSON with the pixel-perfect location of each generated plot so I am detecting the collision with the mouse based on their location. After I zoom in, the script is still comparing the pixel location of the element, but the real screen is scaled already so the pointer is off (image2). The problem is described in image3 as well. How can I still get the canvas relative value of the mouse instead of the x,y coordinate on the current zoomed screen?

Today I was asked a question on JavaScript regarding the difference between normal `for` loop and a `map` function on an array with regards to closures. Can anyone help me understand? #javascript #interview

['1', '7', '11'].map(parseInt)
// and this returns...
// drumroll please
[1, NaN, 3]

WAT

I just played a few old maps I and a few steam friends made and it brought back the feelings. I had to open a few maps in hammer (Level editor) and see myself around.

I completely forgot the controls in hammer and had difficulties to recall how to import assets from a custom map. Everything was clunky.

It kind of makes me sad when I look back. I wish I could still map - but the school will start tomorrow and I guess I have no time for that. The same thing happened with playing the piano. Once I reached a certain skill level, I stopped although I loved it. I stopped progressing.

Unreal engine isn't fully my thing, I feel uncomfortable working in it, though I still want to make games. I found myself not opening it for a month or so.

Data representation is one of the most important things in any kind of app you develop. The most common, classic way to do it is to create a class with all the fields you want to transport, for example User(name, lastName). It's simple and explicit, but hell no, in my current company we don't play that kindergarten bullshit, the only way we know how to do things here is full hardcore. Why would anyone write a class to represent a Song, a Playlist or an Album when you can just use a key-> value map for pretty much everything? Need a list of songs? No problem, use a List<Map<String, String>>, OBVIOUSLY each map is a song. Need a list of playlists? Use a List<List<Map<String, String>>>... Oh wait, need to treat a value as a number and all you have are strings? That's what casting is for, dumbass.

No, seriously, this company is great. I'm staying here forever!

LIRR system rant 2 - there is a thing called a sensor. Can you please paste them on your trains so we know on a real-time map where the train is. If it's 8 miles away when supposedly 'on time' we don't have to freeze on the platform. It's 2016 not 2007.

Google map JS API is a fucking abomination

It's clearly in the contract people.
You walk a client through the entire contract and come launch they want to add pages and change layouts without paying extra because they have 24 hours to launch.
What don't you get about "you approved the site map, layouts, and designs which is what we quoted you for, contract clearly states how much per extra pages and how much to change layouts and designs after approval and work processed"

I just spent 4 (four) hours debugging why my perlin noise used the same gradient for every point. Turns out I forgot to assign the seed for the random generator so it defaulted to 0. (I seed it every round with the map seed and coordinates so I don't have to store anything for visited regions)

So, how's your sunday night going?

Testing a script embed plugin I am building on various random websites, and came across this.

Like, bruh; have you ever heard of a javascript map? Basic functional programming? Or even a switch statement?

It's the same statement, over and over again, but with different parameters. Even old javascript had enough tools to do this with at least a basic stench of "efficiency"

Toilet Dev rant - my urine went into mute mode when that creepy business head almost 7 feet stood in the urinal next to me and said hi. What the fuck from such height he can easily view the entire map of the urinals and what not. And why the fuck my urine went mute not even a single drop went through. I hate it

There are so many:
Arch Linux, Krita, LMMS, Open Street Map and many more.

Well i am working as an intern at this startup. Initially it was all simple crons and database. After one month one of the founder asks me to map two tables, create an api, integrate a fucking payment gateway and i am now left with a lot of work and confused state of mind.

PS: i am first year cse student

Yesterday had fogged mind all day long. I felt like the biggest r-word in the world. Couldn't even map some simple API arrays.

Tool Laterus just makes me woke AF.

Been coding hard today since I turned on the pc

That feeling of utter uselessness when you read "Really? That took you all day?" in your gf's eyes when (proudly) showing that you finally got the map markers working reactively on map drag.

Management: let's be agile... we can all meet and discuss a project that will take more than likely 6 - 12 months but you guys can estimate and create a road map....
Engineer: I'm not sure you understand agile

:-(
Firefox doesn't map correctly the controller (Xbox One) but it works on Chrome. (FF on Android Works)

This is literally the first time (for me) that something works on Chrome and not on FF. (at first shot)
usually it is the opposite.

One point for Chrome (this time)

but still 6,022*10²³ Points for FF.

Stop changing maps and focus on THE map -- de_dust

There are days I like to pull my hair out and create a dynamic 4D map that holds a list of records. 🤯

Yes there's a valid reason to build this map, generally I'm against this kind of depth 2 or 3 is usually where I draw the line, but I need something searchable against multiple indexes that doesn't entail querying the database over and over again as it will be used against large dynamic datasets, and the only thing I could come up with was a tree to filter down on as required.

!!THE WORLD IS COMING APART!!

How in gods name did Putty manage to map a SSH tunnel to port 83306 and MySQL Workbench just didn't care and worked?!?!

public static Map<Integer, List<Integer>> stuff(arguments) {
HashMap<Integer, List<Integer>> map = new HashMap<>();
method(map, otherVariables);
return map;
}
public static void method(HashMap map, otherVariables) {
map.put(things);
}

So... You know how to return a map from a method. Then why do you create the map outside the method and make it an argument that does not get returned, making it confusing because the map gets created empty, given to a different method, then returned, making it look like you're returning an empty map...
...instead of just creating it inside the called method, returning it and assigning it to a map in the calling method? Even if you think that would create another map (it doesn't), the compiler is intelligent and can optimise that away.

And that is why I map caps lock to any f*ing thing on earth but to the caps lock.

Today I actually used a data structure other then List or Map for a real problem!!!

This is like a once in a year, several years thing? (Technical interviews don't count)

Can anyone recommend a good free blogging site?

Was going to use wordpress but im not paying 130 AUD just to map it to a sub domain.

Blogger has very few options when it comes to themes and custom themes.

And tumblr... Is tumblr (I was using it but decided to rid myself of such filth)

Have you ever worked with leaflet.js to display openstreetmap? I do and its great.

But now I want to display multiple markers on a map and the map somehow only renders random three markers. Wtf?

I'm lost. All results on google show me how to do it right, but it just doesn't work.

It was a little Java Swing Application for my friend who had to maintain a little notebook for his insulin values.
The device he used to read his values, saved them as a csv-file, so it was pretty easy to map them to a readable format, so he didn't have to maintain that notebook.

He never used the App. He got an implant that manages it for him.

You know how people want to avoid collisions with a hash map?? Well a buddy and I went to a hackathon about 2 years ago, and the idea we had was kinda cool, but to get a prototype working, we decided to defy the logic of a hash table and purposefully cause collisions with a hash map. I took a look at the project and it is soooo poorly implemented.

That feeling when you have to rebuild and redeploy project for the third time in a row because java can't map Swedish letters. About 20mins for each try.

When your frontend does not really get what your backend is trying to say...

This is oalley.net. Apart from the fact that their frontend and backend do not work together very well, it is a nice tool to mark reachable areas on a map based on the starting point, the means of transportation and the maximum time.

How do I become good with functional features(map,reduce,filter,zip,flatmap) in Javascript and Python?

It feels so alien. I'm so used to writing plain old loops.
Reading and undersranding this kind of style in other people's code is really hard for me, especially if all this is happeining on the same line.

Just spent 30+ hrs on an error that was due to using flatMap instead of map.

I feel stupid!

Pro Tip: Never try to learn Spring without learning java properly.

Forgetting every day tasks...

So I can use map, reduce, filter in my sleep, have memorised huge chunks of valuable programming information.

Today I went to the gym and laced up my jogging pants, looked at the vogue knot I'm supposed to tie to prevent them from falling down and my brain just said:

"Fucked if I know how to tie that!"

During an interview:
Using map is wrong. Now implement bisection search.

I only boot into Windows for gaming and making normal map for MC texture pack, you?

Converting javascript/ typescript Map to json
or python date to json

or anything complicated to json is mostly ending with implementing serialization patterns

With date it’s so annoying cause we have iso standards that every language implemented or have libraries

so typescript doesn’t recognize Map<string, string> so you have to convert it to array and then to object

with python you need to make your own serializer / deserializer

So much waste of power usage that if only Greta know it she would say ‘how dare you!’
It can stop global warming.

Currently working on a Stardew Valley mod.

I'm injecting a custom map as a .tbin file and loading it.

Works perfectly fine.
Can edit it ingame, plant crops there and shit but when I save and reset the game.

Bam changes gone.

Apparently I gotta write an extra method for saving the current map, in the game back into the base map which exists as a file in my mod's folder.

AND GUESS WHAT.

NO IDEA HOW TO FUCKING DO THAT.

SMAPI IS SO HORRIBLY DOCUMENTED FUCK IT

Here at the end of high school they make you create a sort of mini-thesis and/or a conceptual map. I found mine in midst of full blown bedroom chaos, dated one year ago (it's in italian because I am italian but you can definitely ask for translation). I got that fucking diploma despite all the issues I had and still have. Fuck 'em.

Fuck off slickplan. Your subscription model is not for the little guy. i love your site map builder, but I cant justify $118 a year for my 6-8 annual site maps. i’ll use keynote. if you price stuff properly then you’d have more subscribers. greedy cunts. it tends to be the way with a lot of online services. people will gladly pay, but it’s gotta be of value. you think twice when you start getting pricey.

The worst part about switching code from python 2 to python 3:

`map(myfunc, mylist)`, behaves differently, but won't throw an error. It will just show up as nothing.

Is there a Map like class in Java that has

getKey(value), getValue(key).

Guess not hard to implement but why reinvent the wheel..

I am currently lost in translation.
Damn, standardization are important.

I am working on integration of biggest payment company in Japan. Their technical guys doesnt know much Emglish.
Their documention of APIs were literally translated into english without any standardization by their dev guys.

And now I am trying to map what they mean in standard terms.

Psst I no english speaker.

Reading through the bugs list on Trello...

- change colour and style of button to make it more prominent
- change default for select box
- add a popup to explain the UI on 1st visit
- if I don't save the entry, show alert to user on exit
- remove the map button under the map that links via auto scroll to the map above it
- remove the settings options for the items we designed but you couldn't implement due to lack of time / budget / low priority

It goes on, seriously...

FFS

This just in, a message from firstparty watching the customer test what we did:

"the chines client has a problem with the Picture of the Map (at Team).
Becaus of the policital situation in china he asked to remove the blue highlighted border and only show the neutral map.
Since Daniel is in holidays, can you do that? If not, can we than just remove the picture, an replace at with a chinese flag please?"

I saw that, and chuckled, thinking "oh yea, i almost forgot for a moment that china is ass hoe".

.map() implies the existence of .treasureMap()

It reaaaally annoys me when my business logic is sound but the data is corrupted.

For example, find duplicates in a HashMap<String>.. but I didn't take into account the input could contain a space either before or after.. so I end up wondering: if a HashMap only contains unique keys, how come the count of items in the map is the same as the count of the input keys?! Well.. spaces were the culprit.

"12345" != "12345 ".. and therefore the Map sees it as two distinct keys..

What an annoying bug.

Lesson learned: 1) Sanitize input first and never trust it. 2) Never make assumptions

For me, PHPStorm's mini-map is ugly. Nothing compared to VS Code and Sublime Text.

I will uninstall it now.

The person who wrote this map framework in our old fat client has such a deranged mind that 4 days in I still haven't fucking clue how it works

Implementing a for loop in js because I need to skip some elements in a map as I transform. I'm feeling dirty

* cries in functional *

Our app has web scale data. So let me take all my tables from a relational database and map them one to one to a collection in a document database.

Today there was a question on the react native forum asking how to map an array..... ([].map(mapFunction))

1) it's the wrong place for the question

2) like 80% mentioned ramda, lodash, underscore :(

Hey ya'll back with another college boi question.

I want to develop a web server akin to that of jackbox/among us. Where each session has like an 'ABCXYZ' style code, and i assume are using TCP sockets on the back end.

I'll be writing in Go cause I <3 Go and its a chad language. Anywho, am i supposed to spin up a new websocket server each time someone wants to make a room? Or do i have one websocket server and some sort of map of rooms.

gameRooms := map['id_string']clients

Anyone have any suggestions for this?

Devs with gaming mice.
What hotkeys / macros do you use?

For years I've been using gaming gear with additional buttons to map various hotkeys and macros to speed up my work flow.

Let's share the use cases here.

Got a few
Crystal reports - words cannot describe how much I loathe this

Sybase ASE or IQ - both are just a hot mess to setup properly

Not a service now fan either

Esri map processing - basically entirely undocumented, slow, old fucking hate it

Arc GIS online - ridiculous licensing issues, undocumented APIs are given as official answers from the dev team, massive pain in the arse

What's your opinion on functional shortcuts and 'hacks' in many languages, like map/reduce/filter, ternary operator, lambdas,inner/anonymous classes?

Imo they can make development faster and more efficent but they make the code very unreadable, especially if someone else has to read it, Therefore I try to use them only when it's appropriate. My dev friends use them too much and it makes reading their code a hellish experience, especially in Javascript with Rx.

when your team member writes 30 lines of looping code which is really just a 1-line filter & map call.

It's always great idea to map common keyboard shortcuts to something completely different, such as when IDEA sets the default behaviour of Ctrl+Y to "remove the line under caret". Thanks guys, I love surprises, next time try something with ctrl+c.

Note to my future self: when installing the IDEA again, remember to remap the ctrl+y..

that feeling when you want to take off a few days of work to REALLY research Perlin noise and displacement map filters.

This was a project for school, we had to simulate an app that traced bus routes over a map.

All the teams but mine do it in Java (desktop app), we took another approach and did it on Android with the Maps API.

I had fun coding a parser, this parser job was to read a file and load the bus routes and draw them on the map.

It was structured like:

NAME
COLOR
<lat, long>
<lat, long>

The fun part was coding and telling my teammates "chill out, it will work", so we finished, built and run and... done! First code working smooth AF.

I know it's a simple parser and a simple app, but it was a nice feeling not having to debug the app.

Question: which is better approach?

1. Use push notifications to tell react website that new data is available

OR

2. Use SignalR (similar to socket.io) and push data in real time?

The down side of SignalR is server needs to map connections --> use more memory while push notifications doesn't require that

Just figured out "code map" and "code clones" on VS 2015 (don't ask me why I didn't know these features)

Thought I should try it on my newly created application for a client (+/- 1500 lines of code C#)

Came across 1 duplication, 0 unreferenced classes or members and no circular references

I'm just awesome

So once again, I'm planning for a new website I'm developing, a little side project. I tend to put pen to paper and map out what features I want to include and see where that goes.

It's got me thinking how everyone else likes to plan for their personal projects and if I'm missing a trick?

So we map conditionals based on the form labels that the client can change and don't autoupdate them.
