Search - "sqlite"
I'm working on my own code editor with 'multiplayer', option to draw stuff, option to design algorithm schemes, option to browse SQLite databases and most importantly - I've based entire interface on HTML/CSS/JS and entire backend on C# and PHP, so it works both online (via browser) and offline (via program).
Tell me whatchu think, it's still work in progress.
(I've removed the name of it so when I share this project with my future employer, he doesn't connect the dots)17
My last special snowflakes teacher story. This happend last Friday.
Background: we had to do a "little" project in less than 2 weeks (i ranted about that) and got our degree on Friday. I did a perfectly fine meal suggester, with in my opinion one of the best codes i've ever written.
After getting my degree (which is totally fine and qualifies me as IT technician/ "staatlich geprüfte Informationstechnische Assistentin") i asked him what my grade for the project was.
Me: what was my grade for the project again?
Him: i left it at 90%
Me: why exactly? You seemed to be really excited and liked it obviously. And there was no critique from you after my presentation.
Him: yadda yadda. I can't give you more. Yadda yadda be happy i didn't lower your grade.
Me: why would you lower my grade? This doesn't make sense at all. I matched all your criteria. You wanted a program everyone loved, everyone wanted to buy. There you go. I made exactly that.
Him: i can't give you a 1 (equals an A)
Me: why not?
Him: you wrote to much. I didn't want so much (he never specified a maximum). And you used to advanced code. And there were so many lists and ref - methods. The class couldn't benefit from it.
Me: Excuse me!? The only "advanced code" i used was a sqlite library. And i explained what i did with that. What do you mean by "so many lists" and ref-menthodes. In which methodes am i using ref?
Him: I don't know, i just skimmed through the code.
Me, internal: WHAT THE FUCKING HELL!?
Me: so you are telling me, you didn't even read my code fully and think it is too advanced for the class? And because of that you give a 2 (equals a B)?
I just gave him a deathstare and left after that. What the hell. Yes, i used encapsulation - which is something we hadn't done much in class. But the code is still not more advanced because i use more files -.-16
Behold, the SQLite new Code of Conduct:
May this be a guide to all current and future projects.
I don't think it's wholly a joke, but it is a jab at those who seemingly cannot live without having a CoC everywhere. Especially in projects, they do not actually participate in. Now watch as this gets blown out of proportion, because this will make some people really, really angry.
I truly hope this stays up!12
Senoir dev was assigned to make a webapp for billing
Dude uses dreamviewer and writes code like a bitch
Phpmysqljqueryhtml whole thing mixed very badly and undocumented
His function name format fun_1()
a simple update cost him a day,
Told him to use brackets atleast and also a framework ,guy denies
Days go by
He learns a lot of stuffs from me ,like how to use inspect in chrome lol, how to use sqlite for small projects , and orm and frameworks.
He used to pin his mistakes on me, so that boss gets angry on me
Then i quit the job
2 years went by
Now he is unemployed, nobody wants a 24 year old plain php coder and template editing web developer
Anyway I hired him, he was my first senior, whatever he did,it didnt matter to me, bcoz i remember
the days we spent on the same hall right next to each other coding in php,
days we brainstormed to fix a div
Also the days we ate lunch and breakfast together6
Set out to copy the iOS alarm on android because a) android's stock alarm is fugly and b) all other sleep reminder apps either offer me way too much or no functionality.
Week 1: "Oh, custom UIs need a lot of math... Ok."
Week 2 "Why on earth is my ram usage at 400 mb?!"
Week 6: "I have come to the realisation that android's ByteArrayDecoder should burn in hell.
Week 7: "Man... They sure made the management of intents and pending intents a pain."
Week 10: There. It works. Two classes, 7000 lines of code.... Hmmmm maybe apply MVP."
Week 11: I discovered embarrassment driven development, throw away all my code and start from scratch.
Week 12: Oh ButterKnife, where have you been all my life?
Week 17: I might actually finish this in my life time!
Week 28: Man, this MVP and managing Context, intents, SQLITE DB and pending intents do not mix well.
Week 46: I discover RxJava and Dagger 2
Week 47: I discover that the 'V' in MVP does not refer to an 'Activity'
Week 48: My StudyBudy says to me "Man, exams are only a month away!"
Week 49: I put all your code in my github, delete it locally and focus back on being a student.2
OFFICIALLY COMPLETED A PROJECT!!
Its not anything too fancy but I am very proud of it.
It is a simple C# (.NET Core) Console application. that also uses SQLite
if anyone wants to see it heres the repo:
A little late but whatever.
About half a year ago, I started working on setting up self hosted (slippy) maps. For one, because of privacy reasons, for two, because it'd be in my own control and I could, with enough knowledge, be entirely in control of how this would work.
While the process has been going on for hours every day for about half a year (with regular exceptions), I'll briefly lay out what I've accomplished.
I started with the OpenMapTiles project and tried to implement it myself. This went well but there were two major pitfalls:
1. It worked postgres database based. This is fine but when you want to have the entire world.... the queries took insanely long (minutes, at lower zoom levels) and quite intimate postgres/tooling knowledge was required, which I don't have.
2. Due to the long queries and such, the performance was so bad that the maps could take minutes to render and when you'd want that in production... yeah, no.
After quite some time I finally let that idea sail and started looking into the MBTiles solution; generating sqlite databases of geojson features. Very fast data serving but the rendering can take quite some time.
After some more months, I finally got the hang of it to the point that I automated 50-70 percent of the entire process. The one problem? It takes a shitload of resources and time to generate a worldwide mbtiles database.
After infinite numbers of trial and error, I figured out that one can devide a 'render' (mbtiles aka sqlite database) into multiple layers (one for building data, one for water, one for roads and so on), so I started doing renders that way.
Result? Styling became way more easy and logical and one could pick specific data to display; only want to display the roads? Its way more simple this way. (Not impossible otherwise but figuring out how that works... Good luck).
Started rendering all the countries, continents and such this way and while this seemed like a great idea; the entire world is at 3-4 percent after about a month. And while 40-70 percent generates 10 times as fast, that's still way too slow.
Then, I figured out that you can fetch data per individual layer/source. Thus, I could render every layer separately which is way faster.
Tried that with a few very tiny datasets and bam, it works. (And still very fast).
So, now, I'm generating all layers per continent. I want to do it world based but figured out that that's just not manageable with my resources/budget.
Next to that, I'm working on an API which will have exactly the features I want/need!13
Not only Windows can show this "strange" error messages: Today I got this beauty while importing an SQL-dump.
(Translation: "Error on import: error on statement #1: not an error. Execution will be aborted and the db will be reset.")
So we had this legacy Objective-C codebase for a mobile app that was actually pretty good: I'd inherited the codebase and spent the past several years gradually improving it and I was actually quite proud of the work I put into it. So of course management decides to scrap it (with NO consultation from the engineers) and outsource a complete rewrite of the app in C# for Windows Universal.
Let me tell you. That code was without a doubt and without exaggeration the *worst* code I've seen in my close to 30 years of experience as a developer. I mean they broke every rule in the book, I'm talking rookie mistakes. Copypasta everywhere, no consistent separation of concerns, and yet way too many layers. Unnecessary layers. Layers for the sake of layers. There was en entire abstraction layer complete with a replicated version of every single data class *just* to map properties in pascal case to the same property in camel case. Adding a new field to a payload in the API amounted to hours of work and about eight different files that needed to be modified. It was a complete nightmare. This was supposed to be a thin client, yet it had a complete client-side Sqlite database with its own custom schema (oh and of course a layer for that!) completely unrelated to the serverside schema, just for kicks. The project was broken up into about eight or nine different subprojects, each having their own specific dependencies on various of the other subprojects in such a tightly-knit way that it made gradual refactoring almost impossible. This architecture was so impressively bad, it was actually self-preserving!
Suffice it to say it was a complete nightmare, and was one of the main reasons I ended up leaving that company. So just sayin', legacy code isn't always bad. :)
This is the most impressive testing document I have ever read. Props to the SQLite devs for doing things so thoroughly.
Contex: Working on a c++ frankenstein code (mixture of legacy and new stuff whith things depending on the client using it)
User Story: Migration from oracle to SQLite for half of the DB data
Summoner: One client wants to keep using legacy for now, therefore we need an strategy chooser templated singleton...
Satan 666 = Singletons + Static methods + Different compilation units
Result: 3/4 of the files of the full backend being modified for the migration.
Conclusion: When will be loaded on production company will probably lose many clients due to unspected bugs everywhere.
Insert potato here2
A remote SQLite database where huge blobs of JSON created by python’s pickle module were stored in a single cell. These blobs include things that should have been many-to-many, like users and competitions. This database (including the pickled python objects) was queried by API calls from an iOS app.
The webpage for (basically) the only movie theater chain is slow. The app, goddamn, is worse.
So I made an app to scrape the data and save it in a SQLite db for my use. However, there is one theater which doesn't belong to the same company. So I decided to also include it in the app.
But it sucks! I still have to find a way to automatically get the data from their shitty site.6
I’m stressing out man. I can look at let’s just say a sorting algorithm for now. I can look at that insertion sort and I can understand what’s happening, but if you were to tell me I was supposed to be able to write that just based off a description I couldn’t. I need to be able to design and understand algorithms but I don’t know where or how to start. There was some course I was gonna try and see what that does. I put aside JS completely to focus on C# but I’m just stressing out over here. I learned the basics of C# although I feel like I’m learning it wrong but I’m moving on to SQLite and it’s my first Database experience and it’s confusing me and I also don’t know how I’m going to be able to use it for my future applications yet I’m just expecting too much out of me idk I love programming but sometimes it’s a cruel mistress13
So I’m working on this project I’ve been working on for like 3 weeks and I finally got this feature to work but it had a bug and I shit you not fighting this program was like playing through bloodborne for the first time again. It got to the point where I started naming the testing files swear words or stuff like “itshopeless”, “maybe”, “maybe2”, “pls”, etc but I finally after fucking hours passed, bug slaughtered. And I’m now exhausted
Continued from https://www.devrant.io/rants/575042
Time for a new great collab project!
Read the above rant I posted previously to see what our class is...
So the teacher(who uses visual c++ ide made in the 1990s) said to make an android based application or make a game but without using any block programming (like scratch) which means for android app development, we should make in java, js, c#, or any app makin' programming language. For game development, we should use either unity(yes, I am good at it) or unreal or gamemaker or buildbox. LibGDX is not allowed (I wonder how the teacher knows this library... strange).
Any ideas upon making apps or games? Prefer apps btw...
Something using SQLite or database will be appreciated but not dull student management system.
Any ideas appreciated.2
Have you ever wanted a feature to be a certain way but you had to settle with something easier and less cool/impressive?
I just had to and it’s very dissatisfying.1
During my first project in one of the SQLite statements I didn’t realize that it needed single quotes since I was new to it. So I brushed that off but when working on the next function for the program 8 hours were dedicated to debugging to only realize that the error was caused because I forgot the fucking single quotes. FUCK
Quotes are paraphrased (unless *) to protect the incompetent and stupid (or more the case: client and I'm reducing risk of exposure)
Situation: We have a program that opens sqlite database files. Occasionally new versions of the program needs to upgrade these files.
Program UI: To proceed you need to upgrade your database. It is recommended you backup your database before proceeding. Hit Yes to continue or No to abort.
Client: How do you back up a model once it has upgraded? If I hit No the program closes leaving me no option to backup the model.
Support: *The easiest way of backing up a model before upgrading is creating a copy of the file and keeping it in a separate folder*
Client: *Haha forgot about being able to do that outside of* <program name>
TL;DR: engineer in technical role who is probably getting paid $150k+ forgets it is possible to make a copy of a file.1
SQLite DB + Google Drive == Love
Just ran my app installers (in projects folders that i copied) and set the DB file on startup.
Could end up with a merge conflict if the app is running on both PCs at the same time though... hm....2
So my customer wanted me to collect Big Data using SQLITE... (Yeap SQLITE, like wtf...)
F*** my career.14
As an emerging Android developer, I must say I HATE SQLITE AND CONTENT PROVIDERS!! So much code for such little functionality! Pro Android devs, does the process get any less tedious down the road with more experience?6
How my day started yesterday.
Luckily It fixed itself, but i was starting my day thinking I should just rewrite a function that wasn’t working so I could test some stuff but instead just decided to debug and thankfully I did that because the error was being caused by a lack of quotes and when I saw that I changed it.
It worked flawlessly and it’s my first project to use SQLite so I stood up and walked around because I was just so amazed because it was working how I planned and how I intended.
That feeling that you get from a project that works how you wanted it to is unbeatable
My another attempt to write something in rust and I wanted to try tauri as it’s promising competition to electron.
Why use tauri not electron?
So it took me entire weekend to create draft plugin to interact with sqlite database.
Documentation of tauri is inconsistent. I understand that cause it’s young project and plugins architecture changed frequently.
Moreover my knowledge of rust is near to zero. But overall it was worth it. I like what I achieved.
I know I wasn’t fancy with my implementation. I just created file database connection from json configuration and managed to receive string sql statements. I just print results with rust to console for now.
I will add sending back results later this week.
For me tauri is already better then electron cause code is clear and there is no workaround ( except singleton with connection - cause of limitations of my rust knowledge ).
Live long tauri and fuck you electron.
if you’re interested.2
Lessions I learned so far from my first big node/npm project with tons of users:
1) If you didn't build something for a while, expect 3 hours of resolving version conflicts for every two weeks since the last build.
2) Even if the tests pass, run the containers on your own machine and make sure that the app doesn't randomly crash before deploying
3) Even if the app seemed to work on your own machine, run the tests again in an environment mimicking prod at most 15 minutes before replacing the running containers.
4) Even if all else indicates that the app will work, only ever deploy if you expect to be available within the 4 hours following a deployment.
5) Don't use shrinkwrap for anything other than locking every version down completely. A partial shrinkwrap will produce bugs that are dependent on the exact hour you built the app _and_ the shrinkwrap file, and therefore no one will ever have seen them other than you.
6) Avoid gyp, and generally try not to interface too much with anything that doesn't run on node. If parts of your solution use very different toolchains, your problems will be approximately proportional to the amount of code. And you'd be surprised just how much code you're running. (otherwise it's more logarithmic because the more code the less likely a new assumption is unique)
7) Do not update webpack or its plugins or anything they might call unless you absolutely need to
8) Containers are cool but the alpine ones are pretty much useless if you have even just one gyp module.
9) There's always another cache. To save yourself a lot of pain, include the build time in every file or its name that the browser can download, and compare these to a fresh build while debugging to assert that the bug is still present in the code you're reading
+1) Although it may look like it, SQLite is far from a simple solution because the code and the bindings aren't maintained. In fact, it'll probably be more time consuming than using a proper database.3
This is a simple Gmail terminal client that can perform filtering and few actions on the filtered emails. Used python 3.7 and sqlite to store them.1
I have to try to Learn PHP with SQLite in a fucking night it’s not even for anything big it’s just a basic login page for some students that are coming in to visit. but it has to all be working on this Friday. fuck. I’m just gonna learn enough to get by these few days. Then continue what I actually have been doing I guess6
On Friday, I was playing with the ChatGPT integration in DBeaver. I was using the DBeaver sample SQLite database. This database has a couple of tables, among them Album and Artist, where Album has a foreign key into Artist.
So, I asked it:
"give me a query that lists all albums from artists who's name starts with s"
The query I got back was:
SELECT * FROM Album
But then, I noticed that I wrote "who's" instead of 'whose', which would be proper grammatically. So, I changed that, and then I got this query:
SELECT * FROM Album WHERE ArtistId IN (SELECT ArtistId FROM Artist WHERE Name LIKE 'S%');
Hooray, that works! I'm not sure it's the best way to write the query... I might have written:
SELECT * FROM album a, artist r WHERE a.artistid=r.artistid AND r.name LIKE 'S%'
...I'd have to check to see if one performs better than the other, and consider which syntax I find clearer, but that's a separate issue, it's just nice to see a working, reasonable query generated because that's the point, after all.
But I found it interesting that such a minor error would cause it to not work, that's my main point.
Interestingly, it seems to have learned: I just tried the same thing, and I got the right query either way. So that's pretty cool.
It's a pretty neat feature and I can see some legitimate value in it. I'm pretty good writing SQL myself... I've managed to write some truly hideously complex queries over the years... but there are definitely instances I can recall where the query didn't seem obvious at the start, and having an AI that can MAYBE produce something that is AT LEAST a starting point is definitely something I can get onboard with.9
Data wrangling is messy
I'm doing the vegetation maps for the game today, maybe rivers if it all goes smoothly.
I could probably do it by hand, but theres something like 60-70 ecoregions to chart,
each with their own species, both fauna and flora. And each has an elevation range its
found at in real life, so I want to use the heightmap to dictate that. Who has time for that? It's a lot of manual work.
And the night prior I'm thinking "oh this will be easy."
(Also why does Devrant have to mangle my line breaks? -_-)
Laid out the requirements, how I could go about it, and the more I look the more involved
So what I think I'll do is automate it. I already automated some of the map extraction, so
I don't see why I shouldn't just go the distance.
Also it means, later on, when I have access to better, higher resolution geographic data, updating it will be a smoother process. And even though I'm only interested in flora at the moment, theres no reason I can't reuse the same system to extract fauna information.
Of course in-game design there are some things you'll want to fudge. When the players are exploring outside the rockies in a mountainous area, maybe I still want to spawn the occasional mountain lion as a mid-tier enemy, even though our survivor might be outside the cats natural habitat. This could even be the prelude to a task you have to do, go take care of a dangerous
creature outside its normal hunting range. And who knows why it is there? Wild fire? Hunted by something *more* dangerous? Poaching? Maybe a nuke plant exploded and drove all the wildlife from an adjoining region?
Having the extraction mostly automated goes a long way to updating those lists down the road.
But for now, flora.
For deciding plants and other features of the terrain what I can do is:
* rewrite pixeltile to take file names as input,
* along with a series of colors as a key (which are put into a SET to check each pixel against)
* input each region, one at a time, as the key, and the heightmap as the source image
* output only the region in the heightmap that corresponds to the ecoregion in the key.
* write a function to extract the palette from the outputted heightmap. (is this really needed?)
* arrange colors on the bottom or side of the image by hand, along with (in text) the elevation in feet for reference.
For automating this entire process I can go one step further:
* Do this entire process with the key colors I already snagged by hand, outputting region IDs as the file names.
* setup selenium
* selenium opens a link related to each elevation-map of a specific biome, and saves the text links
(so I dont have to hand-open them)
* I'll save the species and text by hand (assuming elevation data isn't listed)
* once I have a list of species and other details, to save them to csv, or json, or another format
* I save the list of species as csv or json or another format.
* then selenium opens this list, opens wikipedia for each, one at a time, and searches the text for elevation
* selenium saves out the species name (or an "unknown") for the species, and elevation, to a text file, along with the biome ID, and maybe the elevation code (from the heightmap) as a number or a color (probably a number, simplifies changing the heightmap later on)
Having done all this, I can start to assign species types, specific world tiles. The outputs for each region act as reference.
The only problem with the existing biome map (you can see it below, its ugly) is that it has a lot of "inbetween" colors. Theres a few things I can do here. I can treat those as a "mixing" between regions, dictating the chance of one biome's plants or the other's spawning. This seems a little complicated and dependent on a scraped together standard rather than actual data. So I'm thinking instead what I'll do is I'll implement biome transitions in code, which makes more sense, and decouples it from relying on the underlaying data. also prevents species and terrain from generating in say, towns on the borders of region, where certain plants or terrain features would be unnatural. Part of what makes an ecoregion unique is that geography has lead to relative isolation and evolutionary development of each region (usually thanks to mountains, rivers, and large impassible expanses like deserts).
Maybe I'll stuff it all into a giant bson file or maybe sqlite. Don't know yet.
As an entry level programmer I may not know what I'm doing, and I may be supposed to be looking for a job, but that won't stop me from procrastinating.
Data wrangling is fun.1
Why does the sqlite SUM function round down values?? WHY?
10333.03 is printed as 10333
This has caused me so many problems?
What is the solution to this?2
I've been wondering about SQLite, how it decides to execute your SQL and then generates byte code to do it.
Hypothetically if you were sufficiently familiar with the quarks of SQLite at a low enough level, one could craft web requests on sites running it, such that the results of each subsequent request, leave the SQLite engine in a particular state, no?
Suppose previous states, when interleaved with subsequent carefully crafted states, lead to execution and injection vulnerabilities.
Arent ideas like this what lead to the randomization of jump addresses in modern architectures?8
Anyone got some good recommendations for a Rust library that takes SQLite and lets you turn it into JSON?
I'm asking for a friend...also, I'm fairly positive the Puritans over at StackOverflow would have me crucified if I asked this one over there...1
Is MongoDB worth learning? I already use MySQL/SQLite but I was thinking of learning it. How is it any different aside from having no SQL13
Spent 4 hours working with a buddy before realizing our failing code stemmed back to using sqlite3 Npm package, which is asynchronous. Switched to better-sqlite3, a synchronous sqlite package, and alls good.
What's the purpose of an async DB anyway? Seemed like it made storing and retrieving data a huge hassle.
Two senior developers were baffled at why their Web application built using sql server wouldn't just instantly work using sqlite... The Web application uses some pretty advanced queries and ORM.1
Something very interesting today
I worked on an API feature and it was approved and merge to the stable copy of the project. But then comes the demo.
Now we used Heroku(this devil)
The database uses sqlite. I can register an account on the web application. But the user table has only the admin account even though i have successfully managed to register.
I dont know what sorcery this was!
I simply went with the saying "it is working on my local machine"
Only to realise minutes to the demo the build pack was not done well at the beginning...
What is life...
If you ever need a good example for bad API design, just use IndexedDB. While it might still be far above absolute zero, it should definitely be low enough for any practical purpose.
And as a bonus, it wouldn't actually have been needed if the SQLite status quo would just have been adopted as the standard back then. We could have a complete RDBMS with almost full SQL support in the browser...
Was motivated to do a project with ReactNative for Android but already stuck.
I need to read a SQLite DB file from /data/data/some.other.app/database/DB.db
Yes I am rooted.
1. How does I request root from the App (Android Pie)
2. What SQLite npm package can load from an absolute path. I found a few libs but they don't seem to be full access, just for dbs in the app's own data folder.8
Wow.... it seems Entity Framework with Code First/Annotations is FAAASSSTTTT vs using Fluent API. I don't mean writing the actual code but the DB file opens very quickly unlike my last attempt years ago...
Or whoever wrote this library is really good... https://github.com/msallin/...
Solves the whole headache of creating the initial SQLite DB...
Disclaimer: I should know what I'm doing but I don't. 😢
I'm a very experienced full stack dev (15+ years), but I don't know the more modern JS frameworks. I'm trying to learn React and I have a little project I'd like to do.
I have database (in both SQLite form and JSON form). I'd like to read from it, parse it and run various displays in a shared hosting environment (that doesn't have node). So webpack. And either an API to get the data or a React compatible SQL component.
But dagnamit, I cannot find a tutorial or example with this kind of set up and I can't figure it out. What packages do I need and what kind of config?
I genuinely thought this would be a traditional and simple architecture but I'm obviously mistaken. And I'm about to turn in my developer card because I'm clearly a stupid twonk.
Has anyone done this? Do you know of any tutorials or examples of this kind of thing? Is there somewhere else I should ask this question? Thanks anyway...5
Just spent 3 fucking hours trying to find out why my tests are failing. I'm mocking ef with an in memory sqlite dB as THE FUCKING. Net docs say to.
My code does a simple decimal comparison in a linq statement and returns bullshit. Why? Sqlite does not have a decimal type, it does some sort of BULLSHIT to convert it into some sort of text value.
I change all my models to use doubles instead of decimals and all my tests turn green.
WTF IS THIS SHIT. If it doesn't work don't tell me to use it. I expect better of the. Net docs. Wtf are they doing.3
Spending all day trying to install cockpit cms.
- bad permission.
*insert here all of swear-word you know"
Quick disclaimer, it is easily googlable, but no matter where I search, I can't find a solution. This is why I'm trying here.
Okay, so the other day, I was trying to install the node package sqlite3, and it spat out errors all day long from the node-pre-gyp native module and from the node-gyp native module. I am using the latest LTS (as of 5/10/2018), and I can't get any answers on HOW TO FIX IT...! Please HALP ASAP!12
I feel like a fucking god now!
We run a webshop and we are in contract with the national post office. Every time there is an update to their program I fear ahead of time what will be fucked up again.
After today's update we weren't able to open any shippment list we just saw a mile long error message. After the customer care couldn't figure out the problem, and the suggested solution might take up to 2days, and it is basically only a new customer file, i fired up my good old sqlite viewer friend, to chek if I am lucky...
Guess what! That shit is using unsecured sqlite dbs, so i've had no problem examining and even rewriting the values. So checking the logs and scraping the DB I've found the problem.
Apparently some asshole thought that deleting a service but keeping all of its references in other tables scattered around is a good fucking idea. And take it customer care, the new customer file won't fix shit, because it was in the global DB. I swear i am getting more familiar with that piece of garbage then the ones who made it.
On top of that the customer care told us, that if we couldn't manage to send the shippment list with the program we are not elligible for our contractual prices.
It is not enough that I had to fix their fucking shit program, they also "would like to charge us" because their pogram isn't working. What a fucking great service. (At least the lady on the telephone was friendly)1
Anybody know any other file based database technologies like sqlite besides sqlite? Struggled to find any if they exist, my google-fu sucks20
Embedded database is so lack of choice. SQLite, might be best, if you want stability / ACIDity.
Again, SQL means normalize everything, if I've ever want to index it...
Then, ON DELETE CASCADE? TRIGGER? Also, MANY-to-MANY kills.6
Mfw the CREATE TABLE statements in the SQLite database handler of my latest android app run perfectly first time
I started a project to practice and familiarize myself with SQL more and Entity Framework Core and prove how much I’ve learned from reading this book.
It was originally gonna be small program with a small database but over the course of me designing the database I thought of more features I could add. It’s been awhile since I’ve had a project and it feels good to have one.
Right now I’m only messing with SQLite but since the position I want to apply for asks for SQL Server I want to mess with that eventually.5
How many keywords are appropriate to put in a "skills" section on a resume?
Technically I've played with a lot of tech and stacks, and done tiny one offs, tutorials and independent projects but nothing that wasnt more than a day on any one of them.
Basically im fast at picking up a language and api and just rolling with it and getting something done, even without tutorials or tons of googling. Though I find myself constantly relying on manuals and reading apis.
Is this normal or should entry level be familiar with the api of something from the get go?
I see a lot of people say to game the system just to get your foot in the front door past the automated keyword filters and on to an interviews where the real requirements are listed.
But I'd rather not list under the skill section something I only used for all of ten hours in one or two sittings.
Also is it acceptable to list a "learning", "would like to learn/know more of", or "planned skill additions" section?
Also what do I add for extras? "Achievements"? "Volunteer work"? "Hobby projects?", "past times?"
Is any of this seen as necessary or well rounded?
If it is really just about the numbers I'll just go scrape junior and entry level positions and take their keywords and automatically fill out template resumes to automate applying.
Could even use SQLite to store the results and track progress lol.
I've never worked as a professional programmer, but it's the only thing I ever enjoyed doing for 12 hours a day.16
wow, its 4 am, nd i have been working with complex sqlite databases in my apps for near an year now.
And today at 12pm is my database paper and i don't know shit about the theory and technical terms in this xD
What local database you guys use??
I am searching for local db that also provide encryption for windows desktop application.
* found sqlite but most add-on that provide encryption are not free *11
This is just me throwing out my thoughts from the past few weeks.
edit: this is long
> Working on a C# project. its going well Its teaching me a lot about SQLite and file IO. I'm having a lot of fun with it, even the debugging as much I want to slam my head on the wall but I'm not asking for help so far and I'm very proud of myself because it feels so much better. like I don't mind asking for help but its so much more rewarding and I learn more from it.
> I need portfolio of software I can show off to employers and the current project I'm working on is the first programs in the portfolio. The place I want to apply to uses C#, but I still wanted a few other programs in other languages such as Python or JS just to show what I'm capable of.
> I was looking at what ASP.NET Core offers and it impresses the fuck out of me, and confuses me. The parts that confuse me, like for example the normal asp webapp is a very impressive hello world app. and it has so many different files and such but how or what do they expect me to add? how am I supposed to work with it? and if I delete any files I don't need (the premade js, bootstrap, jquery, html, and css) it produces errors because of the project files are pointing to those. and i know I can use the empty project (I do) but does that question my ability as a dev since I don't want to use it for my projects?
> On that note I love using Intellisense and debuggers and auto complete and I can go without them I just don't want to rely on them. idk I've just been a little more stressed these past few weeks.4
Are native Android apps easier to write now than like back in KitKat days?
I need a app that gets root permissions and reads a db file of another app (Yes my phone is rooted).
Anyone can give a gist, I forget do I need to create a Service background worker to do the DB reads... Or just need to send the op to a bg thread with a UI callback sorta like Node...
I did try writing a ReactNative app maybe last year just to try it out but can't seem to easily get root access... And the SQLite package is buggy, couldn't npm install on Win10...14
Apparently, while SQLite will happily let you write recursive common table expressions, it won't let you write MUTUALLY recursive common table expressions. This doesn't seem to be documented although I suppose you could infer it from the section I didn't read on how they work internally. Such a shame that I can't do this good and useful thing which I have good applications for.2
There are so many frameworks out there that already have their ways to connect the client application with the server one and then from the former to a Database, that I'm wondering how someone can build such server applications(for example in C++), then connect them to a Database (for example SQLite) and setup all the network configuration for a server running from home without getting mad2
just forgot to put string quotation(" ")
on query field with where clause and this small mistake wasted my 2 hours.
Hey, I am making xamarin android app with my friend, we are making registration, login (user) feature, and we're looking for database for it, is SQLite good for it? Is it safe for that?1
Recently I had a task from my university to build some DB with forms using MS Access.
Despite of me constantly thinking that I wold accomplish this using Python+SQLite+Some GUI much faster, I've completed.
And I've got only one question left: why the hell proprietary product with giant company behind has such a terrible UX?
It' really painful to use.
You know what really grinds my gears? Java libraries that use native libraries when they could have easily done their task without them.
I’m looking at you Couchbase Lite. Use H2, not SQLite you dumb shit. Be smart like Nitrite.
Looking for a Framework or language that has:
- multi-platform (Windows + Android minimum)
- Easy to design GUI
- Can use file databases like SQLite
- Can use serial, BT, Wi-Fi to send-receive data.
I already used Python + Kivy but I think there must be easier frameworks for this...21
MySejahtera is not a good appliaction at all! They just use Sqlite or Shared Preferences in the app for keeping the data local. (Just local?) As soon as you clear cache or data, The user no longer exist! Like wtf ?
So I decompile the app and review the source code, the code is not even properly obfuscated(That's why I can read it). There's a part of the code on a for loop went
for (int i = 3; i < array.length(); i++)
for (int j = 2; i > array.length() *2; j ++ )
Which is unacceptable!
First , why nested for loops?
Second, instead of declare 'array.length()' multiple times why not declared it global for once?
No wonder the initial state of the app is buggy as hell.8
And now I'm gonna use my entire day to restructure. an application (Built in Java with swing and jdbc to connect to mysql ),and instead use Java with sqlite and swing1
sqlite lets you violate foreign key constraints on insert.
so you then can't delete the row you added
which has absolutely no child data so it shouldn't be preventing you from deleting it.
https://learnbchs.org - The web framework consisting of OpenBSD, C, httpd and SQLite.
What do you think? Not sure if I should call C-webdevs insane or genius (maybe both).
I think the code will either end up very secure or with more severe bugs than any PHP website ever had. Please talk me out of trying it.7
Okay, i have a question.
I am a real Noob when it comes to Java programming. I am trying to establish a database connection between my program and a sqlite database. I have everything ready:
- The Model
- The View
Now the problem i am having is defining the DBController that establishes the connection. And i have no idea how to start?!
Please help me :(
favourite/recommended database IDEs/tools? I'm looking to put more time into a hobby project using mysqlite. I only got datagrip, mysql workbench and DB Browser for SQLite on my list so far3
Cisco Jabber is a load of shit. I don't really know how to get chat logs with people I haven't added to contacts from the UI. So I just open the SQLite database it saves locally to read. Every single IM entry contains a ton of HTML/CSS to keep formatting. Who writes software like that!1
Anybody, who wishes to collaborate on writing Ramda solutions for SQL like queries, I have created the project (SQL queries, SQLite database, json data files) here - Ramda-SQL-Equivalent GitHub project (https://github.com/ajit555/...).
Please post the questions in "Issues" section and hopefully would get some solutions via pull request.
If not sending pull request, please post the solutions as issues referencing the file name.
Is there a portable DB format like sqlite but stores data like Mongo.
Each record contains key value pairs.
I guess I could install Mongo again... But kinda want to play with the data first. Pulls from a web api
I guess other alternative is to just save the json responses to disk in separate folders and files for now...
And abstract the DB layer behind an interface6
Is it a good idea to code my Android app keeping sqlite in mind before actually migrating to a noSQL version?
The primary reason for doing this is not having to deal with APIs or server side coding and also faster testing and prototype development.
Any ideas or suggestions?7
Does anyone know about an embedded document store database for Go? Currently I'm using SQLite but now I want to implement more features for which I prefer a document store database.1
Fvck! I can't add primary not null autoincrement in existing table on sqlite! Waste hours trying! Damn.1
I made a self-medication system for pharmacies for over the counter(non prescription) medication with Java with swing and mysql and then I shifted to Java with sqlite and swing.i don't even know if that's a good or even legal thing to keep working on.
ORM feels like, I can do better than that, with more predictability (like naming, table creation, and stuff).
The only pro, is hopes for inter-dialects interop (SQLite-Postgres-MySQL-MariaDB).
OK, I also want SQLite-MongoDB interop, because of the cheap price; but this is difficult.
Someone answer this question.
I'm stuck on this.
I've tried almost everything that's possible
Why? Why does Eloquent with SQLite only fetch attributes as strings? I spent at least half an hour debugging, I just want to set up a local test DB and now I have to run a whole PostgreSQL instance3
Any way to run some python code in android without losing my mind !? It is just a code which queries a simple api once a minute and logs it into a sqlite db. I want to use my phone as a substitute for a server instance, cos i dont have the monies to buy one..😬.. SL4A aint working.. P4A webview isnt working for some reason.14
I thought I had to VARCHAR in non-SQLite RDBMS. I was wrong. There is TEXT.
1. PostGres seems to work better with TEXT.
2. There is an ORM that forces VARCHAR (255) by default.
3. But you can go over the limit without throwing errors.1
How does FS-based locking,
Eg. What sqlite does, work on the inside?
I'm working on a file-format for storing binary data and I want it to be safe for concurrent use.2
Sqlite.sqliteexception:no such column:Timestamp (code1):,while compiling : SELECT * FROM NOTEs ORDER BY Timestamp
I am trying to get the date and time on each entry of note..17
I try to do some C# on VSCode and i dont understand why my nuget package won't working ... I just try to install sqlite . 😔1
