Sometime in @angular app template try to load data which hasn’t been calculated yet and as a result view is empty because data is retrieved after the view is rendered.

To solve this issue lifecycle hook like ngAfterViewInit() comes handy. You may trigger your data retriev call in this hook.

A thread on how I managed to encrypt and store a video using #Flutter

Scroll for links, code snippets, and my general thought process...
Recording and saving videos locally isn't too difficult.

Dependencies:
- camera
- path_provider

#flutter #android #s21 #video #coding

Below is the code for getting a file reference:

Created with @carbon_app   /// One call to get a file reference, set temp = false to
Encryption on the other hand is a foreign language to me. From my research, I learned that each user needs an #AsymmetricKeyPair that can be used to #encrypt and #decrypt data.

To generate these, I used the rsa_encrypt package.

Sorry for the typo in the pic above. Forgot to add comma after a element so it should be like this: 👇👇

In #javascript array.some() determines whether the specified callback function returns true for any element of an array.

A function that accepts up to three arguments. The some method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value true, or until the end of the array.

Dear #deverlopers or #codenewbies if you are confused about Promises and Observables then follow below thread.

▶️ Observables vs Promises
Both Promises and Observablesprovide uswithabstractions that help usdeal with the asynchronousnatureof our applications. However, thereareimportantdifferences between thetwo:
1️⃣ As seen in theexample above, Observables candefineboth the setup and teardown aspects of asynchronousbehavior.

2️⃣ Observables are cancellable.

Just listened to the @IndieHackers podcast. @csallen spoke with @dvassallo. This quote struck me: "As soon as something inspires me... I tend to do it almost immediately, at least I’ll start." So I'm going to live-validate an idea right now. Join in with ideas/input. Thread 👇
My hypothesis: Users of SaaS apps often need to upload data from flat files (csv, excel). Designing and coding this feature is really annoying - multiple file-formats, complex error handling, unclear UX - and a source of support.
My initial product idea is a service that handles file parsing, customizable validation, generates a template for users to fill out, and provides a UI with error-correcting feedback. Probably in the form of an API + SDK.

#BandaDaily #1:

When #coding something, always approach the problem iteratively.

That means that as #developer you go through roughly 5 stages:

1. Make a straightforward solution
2. Cover edge cases
3. Improve the performance
4. Improve the design
5. Reduce complexity

🧵👇
1. Make a straightforward solution

It's the basis of your work: it's rough, potentially inefficient, and may not work in the edge cases.

Copy/paste here instead of creating complex reusable components.

Here's the goal to create something that actually works, but not perfect.
As a junior engineer, you should be able to come up with at least one such solution, after thinking about the problem for a while, researching, and discussing with more experienced engineers.

If you still can't, the problem requires more expertise than you currently have.

Have had a chance to read a great article by @dangoslen:
levelup.gitconnected.com/my-biggest-mis…

The lessons he learned at the beginning of his #SoftwareEngineer career are quite similar we've encountered on our path and put as principles for junior #developers.

What are those principles? 🧵
Principle #1: Don't listen to your ego — talk to your team

Stop caring about your thoughts of what other people might think about you. It shouldn't matter to you.

Always talk to your team when you are in trouble, share your thoughts, get answers/help, and continue growing.
Principle #2: Be braver — say (nonsense) aloud

A similar one, but still quite different: if you get an idea or thought - say it aloud during tech meetings, discussions, one on ones and so on.

Doesn't matter how bold it is - don't hold it back. Say, get feedback, and move on.

Ever wanted to learn coding but don't know from where to get started...

This thread 🧵 might help you.

#100daysofcode #programming #Coding #CodingTips #Thread #StartLearning #CodeNewbie @CodeNewbies
1. What you are interested in???

Do you want to create a website, or wanna deploy your apps on #Google PlayStore or #Apple @AppStore. Or you are learning just for fun...

Ask yourself this question before starting with actual coding
2. Choose your language according to your needs...

For eg for becoming a Front-end developer you need to know HTML, CSS
For making Android apps you need to learn Java
For making a completely working website you need to know JavaScript, HTML and CSS

Please help us welcome our next curator Darryl Takudzwa Griffiths. @BlaqNinja completed his Bachelors Degree in Computer Engineering at DUT, graduated in 2011. Due to struggling to find suitable employment he went on to study multiple certificates from bodies such as Microsoft.
He has certificates in N+ (Computer Networking), A+ (Computer Technician & Technical Support), Certified Ethical Hacking V7 (CEH v7), Offensive Security Certified Professional (OSCP). Sadly even with these, he could not secure his desired post so in 2016 he moved to USA.
Darryl was able to secure a job in a corporation that owns casinos as a system analyst & security architect. Within the same year he embarked on a Masters degree in Robotics & Artificial Intelligence Engineering. In 2017 he resigned from his post and started his own company...

You can't learn programming without self-exploration and there is no better place to do this than documentation.

W3 schools and mdn are pretty famous but probably you haven't heard about DevDocs(a complete guide).
