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.

🤓 There was a fantastic #cardano metadata workshop hosted by @JeremyFirsterCF, @benohanlon, Alan & Mel.

💡#Metadata is key part of the ongoing #Goguen release & is already running on the main net. 💪

Below is the recap of their conversations 👇 $ada #crypto #fintech #dev
2/n

What exactly is transaction metadata? 🤔

1⃣ Details on "The Transaction Story"
2⃣ User-specified information that is added & stored on the Cardano blockchain.
3⃣ Secure record of immutable and authentic on-chain data.
3/n

How is metadata generally used? 🤔

1⃣ Certification & validation of particular information
2⃣ "Tell the Story of a Transaction" - $ada transfers
3⃣ "Create a Story" that has a permanent record - standalone transaction for adding data

==== Caching ====

caching is the process of storing data temporarily. a cache generally lives for a relatively small amount of time. examples: browser cache, DNS caching etc.

reasons to utilize caching: 👇
(thread)

#cache #web #dev #CodeNewbie #100DaysOfCode
* save bandwidth (and reuse resources)
when using cache mechanism in client-side applications, it ensures that cached files won't be downloaded again from the server.

* save processing power
when writing algorithms, it could be optimized using a caching mechanism...

2/n
...caching would help add memorization to that algorithm, enabling it NOT to repeat the same calculations again and again.

* save time
we all visit websites mostly by domain names(and rarely using the IP address). having cached DNS records would let the resolver use...

Thread.

So of you may know I often point out the limitations of #Blockchain.

But I was curious if a current #Cryptocurrency or other type of hApp was built on #Holochain, could some of that data be populated onto a blockchain?

The only reason I could think of doing so would
be if a current #blockchain project wanted to remove the inherent blockchain issues, Scalability, Consensus, Congestion & Cost but still be able to retain their brand or "chain".

#Holochain mitigates all of these issues with unlimited scaling, the options of zero TX/RX fees it
would make sense for some of them to migrate to a cutting edge architecture that puts them in the new generation of #cryptocurrency while still being able to maintain their roots.

So I spoke with #Holochain lead #Dev @helioscomm & Paul advised that yes this is indeed possible.

Have you ever heard about Code Smells?

Learn more about how to avoid them to develop better solutions! 🧵THREAD 🧵

#100DaysOfCode #Dev #CodeNewbie Image
"If it stinks, change it"
A code smell is a piece of code that goes against good practices or fundamental design principles and therefore negatively impacts the quality of our solution.

Here is a list of code smells and how to solve them:
1) Long Method Implementation
Methods that make you scroll just to get an idea of what is happening?
You are most probably missing some abstractions and decomposition. Delegate responsibilities to corresponding objects/classes and create smaller methods that make sense together.

Highrise is a 30-person fully remote team. I'm sharing our Slack best practices to stay connected without distractions. Thread: 1/12
We thread absolutely everything. We work in 7 different timezones, and nobody wants to wake up to a channel with 100+ messages. Threads reduce message clutter by 10x. 2/12
We use an #update-daily channel to share what we did yesterday and what we'll do today. We also share when we hop offline or online, which makes our virtual office feel "alive". 3/12

🔥🔥🔥 The #1 Recursion (Syntax) Twitter Thread

This thread will demonstrate an easy way to write recursive functions

The recursion will so be compared to a for loop for familiarity

Tail Calls and Performance discussed later, Syntax Only!

gist/theme at end 👇

#javascript
Step 1: Create your iteration variable(s)

In recursion, it can be easier to set a default value. Pass `i` again when calling `loop` on the `return` line

#javascript #code #dev #es6
Step 2: Add a break condition

Like a for loop, add the break before you write your code. This will prevent infinite looping.

Notice how the for loop is a "continue" and the recursion uses a "break". That means the condition must be flipped for recursion

The secret source for delivering value in form of software at (enterprise) scale? Option 1: the Thanos Method (get rid of most people) - Not recommended but effective for sure.
Option 2: create and maintain an immune system made of strong engineering culture (includes #ethics!!) AND platform thinking (for synergy effects & North Star). This is the option I do consulting at: Strategic Software Delivery. #devrel #dev #experience #SoftwareEngineering
The immune system is a passive force to allow customer centric thinking, allow experiments on all levels. It frees up busy minds and let’s you focus on delivering value to customers. Because it is a passive system, it is easy to overlook, but it makes all the difference.

So I had my first #Police vs #Dev Encounter today.

Stepped out of School to run an errand and on my way back I was stopped.

We had the regular back and forth on whether I was doing "work" as they called it.

Questioned me about my phones and laptop also

1/11
Showed them my school ID which had Computer Sciences boldly written on it and I told them I needed a laptop for my school activities.

They searched me, searched inside my trousers, hoodie, shirt and bag.

They then began questioning me about homosexuality and cultism 😭😂

2/11
Next thing, they wanted to search my phones and PC. I opened them all for them to search.

Well I use Linux so they couldn't operate my PC, they also couldn't operate my Pixel because the pixel doesn't have the regular back and minimize buttons like the regular Android.

Question for #dev community: I have a Github account with many cloned Cambridge Analytica / AggregateIQ / SCL / etc relevant repositories (none of which include the AIQ Git*L*ab repo data). The intent is to preserve GH repos which are/were published publicly by the originators.
That international-investigation-relevant account has been flagged by Github and been made "hidden" from public view. Their reason is that I have a 2nd Github account (tied to my employment [which I believe should remain separate]) and Github only allows one account per person.
Here's the question: Given the situation, am I stuck with Github's decision to hide the preservation account from public view? Does anyone have experience appealing this designation? Github is, most likely unknowingly, censoring a resource that could help many investigations.

When you have two systems that need to communicate, the default for 90+% of companies is to use a shared database. (thread) #dev #programming #architecture #softwarearchitecture
Most never move off of this model, but it has disadvantages that go along with the ease of sharing data. Applications lack encapsulation and cannot adapt their data designs to suit their unique requirements.
Usually the next approach is to treat applications just like components, with exposed public APIs. However, this can result in increased down time since direct API communication between applications means if any is down, the whole thing is down.
