Dear fellow devs out there. I am looking to compile a list of resources for any java developer to get started with saas development. If you can pass any resources, that would be really helpful. Also, I am wondering is there any framework/project like the below exists in the Java ecosystem?

Accomplishing That *One* Thing Each Day

_This post was originally published on June 24, 2020 on [my blog] (https://alexlsalt.github.io/blog)._

Random thought: I feel like today is a birthday of someone I know well but I can't remember whose, so if it's your birthday, happy birthday!

Wednesday morning, folks! I had one of those great wake-up-early-naturally kind of mornings, and they just feel so good. I took little Nelson outside, then dug in a bit to my latest read: Atomic Habits by James Clear.

It's been on my list for a while now, and it finally became available to me on my Libby app, so that's fun.

Today I'm planning on recording another podcast episode (this evening) and signing up for podcast hosting (yay!).

I can't even explain how much of a game-changer it's been in doing just *one* thing each day to push myself forward on whatever my current goal or project is.

Intuitively, I think we want to try to get as much done as possible each day, but I'm finding that this all too often leads to burnout and apathy.

Doing just one thing each day and being satisfied and proud of myself is the way I want my life to be, always, so I'm practicing that now.

(See also: [Designing the Life You Want to Live] (https://dev.to/alexlsalt/designing-the-life-you-want-to-live-2gg4))

So, podcast eppy tonight, and then I'll probably do another hour or so of learning about and implementing APIs in my JavaScript course on Udemy.

Other than that, we're headed to our fave swim spot today and I can't wait to watch my little sausage, Nelson (dog), go ham for the swims. Cheers!

Thanks so much for reading along! [Now let's be friends over on Twitter >>] (https://twitter.com/alexlsaltt)

P.S. I'm on the cusp of launching a brand-new podcast! Stay up to date by [signing up for the newsletter here >>] (https://www.ladiescodecollective.com/)
How to Retrieve Lost Pictures from an SD Card
Published: 2020-06-24 07:11:00

SD cards or Secure Digital cards are becoming a more common and useful device to store our valuable data. These compact storage devices can be seen everywhere, ranging from our smartphones to the cameras in which we record our vacations. This is why <a href="https://recoverysquad.com.au/service/solid-state-drive-ssd/">SD Card Recovery Melbourne</a> services are essential to ensure that your precious data is intact and safe in case anything goes wrong.

One of the most important reasons why more and more people are using SD cards is that they are tiny and small. These devices can store up to 128 TB of data at the utmost top end. However, the SD cards that most people use on their phones and cameras usually max out their storage capacity at around 512 GB. 

Like all other forms of physical data storage, SD cards are not perfect. If you have a damaged SD card at home, it is probably due to one of the following reasons.

<h2>Reasons for SD Card Damage</h2> 

1.Physical Damage
2.File System Corruption
3.Accumulation of Bad Sectors on the SD Card 
4.Improper Insertion and Removal of the SD Card
5.Interruption of SD Card during formatting 
6.Manufacturing Defects or Damage to the SD Card during shipping
7.Virus or Malware Infection
8.Accidental Deletion of data from SD Card

In case your SD card does malfunction, and you have a lot of essential data and information stored on it, there is no need to panic or be worried. Generally, this damage can be undone by a professional Micro SD Card Recovery Melbourne. Using professional tools and software, experts have been able to recover data that has even been accidentally formatted by users mistakenly.

<h2>Here are some of the best ways to recover the data in your SD card</h2>

<b>Identify why the data is inaccessible.</b>

Two of the most common causes of data loss in SD cards are accidental Deletion and accidental formatting of the media. If this is the case for you, disconnect your SD card and stop using it. This maximizes your chances of recovering the data you might have lost.

<b>Launch Data Recovery Software:</b>

Ensure that your laptop or PC has enough space to save all the data that might have been on your SD card before starting the data recovery software. Using the SD card Recovery Pro Software you should be able to recover your data comfortably.

<b>Launch a full SD card analysis:</b>

This software allows you to complete a full scan, and identify all the recoverable files, make a copy of these files. All the data that can be recovered should be backed up during this process. This is done so that you can ensure complete data integrity.

<h2>Conclusion</h2>

One of the most important things to take note of when you are trying to recover data in your SD card is that there might be situations where a specialist is required. Ensure that the specialist is experienced and has performed operations like this a lot of times. The functioning and safekeeping of your data are paramount, so always be mindful.
How to achieve ARM cross-compilation on macOS

> This article originally comes from [lewuathe.com]( https://www.lewuathe.com/how-to-make-arm-cross-compilation-on-macos.html). Please visit there too if you find this interesting.

Cross-compilation is occasionally troublesome. It often requires us to install additional toolchain to get it done.

Now, I found I needed to compile my source code for the Arm architecture machine for [Mbed application](https://github.com/Lewuathe/mbed-sample). I do not have any idea how to install the toolchain for Arm compilation. Thus this is the post to describe the fastest way to prepare the toolchain for the cross-compilation for Arm.

# Xcode Compiler

Please ensure to install Xcode first. Xcode contains the first compiler sets, such as clang.

```
$ xcode-select --install
```

# Arm Toolchains from Homebrew

You can install Arm GCC toolchains by using Homebrew. There are two options.

- [osx-cross/homebrew-arm](https://github.com/osx-cross/homebrew-arm)
- [ARMmbed/homebrew-formulae](https://github.com/ARMmbed/homebrew-formulae)

There is no difference between these two distributions. They use precisely the same package internally. You can use whichever you want.
For my Mbed application, I choose the second one.

```
$ brew tap ArmMbed/homebrew-formulae
$ brew install arm-none-eabi-gcc
```

You should be able to find the compiler eventually. The following tools are installed in the local machine.

```
$ arm-none-eabi-gcc
$ arm-none-eabi-g++
...
```

It looks like they are GCC for Arm architecture. I believe it is the easiest way to prepare the Arm build toolchains in macOS platform.

Thanks
Recover lost data without burning a hole in your pocket
Tags: database
Published: 2020-06-24 06:29:42

Losing data from your hard drive or laptop is easier than people think. All it takes is one click, and all the stored data of the person might be wiped clean from the device. This can be a big problem as some of the files can be necessary for professional purposes, while others may hold sentimental value. Either way, it becomes crucial to retrieve the lost data as soon as possible to avoid losing it permanently. Some people think it is an expensive process to recover lost data, but that is not the case in all the situations. Here's how you can retrieve your data without burning a hole in your pocket.

<b>Recovery software applications</b>

You can set and think about any service or help that you need, and there is probably an app made to help you out for precisely that. There are several software applications recommended by <a href="https://centuryitc.com.au/our-services/hard-drive-data-recovery/">hard drive recovery Melbourne</a> companies and experts. All one has to do is install the apps on the device from which data has been lost and follow the instructions as given by the application. It is the most inexpensive yet convenient way of retrieving lost data from a hard drive. These apps might, however, not be able to recover data in case of severe data loss.

<b>Manual retrieval</b>

There is nothing like getting your hands dirty and doing your work by yourself. The best part is you are in control of the entire process. Several qualified IT experts and professionals have narrated the retrieval of lost data in blogs and videos. This process may take some time to understand, but it is most suitable when the data is not sensitive, and the user has a basic knowledge of the workings of the device. And as you can guess, doing things yourself saves a lot of money. If you are unfamiliar with the device, it is better to abandon all thoughts of manual data retrieval. 

<b>Hire inexpensive experts</b>

Many people are under the impression that professionals charge too much for data recovery, but this is not true. If there are a lot of essential files in the hard drive or the device, it is better to seek help from a professional to avoid the risk of damaging the device further. There are numerous service providers online, and you can seek out the genuine ones whose charges fit your budget.

It is safe to conclude that data recovery is not cumbersome as most people make it out to be. If you pick the right kind of service providers, they do not charge exorbitantly for a simple recovery job. All you have to do is put in some effort to find the right people for the job, and the rest is a walk in the park. So the next time you lose data from your hard drive, get professional help instead of risking your data, and wasting your time. Remember, almost no data loss is irrecoverable if you have the right experts.

Setup a Linux Dev Environment on Windows 10
Tags: wsl, windows
Published: 2020-06-24 06:13:44

Also published at [my CollectedNotes](https://collectednotes.com/tbeseda/setup-a-linux-dev-environment-on-windows-10).

Largely sourced from the official [Microsoft](https://docs.microsoft.com/en-us/windows/wsl/install-win10) [docs](https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel).

## Win 10 Build Requirement

You must be running Windows 10 build **1904** or higher (run `ver` from cmd.exe to check).

## A Fresh WSL Install

From PowerShell with Admin access (right click PowerShell or a PowerShell shortcut and *Run as Administrator*)

1. Enable WSL, run: `dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart`
1. Enable "Virtual Machine Platform", run: `dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart`
1. Download and install [WSL 2 Linux kernel from Microsoft](https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel)
1. Restart Windows for good measure.
1. Set default WSL to v2, run: `wsl --set-default-version 2`
1. Download your favorite Linux distro from the Microsoft Store (Yes, really. I searched for and installed "Ubuntu".)
1. Launch and set up Linux by running `wsl`

And you're off to the races! From here, I'm able to install Node.js, Typescript, Yarn, etc.

## Upgrading from WSL 1

*Instructions a work in progress...*

1. Update to WSL 2
1. Set v2 as default WSL
1. List existing distros
1. Upgrade existing distro
1. Remove unwanted ("Legacy") distro with --unregister

My roller-coaster ride on a project

## **Novelty Detection using CNN on UCSD-PED dataset**

## Demo image
![demo_io_69](https://dev-to-uploads.s3.amazonaws.com/i/qyj80ozh79racuzv5vh9.jpg)
 

## Link to Code:
Its around 11GB project, so I have not uploaded the code anywhere.


## How I built it 
It was a cool experience to work on an unsupervised machine learning. But, sometimes I felt it was very hectic. I read many papers about the unsupervised models, novely detection, anomaly detection. Also found some same implementations but on other benchmark datasets like MNIST and CIFAR-10. So, I opted the UCSD-ped dataset for my project. I needed a GPU for my cuda functions to work. But without it, I started the project, used my 12 gig ram to train without the cuda. I thought I was dumb choosing this project. But later, my counselor helped me and provided me the access to the university lab resources. And this way, I completed my project on a roller-coaster ride. 

## Additional Thoughts / Feelings / Stories
Whenever you feel like dropping any idea of project, talk to someone of the same field. Maybe he/she cannot give you better ideas to optimize/upgrade your project but you might end up with path leading to solution of your problem.
