Business Problem without a Solution?

Stefan Wuthrich — Sun, 20 Nov 2022 08:48:06 +0000

Starting in January of next year, I will have more time to work on my own projects. To get in contact with real business problems, I launched the Free Solution Deal on https://freesolutiondeal.com, where business owners or managers can participate to get a chance to receive a free software-based solution that solves your business problem.

The Deal Conditions

You have a problem in your business that is not resolved or not well resolved, and can imagine that there could be a (better) software-based solution.
You must NOT provide or have any solution in mind for it. You give me a clear description of your problem and what company you have or are working for.
I will preselect some problems until end of 2022 and then start doing interviews if you are part of them. During this process, I will learn more about the problem and try to propose some rough solutions.
I will, after that phase, select a max of three problems where I define a detailed solution which I then present to the “problem owners”
I will start to build the proposed solution If at least one of them agrees that they can resolve the problem and deliver them as a Software as a Service product.
You as the selected problem owner, will get the solution first, 100% free, for a lifetime, with all initial and future features and exclusive support through me. *You will get a contract with my US company assuring the usage right for your company

I launched my 7th Job Board, now for Java Jobs

Stefan Wuthrich — Thu, 11 Aug 2022 09:44:11 +0000

Beginning of 2019 I launched fullstackjob.com as a single-tenant Job Board for Full Stack Jobs.

After that I did a refactoring and built the engine to be multi-tenant, to be able to run multiple job boards with same instance of stack (Go based API/Webserver, Vue Frontend, ArangoDB)

Beginning of this year I did a complete new multi-tenant engine which is not more using Vue, but SSR plus a bit of Alpine JS to improve SEO. (btw I continue to use Vue 3 for other software projects, where SEO is not so important)

Since then I launched more 5 Job Boards:

And now, Java Job Board javajobs.pro is launched

The new Java Jobs Board is ready to find Java related Jobs and hiring Java developers.

You can of course also find Remote Java Jobs

Thank you to over 9000 #golang followers

Stefan Wuthrich — Mon, 11 Oct 2021 04:34:59 +0000

Yesterday I reached 9000 Followers for my @golangch Twitter account.

Some asked me, how I reached this number.
Well, there is no strategy or trick. I tweet since Jan 2017, as a human (there are a lot of bots out there...) about Go related stuff, mainly libs/packages/apps written in/for Golang and interesting articles about Go.
Rarely I use it to promote Golang Jobs from my Golang based Golang Job Board

Thanks to all Gophers following me.

Remote Jobs for Javascript, Go, Python and Fullstack Developers

Stefan Wuthrich — Mon, 19 Jul 2021 08:26:25 +0000

We know it all...

Since Covid 19 changed all our lives, Remote Jobs offers are growing, as many companies realized that this mode of work works fine for them and can attract new developers out there.

I have run now about three years four developer-related Job Boards, which have since begun a Remote Filter for Job Candidates and, of course, those options for companies adding Remote Jobs.

Here the boards:

Remote Fullstack Developer Jobs
Remote React Jobs
Remote Javascript Jobs
Remote Python Jobs
Remote Golang Jobs
Remote Rust Jobs

How to use Google Places API with Caching ( complete Golang/React Source )

Stefan Wuthrich — Sat, 30 Jan 2021 08:36:42 +0000

This day's I started with a new side-project named ProdutoMania

This project's main feature is to find products from my home country at the place I'm currently staying.
So I need a selector of location and to use Google Place/Maps API is on the hand.

Now, this API is paid as soon usage is getting above a certain amount.

This can be risky if you do put the queries as autocomplete/typehead directly fetching results on the client-side. So I decided to call backend API with a search term and the handler on the server-side take control of the usage of the API.

This opens the possibility to do throttling (not part of this post) and caching. Caching makes much sense, as locations do not change every minute, hour, not even days.
There is a max period of time allowed by Google for caching, at the time of writing this post it was 30 days.

To build the API I use:

Go with Chi Router (could also be done without, just using net/http standard package)
Google's official Go Client for Google Maps
Caching Middleware victorspringer/http-cache

Victor Springer's Caching Middleware is a perfect fit to cache RESTful API's. It supports memory, Redis, DynamoDB, and other storage for the cache.

here the config part of the story:

// Cache Middleware Config
memcached, err := memory.NewAdapter(
    memory.AdapterWithAlgorithm(memory.LRU),
    memory.AdapterWithCapacity(1000000),
)
if err != nil {
    fmt.Println(err.Error())
    os.Exit(1)
}
cacheClient, err := cache.NewClient(
    cache.ClientWithAdapter(memcached),
    cache.ClientWithTTL(24 * time.Hour),
    cache.ClientWithRefreshKey("opn"),
)

Then I define the handler and routes applying the middleware:

// Cache Google Place API calls
hLocation := http.HandlerFunc(handler.GetLocations)

r.Route("/", func(r chi.Router) {

// location autocomplete
r.With().Get("/{term}", CacheClient.Middleware(hLocation).ServeHTTP)
})

On Frontend Side I use:

React with Webpack, using my own React 17/Webpack/ Boilerplate
Downshift as a flexible Autocomplete/Dropdown Component
Debounced-fn Package

The Debouncing is important for the typeahead function to not call API on every onChange triggered by a Char. It also does not make sense to send just one char to API.

here the useLocation Hook/Service part of code:

export function useLocation() {
  const [{ isLoading, error, data }, dispatch] = useReducer(
    reducer,
    initialState
  )
  const fetchLocationResults = debounce(
    async (searchString) => {
      if (searchString.length > 2) {
        const locationUrl = `http://localhost:9090/${searchString}`
        dispatch({ type: actionTypes.FETCH_REQUEST })
        try {
          const response = await axios.get(locationUrl)
          dispatch({
            type: actionTypes.FETCH_SUCCESS,
            results: response.data,
          })
        } catch (error) {
          dispatch({ type: actionTypes.FETCH_FAILURE, error })
        }
      }
    },
    { wait: 400 }
  )
  return { error, isLoading, data, fetchLocationResults }

Have fun (without high invoice from Google :-) )

Help me do a Go Newsletter you will like

Stefan Wuthrich — Fri, 15 Jan 2021 04:49:53 +0000

I’m Stefan, the maintainer of this new Go Newsletter.

I started with Go about 5 years ago, when in the company I work for, our CTO showed me the hefty stuff he codes in Go and explains why he chooses that company is using Go. ( thank you for that CTO, I know you read this 😄 )

I’m not working as Dev in this company, but product management, but code since “Shining” and before Acoustic coupler’s (google about….) entered in the IT-sphere. I always want to be “state of the art” with coding, that Dev’s I work with can not tell me any story, and I can do Sideprojects, like the Go Developer Job Board.

Since 2017 I tweet daily about new or update Go Libraries, go-based open-source software, and have on @golangch over 6300 Followers.

Now I start this Newsletter to have a way to write a bit more about the interesting stuff I find when I schedule my tweets via some other side-project, I do, plus use this channel to get to some discussions with the Go Community.
NOW… What you need to work (please 😄 )

First, please tell me in the comments on what frequency of newsletter you prefer
bi-weekly, tri-weekly (uncommon, but why not), or monthly.

Second. What are you most interested in:
a) Go Packages/Libraries (to use in your projects)
b) Go-based tools, open-source software ( to use and/or to study code )
c) Golang related content, like tutorials, blog posts.

Please subscribe and comment here:
Golang1 Newsletter

Thank you and until soon
Stefan

What I developed over the last months weekends

Stefan Wuthrich — Sat, 05 Dec 2020 05:40:20 +0000

Recently I started working on a new project called nboarding.com. This is a tool to help founders, owners, or team managers onboard new people and delegate tasks efficiently.

Before that, I built omnited.com, a kind of JIRA to manage tasks and projects. I wrote about that in a post I built my own little JIRA

Before that, and I'm now back working on that one, I built Kunvenu Social Media Posting Tool for Teams.

It allows the admin to set up teams, invites team members, and then share the social media accounts (Twitter, Facebook Pages and LinkedIn) with teams.
Team Members can then write posts and schedule them to send out to multiple social media accounts in one shot.
I use this tool for posts of to #golang Twitter and Facebook accounts and also for Developer Job Posts for my "oldest" project Fullstack Developer Job Board

Learning from these experiences I will now introduce new features for kunvenu.com like cloning of posts, more metrics, probably more channels like Telegram Groups.

Stay tuned

Ask me anything: Daytime CPO, Best-time Maker

Stefan Wuthrich — Mon, 23 Nov 2020 05:46:08 +0000

I worked in different Roles since I started to work professionally with Software Development (without any degree) over 25 years ago. From "Web-Master" to CTO/CEO, as an owner, employee, and freelancer, from Switzerland, Brazil, Serbia...

Well, AMA, if you believe me, that today I don't work with Cobol and Pascal ;-)

I built my own little JIRA alternative

Stefan Wuthrich — Fri, 11 Sep 2020 02:27:47 +0000

Since I built my job boards ( eg https://fullstackjob.com ) it's now over a year passed and I also built my social media post/schedule tool Kunvenu which I daily use for my #go posts via @golangch, reaching 5000 followers about 2 weeks ago.

What I worked on over the weekends for the last 4 months is my own Project Management Tool, named omnited
It's a Project and Task management, where you can define eg what kind of Status, Priorities and Issue Types you want (on the project, folder, and list level).

You have a List of Peoples working in your company (where not all must be Users) and can invite new ones via the app.
As a User or Project Manager, you have now 2 different types of Issue Views, List, and Board.

I built the tool with the following Stack:

Go backend, Chi Router, own auth/authz implementation
ArangoDB and Redis for data
Nsq for queueing
Frontend Vue, Vuex, Bulma (with Buefy components)
Hosting on own Server with Rancher 1.x/Docker

I use the tool now for the planning of my new project I started last weekend, which is named nBoarding and is a tool that helps founders and mainly small business owners and team leaders to onboard new staff members or freelancers with automatable predefined workflows.
Here I will use the first-time Nuxt for Frontend. Let's see. SSR is cool, but has a cost :-)

If you want to be my Beta Tester I have a Lifetime Deal running on https://omnited.com

Cheers
Stefan
