Ok, so the golang language does not exactly have the word “while” in it. Anyway, the do-while and while-do loops can be easily implemented with a for loop. The main difference between the do-while and while-do is that in the…

Python – Enumerate Lists in a Loop
Plenty of times, when you are looping with a for-each loop in python, you somehow realize that you need a counter. Then you most probably write something ugly like this one:
|
1 2 3 4 |
a = 0 for count_value in my_odd_squares: a = a + 1 print(f'({a}, {count_value})') |
Why is this ugly? Mainly because the next…

VBA – Option Compare (Text || Binary || Database)
Option Compare in VBA is the thing, that will save you ugly stuff like this one:
|
1 2 3 4 5 6 7 8 9 10 |
Sub Testing() Dim userInput As String userInput = InputBox("What is decimal 4094 in hex?") If UCase(userInput) = UCase("ffe") Then Debug.Print "You have correctly written " + userInput + "!" End If End Sub |
Yup, it is a bit ugly, using UCase to compare all the time, between small letter text and big letter text. So, if you…

VBA – Get Substring Between 2 Substrings – Locate value of Nth XML
Getting N-th string between two substrings might sound a bad idea, until you do not need it. And with VBA, you better have something prepared. So, imagine the following XML (from this article here):
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |

Python – Parsing PDFs with Tika
Reading from a pdf is actually quite an easy task with Python. If the PDF is of course “readable”, e.g. made from a word processor. The first thing to do is to install Tika and Java:
|
1 2 3 |
pip install tika <em>conda install</em> -c conda-forge <em>tika # as alternative</em> java --version #this one checks the installed java version in the command prompt |
Having this, the…
VBA – VLookup with Multiple Criteria in Excel without Excel Formula but with VBA
Ok, the title became too lengthy, but the idea is to try to duplicate the beauty of what this formula does:
|
1 2 3 4 |
=INDEX(myTable[#All],MATCH(1, (myTable[[#All],[Profit]]=C9)* (myTable[[#All],[Currency]]=D9)* (myTable[[#All],[Value]]=B9),0),1) |
And this is the cell of the formula above: Anyway, the strange thing was that we have beautiful…
Migrate Vue project from Vue 2 to Vue 3
Bash Commands
|
1 2 3 4 |
yarn add vue@next yarn add vuex@next yarn add vue-router@next yarn add -D @vue/compiler-sfc |
Changes in src/main.js Additionally, change main.js from this:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
import Vue from 'vue' import App from './App.vue' import router from './router' import store from './store' Vue.config.productionTip = false new Vue({ router, store, render: h => h(App) }).$mount('#app') |
To this:
|
1 2 3 4 5 6 7 8 9 |
import {createApp} from 'vue' import App from './App.vue' import router from './router' import store from './store' createApp(App) .use(router) .use(store) .mount('#app') |
Changes in src/router/index.js After changes the code should be looking like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
import { createRouter, createWebHistory } from 'vue-router' import Home from '../views/Home.vue' const routes = [ { path: '/', name: 'Home', component: Home }, { path: '/about', name: 'About', // route level code-splitting // this generates a separate chunk (about.[hash].js) for this route // which is lazy-loaded when the route is visited. component: () => import(/* webpackChunkName: "about" */ '../views/About.vue') } ] const router = createRouter({ routes, history: createWebHistory, }) export default router |
Changes in src/store/index.js This is how it should be looking:
|
1 2 3 4 5 6 7 8 |
import {createStore} from 'vuex' export default createStore({ state: {}, mutations: {}, actions: {}, modules: {} }) |

Python – DefaultDict Object. Or how to avoid the Key Error.
Have you seen the error below?

1 2 3 4 5 6 |

Of course you have. And you know, that it is because you have written something extremely unwise like this:
|
1 2 |
a = dict() a['foo'] += 5 |
Yeah. You cannot increment the value of a non-existent key. Unless… Unless you…
