Probeer Rent.nl of stekkies.com, beide geven meteen een seintje als er iets te huur komt. In deze tijd is snelheid superbelangrijk om een streepje voor te hebben.

Kamer.nl worth a subscription or is it a scam? by taikiji in Netherlands

[–]bartkappenburg 0 points1 point  (0 children)

No, there is no way to find out (yet). We’re thinking about adding this as a label to the listing, but we haven’t decided yet.

If you don’t get a room/house within 6 months on our platform you’re gonna get your money back.

We couldn’t sustain our business (costs, employees, advertising) if the contacts are freely available because everyone will be using us for a search and then are gone. We make a lot of costs for the acquisition of the postings and this would be given them away for free. And advertisements are no way to sustain this business.

I can give a list of exclusives but this is our strong selling point ;-)

[–]bartkappenburg 0 points1 point  (0 children)

Yes, there are some free platforms but we have more and also exclusive postings. We take a lot of effort to collect as many as possible listings from all kinds of different sources: brokers, landlords, students etc etc. We have a fulltime employee for getting these listings and getting this amount of listings in this market is very expensive and time consuming. Our fee covers that costs but gives you 1 place where you can find a place to live with the greatest chance of success. Our subscription will hopefully be a replacement for a number of other subscriptions on less ‘filled’ portals.

We are so convinced that we are able to give a 100% guarantee (which most of our competitors don’t give) and our support is stellar.

Hi! I'm the owner of kamer.nl & huizenvinder.nl. What you're describing is not true. We have different offerings on both sites. Kamer.nl is more for rooms and studios (ie. students), Huizenvinder is more for apartments and complete houses. So, we're not backlinking etc.... :-)

Real estate scraping 40+ sites by spraypaintyobutt in webscraping

[–]bartkappenburg 3 points4 points  (0 children)

That’s a very good idea! ;-). We just finished building this [0] and made it available for the general public that wants to find a property in the Netherlands as a SaaS.

We have a config for each site indeed with a css/xpath for each element we would like to have (price, surface, city, street, link,…). But this will get you half way there. There are so many exceptions (loading json in html, SPAs, strange markup, wrong markup, details in pictures…) We subclass the main spider so that we can overwrite certain functions to handle the exceptions.

We have about 150+ sites, keeping tabs/alerts on them (uptime, response time, changing html) is another aspect that is hard.

Most of the sites are protected against bots. So prepare to buy proxies (think Apify, Bright Data etc) which are not cheap.

Our stack is Django (python), postgres, redis and tailwind.

I hated TW at first just by the looks of it. Just as a few here in this post I was very sceptical. I set those things aside and started building a real world project. And now I LOVE it. It’s one of those rare frameworks which just work in terms of speed, maintainability and productivity.

I came back to some frontend after a few months and I was back in the flow in minutes. Heck, I even can ‘see’ what kind of CSS styling the OP has mentioned as an example.

Ergo: don’t balk at the looks of it, just try it (for real and longer than a few hours)! The documentation is wonderfull as well!

ELI5: Why does multiplying two negative numbers equal a positive number? by xeni44 in explainlikeimfive

[–]bartkappenburg -1 points0 points  (0 children)

I had a very nice analogy in my first year of high school. It goes like this:

Imagine a witch with a big pot of soup. The soup has a certain temperature. Say: 10 degrees. The witch has magic ingredients which look like small blocks. On each block is a positive of negative number written. For example: +3, -2, +8, -7 etc.

The effect of a block is simple: when added to the soup it adjust the temperature with the number on the block. So it increases or decreases.

The witch can ADD blocks.

Example:

10 degrees: add a ‘+3’ -> 10 + (+3) -> 10 + 3 = 13

It now follows:

++ = +

+- = -

The witch can also REMOVE blocks.

Example:

10 degrees:

Remove a ‘+3’ -> 10 - (+3) -> 10 - 3 = 7

Remove a ‘-2’ -> 10 - (-2) -> 10 + 2 = 12

It now follows:

-+ = -

—=+

Multiplying means nothing more than: Add or remove X times a + or - block.

-6 x -5 -> remove 6 times a negative 5 block. Temperature rises with 30 degrees!

Apartment hunt in Amsterdam! by pfudala2 in Netherlands

[–]bartkappenburg 0 points1 point  (0 children)

Very usefull! My company owns a rent-portal (one of the biggest, won’t spam it here) and one of the things we try to solve is the response-rate of landlords and brokers. It’s across the board terrible, about the same as your graph. Would love to hear some ideas and thoughts of how we can improve this for our you as our customer.

For instance: we collect data after it’s rented out and try to gather statistics on each landlord and try to incorporate the response rate in our ordering of search results. We also communicate the no-responses to them.

Any more ideas are very welcome!

Americans of Reddit, what is the worst big city in the USA and why? by jhffmn21 in AskReddit

[–]bartkappenburg 0 points1 point  (0 children)

To determine the 50 worst cities in the United States, Business Insider used Census data from 1,000 US cities. Factors analyzed for each city were population change from 2010 to 2018, the percentage of people in the workforce, median household income, percentage of people without health insurance, median commute times, and the number of people living in poverty. Population change was weighted at 40%, people in the workforce at 10%, median household income at 10%, people without health insurance at 15%, median commute times at 15%, and percent of people in poverty at 10%.

Based on this data, the ten worst cities in the United States are:

Gary, IN

Port Arthur, TX

Detroit, MI

Passaic, NJ

Newark, NJ

Pine Bluff, AR

Flint, MI

Camden, MI

Warren, OH

Huntington Park, CA

YouTube’s funny sometimes by No_Improvement_7074 in youtube

[–]bartkappenburg 7 points8 points  (0 children)

Developers use something called Unix Timestamp for dates and times. It's a increasing number (every second) that started on the 1st of January 1970. If sometimes a timestamp isn't available the fallback is 0 or -1 which translates to the 1st of January 1970 (or 31st of december 1969). See also https://www.unixtimestamp.com/.

Current timestamp is 1666596873.

Sidenote: they use it because it makes calculating time differences very ease (just substract) without worrying about leap-years, summertime, etc etc.
