The Phantom of Heilbronn (or how for 16 years the German police hunted a serial killer who didn't exist)

(Thread, non sweary version here: https://t.co/iDOIhaFgIT)

Between the years of 1993 and 2009, police in Heilbronn, Germany were tracking just about the most elusive serial killer since Ted Cruz.

Known as the Phantom of Heilbronn, or occasionally The Woman Without A Face, she was implicated in so many crimes that the police eventually put out a reward of €300,000 for any information leading to her arrest.

The case that brought her to the media's attention and earned her two ridiculously badass nicknames

(honestly, if you don't want people to do murders you're going to have to come up with less glamorous nicknames - what's wrong with Jack Shitshispants or the Zodiac Cuck)

Positioning in CSS allows you to display your element wherever you want on the screen

But when I was learning it, I found it little bit confusing😅

So in this thread I'll try to explain it in easiest manner with practical implementation. Let's start

THREAD🧵👇

There are 5 values that you can pass in position property

- static
- relative
- absolute
- fixed
- sticky

In this thread we will be focusing on relative and absolute positioning as both are widely used

Let's start with understanding what document flow is?

📌 Elements are displayed on the screen as they written in the HTML document

Consider the following piece of code:

H1, P, H3 and div are displayed on the screen in exact order as they written in the HTML file.

As now you know about document flow, let's start with Relative positioning

📌 Relative Position

- Relative positioning do not take an element out of document flow
- Relative positioning is relative to element's original position which can be changed using offset

🔹 Relative position is relative to itself.

For example: Consider the code and output in the attached image below

As you can see red box is shifted 100px from left because I applied left offset after giving it relative positioning

[1/4] Ok this is really funny, check this out.
I was in the process of booking a flight via @OneTravel. Trying to make me book ASAP, they claimed: "38 people are looking at this flight".
Whoa, 38 is a lot, I have to hurry up. But first I have to check how they came up with 38 >>

[2/4] Right click and a quick "inspect" on the number, I found out the element's class name is "view_notification_random".
Awesome variable naming guys.
So you're _randomly_ trying to freak me out. Alright >>

[3/4] So what's your sophisticated pseudo-random algorithm?
Apparently, OneTravel are choosing a number between 28 and 45.
Because as you all know, based on serious psychological research, these numbers tend to make people book their flights fast #sarcasm #not42 >>

[4/4] Here's a bonus graph.
Thanks @IddoYadlin and #WolframAlpha.

1/12 @HathorNetwork offers a unique set of features for both builders and users. Some well known ones, others not so much. Let’s look at why you might want to consider Hathor as the layer 1 solution for your project. $HTR @HTRFDT #BuildOnHathor

2/12 Easy tokenization is the obvious one. You create your own token in less than a minute, no coding required.

3/12 As opposed to ERC tokens, your custom Hathor token is a layer 1 token. It inherits the same features and security as the native token, $HTR, effectively giving your token the same level of security as the #Bitcoin $BTC blockchain.

4/12 Hathor Network also passed their security audit by @SlowMist_Team so you can feel safe knowing that your L1 token fulfills the same security requirements as $HTR.

5/12 By configuring built-in nano contracts you will be able to add logic to your token. No coding required. Native nano contracts also mitigate the risk of bugs and security issues that comes with custom smart contracts development on other platforms. $HTR

maybe it's just leftover urges from being a toddler putting round pegs in square holes but every time I see a video card like this on ebay I want to buy it and also some RAM chips to fill it with

when I win the lottery I'm gonna buy all of these and a bunch of RAM chips, put them together, and then relist them right back onto ebay

I have a dream that one day all the super VGA cards on ebay will have full ram expansion sockets

that's a nice VLB video card you have there
be a real shame if someone were to UPGRADE ITS RAM

huh, I don't think I've ever seen RAM in that package
QFP DRAMs?

Because microtest TDD is more a "way of geeking" than a technique or a received body of knowledge, building one's faculties is a long and sometimes perilous effort. Let's talk about learning.

(I, too, feel a little relief just now, tho not as much as some, because recent events aren't an ending, they're the beginning of a lot of work.

Black Lives Matter.

Stay safe, stay strong, stay angry, stay kind.

Let's keep changing this.)

I want to approach the question(s) of learning TDD in some ways that are a little different from others I've seen. I've written two TDD curricula myself, and am involved currently in helping with two more. I see all of them, including the current ones, as "interesting failures".

At first, learning/teaching TDD seems like a road, then over time it seems to become a tree, and ultimately it feels much more like a spreading activation network, including lots of external triggers, plateau periods, and transformative experiences.

(I'm open to the possibility that this is what *any* judgment-centric skill looks like, but for now I just want to talk about TDD.)

"The engineers on my team just want to code. They don't want to have anything to do with product. They just want specs. What do I do?"

1/n Are you asking them do to X *and* do their "day job" as defined by their managers (and frankly your roadmap) ?

If so, start there...

2/n Do they have a reason to believe that doing X will in any way improve the quality of the product and make their lives easier? Have they ever seen X "work" ?

Show don't tell.

3/n Is there average day/week a quagmire of unnecessary meetings, wading through tech debt, struggling to get *anything* to work ... and jumping through process hoops to prove their worth?

If so...no they will not have bandwidth.

4/n How do incentives work on the engineering team? Maybe they want to help, but their "grade" is determined by something altogether different.

"I'd love to, but I am on the hook to deliver [some project] this quarter to make a good impression..."

Talk to eng management.

5/n Have they had any time to practice?

Or did they get thrown into the deep end the first time they were given a shot ... expected to brainstorm on demand, be as vocal as practiced PdMs and designers, and "participate" !

Make it safe to practice. Reasonable expectations.

People sometimes ask me what my vision of DeFi is. This is a very tough question. DeFi is very messy with thousands of experiments happening. But high level, I think DeFi will go through 2 phases:

During the 1st phase (next 2-5 years), we'll continue to build games, casinos, and speculative products.

This sounds uninspiring. But it has two main important consequences.

1) This will ultimately lead to hundreds of millions of users to install wallets and get uncomfortable with the UX.

2) This will force the tech (especially scaling) to mature.

Once we've achieved these two goals, phase 2 begins. In phase 2, products that serve real economic activities / integrated with the real economy will be built and flourish.

Right now, such products barely exist. @terra_money comes to mind. But this is the kind of products that I really look forward to. They are more economically sustainable, and create more value.

I like how mediawiki exports pages because there's nothing I enjoy more than parsing a 1 gigabyte XML file

and I'm doing simple-english-wiki! it's way smaller than english wikipedia
I can only imagine how impossibly unparsable that nightmare is

fun fact: when programmers need to write code to extract data from an XML file, the process usually goes like this:
1. find XML file
2. open it in a text editor, see what the structure is
3. write some code that parses that

do you really want to open a 1 gigabyte XML file in your text editor?

do you want to fucking die?

I used to run into this problem back when I worked for the government, because sometimes I'd click a database query log (don't ask why our logs were in XML, it's... complicated) and it would turn out to be 100mb

Tonight we are launching our Net Zero Carbon Roadmap for Leeds, which shows a pathway for how Leeds can get to net-zero emissions by the city’s target date of 2030.

Follow the live tweets @LeedsClimateCom #LeedsClimate #PCANcities

We're looking forward to hearing responses to the roadmap's presentation by members of the Leeds Citizens' Jury, Polly Cook of Leeds City Council, @SimonBowens of Friends of the Earth and Elizabeth Edgington of @BITC

Leeds’ carbon footprint has gone down: between 2000-2019 emissions fell by 40% (largely due to national decarbonisation of the grid).

Our share of the global carbon budget in 2020 is 31m tonnes; at ca. 4m tonnes a year, that’s used up by 2029

#LeedsClimate #PCANcities

During lockdown #1, emissions were ca. 43% lower – overall, in 2020, they were ca 13% lower than normal. Sounds encouraging, but this only delays the point we eat up our carbon budget by 2 months!
#LeedsClimate #PCANcities
4/

Following science-based targets, Leeds needs to make 70% reductions by 2025 – which means another 25% reduction in emissions in the next 4-5 years.

We need to accelerate significantly!

Time for a pulp countdown now, and today it's my top 10 digital watches of distinction!

After all, why wear a Rolex nowadays?

At #10: the 1973 Seiko 06LC. This was Seiko's first LCD wristwatch: a field-effect liquid crystal display showed six digits of time continuously - you didn't need to press a button to see it either!

At #9: the 1976 Bulova Computron. The side mounted LED display meant you could sneak a peek at how long your meeting was taking without anyone else noticing. Very chic.

At #8: the 1989 Nelsonic Nintendo. This is The Legend Of Zelda version and it's perfect for letting others know you are a master of corporate strategy!

At #7: the 1975 Uranus Calculator watch. This natty number has its keypad on the bezel, which does increase its size. "How big is Uranus?" is a frequent question you'll get if you wear this.

Next up in Privacy Technology at #enigma2021, Kelly Huang from @ethyca speaking about "GONE, BUT NOT "FORGOTTEN"—TECHNICAL & PRACTICAL CHALLENGES IN OPERATIONALIZING MODERN PRIVACY

Just imagine there's a global pandemic forcing everyone to stay home and buy their stuff over the internet. And you've been working on your sanitization-on-demand startup. You've got more users than you can count! ... literally, because your data's all over.

Now you're a multi-national international country with privacy issues because your information is all over the place.

Now a user writes to request you delete their data. Where is it? How do you do that? Who's responsible for privacy in your business.

How do you operationalize privacy rights?

Primary stakeholders:
* Legal
* Business
* Engineering

We spend a lot of time on Twitter analyzing the legal rulings, but it's harder where the "rubber meets the code" 🥁

(1) Since some people laugh at Cardano project and it's peer review aspect, let me share a story from work for all of you
(2) There is company called Databricks and they open sourced recently a technology called: https://t.co/gpZyKKiMVD . This technology is super important

(3) In BigData delta allows one to perform DELETE and MERGE operations contrary to Hadoop + Hive where this is not possible, seeking through many partitions finding customer data to remove and then rewriting it is not only expensive as an operation but also very dangerous

(4) This promising technology is something that many companies, which have big data turn into as they need to be GDPR compliant.
(5) I was always reading and accepting all details from their website as given and the "truth"

(6) There is however an amazing Principal Developer at our company that found some of the claims from their website as dubious, e.g. ACID claims on such a distributed file system
(7) It turns out this is not the first time this company advertises something that is simply not true

(8) on another occasion this company made untrue claims about Cassandra database and this then became source of disputes e.g by dr. @martinkl - my fave expert in distributed systems
(9) All professional developers also know of course famous Jepsen tests ->

help

stuff. just stuff. its all too easy to order more stuff. so much stuff. I dont need any more stuff but I cant stop ordering stuff.

why are chips often so expensive? how do chip companies determine the prices of their chips? a thread... 🧵

first thing chip companies do is to figure out the COGS - cost of goods sold. this is how much it costs them to produce a chip--not counting profit or anything else.

but before we can calculate that, we need to know The Life of a Chip, start to finish!

it starts as a raw slice of silicon, something like this. (0th step is a raw boule or silicon ingot, grown as a single crystal, that is sawn up like this)

then it gets run through a variety of processing steps. etching, diffusion, implantation, deposition, and others.

Been reading up a lot about these jabs, esp as I know they are going to be a condition of a return to normality

Was on a zoom call last evening with a testing company that had some fascinating evidence on protection etc.

I have more reading to do.

I do not want to be coerced into something I don't want, BUT i want normal back as soon as possible.

Basically i'm at the point in my isolation and thinking that I'll take whatever just so this bullshit can end.

That is a desperate mindset, but so is 12 months of being cut off from the world.

All i have is what goes round and round in my head.

There's no one else to help balance it.

So i'm in group 6, and my surgery are doing group 6 right now. And i am at the point i want to do it to get it DONE.

And also to study what happens. Because i have that kind of mind.

I remember Pandemrix.

But we live with risk every day.

I risk my life climbing walls with only a harness around my waist to catch me as i lean back and fall off

And rational risk assessment is at the heart of everything going wrong these last 12 months
