Posture

Tue, 18 Nov 2025 11:23:25 +0100

Getting older and having the sedimented layer of bad posture and movement finally catch up to you is not nice.

This is a way to sort out available information.

Conlang Cipher

Fri, 07 Feb 2025 20:22:17 +0100

Using a language as encryption

Languages are governed by certain laws/principles, that reflect the relationships between elements. For example, element frequency: you generally have a few elements which are very common, and a long tail of rare events.

To make a language hard to learn, break those rules. Make each word/phoneme/letter equally frequent. Common words are short and have several meanings, long words are rare and generally have fewer meanings (as they are more specific). Turn that the other way round. Make long words frequent and unspecific.

Differential Geometry

Sun, 12 May 2024 15:37:03 -0400

Differential geometry is for many reason a very important branch of matematics and has many uses throughout physics.

I have tried to learn it well many times but every time I have met some kind of obstacle in the form of hard concepts or time available.

I am now again trying to learn the subject together with Lie and representation theory in order for me to better understand QFT and modern physics.

From what I have gathered the Schemes seem more academic and language oriented while CL has more libraries and is less clean.

AI and Programming

Tue, 30 Apr 2024 23:49:54 -0700

Already is programming a task that exists on the upper rungs of the great abstraction ladder; most software engineers and programmers are blissfully unaware of the details of compilers, interpreters, cache, CPU cycles and registers. I’d dare to say that even most of the details of the most used programming languages today remain elusive to most of its users.

Yet, we complain that writing code with natural language is somehow bad. Using an AI to generate code seems off to many, using it to play Go or generate art is somehow cheating.

“The age of Average”

Alex Murrell writes about what he calles the “age of average”: The age of average — Alex Murrell.

The tendencay for a lot of the stuff we surround ourselves with and produce to seem the same these days. I would like to add some cultural caveats to that statement as I am sure you could find something different if you wished; it is out there. But it is getting increasingly hard to find it.

Collapse

Tue, 02 Jan 2024 04:52:42 +0100

On the loss of knowledge and backwards developments that can and have happened in human future and history.

Preventing the Collapse of Civilization

A talk about the loss of earlier civilisation’s loss of knowledge and a thought about the same happening in game engine design and making.

Scott And Scurvy (Idle Words)

Third, how technological progress in one area can lead to surprising regressions. I mentioned how the advent of steam travel made it possible to accidentally replace an effective antiscorbutic with an ineffective one. An even starker example was the rash of cases of infantile scurvy that afflicted upper class families in the late 19th century. This outbreak was the direct result of another technological development, the pasteurization of cow’s milk. The procedure made milk vastly safer for infants to drink, but also destroyed vitamin C. For poorer children, who tended to be breast-fed and quickly weaned onto adult foods, this was not an issue, but the wealthy infants fed a special diet of cooked cereals and milk were at grave risk.

Tech Contracts

Tue, 02 Jan 2024 04:10:58 +0100

My brother looking for a job recently reminded me of some seemingly common contract practises I have come across earlier in my life. Notably the clauses that state somthing about what one does on ones spare time and/or after one leaves the job.

It seems that there typically are restrictive clauses in these regards. Something like:

We own everything you do
You cannot work a similar job after leaving this job
We expect you to dedicate yourself 100% to the company project/mission

etc.

Improvisation and ear training

Wed, 13 Dec 2023 11:39:04 +0100

Clark Terry

Jazz legend Clark Terrys’s tips for learning to improvise:

Imitate - listen, learn by ear, trascribe, absorb touch and time of a player
Assimilate - completely internalise concepts
Innovate - create fresh and personal approach

Interestingly the article quotes Dalí:

Those who do not want to imitate anything, produce nothing.~Salvador Dalì

However the only Catalan version of this quote I manage to find is:

Les persones que desitgen imitar-ho tot no acaben produint res de res.

Internet Navigation

Wed, 13 Dec 2023 11:00:00 +0100

As the internet has changes, so has the ways we navigate it. Nowadays most navigation is done with search engines and links though social media and instant messaging (I think).

Photic sneeze

Tue, 12 Dec 2023 17:44:27 +0100

All my life I have been sneezing when relatively suddenly exposed to bright light. As an example walking out into the sunlight after some time inside. Usually it happens in bursts of one-three sneezes that are nigh impossible to hold back.

As for many things that happen in our own world we don’t question them all too much. I always found it a bit strange that I happened to sneeze like this, but not overly strange nor strange enough to research.

Dependency Security

Fri, 08 Dec 2023 12:57:21 +0100

Dependency security has always been an important type of attack vectors for computer systems. The antidotes are two in number:

audit everything
Roll your own

I do not have numbers so this remains an opinion but with the fact that computing systems have massively increased in complexity in mind, it is reasonable to assume that the numbers and topology of dependency trees have grown in size and complexity over time for most software projects. I believe it would not be too difficutlt to find numbers supporting this observation.

Encryption

Fri, 10 Nov 2023 22:41:32 +0100

Encryption is making some payload unavailable to any but those who hold the secret to unlock it.

Full disk encryption (FDE)

This means encrypting the entire disk of some system, at least most of it. It is then unlocked by a user wanting to use the system.

This is great if you loose your stuff while it is in an encrypted state. But it it is not then it won’t help you.

GPG

Fri, 10 Nov 2023 21:23:31 +0100

PGP (Pretty Good Privacy) and GPG (GNU Privacy Guard) are suites of tools ment to aid in encryption, decryption, signing, verification etc. PGP is propetrietary (Semantec) and GPG is open source. In essence the two are identical.

Moving around the internet one occasionally stumbles upon people’s PGP/GPG signatures and keys. These they share so that one might communicate privately with them online.

This seems nice enough but the entire format/protocol/suite has had and continues to have great problems and weaknesses and cannot be said to work as intended.

iPod Classic Upgrade

Tue, 07 Nov 2023 18:06:45 +0100

I foud an old iPod Classic lying around. I knew I had it, but now I actually found it.

But the HDD was broken and slow and the battery rather done. I figured there must be something one could do to fix that.

It was loaded with music which I hope to be able to extract.

It also seems there are pleny of ways to upgrade and fix it: An iPod for 2022.

BSD

Sun, 05 Nov 2023 22:08:32 +0100

For various reasons I have lately found myself drawn more and more towards open source software and thinking more about privacy issues.

For quite some time I have also been thinking about moving to a Linux/UNIX OS and a different laptop and computer system all together. This has been for many reasons:

I love my Mac, but it’s software opaqueness makes me doubt
I had a creepy experience during an Apple Support session wherein an Apple support agent could suddently control my Mac remotely. All Macs come with this software installed by default.
Macs are expensive.
MacOs does not run on other hardware
The long term perspective is unclear: new Mac with M Pro Max Apple Silicon processor every year?

I do however love the hardware build quality and Apple as a company does many, many things right I think.

Internet Is Broken

Thu, 02 Nov 2023 09:45:11 +0100

Long ago, as many others, I started noticing the fact that Google search results for reviews and articles was basically filled to the brim with link farm content pages. Especially for Norwegian content in my case.

Email has been broken for years too with the amount of marketing and spam-y content coming in on the daily.

AI will make this worse arguably (AI future), but this author argues that the internet is alrady broken: The Internet Is Already Broken.

AI Future

Wed, 01 Nov 2023 15:47:54 +0100

AI crap arues that the future of AI is boring old capitalism:

It will be a tool that substitue otherwise uninteresting tasks and otherwise displace a lot of human positions that have people do a lot of these tasks. But on top of this we’ll have problems with automatic generation of content: books, spam, SEO, on social media and in politics and ads.

Open Source

Wed, 01 Nov 2023 12:31:31 +0100

SaaS

Using SaaS software seemingly inevitably leads us to give up our freedom on the internet. Why? Because you are using a program that you don’t have access to, and that in most cases doesn’t even run you your own device.

The cloud, in most cases as of now, makes this a fact for most people.

One could argue that GNU exists on the far side of the privacy/free software/open source “spectrum”, being quite adamant about these things.

Wordpress Profiling

Fri, 13 Oct 2023 15:55:10 +0200

Query monitor

Use the Query monitor plugin to check:

errors
load times
cache status

For logging you can also use its debugging and profiling features: Profiling and Logging in Query Monitor:

Logging

do_action( 'qm/debug', 'This happened!' );
// qm/emergency
// qm/alert
// qm/critical
// qm/error
// qm/warning
// qm/notice
// qm/info
// qm/debug

// Instead of actions one might also use static methods:

QM::error( 'Everything is broken' ); 
// Other log levels also available

Profiling

do_action( 'qm/start', 'foo' );

// Run code
slow_call();

// Time laps if necessary
do_action( 'qm/lap', 'foo' );

do_action( 'qm/stop', 'foo' );

Natalism (and antinatalism)

Fri, 13 Oct 2023 13:13:55 +0200

Antinatalism

A set of opinions and arguments that counter the notion that having children is something that we as humans should do. The mains lines of argument as far as I know are:

Climate change will make the world and thus life very bad for many in the future. Bringing somebody into this would be unethical.
Life is inherently filled with pain, more pain that pleasure overall, and forcing this on “somebody” would be unethical.
Human cognitive abilit makes us question our existence and the univers to the extent that existence itself becomes meaningless to us. Bringing somebody into a life of essentially meaningless existence is unethical.

Ha en lett tilbakelent rygg, Trekk skuldrene bak og ha dem senket. Øvre skjermhøyde bør være i pannehøyde

Albuene bør være 90 grader, inntil kroppen og overarmen parallelt med gulvet. Hvil 2/3 av underarmene på skrivebordet

Håndleddet bør være avslappet mens du bruker tastatur eller mus.

Tilbehør og arbeidsverktøy bør være så nær deg som mulig. Plasser tastaturet der hendene naturlig faller ned

Korsryggen bør støttes med en pute slik at du har en S-formet rygg.

Ha hoftene i 90 grader eller bredere stilling mens du sitter. Dersom mulig, ha hellende posisjon på setet.

Føttene må enten være på gulvet eller hvis nødvendig ha en støtte under

Husk å variere arbeidsstillingen ved å stå mer. Hev senk pult kan hjelpe.

Ha korte pauser i arbeidstiden. Hjelper mot produktivitet og sunnere mental helse.

Georgism

Sun, 12 Feb 2023 16:06:56 +0200

Georgism or more recently Geoism refers to an economic ideology that revolves around taxation of finite natural resources and products directly derived from the commons.

Generalism

Sat, 31 Dec 2022 19:24:11 +0100

Terms

Let’s start with a definition:

n. polymath: person with simultaneously wide and deep knowledge

The word polymath comes from Greek, πολυμαθή polymathēs, a participle meaning “having learned much”.

An equivalent Lithuanian participle (with qualifying adverb…) would be daug mokęsis.

the term used in Latin is homo universalis, “universal man”.

Other similar terms:

Generalist
Renaissance man
Jack of all trades colloq.

I find it hard to separate these terms in any meaningful way.

Morality of Being Rich

Mon, 24 Oct 2022 18:21:30 +0200

Purely moral concerns

Separating the concerns of earning and retention¹ is a nice way to argue for the morality of riches. The point is that whether you earn and deserve earning much money and whether you should retain it after the fact, are different and separate moral questions.

Thus, retaining wealth is imoral. Earning it is not.

There are obvious logical pitfalls that one can fall into by following these arguments too deeply. This sort of reductionism nullifies the applicability of the principles that could otherwise arise from a considerations like this.

Steady State Economy

Sun, 23 Oct 2022 13:06:20 +0200

A steaty state economy is an economy of stable or mildly fluctuating size¹.

Often discussed in relation to ecology and economic growth.

Economic growth must be separated from economic development. The former implies monotonic growth of consumption and production. The latter implies redistribution, changes in uses, improvement of methods of extraction, increasing efficiency and so forth.

A steady state economy implies constant populations of people and material/energetic throughput.

This throughput might change due to the aforementioned development and related increase in efficiency, but due to physics and the fundamental, non-negoitable laws of thermodynamics there is a maximunm size given a certain ecosystem society is to be in.

Checksums and Signatures

Fri, 21 Oct 2022 09:52:20 +0200

Checksums

A checksum is a computed fixed length string calculated from the contents of a file.

In principle modifications to the file will also yield a different checksum. There are however ways to avoid this and these properties depends greatly on the algorithm used to calculate the checksum.

Example of two hashing algorithms used for checksumming on mac Os:

# MD5 checksum 
md5 filename

# SHA256 checksum
shasum -a 256 filename

Cryptographic hash

These are fixed length strings calculated from files with additional properties in the case that the hashes are strong.

Woodworking Workshop

Sat, 07 May 2022 14:42:08 +0200

Setting up a space for work, be it programming, doing repairs, drawing, carving or doing carpentry, is hard and important.

Hard because setting one up properly means having the experience to know what your workflows demand as well as the foresight to see how the space itself can serve those needs in the best way possible.

Important because having a space that really affords your work, makes it easier, makes it feel good to do, really makes a difference when it comes to doing said work.

The results, looking apart from the specific conclusions; how much does talent account for and such, it largely confirms what seems to be the consensus: tailored education and freedom to explore as a child are great enablers. That is if one is free from the strife of negative relationships and other too tiresome emotional burdens.

Shaker

Practical and lacking decoration or ornamentaion. The furniture is made for its use.

Because of their religious beliefs, the Shakers thought the act of making something was in itself a sort of prayer. Thus making something well could be seen as an act of divine obligation.

Federal style

Use of: veneering, traditional joinery, heavy curves, elaborate details and patterns. Seems very US-governmental to me.

Knowledge Portfolio

Mon, 17 Jan 2022 20:03:37 +0100

I first encountered this concept of the knowledge portfolio in the book The Pragmatic Programmer.

The concept can be said to loosely be:

Looking at the collection of knowledge you posess as a portfolio akin to the ones we find in investment.

This can potentially have the power to serve as a partial heuristic for making good career and knowledge decisions.

Notions

From this perspective the things you know are assets that:

Web Components

Mon, 10 Jan 2022 08:46:49 +0100

A way of creating (“browser native”) separate components/elements with HTML, CSS and Javascript.

The Web components technology consists of three different sub-technologies:

Custom elements
Shadow DOM
HTML templates with <template> and <slot>

1. Custom elements

User-definable HTML elements.

Element names require the use of kebab-case.
Functionality is implemented by a ES 2015 class
Elements can be defined as extensions to in-build HTML elements

To define elements use CustomElementRegistry: customElements.define(name, constructor, options)

Web Assembly

Mon, 10 Jan 2022 08:40:06 +0100

Asssembly like language that runs in web browsers. The file extension is .wasm and these modules can be loaded and run through Javascript.

Allows fex. C/C++/Rust to be compiled for a browser target. The Wasm code then runs in a sort of virtual machine environment on the end-users machine.

Setting Up a Routine

Sat, 18 Dec 2021 16:01:53 +0100

Tips

Stick to actionable habits
Consistency is the most important thing
Evaluating whether a habit is worth implementing is as, if not more, important that the actual implementation
Routines can be place-specific

My optimal habits

Being in a perfect flow these are the things I’d like to habitually execute:

Reading: consume knowledge
Notes: internalise knowledge
Anki: retain knowledge
Meditation: find focus
Movement: get around outside
Exercise: targeted physical practice

Inspired by Julia Evans’ post: How to use dig

DNS is basically responsible for translating domain names to actuall IP addresses so that your computer can send your requests to the right server in the network.

Reverse DNS lookup

in-addr.arpa is the domain used for reverse IPv4 lookup
op6.arpa is for reverse IPv6 lookup

Here the IP in question is added as a subdomain in front of the ones in the list above. The DNS info is given in the response.

Advancing as a Programmer

Sun, 28 Nov 2021 18:55:53 +0100

About how I can become a better programmer. What directions might I take my skills? Where should I put my energy?

This note is framed in light of the following texts:

Beating the Averages (“Classic” P. Graham essay on power)
In defense of blub studies
A defense of boring languages.
Get better at programming by learning how things work
What technologies should I learn?

That is founding the exploration on the notion of a imagined dichotomy between learning “boring” details (blub studies) and learning new shiny things.

Sleep

Mon, 08 Nov 2021 22:36:43 +0100

Sleep and modernity

This article¹ in the Norwegian Harvest Magazine describes the central arguments of another English essay regarding sleep from 2003 by Roger Schmidt ².

Notably the dawn of the “modern lack of sleep” is set to 1650; the year of the introduction of caffeine in the form of tea and coffee to England and not (as is more typical) to the introduction of Edison’s lisght bulb.

The article also speaks of the introduction of modern time keeping devices and the disappearance of the old cyclical time in much the same way as the Danish historian Søren Mørch in his -in my opinion fantastic- book Store forandringer.

Exercise

Mon, 25 Oct 2021 15:52:31 +0200

Ballet/Barre

This, really, is the big takeaway for anyone who learned about fitness through watching Jersey Shore: You don’t need a bench press, a squat rack, and a pile of 45-pound plates to get a good workout. You just need some very focused movements, and a willingness to walk through a fiery hell of discomfort.

from 5 Reasons Why Men Can (and Should!) Do Barre Class - GQ

It should be noted however that this kinid of exercise does not build muscle in the same way as more traditional compound movement strength training.

Woodworking Tools

Thu, 09 Sep 2021 21:54:13 +0200

Wanting to start making chairs and some types of furniture I have bought some books.

Now, books alone might do for a mathematician but for woodworking you need tools as well.

I have chosen to learn to primarily work with traditional hand tools. This due to risk and cost factors as well as affinity for tradition.

General advice

Buy the best tools as you can afford
Quality is very important and really makes a difference
Tools must be maintained, and this must be learned
Skilled maintenance is as important as skilled use

Choices, choices, choices

Genius, Talent, Inheritance

Tue, 11 May 2021 23:03:30 +0200

Where does talent and genius come from? Are they given or not at the onset of our lives? How much of it is malleable?

A very interesting and indeed potentially touchy subject, because of its ties to things like eugenics and what I’ll call “fundamental issues regarding the worth of humans”.

EA-community, Slatestarcodex

The conclusion from the two articles below seem to be that it (genius, talent) is inherited:

genetically
sociologically

Degrees

As is common the Earth is divided into patches by our agreed upon coordinate system of longditude and latitude.

Both of these are measured in degrees. Latitude has a range of 0-90° (North and South). Longditude has a range of 0-180° (East and West).

There are 360° in one revolution (as is common), and each degree is further divided in (arc)minutes, each minute being 1/60 of a degree.

Chord Types

Wed, 14 Apr 2021 11:19:54 +0200

Depending on how you think about them chords can be many things. Some basic notions and assumptions that one might come up with at first hand:

They consist of multiple notes sounding together
They can consist of notes from different octaves
The notes should be somewhat consonant (sound well together)
They can be “vertical” as well as “horizontal” as they can be arpeggiated and thus stretched out in time.

Hence we might say that:

Figures of Speech

Sun, 07 Mar 2021 23:34:07 +0100

Continuously updated with my studies of figures of speech.

The Wikipedia list is very good, see links below.

The quote below from Wikipedia really explains what these are:

A figure of speech or rhetorical figure is a word or phrase that entails an intentional deviation from ordinary language use in order to produce a rhetorical effect.

Figures of speech in “classical western rhetoric” come in two types:

schemes: changes in the structure/pattern of usage
tropes: changes in the general meaning

Verbum volitans

Using a word that everyone (the audience) is thinking about before it is uttered/encountered.

Piquing Interest

Sun, 07 Mar 2021 16:39:54 +0100

Now, the relevant part for this note is the second point; which questions can we ask that will pique interest?

In other words how can we build a bridge between the “knowledge landscape” that the person we’re talking to is in and this new uncharted territory?

HDI/SDI Indices

Fri, 18 Dec 2020 16:05:31 +0100

SDI

Quantifies amount of development attained per ecological footprint; resources used to get there
To do this it:
- Caps gains from the income subindex at $20,000
- Incorporates an ecological footprint dependent on:
  - material footprint
  - carbon footprint

… The income index here differs from that used in HDI in that it incorporates a sufficiency threshold below the HDI’s maximum value of $75,000 (2011$ PPP). This is because to achieve an income of $75,000 per capita is empirically incompatible with planetary boundaries. Nations with income over $60,000 have an average material footprint of 40t per capita (nearly six times over the planetary boundary) and CO2 emissions of 22t per capita (nearly 13 times over the planetary boundary). These levels of ecological impact are highly destabilizing and cannot be universalized. In this sense, the HDI income index effectively precludes nations from achieving very high HDI while at the same time remaining ecologically sustainable. …

Extinction of Species

Sat, 12 Dec 2020 23:40:51 +0100

That some species go extinct is in fact quite natural and has been happening in natura for as long as it could have.

The rate at which species go extinct in this way is called the background extinction rate¹. Estimating this rate is very hard and estimated rates thus differ greatly.

It is however agreed upon that the current actual rate of extinction far superseeds that of the background extinction, being 100 or possibly thousands times larger. ²

Topology

Sat, 10 Oct 2020 18:32:25 +0200

Topology is the study of mathematical objects endowed with the “smallest” structure necessary in order for continuity to be well-defined on said object.

Thus topology is, simply put, the study of continuity.

Highly relevant are also the properties preserved under general continuous deformations of topological spaces. These are called topological properties.

Some “basic” but very important examples are:

Cardinality (dimension)
Connectedness
Compactness

This section from Wikipedia explains these very well:

Dough

1kg tipo 00 flour
6,5dl water

Mix for 3 minutes, cover with a damp cloth and leave for an hour to rest.

10g yeast
15g salt

After one hour, add yeast and salt and knead for 15 minutes (on slow speed if using a machine). Put in a lightly oiled bowl, cover and let leaven for at least 2 hours.

Lightly massage the air out of the dough. Divide in pieces of more or less 250g each and shape into balls. Cover and leave on a floured surface for at least 45 minutes.

Sustainable Food

Mon, 21 Sep 2020 18:29:08 +0200

My Principles

Prepare only what you eat
Eat only what you need
Buy foods that are responsably produced
Avoid carbon intensive foods most of the time

Also, this really goes hand in hand with general healthy eating

Chart: The Carbon Footprint of the Food Supply Chain

Specifics

High carbon foods (Buy and eat very rarely)

Beef (Beef from dairy herds is significantly better than beef from beef herds)
Lamb
Cheese
Chocolate
Coffee
Prawns

Lower carbon foods (Ok)

Olive oil
Fish
Eggs
Rice
Milk
Nuts
Potato (The most carbon intensive vegetable 2.9kg co2e/kg)
Vegetables in general
Fruit
Lentils
Beans

Notable facts

The type of food is much more important for the total emissions than transport, packaging etc.
We should strive to avoid high carbon foods, but cheese/chocolate are “better” high carbon options than beef simply because we tend to eat less of theese than beef once we eat them.

Coffee

Espresso: 0.28kg - 0.06kg (depending on growth and farming)
Latte: 0.55kg - 0. 33kg

Wendell Berry’s criteria for tool replacement

The new tool should be cheaper than the one it replaces.
It should be at least as small in scale as the one it replaces.
It should do work that is clearly and demonstrably better than the one it replaces.
It should use less energy than the one it replaces.
If possible, it should use some form of solar energy, such as that of the body.
It should be repairable by a person of ordinary intelligence, provided that he or she has the necessary tools.
It should be purchasable and repairable as near to home as possible.
It should come from a small, privately-owned shop or store that will take it back for maintenance and repair.
It should not replace or disrupt anything good that already exists, and this includes family and community relationships.

Quantum Mechanics

Fri, 11 Sep 2020 23:29:37 +0200

Quantum mechanics is the the foundation of all the quantum sciences, most notably QFT.

Dirac-von Neumann axioms

The space of states is a complex (countably infinite) Hilbert space $\mathbb{H}$. The following axioms apply to the qm system:

The observables are defined as self-adjoint operators on $\mathbb{H}$
The state $\psi$ is a unit vector of $\mathbb{H}$
The expectation value of an observable $A$ is $⟨\psi,A\psi⟩$

From these principles it is possible to derive the Schrödinger equation.

Productivity

Fri, 11 Sep 2020 18:59:31 +0200

Culture taught us this is important.

It also taught us that we should strive for it. #sad

For me it makes sense to be productive not to be able to always do more, but rather to do the things I have to do faster so that I can get on with my life.

Pomodoro technique

The practise of breaking productive work into chunks typically of 25m with short breaks of 3-5m in between. For every 4 chunks you do a longer break of 15-30m.

Zettelkasten

Fri, 11 Sep 2020 18:59:31 +0200

The Zettelkasten (technique) as originally conceived by the sociologist Luhmann (who co-authored an impressive body of work) is a method for taking and storing notes. It is:

Nonlinear
Fragmented and atomic
Deeply interlinked

It’s original form as used by Luhmann was old archive cabinets filled with index cards with various information on them. Each card had an id which was used to link it with other cards.

Using these links you can browse this interconnected web of information by following links around.

Julia

Sat, 02 Nov 2019 10:55:39 +0100

Julia er et relativt nytt høynivå programmeringsspråk med god syntaks for matematikk og modellering. Det lånes iherdig fra anndre språk som Lisp, Matlab, C, Matematica og Haskell. Det er et flerparadigme språk som støtter både prosedyrisk og funksjonelle kodestiler. Fra Lisp har også Julia fått metaprogrammeringsegenskapene sine, som er solide og kan brukes til å endre måten kompileren kompliserer og bygger kode før den blir gjort om til maskinkode.

Julia er et så kalt JIT-kompilert (Just In Time) språk som kompileres ned til native maskinkode rett før det kjøres på maskinen. Dette står i motsetning til:feks. Java som bygges ned til bytekode som så må kjøres inne en JVM (Java Virtual Machine); uten denne kan ikke Javakode kjøres. Python bruker også en annen tilnærming i det at det er et kommandotolket språk (interpreted) som betyr at koden blir parset og kjørt på samme tidspunkt; ingen kompileringsmellomstadie.

Ekvator er som kjent på 0°. Her er noen andre viktige breddegrader på jorden.

Vendekretsene

Nord: ~ 23°26'21" N
Sør: ~ 23°26'21" S

Altså ca. 23,5° nord og sør, for de som ikke viste det er denne vinkelen lik helningsvinkelen for jordas akse.

I mellom den sørlige og den nordlige vendekrets vil man oppleve at solen skinner rett ned på jorden en gang i løpet av året. Over disse bredegradene vil dette aldri skje.

JS Store pattern i Vue

Sat, 02 Feb 2019 15:31:00 +0100

Når man utvikler en JS app med et moderne rammeverk har man i de fleste tilfellene behovet for å lagre og hente ut informasjon på tvers av applikasjonens struktur. Eksempelvis har man ofte behov for å lagre den innloggede brukeren slik at denne kan hentes ut der den trengs.

Ofte vil det også være et behov for at denne dataen skal lagres i nettleseren og ikke forsvinne etter hver økt, til dette brukes ofte localStorage. Da oppstår det et naturlig behov for å synkronisere dataen sentralt lagret i applikasjonen og informasjoen lagret i nettleseren, dette er kode man gjerne vil isolere og kun skrive en gang. Et såkalt store pattern vil kunne hjelpe med dette.

regex og sed

Thu, 03 Jan 2019 19:55:00 +0200

Kraftfulle verktøy er ikke bare for nerder.

Mange ganger når jeg laster jeg tekst fra internett trenger teksten og endres på en eller annen slags måte. Feks. når jeg laster jeg vokabularlister trenger jeg ofte å renske ut alle de ekstra tegnene folk putter inn, i tillegg må de restruktureres slik at de ender opp i csv formatet.

For mange er ‘søk og erstatt’ funksjonen en god redning, men til flere typer oppgaver er rett og slett ikke denne god nok. Det er her regex eller Regular Expressions kommer inn, disse lar deg søke etter spesielle mønster og hente ut akkurat det du vil ha.
