Plot.ly is both a well known software library of impressive visualizations and a company providing software and know-how around visualizations.
With the libraries requiring a fair amount of know-how and programming to be useful to everyone there is now seemingly a multitude of tools that wraps the powers of the library and provides a great online-/web-browser experience to create impressive visualizations:
The access path to this quite powerful tool does somehow not be very easily found. So I am linking to it for your and my later reference.
The Android tablets I am using for my kitchen scale display and for myfitnesspal data-entry are aging quite bad and apart from the near-display death of one of the tablets both are not supported and updated anymore.
Using them therefore poses an increasing risk. After one of them almost died on me I was determined to replace them both. Looking at alternatives at the lowest possible price quickly showed that I am not going to get another Android tablet.
Instead I was ready to give a chinese company a chance:
I ordered it on 24th of June and it was delivered today. All in all I’ve paid 136 Euro for the tablet and 45 Euro for the keyboard attachement.
Despite the ridiculously low price this thing is quite impressive. It’s sporting a fast-enough Intel Atom processor with 1.4 ghz and 4 Gbyte of RAM. The 64 Gb of solid-state storage where quickly upgraded by an additional 400 Gb MicroSD card for local data storage.
As of writing this it’s still installing and updating the Windows 10 to 1903 but so far I am beyond impressed.
I’ll write more about the device when I’ve had more time to use it. One word for the keyboard attachement: the keyboard is good-enough. Not great but better than for example that on the Pinebook. The touchpad is very small but works – the thing has a Touchscreen anyway.
The first device in my household recently has updated itself to the newest Windows 10 1903 build.
On the very first moment of the login screen appearing and logging in I could tell that I hate one specific change that has made it into this latest update.
And it’s the default mouse cursor.
Back in the Pre-Windows Vista days, when I used to work for Microsoft, I was using the latest internal build of Windows and just around the first RTM (release-to-manufacture) build they touched up on the final designs.
I remember vividly when the mouse cursor had changed from the one we new and used since Windows 3 to a shorter tailed more “high-def” looking one.
Since then there were a couple of changes on the cursor but the general design was kept.
Now apparently with the latest Windows 10 update from 1803 to 1903 I got a new – old default mouse cursor.
By reflex I changed it back to the one I love and stored safely in a backup. I cannot stand the long tail and the weird pixel-ness of the cursor. It just looks kinda weird to my eyes.

How to build security into your software? It’s always simple to find examples where things gone wrong. Where security was compromised and things did not work out as the software authors envisioned.
As always there are new concepts and operating systems being implemented.
A particularly interesting example of security software design can be observed here:
In contrast to prior Google-developed operating systems such as Chrome OS and Android, which are based on the Linux kernel, Fuchsia is based on a new microkernel called Zircon. The name Zircon refers to the mineral of the same name.Google Fuchsia
So you now know what Fuchsia is. Now on to the actual example. For this we have to take a look into the developer documentation of Zircon:
So this describes a method to get random numbers from the systems cryptocraphically-secure-random-number-generator (CPRNG). It takes a pointer to a memory location as a parameter.
Now. What’s secure about that? It’s the behaviour of the method when it is encountering an unsecure situation:
It’ll kill the calling process when the pointer is not valid.
Hmm… I’ve set-up a script to automatically download a TV show about a year ago and just remembered it…
Apparently 1 year of this show is 167 Gbyte…
For completeness the download script – ignore my bad scripting:
#!/bin/bash # parameter 1: month # parameter 2: from day # parameter 3: to day # parameter 4: year # data -dmonday +%d next_monday=$(date -dmonday +%d) next_monday_month=$(date -dmonday +%m) next_monday_year=$(date -dmonday +%y) previous_monday=$(date -d'monday-7 days' +%d) previous_monday_month=$(date -d'monday-7 days' +%m) previous_monday_year=$(date -d'monday-7 days' +%y) next_friday=$(date -dfriday +%d) next_friday_month=$(date -dfriday +%m) next_friday_year=$(date -dfriday +%y) previous_friday=$(date -d'friday-7 days' +%d) previous_friday_month=$(date -d'friday-7 days' +%m) previous_friday_year=$(date -d'friday-7 days' +%y) for i in `seq 1 7`; do day=$(date -d'today+'$i' days' +%d) month=$(date -d'today+'$i' days' +%m) year=$(date -d'today+'$i' days' +%y) wget -c "https://rodlzdf-a.akamaihd.net/none/zdf/"$year"/"$month"/"$year$month$day"_sendung_dku/1/"$year$month$day"_sendung_dku_3328k_p36v14.mp4" done
Picture yourself in this situation. You connect to a network and nothing works. Except for this:
It is quite common to have DNS working in networks while everything else is not. Sometimes the network requires a log-in to give you access to a small portion of the internet.
Now, with the help of a tool called iodine, you can get access to the full internet with only DNS working in your current network:
iodine lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed.
It runs on Linux, Mac OS X, FreeBSD, NetBSD, OpenBSD and Windows and needs a TUN/TAP device. The bandwidth is asymmetrical with limited upstream and up to 1 Mbit/s downstream.iodine
Setting it up is a bit of work but given that you are anyway having access to a well connected server on the free portion of the internet it can be easily done.
Of course the source is on github.
Try to wrap your head around this: There are people out there that take the term “Maker” to new levels. People Like Sam Zeloof. He went out and created his very own integrated circuit designs and then he built them. Like the actual silicon, the die, the bonded chip, the IC. The real thing.
I am very excited to announce the details of my first integrated circuit and share the journey that this project has taken me on over the past year. I hope that my success will inspire others and help start a revolution in home chip fabrication. When I set out on this project I had no idea of what I had gotten myself into, but in the end I learned more than I ever thought I would about physics, chemistry, optics, electronics, and so many other fields. Furthermore, my efforts have only been matched with the most positive feedback and support from the world; I owe a sincere thanks to everyone who has helped me, given me advice, and inspired me on this project. Especially my amazing parents, who not only support and encourage me in any way they can but also give me a space to work in and put up with the electricity costs… Thank you!Sam Zeloof
Imagine you’ve got this ancient piece of technology in front of you. You clearly understand how the hardware works and you are even able to emulate the hardware on your modern-world computer.
Unfortunately hardware is only one half of the story. Software is the other half. And software at this time of the past was burned into chips which do not easily give their secret software away.
But let’s start with the hardware:
The IBM 5100 Portable Computer is a portable computer (one of the first) introduced in September 1975, six years before the IBM Personal Computer. It was the evolution of a prototype called the SCAMP (Special Computer APL Machine Portable) that was developed at the IBM Palo Alto Scientific Center in 1973. In January 1978, IBM announced the IBM 5110, its larger cousin, and in February 1980 IBM announced the IBM 5120. The 5100 was withdrawn in March 1982.
When the IBM PC was introduced in 1981, it was originally designated as the IBM 5150, putting it in the “5100” series, though its architecture was not directly descended from the IBM 5100.
And now on to the software:
The IBM 5100 portable computer came with some of its built-in programs stored in a read-only memory called the “non-executable ROS”. (ROS = “read-only storage”.) In contrast with the “executable ROS”, which supplies instructions to the 5100’s processor directly, the non-executable ROS is accessed using sequential I/O operations, a bit like a tape.
Most notably, the non-executable ROS holds the interactive interpreters for the APL and BASIC programming languages. These are not “native” 5100 programs but were expressed instead in System/370 mainframe and System/3 minicomputer machine code respectively. The 5100 runs emulator programs for those computers in order to host the interpreters, so perhaps it’s just as well that the non-executable ROS is non-executable.DATA
So this write-up is all about how the bits where pushed to the screen and recorded as pictures of the said screen. The characters in these pictures then where analyzed and with the help of machine learning the data could be successfully extracted. It is mind-boggling. And it is all on Github.
This project is a way for people to use CSS Grid features quickly to create dynamic layouts.
You can set the numbers, and units of your columns and rows, and I’ll generate a CSS grid for you! Drag within the boxes to create divs placed within the grid.
I noticed a lot of people weren’t using Grid because they felt it was too complicated and they couldn’t understand it. Grid is capable of so much, and this small generator only touches on a fraction of the features. The purpose of this is so people get up and running quickly, and create more interesting layouts.
Once you work with this a bit, I suggest checking out resources by Rachel Andrew, Jen Simmons, and Dave Geddes to dive deeper. There is also a CSS Grid Guide on CSS-Tricks, and a fun little game called Grid Garden to help you learn more!Source
When working on source files with wide-ranging scopes, I wish source editors could pin the declaration lines to the top of the window like section headers, something like this…Joe Groff on Twitter
This looks like something that would really make a difference when editing code. Let’s see how long until we get something like that in modern editors…
I/O is getting faster in servers that have fast programmable NICs and non-volatile main memory operating close to the speed of DRAM, but single-threaded CPU speeds have stagnated. Applications cannot take advantage of modern hardware capabilities when using interfaces built around abstractions that assume I/O to be slow. We therefore propose a structure for an OS called parakernel, which eliminates most OS abstractions and provides interfaces for applications to leverage the full potential of the underlying hardware. The parakernel facilitates application-level parallelism by securely partitioning the resources and multiplexing only those resources that are not partitioned.https://dl.acm.org/citation.cfm?doid=3317550.3321426

drop in replacement for tail -F that asks you if you are still watching
Just like Laura I am also was having a moment when I stumbled across tailflix.
For those not understanding the reference: At the end of an episode you’ve watched on Netflix you will be shown another one, and so on, and so on. Until if you have not touched the remote at all for several episodes Netflix will ask you “Are you still watching?”.

I am a happy user of the Apple Watch and iPhones in general. It’s working out great for me so far.
There are a couple of features that I would wish where there. And simple things like an hour-chime or hour/half-hour tap are frequently included into the WatchOS updates.
But some of the more specific features just won’t materialize on Apple Watch.
Think of this: You are doing your thing, you know, being a productive member of the society. And apart from the information “What’s next” the information of “When’s next and how long until then” is equally important.
I already had all information – like upcoming events – in my calendar. Why not have the watch display directly on the watch face how long I’ve got until then?!
You’re downloading it on your iPhone and when opened up first it will show you a list of your calendars.
You can turn on/off any of them in this app and by doing so you are selecting which of the calendars will be included in the calculation “how long until the next meeting”.
I’ve only selected one calendar which holds those appointments that I need to know how long until then. So it’s not the next work meeting. It’s important things.
On the watch, however many calendars you’ve selected, it will show you something like this:
So in this case it’ll show the hours until I have to wake-up. Whatever I put into this calendar will show up there. If I want with the name of the event, but most commonly I am using the bottom right version: just the hours/minutes until.
Unfortunately Rachel is quite busy and so there’s no update for the app to also support the new Modular Infograph complications of WatchOS 5 and up.
If you don’t know how those look like, here is a picture I’ve put together from Apples developer documentation:
So I am thinking to rewrite the app and include the new complications. In fact: I’ve implemented my “Discordian Calendar Apple Watch Complication” app as a test and exercise to learn how I would be able to rewrite “Time Till”.
Now the only thing I need is to be kissed by the muse that fuels the urge to just get it done :-).

Every month there are free games to download and try out with the Playstation Plus subscription. There was a game named “Conan Exiles” included and so my Playstation started the download.
After the download taking unexpectedly long I checked the download queue and found the reason why it would take so long to download. This game is over 82 Gbyte in size. This is quite unexpected.
Conan Exiles is an open-world survival game set in the brutal lands of Conan the Barbarian. Survive in a savage world, build your kingdom, and dominate your enemies in brutal combat and epic warfare.
Start with nothing but your bare hands and forge the legacy of your clan, building anything a small home to gigantic fortresses and entire cities. Wage war using swords, bows, siege weapons, and even take control of giant avatars of the gods and lay waste to enemy cities.
Explore a vast, seamless world full of challenge and opportunity. Hunt animals for resources, slay monsters for treasure, and delve deep underground to discover the secrets of ancient civilizations.Conan Exiles: The Game
It’s still downloading. But what content could await if it only fits into 82 Gbyte of (assuming) compressed data?!

There are new micro-projectors coming and they are looking good. After the first availability of really small and low-power but enough-light LED projectors (see here) manufacturers have apparently added a laser to the equation.
It is said that…
Unlike traditional projectors that constantly need to be focussed, the Nebra AnyBeam picture is always perfect. You can project onto curved or irregular surfaces with ease – perfect if you want to use it on the fly, or if you want to try your hand at a bit of projection mapping!
This thing will be available, according to the Kickstarter, as a all-in-one package with power and HDMI inputs. It’s got 720p inputs. Well. Well really?
And it will be available to the maker market as a RaspberryPi Hat…

As the replacement drive for yesterdays hard drive crash was put into place the storage array started to re-silver the newly added empty drive. This process takes a while – about 8 hours for this particular type of array.
Interestingly just 2 minutes into the process another drive dropped a bombshell:
Apparently disk 8 holds together it’s business so far but dropped a couple of parity errors into the equation.
This is bad news. But so far science still is on my side of things and no data has been lost.
But now redundancy is down completely. There’s no redundancy for now – until the replaced hard disk is fully integrated. My policy for these sized drives demands a minimum of 2-disk redundancy and for today this policy saved the day (data).
Actually let’s dive a bit into what it’s doing there to achieve 2-disk redundancy:
Synology Hybrid RAID (SHR) is an automated RAID management system from Synology, designed to make storage volume deployment quick and easy. If you don’t know much about RAID, SHR is recommended to set up the storage volume on your Synology NAS.
You will learn different types of SHR and their advantages/disadvantages over classic single disk/RAID setups. In the end, you will be able to choose a type of RAID or SHR for the best interest of your storage volume. This article assumes that as the admin of your Synology NAS, you are also an experienced network administrator with a firm grasp of RAID management.Synology Hybrid Raid
So you trade data redundancy and safety for useable disk space. Here this is compared to traditional RAID 5:
The Podlove project once again leads the way to improve the experience and the way we interact with knowledge and thoughts. With the most current announcement and introduction of transcription-support for podcasts. Click on it right now and try it yourself.
Fulltext-search. Listening to podcasts by reading them. This-is-amazing!
Transcripts are comingfrom the Podlove Publisher 2.8 announcement
Transcripts are an incredibly desirable thing to have for podcasts: they allow searching for specific parts, increase searchability by search sites when presented properly and they increase the accessibility of audio content significantly too.
However, transcripts have been considerably difficult to be created and used. Manually created transcripts are costly in terms of time and money and even if you spend the money there has been a lack of technical standards for storing and integrating transcripts into websites in a defined way.
This is now slowly changing: more and more automated speech-to-text systems are becoming available at reasonable costs and they are creating ever better transcripts with more and more languages being supported.
Still, automatic transcripts trail manually created transcripts in terms of accuracy, punctuation and so on but they are increasingly useful when they are primarily used for improving search results or helping you with your internal research when trying to find content in your older episodes.
New services are also coming up to deal with these problems by allowing users to quickly build on automatic transcripts and improve them manually in an assisted fashion. We will soon see a landscape of tools and services that will make creating transcripts easy and cheap enough for more and more podcasters so it’s time to come up with a good integration.
Last but not least, the WebVTT file format has become a de-facto common denominator for passing transcripts along, supporting time codes, speaker identification and a rudimentary set of meta data. While not perfect it’s enough to get a transcript infrastructure up and running and Podlove is leading the way.
The CPU/hardware related bugs surfacing the last couple of years have mostly been fixed by adjusting the software that is run. Sometimes only by disabling certain features of a CPU or patching the microcode in the CPU itself.
The issue with this is that by fixing these issues features got disabled and workarounds had been introduced that lowered performance. Dramatically so for some use-cases.
By how much? Well it really depends on your CPU and use-cases. But maybe you want to try yourself. If you want to know the most current parameters to pass to your kernel on boot-up to disable all the performance impacting fixes, go here:
It is not recommended to have this in productive use – as you can imagine. Those bugs where fixed for a reason.
