Telekom - Internet & Telefonie Anschluss aka SpeedLink 5501 Zyxel "plötzlich" defekt - service schlecht & inkompetenz

• Pro:
  • schneller Techniker vor Ort wenn man Business Kunde ist
• Con:
  • katastrophaler kompetenz & service
    • egal ob am Telefon oder vor Ort
      • beim ersten Anruf bei der Nicht-Business Hotline, tatsächlich schnell jemand erreicht mit dem Hinweis: Er sei der falsche, da nur für Privat-Kunden, hat dann doch wenigstens bestätigen können, dass der Anschluss noch nicht gekündigt wurde (wird bald erfolgen X-D)
      • die Business-Hotline wollte mich direkt einen Web-Chat (Bot) delegieren - beim zweiten Anruf mit Eingabe der Rufnummer hies es nur noch: sagt der AB-Bot: Sprechen Sie mit ihrem Berater (aber wer ist unser berater? X-D)
  • c.a. 2015 wurde uns von der Telekom ein SpeedLink 5501 aka ZYXEL irgendwas verbaut
    • dieses Gerät macht KEINE Automatischen Firmware Updates wie eine Fritzbox und weisst deswegen vermutlich über die Jahre GRAVIERENDE Sicherheitsprobleme auf
  • seit 2 Tagen möchte sich der ZYXEL nicht mehr mit dem VDSL 100000 der Telekom verbinden, einfach so?
    • (kann gut sein, dass ALLE SpeedLink 5501 Zyxel von aussen das Gerät “defektiert” / gehackt wurde, )
  • Technische INKOMPETENZ:
    • entgegen der Aussage sowohl der Hotline als auch des Vor-Ort-Techniker funktioniert die Fritzbox 6890 LTE SEHR WOHL am Telekom VDSL Anschluss
      • auf Werkseinstellungen, Fritzbox funktioniert am VDSL Anschluss der Telekom (#wtf!?)
    • entgegen der Aussage beider Telekom-Techniker zieht sich die Fritzbox LEIDER nicht die VDSL-Zugangsdaten automatisch
      • hab dann doch noch irgendwo die Zugangsdaten gefunden…
      • Internet geht jetzt wieder
      • Telefonie funktioniert leider immer noch nicht… wen soll ich anrufen? X-D
    • Telekom arbeitet mit immer mal wieder wechselnden Hardware Herstellern zusammen, aber nicht mit AVM (FritzBox)
      • egal wie schlecht die Qualität dieser Hardware ist
  • dem Aktien Kurs getriebenen Konzern Telekom sind die Kunden, die seit JAHRZEHNTEN schlecht anbunden sind, einfach egal
    • ganz ehrlich: Ist das Kunst oder kann das weg?
      • sind jetzt privat bei Starlink und bisher sehr zufrieden - die Telekom konnte uns nicht mal die volle Bandbreite von VDSL 1000 liefern (seit JAHRZEHNTEN)

GNU Linux Debian 11 - How to setup Brother QL 600 LabelPrinter

it’s a two part process:

1. install the drivers

(thanks all involved great work 🙂

<span style="color: #00ffff;">su - root
apt update
apt install printer-driver-ptouch
</span>

2. install the printer via cups web browser interface

http://localhost:631/

or:

https://localhost:631/

-> Administration -> Add Printer

select the driver for QL-650TD

click on “Add Printer”

stick with the default options.

3. (optional but recommended) get some templates for LibreOffice:

https://download.brother.com/welcome/dlfp100385/officetemplate.tar.gz

4. HAPPY LABELING 🙂

(print some nice sentences… and make ’em stick… e.g. to a traffic light post… )

for example:

it can do pictures fairly fast…

“fascinating” isn’t it?

First Pictures taken by James Webb telescope arrive on Earth

finally… all that wait is over… here come the first images of the $10 Billion telescope of almost 17 years of build time… (first design 1999, redesigned in 2005)

planned / expected mission time 10 / 20 years

Hubble vs JWST – Carina Nebula https://www.youtube.com/watch?v=ridiA7-i_XU

JWST combined the capabilities of the telescope’s two cameras to create a never-before-seen view of a star-forming region in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), this combined image reveals previously invisible areas of star birth.

What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region known as NGC 3324. Called the Cosmic Cliffs, this rim of a gigantic, gaseous cavity is roughly 7,600 light-years away. https://webbtelescope.org/contents/media/images/2022/031/01G781KB7TTZM1YTP855D46C1S

The bright star at the center of NGC 3132, while prominent when viewed by NASA’s Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source. It has ejected at least eight layers of gas and dust over thousands of years. https://webbtelescope.org/contents/media/images/2022/033/01G70BGTSYBHS69T7K3N3ASSEB

web cms - wordpress still dominating - second comes no cms

https://w3techs.com/technologies/overview/content_management/

What is interesting, that 33% of all website creators, decide to not use any CMS at all (static HTML/manually editing it).

there is even a trend of creating cms inside wordperss, “cms inside the cms” so to speak, with plugins such as Enfold, elementor.com and wpastra.com

Mozilla Firefox is slow even if hardware acceleration is enabled?

Try enabling gfx.x11-egl.force-enabled in about:config to force the use of EGL¹ and then restart the web browser.
If this works, enabling layers.acceleration.force-enabled can boost your performance even more by enabling OpenGL alongside EGL. ²
This also works on Flatpak if the security permissions are correct (use Flatseal³ if needed).

Hardware Review - USB to NVMe adapter - Asus USB 3.2 Gen 2 Type-C M.2 NVMe SSD to USB Adapter also known as "Rog Strix Arion" vs Inateck M.2 NVMe 2 USB Adapter

the idea was:

• the user has computers, that allow for easy harddisk or NVMe swaps
  • installation X is on NVMe1, installation Y is on NVMe2
• or the user want’s to reinstall on a new harddisk, USB connecting the old harddisk, to restore files to the new harddisk

for this just as USB-SATA adapters an USB-NVMe adapter had to be found.

So gave the “Rog Strix Arion” by ASUS a shot.

• the pros:
  • makes NVMe work like an USB Stick
    • it says “initialize your blank ssd before use” (the terms NVMe and SSD start to get confusing)
    • but it is also possible to read an already “initialized” (partition table, formatted) NVMe
      • but it might be not the ideal choice for that use, more USB-Stick-NVMe kind of use
  • fast
  • solid heavy metal casing that distributes heat (those NVMe chips can become pretty hot)
  • nice LED light show
• cons:
  • open and closing it could be less of an effort

how to open this thing?

the user needs a pin.

hm…. and this won an Design Award in 2020?

Imho this makes things too complicated, as if there is no pin, there is no possibility to easily swap NVMes in and out of the NVMe-USB adapter.

benchmark performance:

USB 3.0 connected, it is fast. no doubt about it. ~430MBytes/sec kind of fast.

time <a href="https://dwaves.de/2020/11/13/gnu-linux-basic-harddisks-benchmarks-ssds-kingston-skc600512g-vs-samsung-ssd-850-pro-vs-samsung-ssd-860-evo-vs-samsung-ssd-870-evo-1tb-ntfs-vs-ext4-how-fast-are-virtual-harddisks/">/scripts/bench/bench_harddisk.sh</a>

sys 0m3,997s

So Asus planned for the user to install an NVMe and then use it like a USB Stick (no user will ever change the FlashChips of an USB Stick?)

also closing the device seems to be pretty hard… as the mechanism does not want to snap (again, this actually WON an design award? “The looks are great, who cares if it works” kind of award?)

Ok it is possibly, that the case closes properly with other NMVes, but the KINGSTON SA2000M81000G (some parts of it might be “too high”?) X-D

Inateck M.2 NVMe 2 USB Adapter

so bought the “inateck” adapter for half the price of the ASUS Adapter.

binary comment

• 10 Gbit/s
• USB 3.2 Gen 2
• Type C & Type A Cable included (nice!)
• while changing NVMes is also not sooo comfortable (detaching/attaching cooling pad and metal plate, but simply with the bush of an button (orange square above) it can be opened)
  • at least this time the NVMe “fit’s in”
• the speed is 2x twice as fast as the ASUS Adapter…

Un pote m’a prêté un bouquin traitant du chamanisme. C’est un recueil de textes traitant de ce sujet dont les premiers datent du XVIème siècle.

Parmi ceux-ci, le récit de l’ethnomusicologue Dale A. Olsen, en 1975, décrit de quelle façon les chamanes de la tribu Warao, au Venezuela, parviennent, durant les rituels de guérison, à modifier leur état de conscience à l’aide de la seule musique (chant, calebasse et crécelle), sans aucun recours à des substances hallucinogènes.

C’est donc, après négociations, muni d’un enregistreur professionnel de l’UCLA ainsi que d’un magnétophone portable grand public que le scientifique enregistra une séance dont, selon le chamane, une des finalités serait de détruire les machines de l’homme blanc.

Quelques semaines après la cérémonie, la machine professionnelle fut définitivement endommagée par des coulées d’acide provenant des piles et l’enregistreur amateur se mit à déchirer les bandes magnétiques.

Le chamane peut donc aussi bien, par l’entremise des esprits avec lesquels il entre en contact par la transe musicale, guérir que détruire.

Alors, cet été, restons bien vigilants, nous autres chamanes de l’écran et du clavier. Il ne faudrait pas que nos mélodies chamboulent la planète par maladresse ou inadvertance.

Mais je suis bien certain que vous saurez apporter joie et bien être plutôt que ruines et destructions.

On compte sur vous…

Hardware Review - USB to NVMe adapter - Asus USB 3.2 Gen 2 Type-C M.2 NVMe SSD to USB Adapter also known as "Rog Strix Arion"

the idea was:

• the user has computers, that allow for easy harddisk or NVMe swaps
  • installation X is on NVMe1, installation Y is on NVMe2
• or the user want’s to reinstall on a new harddisk, USB connecting the old harddisk, to restore files to the new harddisk

for this just as USB-SATA adapters an USB-NVMe adapter had to be found.

So gave the “Rog Strix Arion” by ASUS a shot.

• the pros:
  • makes NVMe work like an USB Stick
    • it says “initialize your blank ssd before use” (the terms NVMe and SSD start to get confusing)
    • but it is also possible to read an already “initialized” (partition table, formatted) NVMe
      • but it might be not the ideal choice for that use, more USB-Stick-NVMe kind of use
  • fast
  • solid heavy metal casing that distributes heat (those NVMe chips can become pretty hot)
  • nice LED light show
• cons:
  • open and closing it could be less of an effort

how to open this thing?

the user needs a pin.

hm…. and this won an Design Award in 2020?

Imho this makes things too complicated, as if there is no pin, there is no possibility to easily swap NVMes in and out of the NVMe-USB adapter.

benchmark performance:

USB 3.0 connected, it is fast. no doubt about it. ~430MBytes/sec kind of fast.

So Asus planned for the user to install an NVMe and then use it like a USB Stick (no user will ever change the FlashChips of an USB Stick?)

also closing the device seems to be pretty hard… as the mechanism does not want to snap (again, this actually WON an design award? “The looks are great, who cares if it works” kind of award?)
