Check out my #AsicBoost Block Explorer at asicboost.dance 🚀

@minerswins Grau bedeuten, dass entweder Open Street Map keine Adresse in Wabe dieser bekannt ist (passiert vor allem in ländlichen Gebieten) oder, dass Easybell dort tatsächlich kein VDSL anbietet (unwahrscheinlich). Frag sonst mal die Easybell API direkt (unten auf github.com/n-thumann/easy…)

@n_thumann Verstehe ich das richtig, zu den grauen Waben ist (noch) nichts bekannt? Ich werde es testen, lt. Telekom soll der Techniker spätestens die nächsten 2h vorbeikommen, noch ist die Leitung tot.

Soo FritzBox ist angeschlossen, Morgen kommt der Telekomtechniker vorbei und schaltet den 1und1 Anschluss. Hoffentlich funktioniert das mit dem Versatel Netz und ich lande nicht in AS3320 Ich werde berichten...

@Moin_EWE @nico22de Zwei Leute vom Support sagen da was anderes: Die meinten heute morgen noch, dass sich die Implementierung von IPv6 in der Realisierung befinde, man aber zum jetzigen Zeitpunkt noch keine Zeitpläne oder technische Details veröffentlichen könne. Was denn nun? 👀🤔

Huhu @Moin_EWE, ich glaube es wird mal wieder Zeit: wie sieht es denn mit IPv6 für die Glasfaserkunden aus? Gibt es da mal was neues?

Die COVID-19-App der Telekom soll Patienten einen schnellen Zugang zum Ergebnis ihrer Coronatests verschaffen. (pollicip) heise.de/ct/artikel/c-t…

Die COVID-19 App der @deutschetelekom und BS Software Development ist eine sehr gute Idee! Die aktuelle Umsetzung, Testergebnisse direkt aufs Handy geschickt zu bekommen, aber sicherheitstechnisch eher holprig, was das Ausspähen ermöglicht. n-thumann.de/blog/schwachst…

Habe gerade mein Projekt IPTV-ReStream freigegeben. Es ermöglicht das Empfangen von source specific Multicast RTP-Streams (z.B. Telekom MagentaTV) durch weiterleiten über HTTP an entfernten Clients 👏🏻 github.com/n-thumann/IPTV…

If you’re not using the latest Parallels Desktop version to work with VMs, you probably noticed that more recent Linux Kernel versions are not compatible with your older version. I’ve found a pretty easy workaround: n-thumann.de/blog/running-n… 😊

@rstelzle @UKParliament File ID seems to be wrong, try votes.parliament.uk/Divisions/Down… :)

@UKParliament For example when trying to download the result of the recent vote on the withdrawl agreement (votes.parliament.uk/Votes/Commons/…), I get a .csv regarding some energy bill from 2016. 2/2

Hey @UKParliament, I think the data access for division results on your website is somewhat broken. When trying to download in .csv format I only get to download the results from some random other vote (havent found a pattern yet). Downloading the .txt or the .png works fine. 1/2

About the "security issue" on #VLC : VLC is not vulnerable. tl;dr: the issue is in a 3rd party library, called libebml, which was fixed more than 16 months ago. VLC since version 3.0.3 has the correct version shipped, and @MITREcorp did not even check their claim. Thread:

I just released my security advisory about the vulnerabilities (CVE-2019-12581 & CVE-2019-12583) in Zyxel devices, I‘ve found: n-thumann.de/blog/zyxel-gat… ✌🏻 The “Free Time“ feature basically allows anyone to access your network 😬 Read Zyxels statement: zyxel.com/support/vulner…

Great talk on Bitcoin hardware wallet security by @nedos @StackSmashing @cryptotx on #35c3 👏🏻 media.ccc.de/v/35c3-9563-wa… & wallet.fail Any eta of your #F00dbabe video @LiveOverflow?

Great article on the current circumstances of #AsicBoost by @CarpeNoctom 🙌🏻 @CarpeNoctom/the-omnipresence-and-resurgence-of-asicboost-in-the-setting-of-rising-segwit-adoption-c6afda06c562" target="_blank" rel="nofollow noopener">medium.com/@CarpeNoctom/t…

After 1000 version-rolled block in the Bitcoin chain, I am happy to announce that there is a Bitcoin Cash site of my AsicBoost Block Explorer available now at cash.asicboost.dance!

After exactly two years it’s time to say farewell to my @torproject relay 👋🏻 In that time it pushed ~200TB and up to 845GB/day. There was a 0.13% probability that you were using it as an exit or 0.025% as a guard/middle.

@Chris21124 @WhalePanda @AntPoolofficial Partly correct: Overt AsicBoost is completely unaffected by SegWit while covert AsicBoost incentivize miners to refuse SegWit txs or mine small blocks.

@WhalePanda @AntPoolofficial I've heard that SegWit and ASICBoost don't work well together, can anyone confirm?

After mining almost all empty blocks in the beginning of the month, @AntPoolofficial has now completely stopped mining Segwit transactions. reddit.com/r/Bitcoin/comm…

Congrats to @btccom_official for mining their first #AsicBoost block 🙌🏻 asicboost.dance

@StevieJarosz No quite: One or more SegWit txs requires a miner to include a witness commitment in the cb tx. This makes tx shuffeling more expensive, as the merkle tree has to be recalculated as well. Fun fact: Even Bitmain uses SegWit in its (maybe AsicBoosted) blocks

Great info, my understanding is that we need at least 1 segwit transaction per block to prevent covert-asicboost by a miner

@bradmillscan @Excellion Covert AB requires to generate many merkle roots. One can do that by changing the extranonce (located in the Coinbase tx) or shuffling merkle root branches/tx. The more levels a merkel root has, the higher the difficulty of these methods. So less txs = less hashing required

@Excellion ELi5 on why it's easier or were you kidding

It’s easier to covert AsicBoost with empty blocks.

@BeautyBubble Just a coincidence as I was searching for AsicBoost tweets at that moment 😊

@n_thumann Never in all of twitter have I witnessed a "like" before at that speed.

Dear @n_thumann Hey you. What re-tweet auto poster are you using --- it is like super fast. So, please share. Thank you. Sincerely, sent ~Beauty
