Hi all, just a blatant advert for a forthcoming event in the next few weeks.  Stable coins are cryptocurrencies that are designed to be more "stable" than normal cryptocurrencies as they are pegged to an underlying asset (fiat currencies, gold, etc).  

"In the Stablecoins Fundamentals masterclass, you will learn about the different types of stable coins, the risks and features of the stability mechanisms, their use cases, the underlying technology,  and more from Industry Expert Dr. Markus Franke, Partner at cLabs, working on the Celo platform."


Online; register here; 101 Blockchains - Stablecoins Webinar

Some nice tools for the shell command line; broot, funky, fuzzy finder, mcfly, gitupdate and a few more --> command line tools
Also, I found this video from way back in the day; You tube - AT&T Archives: The UNIX Operating System

Maybe as a front end for this new Co-Pilot code assistant thing.  
Fair bit of discussion about the merits of this.  Now imagine the annoyance if your IDE then pops up a clippy offering to help "improve" your code - oh please no.

Hillend is just north of Edinburgh, over the river seven on the fourth bridge, and head east towards Dalgety Bay.  A nice part of the world, you just have to avoid the odd drunken sailor as it's way too close to the Rosyth naval base!    

The odd thing is I once interviewed for a contract at this site.  The interview quite quickly became very informal, but ultimately I was unsuccessful.  Turns out for that particular role they were really after a "real-time" C programmer who understood avionics and also held the required clearances.  For the bit of java, they did, I recall they using the eclipse modeling framework.  

The rate for the role was a lot more than £45K, somewhere between £350-£450 a day if I remember correctly.  That was of course before all of this IR-35 nonsense.  

defined and structured engineering lifecycle processes with formal gate reviews and a culture of measurement

- so a good old waterfall project then!

Oh, but the future and solution is going to be nuclear, but fusion [atomic nuclei are combined] rather than the existing fission [splitting of a large atomic nucleus].  They seem to be making good progress but still a few years away [Firm close to 100M degree fusion.

As for the pipeline, I believe they have now paid the ransom, mostly lightly to some commie country who sponsored the hacking.  From what little I recall about shipping, the US has a law called the Jones Act which is deigned to ensure that oil can be shipped locally between ports in the event of a crisis.  In effect it means that only a US based tanker can operate between two ports in the states.

Reminds me of the term "CandyGrammar", from the Jargon Lexicon

candygrammar: n.
A programming language grammar that is mostly syntactic sugar; the term is also a play on ‘candygram’. COBOL, Apple's Hypertalk language, and a lot of the so-called ‘4GL’ database languages share this property. The usual intent of such designs is that they are as English-like as possible, on the theory that they will then be easier for unskilled people to program. This intention comes to grief on the reality that syntax isn't what makes programming hard; it's the mental effort and organization required to specify an algorithm precisely that costs. Thus the invariable result is that ‘candygrammar’ languages are just as difficult to program in as terser ones, and far more painful for the experienced hacker.

101 Blockchains are holding a free online conference to talk about blockchain/decentralized ledger technologies within finance.    

This 101 Blockchains Virtual Conference gathers some of the best international experts to share opinions, current practices and challenges, offering advanced use cases on Distributed Ledger Technology and Digital Assets with a focus on payments and trade finance.

The use of blockchain is gaining traction and new applications are emerging. Our 2021 virtual conference brings you innovative cases in global payments and trade financing.

Join us to hear how specialised technology providers are leveraging DLT across payments and trade finance and in support of incumbent financial institutions, their counterparties and clients.


Registration is free at 101 Blockchains Trade Finance Event 22nd April

101 Blockchains is hosting a free event tomorrow, Decentralising the Identity in Blockchain with TrustID.  

The event is online at 16:00 GMT (11:00 ET / 17:00 CET) and requires pre-registration - 101 blockchains event registration. .    

The event is free, but they will try to sell you their other courses and membership ["there's no such thing as a free lunch"].

How do you know that they are not stored with some sort of encryption?  Agreed it's better to use a hash function.  I'm not familiar with SAP but I'll sort of expect them to comply to some sort of security standard.

Used to develop backend smart contracts that facilitate interactions between businesses (or business units).  It is based on the internet (of value) but nothing to do with frameworks like Spring.  However, there is nothing to stop you from developing a web application alongside blockchain technology - something like Corbeans looks to offer integration.  

Funny thing is I did ask about blockchain at recent (virtual) SpringOne conference.  The question was totally ignored ;-)  
PS You know that Spring is much more than a "web application framework?"

Yeah, sorry it's Mackem.  But as you pointed out, much to their annoyance most folk in the region get called "Geordies".  Poor monkey being taken' to mackem-land and hung as it could not understand them - oh the irony ;-)

Yes, I think I can speak Geordie and also English however like most who have worked away; sounds too "posh" in the toon (Newcastle) and too "broad" everywhere else.    

Was robocop as bad as the prince of darkness?  At a local fish and chip shop; "Can I also have a tub of that guacamole [avocado dip] please?"  - "You what?... you want mushy peas?"

For some sort of clarity let me outline some of the different types of blockchain/decentralised ledger technology systems and the business case for them.  

Open or closed would describe who can view (or read) the data.  An open system would show all the data to anyone, a closed system would restrict who can see this data.
Public or private would determine who can write (or create) data.  For public this would be anyone, private systems would add restrictions.      

So an open and public systems tend to be used for cryptocurrencies that offer a store of value (bitcoin), payment services (ripple), or programmable networks (ethereum/de-fi).  Data is identified by using a public address but owned by the person who holds the private key.

A closed and private network like Corda [and Hyperledger Fabric] would require some sort of identity access management.  Typically participants only share a subset of their data with relevant customers as it may be commercially sensitive (Alice may not want Oscar to know that Bob pays less for a widget).  Trade finance, supply chain, or any system which would benefit from "trusted" shared data would be the typical use case.

An open and private system would suit the publication of laws, publicly viewable tax returns, public announcements, and similar.  Closed and public would suit voting use cases.  

...and then there are central bank digital currencies (CBDC) - but that's a whole new topic!

Hope this helps a bit, for a nontechnical introduction I'll recommend the free Enterprise Blockchains Fundamentals course from 101 Blockchains.

The thing is that particular monkey did a decent job, and got himself re-elected twice.  He did, unlike the US monkey, stop all the monkey antics (like getting drunk and thrown out of football matches) once in public office.  I believe the post was removed before he could be elected for a third term, I guess they didn't like his independent stance.  Also, folks in the UK were cooking "Bitter Orange Tart" as it was yesterdays (Jan 20th) recipe of the day - no idea why.

The guy seems to have slowed down, maybe to help others understand him better.  

It's fun being bilingual as you can quickly switch into an uncomprehensible language to confuse those (southerners) from outside the area.  Or just drop the odd native word/phrase in for a  delayed effect.  Had never heard the term "pit‑yacker" before but sort of fits with the other terms for the regions ("smoggy", "monkey hanger*", "macum", "sand dancer" etc).        

I did find that in the US they tend to think you are speaking Welsh.  

*During the Napoleonic wars, they really did hang a [poor] monkey.  More recently they elected a monkey mascot as a town mayor, then kept re-electing him.
