It’s a confirmed news that Pine64 is considering a budget Linux smartphone running KDE Plasma.

On the desktop side, there is a new theme called “Yaru” that provides a different look and feel than what was provided by default in the prior Ubuntu 18.04 LTS release.
On the server side, Ubuntu 18.10 benefits from an updated Linux 4.18 kernel as well as support for TLS 1.3 encryption. The Ubuntu Server 18.10 integrates the OpenStack Rocky release, providing users with a stable version of the most recent open source OpenStack cloud platform release.
Networking configuration gets a boost in 18.10 as well with netplan.io, which is a network configuration abstraction utility.

Subject Linux 4.19
Hi everyone!
It’s been a long strange journey for this kernel release…
While it was not the largest kernel release every by number of commits,
it was larger than the last 3 releases, which is a non-trivial thing to
do. After the original -rc1 bumps, things settled down on the code side
and it looks like stuff came nicely together to make a solid kernel for
everyone to use for a while. And given that this is going to be one of
the “Long Term” kernels I end up maintaining for a few years, that’s
good news for everyone.
Codenamed "Cosmic Cuttlefish", 18.10 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs.The Ubuntu kernel has been updated to the 4.18 based Linux kernel, our default toolchain has moved to gcc 8.2 with glibc 2.28, and we've also updated to openssl 1.1.1 and gnutls 3.6.4 with TLS1.3 support. Ubuntu Desktop 18.04 LTS brings a fresh look with the community-driven Yaru theme replacing our long-serving Ambiance and Radiance themes. We are shipping the latest GNOME 3.30, Firefox 63, LibreOffice 6.1.2, and many others. Ubuntu Server 18.10 includes the Rocky release of OpenStack including the clustering enabled LXD 3.0, new network configuration via netplan.io, and iteration on the next-generation fast server installer. Ubuntu Server brings major updates to industry standard packages available on private clouds, public clouds, containers or bare metal in your datacentre. The newest Ubuntu Budgie, Kubuntu, Lubuntu, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu are also being released today. More details can be found for these at their individual release notes: https://wiki.ubuntu.com/CosmicCuttlefish/ReleaseNotes#Official_flavours intenance updates will be provided for 9 months for all flavours releasing with 18.10.

This recently happened with Transatomic Power (founded by Mark Massie and Dr. Leslie Dewan in April 2011), a Nuclear Startup that introduced a brand new design of its own Nuclear Reactor that is a lot more efficient than conventional ones.
Revisione 0.03
La nuova versione 0.18.08 del Firmware Arduino permette di realizzare l’Unità Didattica Il Semaforo Arduino.
L’Unità Didattica prevede di realizzare un modello di semaforo con tre LED colorati rosso, giallo e verde, collegati ai pin 2, 4 e 6.
All’avvio, se la sezione SEMAFORO nello sketch è attivata e la variabile semaforo_stato è automatico, allora si avvia il ciclo continuo di accensione e spegnimento con dati ritardi delle luci.
Seguirà l’ implementazione del comando
semaforo automatico|disabilitato|rosso|giallo|verde
da utilizzare nel consueto modo da remoto mediante canale USB .
Il codice sorgente relativo all’Unità Didattica viene attivato con
#define SEMAFORO
In questo caso vengono definite ed inizializzate le seguenti variabili:
#if defined(SEMAFORO)
String semaforo_stato = “automatico”;
// manuale|automatico|disabilitato
String semaforo_luce = “rossa”; // rossa|gialla|verde
int semaforo_durata_rosso = 3; // in secondi
int semaforo_durata_giallo = 1; // in secondi
int semaforo_durata_verde = 3; // in secondi
int semaforo_pin_rosso = 2;
int semaforo_pin_giallo = 4;
int semaforo_pin_verde = 6;
#endif
Quindi nella funzione setup()
#if defined(SEMAFORO)
pinMode(semaforo_pin_rosso, OUTPUT);
pinMode(semaforo_pin_giallo, OUTPUT);
pinMode(semaforo_pin_verde, OUTPUT);
#endif
E nella funzione loop()
#if defined(SEMAFORO)
if(semaforo_stato == “automatico”)
{
while(true) {
digitalWrite(semaforo_pin_rosso, HIGH);
delay(1000 * semaforo_durata_rosso);
digitalWrite(semaforo_pin_rosso, LOW);
digitalWrite(semaforo_pin_giallo, HIGH);
delay(1000 * semaforo_durata_giallo);
digitalWrite(semaforo_pin_giallo, LOW);
digitalWrite(semaforo_pin_verde, HIGH);
delay(1000 * semaforo_durata_verde);
digitalWrite(semaforo_pin_verde, LOW);
}

It was 2 years ago, at InnoTrans 2016 in Berlin that Alstom presented the Coradia iLint for the first time. The launch of the CO2-emission-free regional train that represents a true alternative to diesel power positioned us as the first railway manufacturers in the world to develop a passenger train based on hydrogen technology. And just two years later, at this year’s edition of InnoTrans 2018, the iLint enters into commercial service in Germany.

Ubuntu 18.10 will be released on 18th October 2018.

Unlike the previous releases, there will be no alpha or beta milestones. This will be replaced by ‘testing weeks’.
18.10 a short-term release and will be supported for nine months from its release i.e. July’19.
new features:
1. GNOME 3.30
2. New default theme
3. Better battery life for laptops (possibility)
4. Support for fingerprint scanner
5. Startup time boost and XDG Portals support for Snap applications
6. Android integration
7. Linux Kernel 5.0
8. 32-Bit support diminishing from flavors
9. Faster boot with new compression algorithms
What would you get if you crossed a gigantic Christmas tree ornament with an LED strip and Arduino/IMU control? Perhaps you’d come up with something akin to this colorful “RGB LED Ball” by James Bruton.

La moto elettrica che vedete in questo video e in queste foto si chiama Ethec, è un prototipo sviluppato dall’Università di Zurigo in Svizzera e da qualche giorno è sulla bocca di tutti per due motivi principali: fa 400 km con una sola carica.
Sarà la prima moto elettrica con recupero energetico in frenata.
La batteria è composta da 1260 celle a ioni di litio ed è raffreddata da un sistema termoelettrico: una cella di Peltier abbinata ad una sistema di iniezione olio. La capacità è di 15 kWh, con recupero energetico. I motori sono due, uno anteriore e uno posteriore, per un totale di 22 kW di potenza cioè circa 30 CV.


Battery Cooling: Battery cooling system with fan, pumps, a peltier element and an expansion tank. For a durable and powerful battery an efficient cooling is required. An air circuit discharges the heat from the oil circuit with the help of peltier elements. The oil circuit directly flows around the battery cells.

Battery Structure: Structure of battery including two modules from 1260 Lithium-ion-cells. In view, the regular arrayed circuit boards and perfectly placed temperature sensors, which control the cooling system precisely

Making difficult decisions can be tricky and stressful. This project will help you take off some of the pressure, instead letting your HalloWing-based Magic 9 Ball do the heavy lifting of your decision making!
Laboratorio di Informatica per Introdurre l’Interazione tra Computer Miniaturizzato e Realtà circostante.
Revisione 0.04
L’Unità Didattica si rivolge a chi desidera introdursi nel mondo dei Computer Miniaturizzati che interagiscono con la realtà circostante.
Il livello di difficoltà è basso, quindi è aperta a tutti i Gruppi di Interesse: dal bambino con il genitore all’insegnante che cerca stimoli da realizzare nel Laboratorio d’Informatica della sua Scuola.
La lezione introduce il popolare, soprattutto in ambito della Didattica dell’Informatica nelle Scuole, Arduino.
Ai partecipanti verrà presentato il Kit Semaforo Arduino con parti da utilizzare nell’esperienza di Laboratorio:
La prima parte dell’evento ha l’obiettivo di introdurre i nuovi materiali e metodi a chi non ne ha mai avuto occasione.
Quindi i partecipanti potranno realizzare un vero e proprio semaforo in miniatura, che fa scattare, ciclicamente, il verde poi un breve giallo ed infine il rosso.
La seconda parte dell’esperienza viene introdotta dal problema di come variare le temporizzazioni dei colori.
Il formatore mostrerà
I partecipanti quindi completeranno in autonomia l’esperienza di laboratorio e, completata l’esperienza, avranno ben aperta una nuova prospettiva di ricerca, che realizza un fondamentale tassello nella sua Formazione di Tecnologie Informatiche di Base.
Calendario
Numero partecipanti
Previsti da 15 a 30, con i quali ci sarà laboratorio ed interazione.

Another week, another rc.
Nothing particularly odd stands out on the technical side in the kernel updates for last week – rc4 looks fairly average in size for
this stage in the release cycle, and all the other statistics look
pretty normal too.

Here are some of the findings:
The kernel repository is at 782,487 commits in total from around 19.009 different authors. The repository is made up of 61,725 files and from there around 25,584,633 lines — keep in mind there is also documentation, Kconfig build files, various helpers/utilities, etc.
Zero Motorcycles Inc. is an American manufacturer of electric motorcycles. Formerly called Electricross, it was started in 2006 by Neal Saiki, a former NASA engineer, in Santa Cruz, California. The company is now located nearby in Scotts Valley.

Airdroid is a unique and useful application that lets you transfer files, send SMS messages and control your phone through your PC. It is available within the Google Play store and the iOS App Store and provides a useful alternative if you need to grab a file but don’t have a USB cable at hand. While Windows has a full rich client that allows easy access to the features, those of us on Linux have to use the web-based interface, but this doesn’t make the application any less useful.

Coming hot on the heels of the latest Linux kernel security update released by Canonical on Tuesday, the new Linux kernel live patch security update fixes a total of five security vulnerabilities.
La sigla General data protection regulations (Gdpr) che identifica la nuova disciplina europea in materia di privacy è stata beffardamente reinterpretata. L’acronimo è stato rivisitato in “Generally disclosing pretty rapidly” che lascia intendere che i nostri dati personali sono destinati a diventare pubblici abbastanza rapidamente.

A smart ring is a wearable electronics device with advanced mobile components that combine features of mobile devices with innovative features useful for mobile or handheld use. Smart rings, which are typically the size of traditional rings or larger, combine the features of a mobile device, such as the ability to make payments and mitigate access control, with popular innovative uses such as gesture control and activity tracking. Smart rings can communicate directly with smart phones or personal computers through a variety of applications and websites, and operate without the need to carry a smart phone, such as when interacting with back-end systems on the cloud through or performing standalone functions such as activity tracking. They typically do not have a display and operate by contextual relevance, such as by making a payment when near a payment terminal, unlocking an electronic lock when near the lock, or controlling home appliances when making gestures in the home. Some smart rings have physical or capacitive buttons to use as an activation mechanism, such as to initiate a gesture.

In 2013, the English firm McLear released the first smart ring for sale. The market is currently around $25 million.
Secure access control such as for company entry and exit, home access, cars, and electronic devices was the first use of smart rings. Smart rings change the status quo for secure access control by increasing ease of use, decreasing physical security flaws such as by ease of losing the device, and by adding two-factor authentication mechanisms including biometrics and key code entry.
Smart rings can perform payments and metro ticketing similar to contactless cards, smart cards, and mobile phones. Security of the transaction is equal to or greater than contactless cards. The first smart ring to be created with contactless payments was the NFC Payment Ring, which was mass produced and unveiled at the Olympics Summer Games at Rio de Janeiro in August 2016.
Replicating smartwatches, smart rings provide features including activity tracking (i.e. step tracking), heart beat tracking, and sleep tracking (through measuring heart beats and movements). The smart ring form factor contains enough space to contain the same components as smart watches. Due to size constraints, smaller components are typically used in current smart ring products in market, such as smaller and less accurate accelerometers, and smaller batteries leading to lower battery life than smart watches.
Smart rings provide social feedback to users and can be used to engage in the user’s environment in a way that other wearables and mobile devices do not permit. Ringly produces a women’s fashion smart ring which lights to notify the user when the user receives a text message, phone call, or other notification. This enables the user to be aware of the notification without having to constantly check her or his smart phone.
NFC (near field communication) technology is a great way to interact wirelessly with projects. With the RFID/NFC Smart Ring your ring can communicate with your smart phone/tablet, computer, or much more! Contains two MiFare Ultralight C – NTAG 213’s with 144 bytes of read/write memory. One is on the ‘inside’ of the ring towards the palm, the other is underneath the jewel. You can use tags to launch apps, unlock your phone, transmit a URL, control an Arduino, etc.

Dubbed “Almería” after the host city of the GUADEC (GNOME Users And Developers European Conference) 2018 event that took place in early July, GNOME 3.30 updates numerous of its core apps and components by adding new features and enhancements to make your GNOME desktop experience more pleasant.
While many Linux users have a strong preference for a window manager of choice, for those just making their way over from Windows or Mac, it may be hard to understand what a window manager is, or that it’s even something you have a choice in. A window manager is the part of your system that dictates how individual application windows look, and how you can interact with, control, and arrange them.

I love it when the opportunity to combine music and coding comes together. I’ve worked on a few personal projects related to music, from making music with network traffic to an auto-accompaniment system for electronic drums. More recently, my wonderful wife gave me a beautiful, programmable music box for my birthday. You punch out music notes on a card and crank it through the music box to play a tune.

Zebpay, which is a big cryptocurrency exchange from India, has recently notified its users that it would not be able to let its users withdraw their tokens for INR if it did not have a supporting bank in a document titled “Prohibition on dealing in Virtual Currencies”.

After the notice was sent out, all the major cryptocurrencies, ranging from Bitcoin to Ethereum and Ripple were down by more than 10% in what is being called the India Flash Crash by some people.

Cryptocurrency lending platforms work by connecting borrowers to a network of lender registered on the platform. In this case, borrowers receive their cryptocurrencies back once the borrower pays the loan. Most of the platforms have loans that are backs by assets, including real estate. But other platforms let users take loans that are backed by Bitcoin or other virtual currencies.
In the world of cryptocurrency, most people simply assume that the best way – and perhaps the only way – to make money is by day trading on currency exchanges. However, that’s simply not true. In fact, there are dozens of ways to earn a few bits of the cryptocurrency of your choice; one of the most novel ways is to run a master node.

The rise of cryptocurrencies has been undeniable. With the rising trade value of bitcoins and ethereum it can be clearly seen that that the era of cryptocurrencies is upon us. In fact, financial institutions all over the world have claimed that Bitcoins are indeed a better investment than gold and other precious metals at this point in time. It is also interesting to note that in 2017, the United Nations sent financial aid to Syrian rescue camps via means of cryptocurrency (so as to minimize any internal losses).
