How to Android without Google

Icon

This guide shows how to install LineageOS without GApps with the help of signature spoofing and microG, so that you can have Push Notifications, Location Services and the like, without needing to have Google Play Services installed (without Google-anything for that matter).

It was made possible by the hard work of creators, maintainers and community around LineageOS, microG, XPosedFramework, F-Droid, Yalp Store and many others.

Exactly what it says on the tin.

Linux Solutions: Snappy, Flatpak, and AppImage

It wasn't all that long ago the idea of binary packages were seen as salvation from having to compile software packages for one's Linux system.

In 2018, we've jumped ahead even further, with distro independent package installation solutions. In this article, we're going to look into three rising stars in this area: Snappy, Flatpak and AppImage.

AppImage is a software disk image that just works

I'm a huge fan of AppImage as you simply make the individual application you wish to run executable, then double click it. AppImages are just that simple. According to their website, the idea is that you get the software directly from the author of said program. Using the AppImage format, installing an application can feel similar to how one might do it with Windows.

The advantage of running an AppImage is that there is no need for sudo, root or even the need to be bothered with system dependencies. You're basically mounting a disk image, similar to how one might mount disk images in OS X.

Perhaps the biggest advantage to running AppImages is that you're running an application that can be removed by simply deleting a single file. This single file/disk image approach is both great and a hardship depending on how you look at it. AppImages are great in that they're easily distributed and simple to run.

The downside of AppImages are that even when you get the software directly from the author's website, you still don't really know if the application has been tampered with. This problem of trusting software is best demonstrated with what happened to OS X users and the application known as Transmission. This application allowed ransomware to infect those individuals who ran the application on their Macs.

So as much as I like AppImages, I take issue with the bold print statement that AppImages are to be trusted absolutely. Fact is, they're just disk images and instead we need to trust the distributor of each individual AppImage. Thankfully if one chooses to run an AppImage within a sandbox, this prevents things from getting out of hand should the downloaded AppImage become exploited on the source website.

Flatpak provides isolated runtimes

Updates and applications installed by Flatpak are handled by individual runtimes. The idea is that this provides more streamlined package handling than running typical Linux package updates. Now here's where Flatpak shines - it's designed for desktop Linux distros. So the applications that are distributed with Flatpaks are going to be designed for desktop Linux users. This is a characteristic also found with AppImages, however Flatpaks differ in that they allow for individual application updates.

Flatpaks share similarities with Ubuntu PPAs in that they're using individual repositories for application installation and updates. I'll be first to admit that I honestly don't love this element of Flatpaks as it's time consuming to have to chase down individual repos. On the positive side, however, it does provide a better system for installation/updates as it's distro independent.

Another consideration is that installing the framework for Flatpaks requires the installation of needed components to make the Flatpak available software installable. The irony takes place with distros such as Ubuntu whereas you must add an Ubuntu PPA for the Flatpak framework. In short, install a PPA repository to install a framework to install Flatpak repositories. While it's not difficult to do this, it is a bit redundant.

The benefit of running Flatpak installed applications is that you can run the latest software on any distro you choose. Additionally, to curb the headache of seeking out individual Flatpak repos, Flathub's Application section makes finding software easy.

Flathub provides the ability locate software in one location, even though historically Flatpaks aren't located in a singular location. It's actually a great idea and it makes using Flatpaks a lot more appealing. Perhaps most importantly, Flathub's software categories are packed full of tons of software to choose from.

To repeat an item from above: Like AppImages, Flatpaks are designed for Linux desktops. This is an important consideration as we roll into the next section of this article.

Snap Packages are a compressed file system

Snap packages are a packaging concept created by Canonical and designed for Linux and IoT (internet of things). When you arrive at the Snapcraft website the first impression you find yourself with is that Snaps put the developer ahead of the end user. I don't mean that as a negative statement, however the Snaps web presence backs up my statement completely. The two buttons on the front page are "Build your first snap" and "Get started using Github."

Both button links mentioned above assume you're a developer. This differs substantially from the front page of the Flatpak. The Flatpak front page is dedicated to getting Flatpak software onto the PCs of end users. Snaps only offers end user solutions if you look to the very top navigation bar and click on store. Once you click the store link, you're presented with available Snaps to install onto target PCs and servers.

Snaps also share similarities with AppImage in that you're mounting a software image vs installing software. Another benefit with Snaps is being able to roll back to an earlier version of software. Additionally, updates are made easy since Snaps share a single repository.

The biggest downside some people find with Snaps is the fact it provides a centralized packaging format that Canonical controls. Granted, Snaps are available across multiple distros, but the control of available Snaps remains in a single location. It's also worth noting that notable open and closed source software is welcome in Snap's repository.

One last important point with Snaps is that they're not limited to the Linux desktop as I mentioned previously. They're also designed to provide packaging solutions for IoT (internet of things). This is the biggest difference between Snaps and both Flatpak and AppImage. Snaps are heavily focused on IoT with Linux being an added bonus.

Which packaging type is best for Linux?

After looking at the differences and advantages of each packaging type mentioned above, we're left wondering which one is best. In terms of simplicity, I'd argue that AppImage wins this one. But if you want to be able to update your software using one of these packaging formats, then Flatpak or Snaps make more sense.

One approach might be to try out each of them and see which packaging type has the user experience and the software titles you're looking for.

What say you? Do you have a preference? If so, what is your rationale as to your choice of software packaging. Hit the Comments, let's hear your perspective.

USB 3.2, USB Type-C & SoundWire Updates Head Into Linux 4.18

Greg Kroah-Hartman has begun submitting the v4.18 pull requests for the multiple subsystems he maintains within the Linux kernel.

First up are the

USB updates

for Linux 4.18. With the USB updates there is continued work on bettering the Linux kernel USB Type-C support, namely around the

Type-C Port Manager

(TCPM) that was merged to the mainline kernel last year. Greg KH noted that the Type-C code is almost ready to leave the staging area of the Linux kernel.

Also queued as part of the Linux 4.18 kernel are

some early bits for USB 3.2 support

though it doesn't look like any USB 3.2 controller support is ready for Linux 4.18, this is just the infrastructure prepping around this USB specification published last year.

Greg also sent out the

char/misc updates

. On that front there are more updates to

SoundWire

, the new simple audio stream subsystem that is a MIPI specification and added back into Linux 4.16. There is now support for SoundWire stream management, port management, master/slave port programming, stream configuration APIs, and other additions.

A new driver that is part of the char/misc pull request is the IBM Virtual Management Channel Driver (VMC). The IBM VMC driver is for POWER hardware and is used as a virtual adapter with the PowerVM platform for message passing.

Greg also sent out the

driver core

and

TTY/serial

patches, but nothing too exciting on that front for Linux 4.18. He hasn't yet sent out the staging subsystem updates.

Intel's 28-core 5 GHz CPU: coming in Q4

Icon

Alongside the launch of Intel's first 5 GHz processor, the 6-core Core i7-8086K, Intel today also showcased a 28-core single socket machine also running at 5 GHz. The system on display scored 7334 in Cinebench R15, and Gregory Bryant (SVP and GM of Intel Client Computing Group) explicitly stated that it would be coming in Q4 this year.

No other details were provided, however for it to exist in a current platform, this new processor would likely be in LGA2066 (X299) or LGA3647 (the server socket). Intel technically already makes 28-core monolithic designs in the Intel Xeon Scalable Platform with the Xeon Platinum 8180, which is a $10k processor, which runs a lot slower than 5.0 GHz.

This sounds like an absolutely insane processor few of us will ever get to enjoy.

La FIA porta i kart elettrici alle prossime Olimpiadi giovanili

La conferma è arrivata direttamente dal presidente dell’organo di governo sportivo, Jean Todt, in occasione dell’ultima FIA Sport Conference che si sta svolgendo in questi giorni a Manila. Il numero uno della Federazione ha dato l’ufficialità dell’approdo dei kart elettrici ai giochi che si terranno nel paese sudamericano nell’autunno 2018. L’e-kart rappresenta non solo una nuova opportunità in termini di sviluppo degli sport motoristici, ma dimostra anche che il mondo sta cambiando e che dobbiamo essere leader di questo cambiamento” – ha dichiarato il transalpino – “Il karting sarà presente anche in occasione delle Olimpiadi della Gioventù a Buenos Aires, in Argentina, il prossimo ottobre”.

Todt ha poi aggiunto che si tratta indubbiamente di un “significativo passo avanti per la FIA” nel suo processo di riconoscimento, iniziato nel 2012, da parte del Comitato Olimpico Internazionale. Il vice presidente della Federazione, Graham Stoker, che tramite l’opera del suo sottocomitato per l’innovazione si è prodigato per fare includere il kart ai prossimi giochi olimpici riservati ai giovani ha fatto notare che grazie a questa mossa, la FIA – “ha un’opportunità per cambiare completamente l’approccio al motorsport in tutto il mondo in qualità di Federazione Internazionale”.

A guidare per una prima dimostrazione il mezzo elettrico che scenderà in pista alle olimpiadi argentine sarà l’attuale presidente della Commissione Kart della FIA, Felipe Massa, che si cimenterà in un test a margine della conferenza in corso a Manila. Il veicolo è stato sviluppato dalla Bosch insieme costruttore tedesco specializzato in telai di kart Mach1, i quali hanno interagito con la Federazione nella messa a punto. Le caratteristiche tecniche riferiscono di un powertrain dotato di 20KW di potenza e che sviluppa 300Nm di coppia servendosi di una batteria da 48V.

Google Quits Selling Tablets

Google has quietly crept out of the tablet business, removing the "tablets" heading from its Android page. It was there yesterday, but it's gone today. TechCrunch reports: Google in particular has struggled to make Android a convincing alternative to iOS in the tablet realm, and with this move has clearly indicated its preference for the Chrome OS side of things, where it has inherited the questionable (but lucrative) legacy of netbooks. They've also been working on broadening Android compatibility with that OS. So it shouldn't come as much surprise that the company is bowing out. Sales have dropped considerably, since few people see any reason to upgrade a device that was originally sold for its simplicity and ease of use, not its specs. Google's exit doesn't mean Android tablets are done for, of course. They'll still get made, primarily by Samsung, Amazon and a couple of others, and there will probably even be some nice ones. But if Google isn't selling them, it probably isn't prioritizing them as far as features and support. Android Police was first to break the news.

Huawei Announces EROFS Linux File-System, Might Eventually Be Used By Android Devices

Huawei's Gao Xiang has announced the EROFS open-source Linux file-system intended for Android devices, but still at its very early stages of development.

EROFS is the company's new approach for a read-only file-system that would work well for Android devices. EROFS is short for the Extendable Read-Only File-System and they began developing it with being unsatisfied with other read-only file-system alternatives.

EROFS is designed to offer better performance than other read-only alternatives while still focusing upon saving storage space. As part of EROFS is also a compression mode pursuing a different design approach than other file-systems: the compression numbers shared in today's announcement on both server hardware and a Kirin 970 are compelling for being in the early stages of development.

EROFS is still very much a work-in-progress and the on-disk layout format has yet to be finalized. It will likely take several months at a minimum before Huawei potentially seeks the inclusion of the code into the mainline Linux kernel.


Don't look for EROFS appearing on Android devices in the immediate future, it's still in the very early stages of development.

The user-space bits for making a EROFS file-system will be published once they clear their internal review, but for now the initial five thousand lines of kernel code making up this read-only file-system driver can be found for review and discussion on the

kernel mailing list

PUBG’s new update is making some big changes to grenades

Try not to get burned

The newest update for PlayerUnknown’s Battlegrounds is here and it’s bringing a few big improvements to items most people don’t use often, as well as some much needed performance upgrades.

The biggest change with this update — called patch 1.0 update 14 — are tweaks to several different types of grenades. Frag grenades are getting a little buff to their damage, as well as a radius around them that does damage based on how close a player is to the explosion. Meanwhile, stun grenades will now prevent players from seeing, hearing or being able to shoot accurately if they are hit by the grenade’s flash. Finally, Molotovs are getting a whole lot more dangerous with a bigger area of effect and fire that will spread across wood surfaces for a limited amount of time. According to developer PUBG Corp., these changes were made to help keep frag grenades strong, while making stun grenades and Molotovs a little more appealing to use.

But grenades aren’t all that’s changing in this update. PUBG Corp. has also done some work to the game’s back end to improve performance. A few of these changes are aimed at improving the game’s frame rate, but the most meaningful improves its network performance and, according to some players, may have almost doubled the server tick rate. What all this means in practice is that PUBG should feel a lot better to play after this patch with everything moving smoother and with significantly less lag.

For a full look at what’s changed in PUBG update 14, you can check out the official patch notes.

Valve Patches Security Bug That Existed in Steam Client for the Past Ten Years

Valve developers have recently patched a severe security flaw that affected all versions of the Steam gaming client released in the past ten years. From a report: According to Tom Court, a security researcher with Context Information Security, the one who discovered the flaw, the vulnerability would have allowed an attacker to execute malicious code on any of Steam's 15 million gaming clients. In the jargon of security researchers, this is a remote code execution (RCE) flaw because exploitation was possible via network requests, without needing access to the victim's computer. Court says an attacker was only required to send malformed UDP packets to a target's Steam client, which would have triggered the bug and allowed him to run malicious code on the target's PC.

Un network di account sospetti ha spinto la campagna sui social contro Mattarella 

Un network di “account sospetti” su twitter, strutturato e con movenze organizzate, ha prodotto una forte spinta artificiale a tre hashtag di propaganda (a volte con contenuti anche di propaganda pesante e di minacce) contro il presidente della Repubblica Sergio Mattarella, nei due giorni più caldi della crisi per la formazione del nuovo governo, di domenica e lunedì scorso. Sono i giorni in cui il Movimento cinque stelle gridava all’impeachment contro Mattarella, anche se gli account di questo network non presentano evidenze riconducibili a un partito ufficiale. Gli account non mostrano neanche segni di interferenza straniera, appaiono piuttosto frutto di farm italiane. La sostanza, comunque inquietante, è che dei network si muovono per attaccare online la presidenza della Repubblica, contribuendo a invelenire e esasperare una situazione politica già molto difficile. 

 

È quanto emerge da un report di due informatici, Andrea Stroppa e Danny di Stefano, che hanno utilizzato un algoritmo per individuare la propaganda digitale (da loro già impiegato - quasi identico - durante il World Economic Forum di Davos 2018) per analizzare tre hashtag: #mattarelladimettiti, #impeachment e #impeachmentmattarella. L’analisi ha individuato 360 account. È stata condotta dal 27 maggio (alle ore 21.50) al giorno successivo (alle 14.30). «Non parliamo di bot o troll - scrivono gli autori - ma di “account sospetti”: questo perché in uno scenario così altamente complesso, indicare un account come bot o troll è difficilmente dimostrabile, in particolar modo in un ecosistema di propaganda digitale molto discusso». La ragione principale è semplice: «Se indichiamo l’account @marioRossi232323 come bot, perché le sue caratteristiche del profilo e i suoi contenuti o azioni dimostrano automazioni, chi gestisce il presunto bot, un essere umano, potrebbe prenderne il controllo all’istante e iniziare a usarlo in prima persona, provando quindi a dimostrare l’infondatezza di una ricerca». Account generati da un software possono poi tranquillamente “animarsi”, ossia essere operati da umani. 

 

Sono stati quindi usati quattro criteri in questa analisi, confermata alla Stampa anche da una terza parte: composizione del nickname e caratteristiche del profilo, proporzione (ratio) tra following e followers, argomenti trattati, analisi di network. Per esempio, un account normale di solito tende ad avere più follower rispetto ai following, o almeno non in modo sproporzionato. Il report dunque considera solo gli account che, per ogni follower, hanno invece seguìto almeno 5 persone. Le conclusioni a cui arrivano i due informatici sono queste: è stata in corso contro la presidenza della Repubblica «una azione coordinata di digital propaganda, ben studiata in modo da potersi agevolmente nascondersi in mezzo agli account legittimi. Non ci sono evidenze che questi account appartengano ufficialmente a partiti politici come Lega Nord e M5S». Né che la campagna provenga dall’estero. «È però allo stesso modo evidente che in Italia esiste una rete in grado di manipolare eventi politici e sociali, con capacità di poter amplificare fenomeni e farli diventare virali». 

 

L’analisi non si sofferma volutamente su «account importanti» (il numeor di follower di per sé non dice granché, sono molto più interessanti il network, e eventualmente i livelli e il tipo di engagement), ma su quella che è - diciamo così - la loro «base sottostante» di piccoli account sospetti. Da questo punto di vista, le disinfo ops o le ops di black propaganda stanno lievemente mutando forma, nell’ultima stagione, almeno in Italia, cercando di polverizzarsi e mimetizzarsi il più possibile con account naturali dei social. Eviteremo quindi di citare gli account del report Stroppa-Di Stefano, ma solo alcuni dei loro contenuti, che vanno dalla satira pesante («Mattarella ha un würstel al posto del cuore #impeachment») all’insulto («traditore della patria» è il più tenue) o alla violenza verbale («Così #Mattarella butta nel cesso il voto di 15 milioni di italiani. Perché secondo lui la sovranità in Italia appartiene alla #UE e alla #Merkel e non al popolo italiano»), alla minaccia («Don’t Fear The Reaper» - «non temere la Grande Mietitrice», cioè la morte, e sotto, una foto di Mattarella in camice ospedaliero e la scritta «do not intubate do not reanimate»). Inutile procedere oltre, era solo per dare una vaga idea. Augurano o minacciano di morte Mattarella. 

 

Il punto centrale - bisogna ripeterlo - è che secondo i due informatici si tratta di un preciso network: il sample analizzato è relativamente piccolo, ma potrebbe essere più largo (i criteri per l’inclusione sono stati molto selettivi, spiegano gli autori). Molti account del network sono sotto «limitazione temporanea» da parte di twitter, o subiscono restrizioni: segno che sono stati oggetti di ripetute segnalazioni, o sono sotto l’attenzone della cybersecurity dell’azienda. Altri presentano, anche a prima vista, una congiunzione di interessi politici che è poi alla base di alleanze reali attuali, tra sovranismo, ultranazionalismo, tematiche sociali (nazionali e sociali), temi anti-establishment. Una politica parallela è insomma pronta a essere scatenata e rialzata, se davvero si andasse al voto bisognerà tener d’occhio le reti, dove contenuti sovranisti, fortemente nazionalista e anticasta si sono sposati ormai da tre anni, e invocano con modi brutali la rivoluzione legastellata.

Intel Core i7-8086K Listed, First 5.00 GHz Processor


Intel is commemorating 40 years of its 8086 processor, the spiritual ancestor of the x86 machine architecture that rules modern computing, with a special edition socket LGA1151 processor, dubbed Core i7-8086K. The chip appears to feature a nominal clock speed of 4.00 GHz, with a maximum Turbo Boost frequency of 5.00 GHz, making it the first mainstream desktop processor to hit the 5.00 GHz mark, out of the box.

The Core i7-8086K is more likely to be based on a special bin of the 14 nm, 6-core/12-thread "Coffee Lake" silicon, rather than being something next-gen or 8-core. The retail SKU bears the part number "BX80684I78086K." The chip will be compatible with Intel 300-series chipset motherboards. Pre-launch listings put its price around $486, which is along expected lines, as it's 70-100 EUR pricier than the i7-8700K. Intel could unveil the Core i7-8086K at the 2018 Computex (specifically on the 8th of June), alongside the first motherboards based on its Z390 Express chipset.

Microsoft Developing a Tool To Help Engineers Catch Bias in Algorithms

Microsoft is developing a tool that can detect bias in artificial intelligence algorithms with the goal of helping businesses use AI without running the risk of discriminating against certain people. From a report: Rich Caruana, a senior researcher on the bias-detection tool at Microsoft, described it as a "dashboard" that engineers can apply to trained AI models. "Things like transparency, intelligibility, and explanation are new enough to the field that few of us have sufficient experience to know everything we should look for and all the ways that bias might lurk in our models," he told MIT Technology Review. Bias in algorithms is an issue increasingly coming to the fore. At the Re-Work Deep Learning Summit in Boston this week, Gabriele Fariello, a Harvard instructor in machine learning and chief information officer at the University of Rhode Island, said that there are "significant ... problems" in the AI field's treatment of ethics and bias today. "There are real decisions being made in health care, in the judicial system, and elsewhere that affect your life directly," he said.

Mystery donor pledges $1 million to The GNOME Foundation

Despite being the default desktop environment for the two most important Linux distributions in the world -- Fedora and Ubuntu -- GNOME is not a money-making project. Actually, it is run by a non-profit called The GNOME Foundation that relies heavily on donations from both organizations and individuals. That's what makes GNOME so extraordinary -- the high quality desktop environment and apps are largely a labor of love. Today, The GNOME Foundation makes a shocking revelation -- a mystery donor has pledged $1 million dollars! We don't know who is promising the money -- it could be a rich man… [Continue Reading]
