He writes that the phone had the things he wanted most, and while browsing doesn't need a keyboard, writing book chapters and blog posts is painful on a phone screen – hence the painstaking effort to hack the laptop into a keyboard for the phone.“I use the phone for multiple interfaces, yes VNC, but more often using my laptop’s keyboard to interface to the phone’s existing apps, Termux (to SSH into my laptop), Chrome, Gmail, Whatsapp, etc.”Sorry to say, part A is always going to be painful – actually starting the laptop blind – and with a tiny screen area working he could remember how to get to the Linux desktop and a terminal screen.“By a huge stroke of luck I had the extra good fortune to have two text lines worth of working pixels at the top of the screen. Well I say working, they didn’t automatically update, I had to sort of twist the screen with my hands and at some point they’d decide to update.” To present the laptop's login interface via the phone, he had to install an OpenSSH client (also a blind install), and here's an important lesson for everyone: “always setup an SSH daemon with a strong password on a new laptop”.

For “normal” operations, though, Buckley-Houston wanted to get the laptop's keyboard working as a Bluetooth keyboard to the phone.By now, though, he's got a screen – so it was just a matter of testing various packages to see which worked best, and settling on one called Hidclient.The Register won't be trying this ourselves any time soon, but we're sure some of our readers will want to top this experience. We're always listening. Security startup MedSec and the financial house backing the biz have published new allegations of security flaws in pacemakers and defibrillators built by St Jude Medical – and again look set to profit from the disclosures in an unorthodox way.In four swish videos, the MedSec team claims it exploited a debugging backdoor in the St Jude-built Merlin@home control unit so it could send commands wirelessly to a patient's defibrillator. The team were able to hijack the the control unit after reverse-engineering its software, written in Java, and hooking a laptop to the unit via Ethernet.MedSec claims it could do away with the Merlin@home all together, and wirelessly send orders to people's devices in their chests from software-defined radio kit, after working out St Jude's protocols.Using the compromised terminal, the team says it managed to make the defibrillator vibrate constantly, turn off its heart monitoring software, or get it to administer a mild electric shock, which the actor narrating the video describes as "painful, and can be detrimental to a patient's health if used in an unprescribed manner."MedSec's CEO Justine Bone explained to The Register that the team had used a hacked MedSec device because it was the easiest route to show deficiencies in the device. By using old debugged developer code left on the device by the original designers, they were able to take control of it.

"We believe that this could be done from any wireless attack platform once someone had written out all protocols," she said. "It's going to be very hard to fix; you'd have to rewrite the RF communication protocols."Some of the attacks, particularly if used in conjunction with each other, could put lives at risk. But she acknowledged that in tests so far the maximum range of the defibrillator was limited to seven feet, so an attacker would have to be up close and personal.Bone also said that the MedSec team hadn't contacted St Jude Medical about the flaws before releasing the videos, and had instead gone to the Food and Drug Administration and the Department of Homeland Security. Bone said this was because St Jude doesn't have a good record of sorting out flaws like this.St Jude confirmed to The Register that MedSec hadn't passed on any details about the flaws, and made the following statement:

"Muddy Waters and MedSec have once again made public unverified videos that purport to raise safety issues about the cybersecurity of St Jude Medical devices. This behavior continues to circumvent all forms of responsible disclosure related to cybersecurity and patient safety and continues to demonstrate total disregard for patients, physicians and the regulatory agencies who govern this industry."The company is also setting up a Cybersecurity Medical Advisory Board to give it tips on how to build more secure products. However, it appears as though it's mostly staffed by doctors, who aren't the best for finding sloppy software holes.The whole sorry saga started in August when MedSec found what it claims were flaws in St Jude's devices. Rather than go to the manufacturer and sort these out, the firm partnered with financial house Muddy Waters and shorted the stock before going public with the news.The security firm now gets a payout based on how far St Jude's stock price falls – the more the better. St Jude and others have disputed the claims, and St Jude is now suing those involved in the disclosures. People who have St Jude devices implanted have been left panicked and confused by the whole matter.

In the meantime, many in the security community are worried that this kind of disclosure is just going to increase fear, uncertainty, and doubt in an industry sector already bedeviled with it. If short selling becomes the norm, then headlines rather than fixes will become the goal, and it's difficult to see how that benefits end users. HP Inc has disclosed pricing for HP Workspace, the Windows app-streaming service that allows its new Elite x3 business phone to fully replace a PC.Although Universal apps on Windows 10 mobile apps can adapt to run fullscreen with a keyboard and mouse, Workspace is needed to run legacy Win32 apps, which don’t run natively on ARM devices such as the x3. Workspace streams the apps to the Elite x3 at 15fps, sufficient for most business applications.The per-user monthly pricing is $79 and $40, depending on how much Win32 you need. Both packages give you a dedicated two-core vCPU. $79 buys you 8GB of virtual machine RAM and 80 hours per month, and unlimited apps. The more basic “Essential" tier aimed at “mostly mobile” workers buys you a 4GB RAM virtual machine and 40 hours of app streaming a month, limited to up to 10 apps.This isn’t cheap, but as Windows watcher Steve Litchfield points out, it’s cheaper than paying an in-house IT team to sit around all day, setting fire to the bins.And you can blame Microsoft for the pricing. VDI (virtual desktop infrastructure) as a service can be found cheaper via AWS, but Microsoft still sets a floor price.

Endet diese Herstellergarantie aber schon vor der zweijährigen Gewährleistungspflicht des Händlers, sollte man darauf achten, dass der Extraschutz direkt ab dem Kauf greift. Sonst muss man Reparaturen unter Umständen selbst zahlen, trotz zusätzlicher Garantie.Viele Zusatzgarantien kosten einmalig und laufen dann nach dem Schutzzeitraum von selbst aus. Einige Versicherungen verlängern sich aber automatisch von Jahr zu Jahr. Gerade bei Policen, welche nur den Zeitwert erstatten, wenn das Gerät kaputt geht, kann das zum Problem werden. Denn das verliert über die Jahre an Wert, so dass man am Ende bei Defekten oder Totalschäden kaum mehr etwas bekommt. Sittig: Das muss man auf dem Schirm haben, damit es kein Verlustgeschäft wird.Las Vegas (dpa/tmn) - Frische Hardware für Spieler, die häufiger unterwegs sind. Auf der Elektronikmesse CES in Las Vegas zeigen mit Gigabyte, MSI und Lenovo drei Branchengrößen neue Notebooks für Spieler.Gigabytes P57W richtet sich mit 17,3 Zoll Bildschirmgröße an Spieler, denen Handlichkeit nicht so wichtig ist. Im Inneren stecken Intels Skylake-Prozessoren und Nvidias Geforce GTX 970M. Die Tastatur soll auch Mehrfacheingaben durch gleichzeitige Tastendrücker zuverlässig erkennen. Das P57W ist ab sofort ab rund 1300 Euro verfügbar.

Deutlich kleiner ist MSIs GS40 Phantom mit 14 Zoll Bildschirmdiagonale. Auch hier sind Intels Skylake-Prozesoren verbaut, die Spielegrafik wird von Nvidias Geforce GTX 970M berechnet. Für ein Spieler-Notebook ist der GS40 Phantom mit 1,7 Kilogramm Gewicht recht leicht. Im ebenfalls vorgestellten GTS72S Tobii steckt die gleichnamige Augen-Tracking-Technik, die ein leichteres Steuern von Spielen und Programmen ermöglichen soll. Der Computer kann so ermitteln, auf welchen Teil des Bildschirms ein Spieler gerade schaut. Das GT70 Stealth-Modell mit 17 Zoll Bildschirmgröße hat eine neue Display-Option erhalten. Im GT72 Stealth Pro kann nun auf Wunsch ein 4K-Display (3840 zu 2160 Pixel) eingebaut werden. Alle drei Geräte sind noch im Laufe des Januars verfügbar.Lenovo zeigt mit dem Ideapad Y900 ein Gerät, das mit klassischen Laptops nur noch wenig gemein hat. In dem 4,5 Kilogramm schweren Notebook (17 Zoll Bildschirmgröße) stecken auf Knopfdruck übertaktbare Prozessoren, bis zu 64 Gigabyte Arbeitsspeicher und Grafikchips bis hoch zur GTX 980M von Nvidia. Die Tastatur verfügt über mechanische Schalter für jede Taste, was viele Spieler wegen höherer Präzision schätzen. Vier frei belegbare Makrotasten am linken Tastaturrand sind für häufige Aktionen programmierbar. In den USA soll das Ideapad Y900 ab Juni für rund 2000 US-Dollar (rund 1860 Euro) aufwärts verfügbar sein. Einen Termin für Deutschland nannte Lenovo noch nicht.

München/Berlin (dpa) - Der Einkauf im Netz wird bei den Kunden in Deutschland immer beliebter. Nach einem guten Weihnachtsgeschäft erwartet der Bundesverband Onlinehandel (BVOH) auch für das laufende Jahr ein Umsatzwachstum im niedrigen zweistelligen Prozentbereich.Mittlerweile würden auch immer mehr Produkte des täglichen Bedarfs übers Netz gekauft, sagte Verbandspräsident Oliver Prothmann der Deutschen Presse-Agentur. Es ist keine Besonderheit mehr, Waren vom Klopapier über die neue Zahnbürste bis hin zu Lebensmitteln online einzukaufen.Das beste Weihnachtsgeschäft seiner Geschichte erlebte etwa der Onlinehändler Otto, wie eine Unternehmenssprecherin sagte. Dabei standen Elektronik-Produkte wie Notebooks, LED-Fernseher und Smartphones auf der Hitliste der beliebtesten Geschenke ganz oben, aber auch Hausgeräte wie Waschmaschinen, Geschirrspüler und Kaffeevollautomaten. Angesichts von Umtausch und Gutschein-Einlösungen dürften sich die Ausläufer des Weihnachtsgeschäfts noch bis Ende Januar hinziehen.Ins laufende Jahr blickt das Unternehmen optimistisch: Wir gehen mit ausgesprochen positiven Erwartungen ins neue Jahr und wollen spürbar weiter wachsen, so die Sprecherin. Größtes Wachstumssegment für den Onlinehändler seien dabei Möbel - von Schränken über Betten bis hin zu Sofas.

Auch der Versandriese Amazon sprach von einem erfolgreichen Weihnachtsgeschäft. Genaue Umsatzzahlen nannte die deutsche Niederlassung des US-Handelsriesen aber nicht. Rekord-Verkaufstag für Weihnachtsgeschenke bei Amazon.de sei der 14. Dezember gewesen, an dem alleine mehr als 5,4 Millionen Produkte verkauft worden seien und damit so viele wie nie zuvor in der Unternehmensgeschichte.Bei der logistischen Abwicklung des Weihnachtsgeschäfts dürfte mancher Internethändler auch von der milden, schnee- und eisfreien Witterung im Dezember profitiert haben. Wer allerdings wie Zalando auf Mode spezialisiert ist, musste wiederum umsteuern, weil die tendenziell auch höherpreisige Winterkleidung in den Wochen vor dem Fest wetterbedingt wenig gefragt war.Auch der Handelsverband Deutschland hatte zuletzt über einen schleppenden Absatz von Wintermode berichtet. Dies mache aber dem stationären Handel mit seinen begrenzten Lagerkapazitäten üblicherweise noch stärker zu schaffen, weil er früh mit Rabatten beginne, um schon einmal Platz für die Frühjahrsmode zu schaffen, hieß es in der Branche. Wenn dann ein Kälteeinbruch kommt, hätten viele Geschäfte warme Kleidung nicht mehr parat - hier könnten Internet-Händler flexibler reagieren.Berlin (dpa/tmn) - Das Smartphone fordert alle paar Stunden die Steckdose, das Notebook hält ohne Netzteil nur noch wenige Minuten durch. Also höchste Zeit für neue Akkus. Doch Original-Ersatz ist teuer.

Nachbauten gibt es im Internet für viel weniger Geld: Kostet mancher Smartphone-Akku beim Hersteller um die 30 Euro, locken baugleiche, vermeintliche Schnäppchen-Batterien mit weniger als der Hälfte des Preises. Kann man da bedenkenlos zugreifen?Zumindest im Neuzustand können manche Ersatz-Akkus es in Sachen Laufzeit durchaus mit Original-Batterien aufnehmen, wie das c't-Magazin bei einem Test diverser Smartphone-Akkus ermittelt hat. Einige Nachbau-Akkus hielten genauso lange durch wie das Original, und einige sogar länger - etwa beim Samsung Galaxy S3 oder Google Nexus 4. Wir haben festgestellt, dass Nachbau-Akkus in der Regel schneller altern als die Originale, schränkt c't-Redakteur Christian Wölbert aber ein. Sie halten nicht so lange durch.Während die Original-Akkus im Test nach eineinhalb Jahren typischer Nutzung meist noch mindestens 80 Prozent ihrer ursprünglichen Leistung boten, lag die Kapazität der Konkurrenz-Produkte nach dieser Zeit meist deutlich darunter. Für Nutzer, die damit leben können, dass der Akku etwas schneller altert, seien die Nachbauten aber eine günstige Alternative, meint Wölbert.

Auch Jürgen Ripperger vom Elektrotechnik-Verband VDE rät nicht generell von Nachbau-Akkus ab. Wenn der Gerätehersteller die Nachbauten freigegeben hat, dann kann man zugreifen. Setzt man aber einen nicht freigegebenen Energiespeicher in Kamera oder Handy ein, erlösche die Produkthaftung des Geräteherstellers.Die Gefahr, dass Ersatz-Akkus explodieren, ist zudem gering, schreibt die c't: Jährlich würden Milliarden Akkus verkauft, bekannt seien aber weniger als zehn Fälle explodierender Akkus. Zudem habe es sich dabei teils auch um Original-Akkus gehandelt.Doch was ist eigentlich ein guter Nachbau-Akku und was ein schlechter? Das lässt sich pauschal nicht sagen, erklärt Wölbert. Die Qualität schwankt sehr stark. Denn während die Akkus einer Charge gute Leistung liefern, kann dies bei der nächsten Charge schon anders aussehen. Also ist ausprobieren angesagt.Wer einen Nachbau-Akku im Netz bestellt, sollte darauf achten, dass der Händler in Deutschland oder zumindest in der EU sitzt. Denn dann hat man die gesetzlich vorgeschriebenen zwei Jahre Gewährleistung auf den Akku, erklärt Jürgen Ripperger.Aber auch beim Kauf von Original-Akkus ist Vorsicht geboten: Viele vermeintliche Originale, die im Netz zu einem Bruchteil des Original-Preises angeboten werden, sind offenbar gefälscht. Das zeigte jüngst auch ein c't-Testkauf von zwölf als original gekennzeichnete Smartphone-Akkus bei einem großen Versandhändler. Das Ergebnis: Alle zwölf Akkus waren Fälschungen.

Selon Ubergizmo, il n’y a pas encore de news concernant le nom que Samsung va donner à son nouveau système d’ exploitation. Cependant, le site révèle que l’OS sera open source. L’ordre du jour de la conférence fournit cette information : « Samsung va annoncer son nouveau système d’exploitation en temps réel (RTOS) open source dédié à l’IdO, qui dispose d’un large éventail de fonctionnalités tout en conservant une empreinte légère et efficace ».Il y a eu récemment beaucoup de nouveaux développements liés aux plates-formes pour l’Internet des Objets. ARM a récemment annoncé son module de M2.COM – fabriqué en consortium avec d’autres entreprises – qui va embarquer l’OS d’ARM. Google a également annoncé son intention de se faire une place sur le marché dans un effort de promouvoir son travail avec les plates-formes Weave et Brillo. Enfin, un autre acteur, Orange, a déclaré sa flamme pour l’IdO avec son réseau LoRa.C’est donc tout ce que nous avons à ce jour, car il est peu probable que Samsung publie de plus amples informations sur ce nouveau système avant la Samsung Developer Conference qui aura lieu dans moins d’un mois.

Après avoir créé une pléthore d’appareils connectés SmartThings, et fournissant même des conseils aux développeurs afin qu’ils puissent construire des dispositifs intelligents, ce nouveau système d’exploitation de Samsung devrait aider à stimuler le marché.Microsoft va déployer cet été sa mise à jour « Anniversary Update » pour Windows 10, et entre autres choses, celle-ci va inclure un centre de notifications mis à jour, pour les notifications et les paramètres. L’une des nouvelles fonctionnalités les plus cool ? Vous serez en mesure de voir et répondre aux notifications de votre smartphone à partir de Windows 10. Et, cela est vrai si vous utilisez un smartphone sous Windows Phone ou sous Android.La société a révélé le projet et les détails lors de la Build 2016, en montrant comment le système fonctionne au cours de sa conférence.Néanmoins, il y a un hic : vous devez installer l’application Microsoft Cortana sur votre appareil Android si vous souhaitez synchroniser vos notifications — celle-ci est actuellement disponible uniquement aux États-Unis. Mais une fois que vous faites cela, vous serez en mesure de voir les SMS, les appels, ou d’autres notifications manquées sur votre smartphone. Vous voulez répondre à un message ? Vous devriez être en mesure de le faire depuis votre PC Windows, sans déverrouiller votre smartphone Android.

Si vous avez Windows 10 sur votre téléphone, il va également disposer du nouveau centre de notifications, et vos notifications seront synchronisées à travers les dispositifs, de sorte que vous pouvez les renvoyer sur un seul appareil et les faire disparaître sur l’ensemble de vos dispositifs. Le but est de vous permettre de rejeter de la même façon les notifications sur votre smartphone Android, mais encore une fois, cela ne fonctionne que si vous avez l’application Cortana installée sur votre smartphone.Alors que Microsoft propose également une application Cortana pour iOS, la firme n’a pas autant accès aux entrailles du système d’exploitation que la version Android, donc elle ne peut pas synchroniser vos notifications sur un ordinateur sous Windows 10 de la même manière.Les autres nouvelles fonctionnalités de la mise à jour de Windows 10 Anniversary Update vont être un support amélioré pour la saisie au stylet, une fonctionnalité de sécurité biométrique avec Windows Hello dans le navigateur Web Edge pour se connecter à des sites Web à l’aide d’une empreinte digitale de l’iris ou la reconnaissance faciale, et l’inclusion d’un sous-système Ubuntu Linux qui permet d’exécuter un shell Bash dans Windows.Après les grandes projections de l’an dernier sur Windows 10 et le casque HoloLens, la Microsoft Build de cette année était plus incrémentale. Bien que Microsoft n’ait pas communiqué ou annoncé une nouvelle version de Windows lors de l’événement, ou même un tout nouveau matériel, la firme nous a permis de jeter un coup d’œil à ce qui va venir dans la mise à jour dite « Anniversary Update » de Windows 10, qui doit sortir cet été.

Rappelez-vous, Windows 10 est la dernière version numérotée de Windows. Autrement dit, attendez-vous à voir de plus petites, mais plus régulières mises à jour. Plus de 270 millions de personnes sont passées sur Windows 10, a annoncé Terry Myerson, à la tête de Windows, lors de la keynote d’ouverture de la Build. Mais, même l’Anniversary Update va manquer de fonctionnalités flambant neuf. À contrario, le géant de Redmond va pousser un peu plus loin des fonctionnalités existantes, comme son assistant numérique, Cortana.Une grande partie de ce qui va venir pour Windows est surtout intéressante pour les développeurs. Par exemple, de nouveaux outils vont permettre de facilement porter les applications conçues pour les versions précédentes de Windows vers des applications dites « modernes », dédiées à Windows 10 et accessibles depuis le Windows Store. Et, le système d’exploitation offrira un support au Bash shell Linux, permettant d’exécuter davantage d’applications. Je dois souligner que Windows 10 Anniversary Update ne concerne pas seulement les PC, mais aussi les smartphones, les tablettes, la Xbox, ou encore les dispositifs de l’Internet des Objets ainsi que le HoloLens.

Non seulement Cortana va devenir plus proactif, ce qui suggère plus de choses comme où déjeuner si vous êtes dans une ville inconnue (puisque vous lui avez indiqué vos préférences de cuisine), mais l’assistant vocal va apparaître dans plusieurs endroits du système, telles que l’écran de verrouillage ou encore au sein de Skype lors d’une conversation avec un bot. Si l’intégration de Cortana sur l’écran de verrouillage est un sujet délicat concernant la vie privée, les représentants de Microsoft ont mentionné que vous pourrez filtrer ce qui s’affiche à l’écran.Une intrigante fonctionnalité de Cortana qui n’a pas été beaucoup discutée lors de la keynote est le contrôle du système par Cortana. « Hey Cortana arrête le PC ! » ne fonctionne pas maintenant, mais une vidéo présentée à la Build suggère qu’une telle caractéristique sera disponible dans l’Anniversary Update. Je me demande si cela signifie aussi que Cortana sera en mesure de modifier les paramètres système, comme « Désactiver le Wi-Fi » ou « Regarde les mises à jour ».Cortana se retrouve désormais intégré au sein de multiples applications tierces, afin d’obtenir des réponses sur certaines questions, tout en effectuant des actions. Si vous l’avez utilisé, vous savez que l’assistant peut facilement obtenir des informations sur TripAdvisor ou encore la météo, mais la société a lancé une nouvelle section « Mieux avec Cortana » dans la boutique d’applications Windows, qui liste près de 1 000 applications qui intègrent maintenant Cortana. Alors soyons fou, « Cortana, va me chercher une voiture Uber ! ».

You may not need HP Workspace at all to make use of the Elite x3, it runs some UWP surprisingly well. It’s just that many applications are missing in UWA format – as we found when we tried to use Continuum for real work.HP has built a comprehensive hardware and software package around the promise of Windows 10 – including a laptop dock (basically a shell of a laptop with a 12.5 inch HD display – pdf), and a desk dock. Orders can be placed with HP for the phone but Microsoft has yet to fulfil its side of the bargain, as Continuum remains resolutely single window for now.Comment Red Hat is the biggest – and one of the oldest – companies in the Linux world, but despite the difficulty of accurately measuring Linux usage figures, Ubuntu and its relatives seem to be the most popular Linux distributions. Red Hat isn’t sitting idle, though. Despite its focus on enterprise software, including virtualisation, storage and Java tools, it’s still aggressively developing its family of distros: RHEL, CentOS and Fedora.Fedora is the freebie community-supported version, with a short six-month release cycle, but it’s still important. Although RHEL is the flagship, it’s built from components developed and tested in Fedora. According to Fedora Project Lead Matthew Miller told this year’s Flock to Fedora conference this summer its future looks bright.After the major "Fedora.next" re-focus in early 2014, Fedora's numbers are up. Both new downloads and updates to installed systems are rising. External involvement – that is, from non-Red Hat staffers – is sharply up: two-thirds of Fedora's contributors are from outside the company these days. And yes, that's counting 'Hatters using non-company email addresses.

It's getting better as a distro, too, benefitting from the improving fit-and-finish of Linux and its manifold supporting components: desktops, applications and their less-obvious underpinnings. Fedora 24 is significantly more usable than it was five or six releases ago. Rather than just being the testbed for future RHEL releases, the project now has wider aspirations – Miller identified the project's primary target as developers.I must confess, I lean more towards Ubuntu, only periodically dipping a toe into the waters of the RPM world. So when looking at Fedora, it’s sometimes irresistible to draw comparisons with the more orangey-purple side of the fence.And these days it's a family rather than a single distro. The old structure of Fedora Core plus additional rings of functionality has been discarded in favour of multiple "flavours", "spins" and "labs"."Flavours" are akin to Ubuntu's editions: as well as the standard GNOME 3 desktop, there's Fedora Server plus the ultra-minimal Fedora Cloud. Fedora's "spins" resemble Ubuntu's remixes, offering KDE, Xfce, LXDE, Maté-Compiz and Cinnamon. An interesting addition is SOAS, a live USB drive with the One Laptop Per Child's Sugar environment.Fedora's Labs are a more versatile equivalent to Ubuntu's handful of special-purpose editions. Labs are pre-assembled bundles of functionally related software, which can be installed as standalone distros or added into existing installations. Finally, COPRs are directly analogous to Ubuntu's PPAs: ad-hoc supplementary repositories to facilitate adding new software that isn't part of the main distro.The overall structure of the software is changing, too. Platform Architect Langdon White’s talk at the conference introduced the Modularity initiative, an attempt to restructure the entire project down into functional modules which can be installed and updated independently, in different ways – for instance as classic RPM packages or container images.Atomic Workstation represents another possible future direction – a smartphone-like OS, with a read-only root partition, installed and updated via OSTree, with all applications in Docker containers.

As of the version 25, standard Fedora will support the Raspberry Pi 2 and 3. Fedora is an all-FOSS distro, with no proprietary drivers, firmware or plugins, so it doesn't support the Pi 3's Wi-Fi and Bluetooth, as these require binary blobs. (We're told there are efforts underway to help people install closed-source components, such as Chrome, by the way.)There are still downsides to Fedora relative to Ubuntu. There are no long-term support releases, as that's the role of the technologically much more conservative CentOS. Ubuntu's more pragmatic attitude to including proprietary binaries means more hardware works out of the box, and installing the "restricted extras" package enables Flash, MP3 and so on in one easy operation. But the Red Hat family has come a long way. The 7mm 2.5-inch drives are for standard laptop drive bays, while the 15mm ones are for desktops. We're led to believe that these thicker, higher-capacity 2.5‑inch drives will feature in upcoming external storage products.Seagate says all disk drives in the BarraCuda family have Multi-Tier Caching Technology (MTC) to speed data reads and writes. This uses a hierarchy of NAND Flash, DRAM and media cache technologies to optimise the data flow.

Apparently the drives have new firmware that checks how data accesses are operating and spins the platters down when it can, to reduce power consumption without affecting performance. This might seem of not that much consequence to consumers and small businesses, but it matters more to larger businesses with bigger electricity bills.The 2.5‑inch BarraCudas spin at 5,400rpm, have a 6Gbit/s SATA interface, transfer data at up to 140MB/sec and come with a 2‑year limited warranty.

The 7mm thick 2.5‑inch drive has two platters, and the 15mm model has five 1TB platters.The 3.5-inch BarraCudas and BarraCuda Pros are faster, spinning at 7,200rpm, and have a longer, 5‑year warranty. Seagate claims the BarraCuda Pro is the fastest 10TB desktop drive available.The 500GB – 4TB BarraCudas have 1, 2 or 3 1TB platters, a 64MB cache and 55TB/year workload rate limit. The highest sustained transfer rate is 210MB/sec (180MB/sec for the 4TB model). Get a PDF data sheet here.BarraCuda Pros have either 6 platters (6TB and 8TB) or 7 (10TB). Their maximum sustained transfer rate from the data sheet [PDF] is 210MB/sec, while the workload rate limit is 300TB/year.The FireCuda 2.5-inch accelerated drives can be viewed as 7mm BarraCudas with added 8GB cache. Their sustained transfer rate is the same as the BarraCuda; 140MB/sec, though. Seagate isn't revealing the spin speed in the data sheet [PDF], but we figure it's 5,400rpm again.

Sticking these FireCudas in a 3.5‑inch case gets you a 7,200rpm spin speed and a 210MB/sec sustained transfer rate.FireCudas have a 5‑year warranty and, like the BarraCudas, use MTC to speed their operation. They are not given a workload rate limit by Seagate.FireCuda drives operate in the performance gap between basic disk drives and SSDs. We can't expect them to get significantly faster, particularly as the per‑GB cost of flash is dropping with 3D TLC NAND. Caringo has updated its Swarm object storage software and will flog the code on appliances based on Dell PowerEdge servers.Deployments of Caringo's object storage is used for applications such as bulk storage, analytics, archiving, backup, cloud storage and content distribution. The software provides NFS, SMB, S3, HDFS and Rest APIs for native object storage access methods to data.Swarm 9 is the latest release of Caringo's software. It has an NFS protocol converter and the OEM hardware platform in addition to its availability in software-only form. The software features:Data is managed through creation to expiration via administrator-defined policies called Lifepoints, which are stored as metadata that automatically manages the number of replicas, erasure-coding scheme, and deletion.

There can be metadata annotations, made without modifying the reference object, and these are searchable through the SCSP API.The company says Swarm Servers are a fully-supported hardware and software system starting at 288TB and scaling linearly in 96TB increments (just add another S-Series server) to hundreds of petabytes of capacity with a pay-as-you-grow pricing scheme.The system includes M-Series Management Servers and S-Series Storage Servers. The M-Series is a 1U, rack-mountable appliance with a Dell PowerEdge R630 inside it. It has a Xeon E5-2695v4 processor with 18 cores, 128GB DDR4 DRAM, 8 x 1TB, 7,200rpm SAS disk drives, 2 x 10GbitE data access ports and a 1GbitE management port. VMware's ESXi is booted off an internal SD module.The management software is Swarm VMware APP, with a vCenter Server Appliance and ESXi 6.0U2. There is a scale-out, stateless NFS protocol converter for high performance and high availability.The 2U, rackmount, S-3000 Storage Servers use a PowerEdge R730xd platform, with CPU, memory and network resources, plus 96TB capacity. The CPU resource is 2 x Xeon E5-2640v4 10 core processors; 20 cores total, plus 128GB DDR4 DRAM and 12 x 8TB, 7,200rpm SAS disk drives. There are 2 ports of 10GbitE (Intel x540) for data access and a 1GbitE management port.
