Manjaro 18.1: Goes Arch One Better



Manjaro Linux 18.1, released on Sept. 12, is one of the most complete Linux OSes you will find. It is a powerhouse distro that offers a better Arch Linux computing platform, and it is the de facto standard for comparing Arch family options. After six months of development, the latest series is a fast, user-friendly, desktop-oriented operating system based on Arch Linux — but its independent nature makes this distro a hallmark of out-of-the-box computing. Arch Linux itself is renowned for being exceptionally fast, powerful and lightweight.

Which size Samsung Galaxy Watch should you buy?

Samsung has a wide-ranging set of wearables that can be tough to narrow down. We're here to help you pick the right one for your needs..

Galaxy Watch 42mm

Fits most wrists

$250 at Amazon

Pros

  • Fits a wide range of wrist sizes comfortably
  • Comes in both black and rose gold colors

Cons

  • Battery life isn't great, especially with an always-on watch face

Samsung managed to get every possible smartwatch feature into a relatively compact package with the 42mm Galaxy Watch. It does everything the larger version does, including optional LTE, but comes up short on battery life if you push it hard.

Galaxy Watch 46mm

Battery champ

$270 at Amazon

Pros

  • True multi-day battery life no matter what
  • A little more display to look at

Cons

  • Only comes in one color
  • Too large for many wrists

The 46mm Galaxy Watch is very much a successor to the Gear S3 Frontier in that it can do everything you want, for multiple days, without charging. The massive battery and same basic specs as the smaller watch give it impressive longevity no matter how you use it.

Samsung has a Galaxy Watch marketing message of „same watch, two sizes“ and that's actually true. There are just a couple of subtle differences to explore here.

What's the difference?

We're going to focus on the few differences below, but the important thing to do know is there are only a few differences — most of the experience is the same for either one. Both watches have the same processor, memory, storage, software, and capabilities. They can both track daily activity and fitness with GPS, have heart rate monitoring and have optional LTE connections.

Galaxy Watch 42mm Galaxy Watch 46mm
Display 1.2-inch 1.3-inch
Battery 270mAh 472mAh
Dimensions 41.9 x 45.7 x 12.7mm 46 x 49 x 13mm
Strap 20mm 22mm
Colors Black
Rose gold
Silver
LTE Optional Optional

Even the areas where they're slightly different are merely marginal changes. The displays are the same quality and resolution (360×360), with just a 0.1-inch size difference, and have the same rotating bezel for interaction. Both watches have removable straps that are compatible with any standard watch band, the only difference is the size: 20 vs. 22mm.

The price difference is negligible. The larger version is just $20 more, so unless every dollar matters, you should decide based on the other factors instead.

How big of a watch can you handle?

Choosing which size of Galaxy Watch is right for you has to start with knowing how big of a watch you — or more importantly, your wrist — can handle. The 46mm Galaxy Watch is big, particularly if you aren't used to wearing large mechanical watches. This is a pretty big case size, but it's also combined with a 13mm thickness that makes it tough to fit on smaller wrists. If at all possible, go try on the different sizes in a store before buying — you may be surprised by just how large the 46mm is.

If you're worried at all about size, you'll need to just go with the 42mm. It doesn't seem like that 4mm would make a big difference, but it really does. It's still a bit large for people with small wrists, but it's doable — whereas the 46mm can be downright too large for some people to wear. The 42mm also comes in two different color choices, black and rose gold, which kind of acknowledges that women with smaller wrists would prefer the 42mm model anyway.

Battery life matters

If size isn't a concern for you, then the battery life is probably important. This one isn't really a contest: the Galaxy Watch 46mm has a much larger battery and notably longer battery life as a result. You can get multiple days of battery life out of the 42mm model, but you have to be careful and change some settings to accomplish it — the 46mm can give you multi-day battery life no matter what.

If you aren't interested in tracking your sleep and will be charging your watch every night as a result, then this really isn't an issue — even the 42mm can last a full day with every feature turned on. But tracking sleep adds extra stress on the battery and cuts down on charging time, so you'll have to turn off the always-on watch face in order to make it multiple days. The 46mm can do multiple days, including sleep tracking and an always-on watch face.

Fits all wrists

Best choice based on compatibility.

$250 at Amazon $330 at Best Buy

The 42mm Galaxy Watch does everything the 46mm does, except it does it for a shorter time between charges. It'll fit men's and women's wrists, and comes in both black and rose gold for more style options. It's the best all-around choice.

Battery champ

Multi-day battery life.

$270 at Amazon $330 at Best Buy

The 46mm Galaxy Watch is all about one thing: battery life. You won't have to think about recharging every day, no matter what. Unfortunately, it's too big for many to wear comfortably and with every style of clothing, and only comes in one color.

VirnetX's $503 Million Patent Win Over Apple Vacated on Appeal in Mixed Result



The result is a mixed one for Apple at this point, with the appeals court finding only a partial reversal in affirming infringement by Apple on two counts and reversing on two other counts. The appeals court is sending the case back to district court to determine whether revised damages against Apple can be calculated or if a new damages trial will have to be held.

The case in question is just one of two involving Apple and VirnetX over communications security patents related to VPN, iMessage, and FaceTime. Apple is currently on the hook for $440 million in the other case, but appeals remain in progress.

Documenting Proper Git Usage

git emblem

Jonathan Corbet wrote a document for inclusion in the kernel tree, describing
best practices for merging and rebasing git-based kernel repositories. As he put
it, it represented workflows that were actually in current use, and it was a living
document that hopefully would be added to and corrected over time.

The inspiration for the document came from noticing how frequently Linus
Torvalds

was unhappy with how other people—typically subsystem maintainers—handled
their git trees.

It's interesting to note that before Linus wrote the git tool, branching and
merging was virtually unheard of in the Open Source world. In CVS, it was a
nightmare horror of leechcraft and broken magic. Other tools were not much better.
One of the primary motivations behind git—aside from blazing speed—was, in
fact, to make branching and merging trivial operations—and so they have become.

One of the offshoots of branching and merging, Jonathan wrote, was rebasing—altering the patch history of a local repository. The benefits of rebasing are
fantastic. They can make a repository history cleaner and clearer, which in turn
can make it easier to track down the patches that introduced a given bug. So
rebasing has a direct value to the development process.

On the other hand, used poorly, rebasing can make a big mess. For example, suppose
you rebase a repository that has already been merged with another, and then merge
them again—insane soul death.

So Jonathan explained some good rules of thumb. Never rebase a repository that's
already been shared. Never rebase patches that come from someone else's repository.
And in general, simply never rebase—unless there's a genuine reason.

Since rebasing changes the history of patches, it relies on a new „base“ version,
from which the later patches diverge. Jonathan recommended choosing a base version
that was generally thought to be more stable rather than less—a new version or a
release candidate, for example, rather than just an arbitrary patch during regular
development.

Jonathan also recommended, for any rebase, treating all the rebased patches as new
code, and testing them thoroughly, even if they had been tested already prior to
the rebase.

„If“, he said, „rebasing is limited to private trees, commits are based on a
well-known starting point, and they are well tested, the potential for trouble is
low.“

Moving on to merging, Jonathan pointed out that nearly 9% of all kernel commits
were merges. There were more than 1,000 merge requests in the 5.1 development cycle
alone.
