Akademy 2017 -- Day 1

LXer - Sun, 2017-07-23 20:57
During the first day at the Akademy, everything went according to plan and nearly everything was on time. Kudos to the organisers.The weather was balmy at the beginning of the day and, although Aleix Pol said it was not hotter than a hot day in Barcelona, many of the Scandinavian and Scottish attendees were visibly wilting under the sun. Fortunately for them, the venue is equipped with air-conditioning...

Web Workshops react.js -- Basic Demo with react.js

LXer - Sun, 2017-07-23 19:03
According to their authors React JS was built with a main objective: That the construction and maintenance of large applications with data that change over time, be as simple as possible .React JS is a Javascript library whose main focus is on user interface (view) management. React JS will automatically manage UI updates when it detects changes to the internal data that each component of the view will have. When the data changes, React JS updates only those parts that have changed , is almost magical and very good for application performance, does not need to map, or make changes throughout the DOM unnecessarily.

Qubes OS 3.2

TuxMachines - Sun, 2017-07-23 18:15

All in all, the Qubes OS team did an awesome job on integrating all this things so far. The security of the App VMs is not better than the security of the corresponding Template operating systems. However, if a App VM gets an issue, it does not affect the others. If you plan to do weird things, you can use a disposable VM where all changes gets discarded afterwards. It is very easy for anybody to create App VMs without network for example. And this is something I would like to use ever since I stumbled over Firejail which provides app-specific sandboxing.

In general, the documentation of Cubes OS is awesome. I learned a lot and I had to. Cubes OS is nothing to set-up by aunt Martha. You have to have deeper technical understanding to set-up the system. Afterwards, anyone is able to use it with a short introduction to the basic guidelines.

Of course, I found some usability issues and some bugs here or there. But overall, Cubes OS is a valid option for a security purist or a privacy-aware person.

When Qubes OS meets my personal requirements, it complicates things though. For example the file server/client architecture adds complexity you don't have to maintain within a personal computer.

Accessing USB devices, network printers and so forth is cumbersome as well.

You have to set your priorities.

Will I install it on my notebook or desktop and use it on a daily basis? My notebook would be cool since it is in potential harmful environments such as WiFi networks I don't control. On the other side, I do need USB flash drive access with good usability and need to connect to projectors.

My home server/computer runs 24/7 and could profit from Cubes OS since I got many different things running on this machine. I could separate those domains. Working in offline VMs with applications that don't need network is also a very nice thing to have. The USB flash drive thing is also a big thing here. Restricting to LAN access only would be fine. System crash resulting in an encrypted system that does not boot any more is a no go.

Well, I am not convinced yet. Probably I stick to Debian 9 or I do find the urge to come around the issues and find a Qubes OS setup which serves me well.

Tried Installing Mint, broke everything

Reddit - Sun, 2017-07-23 17:50

My laptop originally had Windows 10 installed. I dual booted it with Elementary OS and everything was working fine.

Recently I wanted to switch to Mint 18, I downloaded the ISO file and created my Bootable USB and booted up the Live Mode. The idea was that I'd use the partition manager to format the Elementary partition and install Mint there, however I ended up checking a box that said something about LVM or something, and that messed with my partitions and bootrecords.

Now I can't boot into eOS or Windows, and neither Windows boot repair, nor the equivalent 'nix program boot-repair could fix it. I really don't want to lose all the data on my laptop HDD, does anyone have any possible solutions?

Tl;Dr Broke Windows/eOS dual boot by not reading pop-ups in Mint installer, need help fixing bootrecords so I can get Atleast windows back.

Why polkit is needed?

Reddit - Sun, 2017-07-23 17:48

Simple question, what is the problem that polkit tried to solve? Why dbus method calls should go in a series of polkit policy checks before performing the required action? Why not just that upower checks the caller groups, if he/she belongs to "power" then it is okay, otherwise permission denied? Same goes for mount/umount/... on "plugdev" group for example.

Why retaining the Unix groups simple concept is not enough in the case dbus daemons/polkit world? What are the advantages of implementing something like polkit?

BTW: I do develop system bus daemons with desktop clients, and I do see polkit as an abuse.

Compatibility and Laptops

Reddit - Sun, 2017-07-23 17:43

Hi all, my name is Tom. Let's keep this short and sweet.

[TL:DR] How do I know which machines will run linux effectively and how do people normally purchase im regards to Linux installation?

I have no prior experience with Linux. I am looking to invest in a new laptop soon to use for work as I am an aspiring web design/developer. I have heard that Linux is particularly useful in this pursuit due to its ease of workflow and customisation possibilities as well as simply learning Linux seems to be a useful tool. To this point I am a "Windows Wamble" as I have only ever been told to use windows, its the industry-leading product, and it's simply the "go to" until you learn otherwise.

My question is simply... As Linux doesn't have amy "pre-installed" machines ie laptops, what is the most important thing to consider when looking for a laptop i want to install Linux on? As a secondary question... what is the normal system? Do people usually buy a windows machine and immediately convert it? I want to avoid paying out for a laptop only to find it is not compatible or optimal.

I am new to this community and pursuit so apologies if this was not an easy question in any way.

All the best,

Tom
