Raspberry Pi Linux OS Review

The arch-ports mailing list and #archlinux-ports IRC channel on Freenode will be used for further coordination. However, as there is still some interest in keeping i686 alive, we would like to encourage the community to make it happen with our guidance.

The Raspberry Pi line of mini computers — including the all-new Pi Zero W — are wonderful devices for what they are. Quite frankly, they have inspired many young people to learn about programming, while helping makers to create some really cool projects. With that said, the Pi computers are not the only System on a Chip solutions on the market.

If you have a PHP code base with some statsd calls amongst slow / data-intensive code to generate complex pages, there won’t be much difference. But I have conducted cpu profiling of high-performance Golang applications, both at Vimeo and raintank, and when statsd was used, the apps were often spending most of their time in UDP writes caused by statsd invocations. There are some statsd clients that buffer messages and send batches of data to statsd, reducing the UDP writes, which is a lot more efficient. This does come with some problems however, see the gotcha below. This is a common, and the original setting, for statsd instrumentation calls. Typically they were using a simple statsd client, where each statsd call corresponds to a UDP write. Other code running, and its performance. You can also use sampling to lower the volume.

The rest have a command to configure the driver run_command to the correct systemd binary for that distribution. Service enabled when the package is installed, so we only have to have one provision command to enable sshd for opensuse. All of these distributions except for opensuse have sshd.

Bytes_free) Graphite returns the sum of all bytes_free’s for all your servers, at each point in time. Graphite functions don’t exactly follow the rules of logic (by design). When you request something like sumSeries(diskspace. 2) Null handling in math functions. However, if only some – but not all – of the terms are null, they are counted as 0. If all of the servers have a null for a given timestamp, the result will be null as well for that time.

As a bonus, scripts like Composer work fine with the default configuration now. While this requires a more responsible configuration by the user it also eliminates some surprises. And after all this is the Arch way. With PHP 7 I am trying to move closer to upstream defaults and be less opinionated.

It is simple to use, extremely cost effective and, more than once, it has saved me from myself; making it easy to retrieve copies of files that I have inadvertently overwritten or otherwise done stupid things with1. I started using Tarsnap about three years ago and I have been nothing but impressed with it since. When I first posted about it, I included a simple wrapper script, which has held up pretty well over that time.

3 and the keyring package. While this was already possible in the past, it is now way easier to get started thanks to pacman 4. Once you have verified the finger prints of the five master keys you might want to actually configure pacman to verify packages.

Technologies like OpenStack and DC/OS, powered by Apache Mesos, are allowing them to replicate much of the functionality that was previously only available with proprietary, hosted solutions. Taking this one step further, several open source projects and organizations have begun full-scale open sourcing of their infrastructures, allowing other organizations to directly benefit from their Continuous Integration tooling and more. Today, following a rush to cloud, companies are now looking for open source tooling to build cloud-like environments in their own new data centers. Complete infrastructures have now become open source projects unto themselves, and operations engineers becoming more experienced open source contributors, alongside their developer colleagues.

If we had already connected to this server previously then the host key would already be in our known_hosts file and we wouldn’t have to respond yes or no regardless. Now if we wanted to skip StrictHostKeyChecking all together we could use the -o switch as shown in the below examples which would automatically add the far end servers RSA key fingerprint or “host key” to our known_hosts file.

It also wouldn’t really be fitting to start this list without there being an entry for flash 🙂 So, here are some of the big updates for Mageia 6:. So this is the first time that there has been a Mageia 6 heading here, which is a nice addition, to say the least.

The kernel fixed them up. The MTRRs were inconsistent, but they aren’t anymore. While it isn’t absolutely proper, it is very common. In English, using “had” as past or past perfect tense commonly implies that the condition no longer exists. Everything is fine now.

(February 16, 2017) Steve Longerbeam: i. (February 21, 2017) Eugeniy Paltsev: dmaengine: Add DW AXI DMAC driver. The block layer has also gained support for the Opal storage specification, providing a mechanism for the encryption of stored data.

There is a new type for the implementation of reference counters called refcount_t; its purpose is to facilitate defenses against reference-count overflows. (February 20, 2017) Yannick Fertre: STM32 LCD-TFT display controller. That is useful in its own right, but the real news is that it enables the merging of the long-awaited BFQ I/O scheduler.

February 22, 2017 The transition to the version-2 control-group API has been underway for a few years now. Alas, this feature would appear to be entirely undocumented in the kernel. (February 20, 2017) Patrick Vogelaar: add driver for cypress cy8cmbr3102. (February 20, 2017) Greg KH: Linux 4. The intermediate group could be hidden from administrators, but it would need to be there internally. (February 22, 2017) Memory management Anshuman Khandual: Enable parallel page migration. Txt for more information. This group can then be populated with a hierarchy of “thread groups” below it. When the control-group interface was reworked, two fundamental design decisions shaped the result in ways that are relevant to the CPU controller. Thread groups look like regular control groups, but with some significant differences: they can contain both threads and other thread groups, and a single process’s threads can be spread across multiple thread groups.

Some information can seemingly be found in RFC 7609 and this slide deck [PDF]. So, rather than putting T1 directly in the root group as shown above, it would be placed in a new group (call it “C”), and C would be located under the root. In this example, the “processes” P2 and P3 could, in fact, be threads belonging to the same process. Control groups would no longer be allowed to contain both processes and other groups; instead, control groups would be internal to the group hierarchy and processes would be placed only at the leaves. 11 release can be expected at the end of April. (February 20, 2017) Jozsef Kadlecsik: ipset 6. (February 16, 2017) sean. Wong: vfs/xfs/ext4: GETFSMAP support. That restriction exists because to do otherwise would be a violation of the “no internal processes” rule.

(February 16, 2017) David Daney: genirq/gpio: Add driver for ThunderX and OCTEON-TX SoCs. The new API also differs from the original in that it only allows entire processes to be placed within a group; if a process is multi-threaded, all of its threads must be in the same group.

The version-2 API make such configurations impossible, though, to the dismay of users who felt they had lost an important capability. When a threaded group would share the same parent group as a non-threaded group, the answer is to interpose another group. (February 22, 2017) Icenowy Zheng: [PATCH 4/8] drm/sun4i: add support for sun8i DE2 mixers and display engines. The use case he has in mind involves running a threaded workload directly out of the root group, resulting in a hierarchy looking something like this: The main reason for running the workload in the root group would appear to be performance; there is a small cost to putting processes lower in the hierarchy. (February 20, 2017) Darrick J. For non-thread-capable controllers, the thread groups would vanish and the processes contained therein would appear to be contained in the parent — the root group in this case.

Some controllers, though, can work well in a more flexible mode; the CPU controller is at the top of that list. It makes sense for processes to compete with control groups for the CPU, and it is often desirable to apply different CPU-usage policies to different threads within the same process. A separate “resource groups” mechanism was proposed almost one year ago, for example, but it brought little satisfaction and did not get far. Potential solutions to this problem have been under discussion for some time. The version-2 API make such configurations impossible, though, to the dismay of users who felt they had lost an important capability.

linux - Kernel panic involving an unknown_bootoption maybe ...

11 release can be expected at the end of April. 11 merge window will remain open through March 5, and the final 4. If the usual schedule holds, the 4. As usual, LWN will continue to watch the patch stream and summarize the rest of the merge window in the coming weeks.

Even without access to your bootloader it is possible to change your kernel parameters to enable debugging (if you have root access). However /proc/cmdline is not writable even as root, so this hack is accomplished by using a bind mount to mask the path. This can be accomplished by overwriting /proc/cmdline which stores the kernel parameters.

That restriction exists because to do otherwise would be a violation of the “no internal processes” rule. That would bring back all of the problems that this rule was created to avoid. For non-thread-capable controllers, the thread groups would vanish and the processes contained therein would appear to be contained in the parent — the root group in this case.

Assuming you’re not forcing your motherboard to use an invalid system clock (i. The Abit BP6 is notorious for this flaw, but it’s not unheard of on other boards (such as the Gigabyte BXD), and it’s possible on any board that uses APICs. AGP other than 66 MHz), this is strictly a physical design flaw in your motherboard.

There is a new type for the implementation of reference counters called refcount_t; its purpose is to facilitate defenses against reference-count overflows. A hierarchy using this feature might look like this: The thread groups (“T1” and “T2”) form their own hierarchy below B, which has been marked as a thread point. Most resource controllers work with the new interface, but there is a notable exception in the form of the CPU controller, which has been stalled as a result of disagreements over thread-level control. The purpose here is to better hide the internals of this structure so that they can be changed to use the new refcount_t type. (February 20, 2017) Karel Zak: util-linux v2. There are solid reasons for these decisions: for many controllers, it is difficult to define rational semantics when processes and groups are competing in the same parent group, and a number of resources (memory usage, for example) are not amenable to control at the thread level. That would be a welcome end to a project that has taken rather longer than anybody involved would have expected or wanted. (February 20, 2017) Yannick Fertre: STM32 LCD-TFT display controller.

This type should be used instead of atomic_t for reference counters; expect a set of conversions of existing atomic_t reference-counting usage over the next development cycle or two. Zijlstra would still like to apply full resource control to other groups that might, for example, contain a virtual machine running some sort of secondary workload.

So, rather than putting T1 directly in the root group as shown above, it would be placed in a new group (call it “C”), and C would be located under the root.

This is the blank or null pattern. The AWK program below: BEGIN { print “START” } { print } END { print “STOP” }. Two other important patterns are specified by the keywords “BEGIN” and “END”. The pattern specifies when the action is performed. That is, the pattern specifies a test that is performed with each line read as input. Like most UNIX utilities, AWK is line oriented. The default pattern is something that matches every line. If the condition is true, then the action is taken. As you might expect, these two words specify actions to be taken before any lines are read, and after the last line is read.

Command output to variable assignment and screen. I would like to continue to capture this output in a variable. Unix commands, linux commands, linux.

If you want exact match you can use $’string’. The minor differences are the treatment of escaped characters and new line character. Double quoted string in shell is almost identical to double quoted string in Perl and performs macro expansion of all variables in it.

The choice between hard limit (which no process is allowed to violate, and which may not be raised once it has been lowered) and soft limit (which causes processes to be signaled but not necessarily killed, and which may be raised) is made with these flags:. Inquire about or set the hard or soft limits on processes or set new limits.

If child process has already teminated, the wait() call returns immediately. Wait(): Blocks calling process until the child process terminates. If the calling process has multiple child processes, the function returns when one returns.

You can also specify the filenames on the command line. Normally you use standard input to provide AWK with information. This can be used if several files need to be parsed by AWK. If the above script was called “testfilter”, and if you executed it with testfilter file1 file2 file3.

All the text on successive lines up to the delimiter is saved away and made available to the command on standard input, or file descriptor n if it is specified. If the delimiter as specified on the initial line is quoted, then the here-doc-text is treated literally, otherwise the text is subjected to parameter expansion, command substitution, and arithmetic expansion (as described in the section on “Expansions )” If the operator is “

Note: If no distribution is specified as the value of the DISTRIBUTION and OSTEMPLATE variables in the Container configuration file or no configuration file for the given Linux version was found in the /etc/vz/conf/dists directory, the default file from this directory is used.

So, obviously, this article will not be exhaustive, but instead focus on a smaller set of some well-known options that may be interesting to readers. At my previous job, an inventory was done of about 40 different free-software password managers in different stages of development and of varying quality. But there is a large variety of password managers out there, so which one should we be using.

As 8jean commented above, looks like /usr/sbin/chpasswd might be the easiest way. Otherwise I’d have gone with noha’s comment of using functions like fgetpwent() — or fgetspent() for dealing with the shadow file — to walk the list of users and modify the record(s) I need to change.

In general, web-based password managers expose a whole new attack surface that is not present in regular password managers. A 2014 study by University of California researchers showed that, out of five password managers studied, every one of them was vulnerable to at least one of the vulnerabilities studied. LastPass was, in particular, vulnerable to a cross-site request forgery (CSRF) attack that allowed an attacker to bypass account authentication and access the encrypted database.

Unless you really have a big performance problem with this, you’re better off relying on the existing code and experience rather than trying to duplicate the existing code. At some level, something is going to have to “programmatically walk the files” no matter what. The best bet is to exec the passwd command with the appropriate arguments and let it worry about the file handling, crypt, and file locking issues.

The short answer is “viable but problematic. Problematic because the 16GB memory limit slows me down regularly, and because the 2015 MacBook Pro does not tolerate heat well at all.

To confirm this I tried again with a second disk, being very careful at each step from initial format to APFS (and verifying the format) to selecting the disk in the Time Machine prefs, and sure enough it too was reformatted back to HFS+. So we’ve been waiting all these years for a new file system (which doesn’t even include user data integrity checks) for this. When I selected the external disk in the Time Machine preference I got a panel telling me the disk format (APFS) was not compatible and it would ‘erase’ the disk if I proceeded. Since it was a blank disk anyway I accepted and then after an hour it completed the first Time Machine backup. When I then checked Disk Utility I discovered that it had been re-formatted back to HFS+ before performing the backup.

In particular, in my Mercedes Sprinter photography adventure van (see setup), I just want to connect my NEC PA302W wide gamut professional display to the computer; an extra 15 watts for the Thunderbolt 3 Dock makes sense only if I need its other ports, which I do not need on the road, or at least do not need except briefly. Aside from cost, that is a key reason why I am using a 2015 MacBook Pro and a 2015 iMac 5K—not the 2017 models which have Thunderbolt 3 ports and no Mini DisplayPort. So I am loathe to chew up 15 watts just to have the display connected (the display itself takes 90 watts which is bad enough).

I’m still investigating a VESA mount iMac 5K including products like the Tether Tools Rock Solid VESA iMac Stand Adapter so as to not stow/unstow, but those solutions still will subject it to harsh shock and vibration and so I think they might not be viable.

Since you can’t change Windows 10, only a new version of Mint will help. Apparenly, Microsoft changed something in Windows 10, making Mint think it’s hibernated. It’s likely that reverting to Windows 7 will help, because the status of the disk will be maintained with the logic from Windows 7 again. It’s worth a try anyway.

I am not a fan of release-by-calender-for-iPhone-quality-be-damned management. As usual, Apple has rushed out a macOS release with incompetence in testing, just as over the past 5 years. Incompetence is one thing; incompetence with security is an order of far worse.

I assume Apple will eventually implement Time Machine using APFS, and *maybe* add data integrity later if they haven’t painted themselves into a corner at the foundational design, but for now there doesn’t seem to be much benefit for the user with High Sierra. But at least we’ll get animated poop emojis.

Feb 11, 2016 · In this video I show how to do a triple boot with Windows 10, Ubuntu 14. This method maintains Windows 10 as the primary OS as. 3, and Linux Mint 17.

But in prior use, I’m pretty sure I’d damage my ports quickly by inadvertant pressure; even just inserting regular USB plugs weakened the ports and made them sloppy over time. When I have traveled over the years, I never worked at a desk, although that will change now with my photography adventure van. I’d rather see some cable arrangement for strain relief, rather than a make-pretty direct-attach. If sitting at a desk is always the use case, then AC power is available, and the OWC Thunderbolt 3 Dock is a far more robust solution. The key issue I see is no strain relief—direct attachment could damage the ports on the MacBook Pro if any torque is applied (such as a modest bump downards or upwards), as well as a too-wide form factor for use in some situations.

In addition to these, it is possible to build PostgreSQL for an unsupported CPU by disabling spinlocks. PostgreSQL works on any of the following instruction set architectures: x86 and x86-64 on Windows and other operating systems; these are supported on other than Windows: IA-64 Itanium (external support for HP-UX), PowerPC, PowerPC 64, S/390, S/390x, SPARC, SPARC 64, ARMv8-A (64-bit)[57] and older ARM (32-bit, including older such as ARMv6 in Raspberry Pi[58]), MIPS, MIPSel, and PA-RISC. 5), M68k, M32R, NS32k, and VAX. It is also known to work on Alpha (dropped in 9.

You may want to vary the local version string, for different configurations that you try, to distinguish them also. Before you go too far, use the “General Setup” menu and the “Local version” and “Automatically append version info” options to add a suffix to the name of your kernel, so that you can distinguish it from the “vanilla” one.

Other types of constraints (unique, primary key, and foreign key constraints) are not inherited. As of 2010[update], this feature is not fully supported yet – in particular, table constraints are not currently inheritable. All check constraints and not-null constraints on a parent table are automatically inherited by its children.

First of all, thanks for the tutorial. I installed the new kernel using the first method (make install), everything was ok and the command “uname -a” shows my new kernel running; but the command “dpkg –get-selections|grep linux-image” don’t show the new kernel. Is possible to register the new kernel with dpkg when the compilation was as I did.

[34] These can take the form of any data source, such as a file system, another RDBMS, or a web service. PostgreSQL can link to other systems to retrieve data via foreign data wrappers (FDWs). This means that regular database queries can use these data sources like regular tables, and even join multiple data-sources together.

These can be discrete ranges (e. The built-in range types available include ranges of integers, big integers, decimal numbers, time stamps (with and without time zone) and dates. All integer values 1 to 10) or continuous ranges (e. 2, a data type that represents a range of data can be used which are called range types. Any point in time between 10:00 am and 11:00 am). Starting with PostgreSQL 9.

PostGIS adds support for geographic objects in the PostgreSQL database. This document describes the process for installing PostGIS and creating a template PostGIS.

If your old installation is missing you could always (I hope so, I've never used Arch Linux) re-install it without overwriting the old data directory.

SELECT * FROM ONLY parent_table;. Adding a column in the parent table will cause that column to appear in the child table. Data in child tables will appear to exist in the parent tables, unless data is selected from the parent table using the ONLY keyword, i. Tables can be set to inherit their characteristics from a “parent” table.

Triggers are events triggered by the action of SQL DML statements. For example, an INSERT statement might activate a trigger that checks if the values of the statement are valid. Most triggers are only activated by either INSERT or UPDATE statements.

When an application does a get or put to/from an S-3 bucket, only the units that comprise that bucket need to be on.   This means that the rest of the system can be powered off to both save power and cooling and to extend the life of the unit.   This was one big difference I saw between the ArcticBlue unit and Lattus.   Lattus does not appear to have any power down features.   This is why they are advertising a 7-year lifespan for this product and not a 3-year lifespan.

You can optionally set a flag to scan for files recursively. See the Companion Plugin documentation for more details. If you have a directory full of files you wish to add to SuperContainer, you can either copy them to the directory where SuperContainer stores its files, or use the companion plugin function SCScanDirectory to return a list of files in a directory.

Even if you are the only root user, you need the syntax checking, so use “visudo”. You use “visudo” to edit the sudoers file. There are two reasons for that- it prevents two users from editing the file at the same time, and it also provides limited syntax checking.

The command (syntax: ssh hostname) opens a window on your local machine through which you can run and interact with programs on the remote machine just as if it were right in front of you. You can use the remote computer’s software, access its files, transfer files, and more. Linux’s ssh command allows you to log into and work on a remote computer, which can be located anywhere in the world.

The home directory is named after the user account, so the above example is what the value would be if you were logged into the server with an account called demo. This directory is within a directory called /home, which is itself within the top-level directory, which is called “root” but represented by a single slash “/”.

Awk will execute a code block only if the preceding boolean expression evaluates to true. We can place any kind of boolean expression before a code block to control when a particular block is executed. There are many other ways to selectively execute a block of code. If the first field of the current line is not equal to fred, awk will continue processing the file and will not execute the print statement for the current line:. The following example script will output the third field of all lines that have a first field equal to fred.

If instead you do awk ‘{stuff}’ infile > outfile there’s only one pass through the file. Bash: doing cat infile | awk ‘{stuff}’ > outfile causes each line in the input file to be processed twice, once by cat, and once by awk. If you’re processing big files, this can be significant.
