Spectre protection () was released for Kernel 4.9.77 and 4.14.14 by the Linux Kernel team on January 15, 2018. The Ubuntu Kernel team only released  on January 17, 2018 and have not published kernel version 4.14.14. For the Meltdown patches (KPTI-&gt;KAISER-&gt;KASLR) the Ubuntu Kernel team released the  updates at the same time for 4.9 and 14.14 but the Spectre patch is missing in 4.14:  4.9.74 Jan 2nd 9:10pm ....... 4.14.11 Jan 2nd 10:40pm 4.9.75 Jan 5th 4:20pm ........ 4.14.12 Jan 5th 5:40pm 4.9.76 Jan 10th 10:20am .... 4.14.13 Jan 10th 10:50am 4.9.77 Jan 17th 10:20am .... 4.14.14 Missing  Mainline/Stable Ubuntu Kernel version 4.14.14 is still missing as of Jan 20th 5:46pm. Three days late and counting... I like to test the latest stable kernels and this is even more important now with the Spectre security hole. I've googled for reasons but came up empty handed. Is there a newsletter or something that would explain why? Or is it as simple as someone forgot to push a button? NOTE: Spectre protection is not being provided for LTS Kernels 4.4 and 3.18 by the Linux Kernel team however they have updated sysfs to indicate Spectre vulnerability. So far the only LTS Kernel versions offering Spectre protection are 4.9 and 4.14. Current Release Candidate (experimental kernel) 4.15 will soon have Spectre protection. Ubuntu 18.04 (Bionic Beaver) will be based upon 4.15 in April when it is no longer a Release Candidate and becomes a Mainline/Stable Kernel.  End of Story Thanks to Thomas Ward's help I got in touch with the Ubuntu Kernel Team and Mainline/Stable Ubuntu Kernel version 4.14.14 was published January 20, 2018 at 1:10pm.
Any questions relating to status updates, or asking if anything is going to be patched for these vulnerabilities should be closed as duplicates of this question.    are in the news right now and sound pretty severe. I don't see any security updates from Ubuntu that cover these vulnerabilities.  What is Ubuntu doing about these vulnerabilities, and what should Ubuntu users be doing?  These are CVE-2017-5753, CVE-2017-5715 and CVE-2017-5754.
How do I install the ubuntu-restricted-extras package? dd aplied to dev USB before connect corrupt /dev/sdX and dont work I have a USB where I'm coping an ISO of 5 Mb aprox with a small OS with its own grub. If I connect the device and check it sudo fdisk -l I get:  ... Device     Boot Start   End Sectors  Size Id Type /dev/sdb1  *        1  9551    9551  4.7M cd unknown   If I copy with dd the ISO sudo dd if=my_os.iso of=/dev/sdb   14852+0 records in 14852+0 records out 7604224 bytes (7.6 MB) copied, 0.538487 s, 14.1 MB/s   It works perfectly. An boot from BIOS in other PC.  The problem is, sometime I forget to connect the USB after update the BIOS, so I do ff WITHOUT the USB connected,  the output is:  14852+0 records in 14852+0 records out 7604224 bytes (7.6 MB) copied, 0.00987684 s, 770 MB/s   Now, the /dev/sdb register is corrupted, the copy speed (770 MB/s) have no sense, and cannot user again dd until reboot.  I have tried to repair it with ddrescue and it doesn't work  sudo ddrescue /dev/zero /dev/sdb conv=noerror,sync   My question is, what is happening exactly and if is possible, how to repair /dev/sdb to avoid reboot and dd start working again?  Thanks. XIV pages in page counts? I am trying to make folder that everyone can view and can't copy,modify.    For all answers.I thinking about specially ms office files. I tried following methods  Software  - copy protect    - anti copy    This method can't protect save as and upload  MS office macro    Users can enable,disable macros.  MS office restriction    This is best choice but can't protect from file uploading.   Almost I found the solution. Way is combination of MS office restriction and restrict access from browsers using firewall or antivirus. But I don't exact how to do this. The list view of Nautilus 3.6 shows the dates files were modified in a variety of ways: the hour and minute if modified on the current day, and the month and day if modified during the current year, and the year tacked on if modified during a previous year. I would like to see the entire date and time consistently on all the files (e.g.: Sat 20 Apr 2012 01:28:34 PM EDT).  I had this set up before, but I can't figure out how to do so with version 3.6. I did find this question, but the answers no longer apply to Nautilus 3.6:   How can I do so in Nautilus 3.6+? So I have an SQL dump file that needs to be loaded using mysql_query(). Unfortunately, it's not possible to execute multiple queries with it.  -> It cannot be assumed that the mysql command-line client (mysql --help) is installed -- for loading the SQL file directly  -> It cannot be assumed that the mysqli extension is installed  /* contents of dump.sql, including comments */ DELETE FROM t3 WHERE body = 'some text; with semicolons; scattered; throughout'; DELETE FROM t2 WHERE name = 'hello'; DELETE FROM t1 WHERE id = 1;   The explode() below won't work because some of the dump content's values contain semicolons.  $sql = explode(';', file_get_contents('dump.sql')); foreach ($sql as $key =&gt; $val) {     mysql_query($val); }   What's the best way to load the SQL without modifying the dump file? True displacement in EEVEE? I have a Blender 2.8 scene with animated true displacement. It is created using material nodes and works fine in Cycles. However, EEVEE doesn't displace my meshes truly, only normals are changed. Is it possible and how to solve the problem now or in the future? Converting vector layer to raster using QGIS? In qgis in the raster menu there is an item "convert vector to raster".  This behaves strangely - I do not understand how it is supposed to work.  I can select a vector file, an attribute and an output raster. But, for some reason the output file is only accepted if it exists and even if I select an existing raster nothing seems to happen.  Also I do not understand how the program knows what kind of raster to create, what cell-size, projection etc.  How can I convert vector to raster? What is the domain of $x^x$ as a real valued function? Consider the function $f(x) = x^x$.  Wolfram alpha tells me that this function's domain is $x : x&gt;0$, $x \in \mathbb{R}$. I can't see why it cannot be defined for a number like $(-2)$. I mean $(-2)^{-2}=0.25$, the same Wolfram Alpha told me. I realize that fractional powers for negative numbers may cause problems, but it could be defined for integers. Thanks for any help. Why do some bad traits evolve, and good ones don't? How to calculate $\lim_{n\to\infty}(1+1/n^2)(1+2/n^2)\cdots(1+n/n^2)$? How can we compute the following limit:     $$\lim_{n\to\infty}(1+1/n^2)(1+2/n^2)\cdots(1+n/n^2)$$   Mathematica gives the answer $\sqrt{e}$. However, I do not know to do it. How can I check the actual size used in an NTFS directory with many hardlinks? On a Win7 NTFS volume, I'm using cwrsync which supports --link-dest correctly to create "snapshot" type backups. So I have:  z:\backups\2010-11-28\cygdrive\c\Users\... z:\backups\2010-12-02\cygdrive\c\Users\...   The content of 2010-12-02 is mostly hardlinks back to files in the 2010-11-28 directory, but there are a few new or changed files only in 2010-12-02. On linux, the 'du' utility will tell me the actual size taken by each incremental snapshot. On Windows, explorer and du under cygwin are both fooled by hardlinks and shows 2010-12-02 taking up a little more space than 2010-11-28.   Is there a Windows utility that will show the correct space acutally used? How can slightly blurred photos be improved in post processing? How do I escape a single quote ( ' ) in JavaScript? Is there a way to do concurrent editing? Is there a MediaWiki-like method for supporting concurrent editing of text bodies in Drupal 7?  If no feature currently exists, what are some decent PHP diff libraries that could be wrapped up by a Drupal module that could do the job? If one were to take a similar path as  in shooting candid street photography today, should they be concerned about laws or other realistic norms of today? I am wondering specifically in the US speaking broadly of all states. I am not looking for legal advice, but anything that one photographer to another would caution against as potentially being grey or obviously illegal.  Similar previous question: Non-algebraically closed field in which every polynomial of degree $<n$ has a root My problem is to build, for every prime $p$, a field of characteristic $p$ in which every polynomial of degree $\leq n$ ($n$ a fixed natural number) has a root, but such that the field is not algebraically closed.  If I'm not wrong (please correct me if I am) such a field cannot be finite, by counting arguments. But on the other hand, the union of all finite fields (or of any ascending chain of finite fields) of characteristic $p$, which is what I get if I start with $F_p$ and add a root to each polynomial of degree $\leq n$ in each step, is the algebraic closure of $F_p$, hence algebraically closed. I don't see how I can control this process so that in the end I get a field that is not algebraically closed.  Any hint will be welcome. Thanks in advance. single word that means which can be constructed at home Story [novel, novella?] that featured faster-than-light or hyperdrive gained from observing distant drive use, also had a sentient star I have little recollection when I read this, but it started with people observing indications of some special engine use many lightyears away, and it led them to 'reverse-engineer' the traces to create their own drive.  Had the usual tropes of international crew-selection for first-voyage.  Somewhere in the travel, they encounter a sentient star or quasar.  When they get back hundreds/thousands of years later, they arrive to an uncaring Earth that no longer pursues space-travel. Number of ring homomorphisms from $\mathbb Z_{12}$ to $\mathbb Z_{28}$. Question:      Find the number of non trivial ring homomorphisms from $\mathbb Z_{12}$ to $\mathbb Z_{28}$. ($f$ is not necessarily unitary, i.e., $f(1)$ need not be $1$.)    Suppose $f$ is a ring homomorphism from $\mathbb Z_{12}$ to $\mathbb Z_{28}$.  Consider $f$ as a additive group homomorphism.  Let $k= |\ker f|$ and  $ t = |\operatorname{im}(f)|$. Then $k\mid 12$ and $t\mid 24$ and $kt=12$, by first isomorphism  theorem of groups.  There are two possibilities $k=3$, $t=4$   and $k=6$, $t=2$.  For the first case $f$ should map $1$ to an element of the subgroup generated by $7$ as there is a unique subgroup of $\mathbb Z_{28}$ of order $4$ generated by $7$. For the second case $1$ has to map to $14$, for the same reasoning.  So there are at most two ring homomorphisms from $\mathbb Z_{12}$ to $\mathbb Z_{28}$. Question is how to check the possible maps which are ring homomorphisms.  Thanks.
