I have recently switched from firefox to google chrome on Ubuntu 16.04.  The keyring application is really starting to annoy me.  It keeps prompting me for password for no apparent reason.  Also google chrome randomly seems to forget passwords for some sites.  I would like to completely disable the keyring feature and have it just remember my passwords without me needing to enter another password.  I do not care to much about security since this is my personal system that no one else has access to.  How can I make chrome remember my passwords without every prompting me with keyring.
Whenever Ubuntu boots up, a dialogue pops up asking me to unlock my default keyring. Is there some way this can unlock automatically through PAM or some other magical way?
How can I write multiple lines in a subscript? Is there a way to force a line break inside a math mode text?  My example:  \[   \underbrace{....}_\text{Some long text that should be multiline} \]   Trying  \text{Some long text that\\ should be multiline}   Didn't do the trick. Run Script on Wakeup? Exporting Data From Salesforce - REST or SOAP? We have a requirement where we need to export records from salesforce tables into our application programmatically. I am reading on the various API's for data integration from salesforce mainly SOAP vs REST API's.  From what I understand, REST should be used when the web service requests are from mobile devices or browser based clients (since they understand JSON). Is that true? If that's the case how do Bulk REST API's fit the bill (since they are meant for bulk data transfers)?  I would like to get your thoughts on what are pros and cons in using SOAP or REST API's to export data records. Note that the requests are being made a java ee server application programmatically. After retrieving the records (probably in batches) from salesforce records we process (validate, filter etc) them and load them in our internal tables.  Thanks. I remember my English teacher saying that there are only two valid ways to make a one-word sentence:   A question:      Why? Where?  A command:     Go! Stop!    Is this correct? extended stars-and-bars problem(where the upper limit of the variable is bounded) Are there any journals that pay reviewers? Being a young researcher myself I received a comment from my colleague that some of the journals are paying reviewers for the reviewing process.  When I gave it a thought, it started to make more sense. In case of high quality, respected journal, an institution may consider itself privileged to have a reviewer of such journal and allow the reviewer to dedicate small proportion of his/her daily activities just on the reviewing process.  The reviewer being paid, has more obligations to provide thorough in depth review.  Does that hold true for some journals or is it just a myth? Unknown apps/processes with number only are shown in data usage A mysterious app named &quot;10102&quot; shows up in my data usage. It bears only the standard Android app icon (the Bugdroid logo with a cube on its torso). From what the graph tells me, it has used 36 megabytes of data in the background and zero on the foreground. I think I haven't uninstalled anything for months. Is it malware? I haven't sideloaded anything and only authorized my laptop as a USB debugger. If it's malware, how do I remove it? I have no idea how to find its package name and 10102 isn't in the list of downloaded apps in settings. I'm running stock &amp; never-been-rooted Android 4.4.4 on Nexus 4. Will I lose previous purchases when I change country in iTunes I lived in country A for a few years, and made a number of purchases on the iTunes store for that country. I have now moved to country B, and want to start using the iTunes store from country B. If I change the country in my account settings, will I lose all my previous purchases, or will I still be able to re-download my purchases from country A from iCloud? How to fix byte array java.lang.NullPointerException Showing $\left(1+\frac{1}{n}\right)^n$ is an increasing sequence by comparing the binomial expansions term by term So I know that showing $\left(1+\frac{1}{n}\right)^n$ is an increasing sequence has probably appeared on this site about 100 times, but my professor said he thinks the induction step is most easily seen if you expand this out and compare the summation term by term. I tried this and I did not what see why the inequality was obvious. Can somebody help me out here? Thanks! Obligatory: This is not a duplicate of , which is concerning the much older duplicate closure process.  Have a gander at . Notice anything weird?  The Community♦ user was invoked by the question asker to self-close as a duplicate (presumably of the comment below, which links to ), but the list of duplicates is entirely empty. So it would seem the question asker was able to close their own question as a duplicate of... nothing?  Screenshot, in case the post is altered later:    Any idea what happened here? How does one experimentally determine chirality, helicity, spin and angular momentum of a fundamental particle? I want to make it so I always have 50 entities in an area. So when 1 dies/despawns/leaves the area I want it to detect that and summon in a new entity, and yes I do want them to die/despawn/leave the area so preventing those things is not an option. I applied for a standard visitor visa to the UK for seven days. I earn £278/month and have been working at the same organization for more than a year. I have saved up enough funds for the trip and I attached bank statements to prove it. The ECO refused my visa stating:      I note that you stated that your trip to the UK will cost you £1100, this is approximately 4 times your monthly income. I do not find it credible that you spend this amount on a trip.   I am a single woman, with no financial responsibilities and I saved up for this trip because I really wanted to visit the UK.  How do I prove to the ECO and the authorities that spending £1,100 for my trip wouldn't have caused me any financial harm neither would I have had to access UK government funds?    Another concern of mine is that if I reapply without the partial funding of my father or get sponsored by a different person, does the amount given by my father previously cause hindrance in my visa application?  Won't they still reject it on the basis of my pay being too insignificant? How does the clean Installation of Windows 10 after the free upgrade work? I have not found any information from MS - only speculations from people like me, so I hope someone here has had better findings.  When I upgrade a qualified version of Windows to Windows 10 and then want to do a clean install, I've heard that the installer won't ask for a key. But what if my HDD is formatted before I attempt the clean install? How does Windows 10 try to detect the valid "upgraded" status? It seems that it doesn't in such a case, at least as far as I've tested.  So my question is: In that (or a similar) scenario: How do you clean install Windows 10?  In my case it's actually even more complicated. I'm from Germany so I can re-use OEM-licenses due to law. I have two qualified Windows OEM licenses which I both installed in a VM on my Linux installation and upgraded both to Windows 10.  Now I want to install one of them onto my bare physical machine - how would that be possible? Is there an official way of doing this or do I need to wait for those unofficial "backup license"-tools being updated to work with Windows 10? This question is a sequel of sorts to my  about .  In the paper, the authors performed molecular dynamics (MD) simulations of parallel-plate supercapacitors, in which liquid resides between the parallel-plate electrodes.  The system has a "slab" geometry, so the authors are only interested in variations of the liquid structure along the $z$ direction.  In my previous question, I asked about how particle number density is computed.  In this question, I would like to ask about how the electric potential is computed, given the charge density distribution.  Recall that in CGS (Gaussian) units, the Poisson equation is   $$\nabla^2 \Phi = -4\pi \rho$$  where $\Phi$ is the electric potential and $\rho$ is the charge density.  So the charge density $\rho$ is proportional to the Laplacian of the potential.  Now suppose I want to find the potential $\Phi(z)$ along $z$, by integrating the Poisson equation.  How can I do this?  In the paper, on page 254, the authors write down the average charge density $\bar{\rho}_{\alpha}(z)$ at $z$:  $$\bar{\rho}_{\alpha}(z) = A_0^{-1} \int_{-x_0}^{x_0} \int_{-y_0}^{y_0} dx^{\prime} \; dy^{\prime} \; \rho_{\alpha}(x^{\prime}, y^{\prime}, z)$$  where $\rho_{\alpha}(x, y, z)$ is the local charge density arising from the atomic charge distribution of ionic species $\alpha$, $\bar{\rho}_{\alpha}(z)$ is the average charge density at $z$ obtained by averaging $\rho_{\alpha}(x, y, z)$ over $x$ and $y$, and $\sum_{\alpha}$ denotes sum over ionic species.  The authors then integrate the Poisson equation to obtain $\Phi(z)$:  $$\Phi(z) = -4\pi \sum_{\alpha} \int_{-z_0}^z (z - z^{\prime}) \bar{\rho}_{\alpha}(z^{\prime}) \; dz^{\prime} \; \; \; \; \textbf{(eq. 2)}$$  My question is, how do I "integrate the Poisson equation" to obtain equation (2)?  How do I go from  $\nabla^2 \Phi = -4\pi \rho$ to equation (2)?  In paricular, where does the $(z - z^{\prime})$ factor come from?   Thanks for your time.
