You assert that in Europe \" ;your CV is all that counts \" ;. That is, unfortunately, quite naive. The CV of your average student is simply not expressive enough to be \" ;all that counts \" ; - good grades are at best a weak indicator of research potential, and (despite your counterexample from France), also in many places in Europe many students have very good grades, to the extent of being low-value as a discriminator in hiring. Grades also do little to measure the soft factors such as motivation or being a good team player, which ultimately matter more than whether a student had an A or a B for some largely unrelated undergrad course.\r\n\r\nHow professors in Europe largely have dealt with this uncertainty is by personally asking the professors that the student worked with before what their impression of the student was - so you still have your \" ;recommendations \" ;, but not through written letters but through informal email or telephone exchanges. This was possible because traditionally, students in (at least central) Europe were not particularly mobile - most prospective PhD students did their undergrad in the same university, a close-by university, or a different university where the professors are already in close contact. Applicants from other places were often rejected outright. Now times are (slowly) changing and more and more PhD students come from abroad - and, lo and behold, suddenly formal recommendation letters are becoming important as well.\r\n\r\nAnother aspect that I am missing in your question that at least central and southern Europe has historically had a problem with *rampant* nepotism in academia. So I find it particularly curious that you draw Europe as a haven of objective hiring strategies.","906"],["Your implementation needs to be good enough to evaluate the concept you want to evaluate - no more, but certainly no less. What this means in practice is largely dictated by *what kind* of evaluation or experiments you want to do. I have basically seen four broad classes in Computer Science:\r\n\r\n - **Proof-of-Concept (PoC)**: you only want to show that your idea *can* be implemented, so you only implement your idea (often in a fairly naive or bare-bones manner). Note that this is often good enough for a quick demo, but not good enough for a paper (because reviewers usually feel that the conclusion that something can be implemented is not satisfactory by itself).\r\n - **Evaluation Prototype**: in addition to the PoC, you want to evaluate *how well* your idea works in some quantitative manner. For instance, if you are building some novel file system, you probably want to not only show that it can be implemented, but also that it works better in some dimension (e.g., faster) than existing systems. Your prototype can still be bare-bones, but you presumably need to build the core parts *well* because otherwise your evaluation may end up showing primarily that your prototype sucks. In a way, your prototype results show a sort of lower bound on how your idea works - that is, if your results are good your idea is validated, but if your results are not good, it may be because they idea does not work or your code is too bad of an implementation.\r\n - **User Study Prototype**: in addition to quantitatively evaluating your prototype, you may want to run one or more case or user studies with it, or conduct a controlled experiment. Now you need to improve your evaluation prototype with at least a limited amount of bells and whistles, because it is hard to run an expressive user study if your system is almost unusable to anybody but yourself. In this stage you may be adding a GUI and a bunch of features that are unrelated to your science, but which may be needed even in trivial practical usage.\r\n - **(Simple) Product**: the final stage is that you plan to actually release your implementation in some manner to the public. Maybe as part of an open source project, as a consulting delivery to a company, or even in the context of a spin-off company. You will now need to add many more bells and whistles unrelated to your science. Further, now you need to start caring about documentation, a release cycle, not doing breaking changes, etc., all of which are basically irrelevant as long as you are just building a prototype for your science.\r\n\r\nSo what does this mean for your project?\r\n\r\n > For example, if a \" ;novel \" ; work requires a persistence layer and a researcher uses a file based method e.g. csv. Will that be wrong? Will his architecture point to a database or a file system ?\r\n\r\nI generally suggest my students to follow a lean approach:\r\nwhat kind of experiment do you plan to do? Will it matter what kind of persistence layer the prototype has? If no, then build whatever you can do quickest and where you are most confident that it will work correctly - but keep in mind that even the simplest prototype can sometimes run through all the phases above, so at least plan for the possibility that you may need to swap out your persistence layer for something a little more state-of-the-art than a flat text file later on.","726"],["While the comments (and also Lyndon's answer) give you some ideas that you can try, I suspect the most realistic answer will be that converting a 2-column paper into a format that's slightly easier to read for you will not be worth the (considerable) effort on a consistent basis.

I actually learned this during the teacher's seminar that our university mandates for all tenure-track faculty, but it's actually applicable to all aspects of academic work.

Hence, we solve the normal equations, so that\\r\\n$$\\r\\nV^TAV\\\\beta = V^Tb\\r\\n$$\\r\\nFrom above, we know that $V^TAV=I$, so we really have that\\r\\n$$\\r\\n\\\\beta = V^Tb\\r\\n$$\\r\\nor that\\r\\n$$\\r\\nx = VV^Tb.\\r\\n$$\\r\\nNote, this holds regardless of the preconditioner $B$. In fact, we could take random vectors and $A$-orthogonalize them against each other and the same would hold. Really, the only thing that $B$ affects is the space. As long as $B$ helps cluster the eigenvalues of $A$, the algorithm performs well. Though, if $B$ is nonsymmetric, we may have to look at something like the pseudospectra to figure that out. I'm not entirely sure. Mostly, cluster the spectra.\\r\\n\\r\\nDo we lose anything with a nonsymmetric $B$? Probably. Normally, in CG, we have properties like $\\\\langle Br_i,r_j\\\\rangle = 0$ for all $i\\\\neq j$. I'm pretty sure that no longer holds. Also, we normally have $\\\\langle BAv_i,Av_j\\\\rangle=0$ for $|i-j|\\\\geq 2$. That may or may not hold. Really, any result that has $B$ I'd be suspicious of.\\r\\n\\r\\nAnyway, I'm pretty sure it's possible to code CG in a way that'd break everything with a nonsymmetric $B$.

Your goal here is to convince the committee that you are both, related to existing professors enough that you won't be the odd (wo)man out, and different enough not to be redundant.\\r\\n - Questions that target your teaching, most importantly which courses you could take over, which new courses you would introduce, and how these would enrich the current specializations and programmes. It's possible that they already have a concrete (set of) courses that they need you to teach, and then they may outright ask you if you would do that, and if so how.\\r\\n - Questions that target your funding acquisition plans. Which grants would you apply for initially? How much funding do you expect to be able to acquire? Are there any funds that you would bring with you? What group size would you expect to be able to maintain?\\r\\n - Questions regarding your package. You won't need to say a concrete salary figure at this point, but the committee will likely ask how many research staff you will ask for, and whether you have any particularly expensive other needs (e.g., a compute cluster, other equipment). Note that W3 professorships in Germany tend to be **large**, asking for at least 3+ staff as package to start negotiations with should be seen as normal.\\r\\n - Questions regarding your intentions w.r.t. this position. Would you be moving fulltime? Can you see yourself living in this place for the foreseeable future? Why is this position even attractive to you?

Those fall into two basic categories: fear of repercussion and ethics. Both categories are easy to understand. Clearly, it *may* work out great for me to cheat on tests and forge my data, but it *may also* easily be discovered and backfire on me - and if it happens, the consequences are typically dire enough that overall it is not worth the risk for most. Further, as academics we are nurtured in the thought that academic honesty is the foundation of science.

However, I tend to remind people that present-day academia, at least in science and engineering, is no ivory tower where people are completely protected from outside pressure and forces.

It is important here to not end up discriminating based on nationality, age, gender, or marital status, but there is no arguing that being the \\\" ;odd person out \\\" ; in an otherwise tightly knitted team will not be great for the motivation of the student.

Of course, if we used money that was given to us for some other cause (e.g., to conduct some fundamental research) it would be a different story.\\r\\n\\r\\nHowever, I have the impression that the issue here is something else entirely. Notably, I suspect that the OP got hired under the pretense of a regular postdoc (i.e., on a position that is usually considered a stepping stone for a professorship) and is now pushed into what is essentially an industry development job due to her/his specific skills. Such situations are not uncommon in industry - people get reassigned to different roles based on changing company needs all the time. However, in academia, this (while maybe legal) is a rather shady move.

If this is your absolute best, cream-of-the-crop paper and you are confident it will go through, then submitting to a weaker conference just because you did not want to wait will feel like waste down the road. If the A* conference felt like a long shot anyway, go ahead and submit now.\\r\\n - How likely are you to get scooped? If you are doing cutting-edge research in a trending topic, you may want to go for the A conference simply because you are afraid that somebody else may publish before you if you don't.\\r\\n - How important is timely publishing for your content? Many great research papers are in essence timeless, but occasionally one has produced a paper that is of value to the community right now, but which may be much less interesting in a year (e.g., some empirical studies in fast-moving fields are like that). In that case you should submit to the A conference now, because there is a very real danger that the paper will not be good enough for the A* paper in a year anyway.\\r\\n - How important is having the paper out soon for your career progression? E.g., if you are handing in your PhD in a year, or plan to be on the job market in a year, or plan to hand in this selective personal grant in the next year, then having another published A paper may be better than a potential A* paper that comes \\\" ;too late \\\" ;.\\r\\n - How much value is (in your field and your circles) placed on the \\\" ;esteem \\\" ; of the venue? That is, what do you estimate how much more valuable the same paper will be for your career if published in an A* venue rather than an A venue? In a perfect world, it would not matter.

Specifically prefer people that know you from research projects or other \\\" ;outside the classroom \\\" ; activities.

This should be obvious, but keep in mind that everybody does that, so the overall level of enthusiasm in letters is *very* high. Even a well-reasoned positive-ish letter with some negative aspects may already be a kiss of death for your application.\\r\\n - Prefer **people that are in a position to write a plausible recommendation**. In practice, this usually means that more senior and/or more well-known recommenders are better than less experienced ones, simply because a statement like \\\" ;among the best student I have had \\\" ; means much more if the writer is a senior professor than an assistant prof. in his first year.\\r\\n - Prefer **people who know how to write a recommendation letter**. Especially if you are currently located in a different cultural region, it is well possible that your letter writers are not overly familiar with how a recommendation letter is *supposed* to be written. The end result may be a letter that is *meant* to be positive, but which is perceived as lukewarm or unprofessional.

That is, there should not be any doubt that you would be able to receive habilitation easily if you applied for it with your current CV. This is generally no problem for candidates that already hold a position comparable to a W2 professorship (say, an associate professor in the US or a Senior Lecturer in the UK), but if you are currently a postdoc it is important that you underline your independence in research and teaching, your standing in your community, as well as your ability to acquire grants and external funding (i.e., the criteria among which habilitation is usually decided).\\r\\n\\r\\nAnother factor may be academic age - in many cases academically older candidates will find it easier to communicate that they are in a career stage comparable to W2 professor than excellent younger ones. I have the impression that in Germany many commissions either do not, or fail to, properly normalize qualifications based on academic age; that is, they will often prefer more modestly qualified senior candidates over very promising younger ones.\\r\\n\\r\\nFinally, another challenge may be language.

Why do schools apply such strategy?\\r\\n\\r\\nOne instance why this may happen is for core courses that *need* to be taught, and for which no clearly matching faculty is available. My department, for instance, has a very clear focus on applied and practical computer science. For some fundamental courses, we simply *do not* have obviously matching faculty, and no plans to hire people for this profile either. This leaves us with the options of either finding external people to teach the course (preferred if said people exist and funding for paying the external person is available), or making one of our faculty from a different field teach the course, fully knowing that (a) the faculty will not be happy and (b) that (s)he will probably not do an outstanding job either. Part of convincing said faculty is usually also a promise that (s)he needs to teach this \\\" ;foster \\\" ; course only one or two times, before passing the token on to somebody else.\\r\\n\\r\\nAn alternative reason for rotating teachers is that there *is* more than one faculty that can teach a course, but the course is highly disliked and an agreement was established that multiple people take turns teaching it. I have seen this happen for courses such as \\\" ;Introduction to Programming \\\" ;, that many people are in principle qualified to teach, but few really *want* to teach.\\r\\n\\r\\nFinally, it may be that the school (correctly or incorrectly) assumes that rotating a course will indeed improve the quality of the course or add in some way to it. For instance, in my old alma mater, we had the concept of \\\" ;AK courses \\\" ; ( \\\" ;selected topics in SOMETHING \\\" ;). These courses were advanced courses with no fixed content, only a sort of framework or direction. Every year, a different professor would be teaching it, and give it a completely different spin depending on his own current research interests. You could do the same AK multiple times, assuming that the professors agreed that those years were indeed sufficiently different.\",\n \"197\"\n ],\n [\n \"I can't really say that I \\\" ;get \\\" ; the concern of the co-author here, but I am aware that different people have dramatically different views on privacy than I do.\\r\\n\\r\\nIn general, this is definitely a question that you can ask the Editor-in-Chief without concern. However, depending on how many submissions the journal in question gets, it is possible that the EiC may be rather uncompromising upfront. For some top-level journals, submissions are a dime a dozen, and I have seen editors that see little need to engage in potentially time-consuming discussions with authors prior to even seeing an acceptable manuscript. Hence they may just point to an existing policy if there is one, without much further thought.\\r\\n\\r\\nHence, another possibility would be to just submit the paper regularly, and delay the problem until the paper proofing phase. If your paper is deep enough into the process that the question actually becomes urgent, it seems exceedingly likely that the editor and/or responsible persons from the publisher's side will be willing to compromise over such a triviality rather than reject the paper. For instance, they could allow your co-author to have a placeholder rather than his photo, and/or have a very short bio text along the lines of \\\" ;Dr is currently a research engineer at GoodStuff Inc.

In my field (applied CS), uncertainty about methods is virtually never explicitly mentioned in papers (that is, it is very rare that an author would write a variation of \\\" ;we used method A, but method B would be promising as well but we did not try it \\\" ;). Expressing a certain caution about results is common, though ( \\\" ;the results appear to support hypothesis C, but further research may be required \\\" ;). My community is also very big on describing limitations of experimental design in a dedicated section, but many other CS fields don't do this either.\\r\\n\\r\\nIt is very honorable that you try to be truthful and conservative, but I suggest that you trust your advisor's experience on the expectations of the life science community on how manuscripts are typically written.

Frankly, it's also not like a lot of harm is done by not describing obvious alternative methods or limitations.

You assert that in Europe \\\" ;your CV is all that counts \\\" ;. That is, unfortunately, quite naive. The CV of your average student is simply not expressive enough to be \\\" ;all that counts \\\" ; - good grades are at best a weak indicator of research potential, and (despite your counterexample from France), also in many places in Europe many students have very good grades, to the extent of being low-value as a discriminator in hiring.

Applicants from other places were often rejected outright. Now times are (slowly) changing and more and more PhD students come from abroad - and, lo and behold, suddenly formal recommendation letters are becoming important as well.\\r\\n\\r\\nAnother aspect that I am missing in your question that at least central and southern Europe has historically had a problem with *rampant* nepotism in academia.

What this means in practice is largely dictated by *what kind* of evaluation or experiments you want to do. I have basically seen four broad classes in Computer Science:\\r\\n\\r\\n - **Proof-of-Concept (PoC)**: you only want to show that your idea *can* be implemented, so you only implement your idea (often in a fairly naive or bare-bones manner). Note that this is often good enough for a quick demo, but not good enough for a paper (because reviewers usually feel that the conclusion that something can be implemented is not satisfactory by itself).\\r\\n - **Evaluation Prototype**: in addition to the PoC, you want to evaluate *how well* your idea works in some quantitative manner. For instance, if you are building some novel file system, you probably want to not only show that it can be implemented, but also that it works better in some dimension (e.g., faster) than existing systems. Your prototype can still be bare-bones, but you presumably need to build the core parts *well* because otherwise your evaluation may end up showing primarily that your prototype sucks. In a way, your prototype results show a sort of lower bound on how your idea works - that is, if your results are good your idea is validated, but if your results are not good, it may be because they idea does not work or your code is too bad of an implementation.\\r\\n - **User Study Prototype**: in addition to quantitatively evaluating your prototype, you may want to run one or more case or user studies with it, or conduct a controlled experiment. Now you need to improve your evaluation prototype with at least a limited amount of bells and whistles, because it is hard to run an expressive user study if your system is almost unusable to anybody but yourself. In this stage you may be adding a GUI and a bunch of features that are unrelated to your science, but which may be needed even in trivial practical usage.\\r\\n - **(Simple) Product**: the final stage is that you plan to actually release your implementation in some manner to the public. Maybe as part of an open source project, as a consulting delivery to a company, or even in the context of a spin-off company. You will now need to add many more bells and whistles unrelated to your science.

Will it matter what kind of persistence layer the prototype has? If no, then build whatever you can do quickest and where you are most confident that it will work correctly - but keep in mind that even the simplest prototype can sometimes run through all the phases above, so at least plan for the possibility that you may need to swap out your persistence layer for something a little more state-of-the-art than a flat text file later on.\",\n \"726\"\n ],\n [\n \"While the comments (and also Lyndon's answer) give you some ideas that you can try, I suspect the most realistic answer will be that converting a 2-column paper into a format that's slightly easier to read for you will not be worth the (considerable) effort on a consistent basis.

In my field (Computer Science), it is uncommon but not unheard-of for workshops to have what is called \\\" ;post-proceedings \\\" ;. That is, authors submit an initial version of their manuscript, present at the workshop, and then have a chance to revise for the actual published paper. In this case it is possible, maybe expected, that you actually improve your paper based on the comments you received (although usually no additional review happens at this point).\\r\\n\\r\\nHowever, most venues don't have that. The more usual case is that you submit a paper and the proceedings are already published when the conference starts. In this case, you obviously have no chance to revise your paper, because by the time the conference happens the paper is already available on archival sources. The advantage, of course, is that the paper is available for people to read during, or even before, the conference.\\r\\n\\r\\n > Aren't workshops/conference mechanisms to get feedback? \\r\\n\\r\\nFor conferences in CS, this is most certainly *not* what conferences are for. In this field, conferences are a means to *communicate* the result of finished studies, not to get input on how to do them. Sure, you can get ideas for future work, but it will pretty much by definition be too late to change what you have already done. For workshops, things are a bit muddier, but in practice authors usually use the feedback they receive at workshops to improve the larger study that they are usually working on (which will be submitted to a conference or journal), not so much to improve the workshop paper itself.\",\n \"827\"\n ],\n [\n \"I wholeheartedly agree with JWH2006 that you should not immediately jump to assuming malice, but instead of forgetfulness the root of the issue could also be a *misunderstanding*. You don't really provide enough details that this can be judged by us, but often I have seen \\\" ;verbal agreements \\\" ; that both sides understood quite differently. For instance, you may have asked for \\\" ;help with finding a postdoc position \\\" ; and expected that your advisor would poke his colleagues, sit down with you and prepare your application material, and train you for the interviews, while he thought it just meant writing a nice letter for you. That is, maybe you are in a situation where your advisor *thinks* they are doing everything they agreed to do, while you see it has them reneging on their promise.\\r\\n\\r\\nThe solution to this problem is similar to what JMH2006 proposed - contact them and ask, very concretely, what kind of help you would like to get. Never go into accusations that they broke their promise (this won't end well, *especially* if they think they actually did everything they promised to do). Maximally, I would remind them of all the unpaid help you did for them, but more in a \\\" ;I did a favor for you, can you please do a favor for me now \\\" ; way, again not in an accusatory way.\\r\\n\\r\\nIf, after that, they still maintain that they can't or won't provide whatever help you feel you have been promised, I suggest the option.

Giving feedback on your work is part of the implicit deal that a senior person enters when enlisting the help of a PhD student on things like that.\\r\\n\\r\\n**Answer 2:**\\r\\n\\r\\nIn addition, *re-engineer* what they did to your text. You sent a full page of content and little of it made the cut. That is valuable information: apparently your text was, for one reason or another, not suitable. Read *very* carefully what the seniors decided to write instead: did they focus on different aspects? is their writing more polished in terms of language? is the tone different? was your original draft not aligned well enough with the rest of the proposal? is there anything else that reads notably different?\\r\\n\\r\\nWhat I did when I was learning the ropes (actually, I still do this sometimes when I work with somebody better than me at grant writing) is to very carefully re-construct how they build their argument, what they write, and what they *don't* write. If in doubt, I ask them directly, but I feel the exercise of figuring this out myself is a better learning experience than simply asking for feedback.\\r\\n\\r\\nAnother thing to keep in mind of this happens regularly is that maybe you need to ask more, or better, questions *before* starting to write the text. If the PI asks you to write about related work, discuss in advance what fields you should cover and in what detail. If you should describe a specific work package, run your thoughts on what it should entail briefly by the PI before writing it all down. A quick meeting is usually more productive than multiple iterations of text writing, and being efficient is usually very important when writing a grant.\\r\\n\\r\\nFinally, figure out whether *anything* related to your text actually made the cut. Sometimes, one just finds out when putting it all together that a specific section that sounded like a good idea during planning simply does not fit the proposal after all (for content or space restriction reasons). This is unfortunate, but still happens sometimes. In that case, maybe your writing was perfect, but your section simply still did not make the cut.

For your ultimate goal it matters little if you are successful or not in your postdoc. Consequently, I am not sure what good advice we can give you: if you want to move to the US, and this is a way to move to the US, what more is there to say?\\r\\n\\r\\n-----\\r\\n\\r\\nThat said, I can't help but wonder if there are not much more direct ways to achieve what you try to achieve.

At the very least this makes it explicit that you are actually making a trade-off when you burn the midnight candle at work. Keep in mind that, hopefully, other non-work things are important to you as well, so if you decide to burn 20 more hours on a paper that's basically done you are effectively trading off one thing you want to do for another. If you look at it this way it basically becomes an optimization problem - do I really want to proof-read this paper three more times to make sure that there are no typos in it, or do I rather want to spend this time on something else that is also important to me?\\r\\n\\r\\nA second thing I do is rigorous time keeping and time budgeting. I actually learned this during the teacher's seminar that our university mandates for all tenure-track faculty, but it's actually applicable to all aspects of academic work. Basically, one can always invest an infinite amount of time into every activity, so it is important to assign a budget of how much time one practically has for a specific activity (say \\\" ;I can only spend 6 hours to prepare a single lecture \\\" ;), and then do the best that is possible in that time. This may mean that you can't make the fancy flipped classroom work that you had in mind, or it may mean that this really interesting data analysis will need to wait for the next paper, but time is finite and ultimately a great paper that is never submitted is worse than a good paper that is.\\r\\n\\r\\nBut, again - if you feel like you can't bring yourself to make these trade-offs on your own, get **professional help** before you burn out completely and/or drop out of academia.\",\n \"605\"\n ],\n [\n \"Yes, this is completely ok, even recommendable.

Writing a thesis proposal in your field is one such genre. Before writing, it is key to understand what exactly your genre is.

Go over existing proposals (both, good and bad examples can be useful), and carefully examine not only what they write, but also how the argument is structured, what recurring phrases there are, in which order content is presented, and towards what audience they write.\\r\\n\\r\\nIn your case, it sounds like you have some misconceptions regarding, at least, the target audience and purpose of the text.

You need to surround the time in single quotes for the query, and also escape those quotes for powershell, because powershell treats things within un-escaped single quotes as literals, which meanns variables within single quotes are not expanded unless escaped.\\r\\n 3. Other times I've used XPath, it required greater/less than as & gt ; / & lt ; but here that would not work. Only the actual > < symbols worked.\\r\\n 4. The beginning of the Xpath query contains \\\" ;System \\\" ;, this does NOT refer to the event log type, it refers to the System branch of the event XML (screen shot below for an event from the Application log)\\r\\n\\r\\nSample\\r\\n\\r\\n $time1 = ((get-date).toUniversalTime()).addHours(-22)\\r\\n $time2 = ((get-date).toUniversalTime()).addHours(-24)\\r\\n $newest = get-date($time1) -f s\\r\\n $oldest = get-date($time2) -f s\\r\\n $newest\\r\\n $oldest\\r\\n foreach ($logName in \\\" ;Application Security System Setup \\\" ;.split( \\\" ; \\\" ;)) {\\r\\n \\tWEVTUTIL.EXE EPL $logName \\\" ;C:\\\\temp\\\\my$logName.evtx \\\" ; \\\" ;/q:*[System[TimeCreated[@SystemTime < =`'$newest`' and @SystemTime > =`'$oldest`']]] \\\" ; /ow:true\\r\\n }\\r\\n\\r\\n[![eventXML][1]][1]\\r\\n\\r\\n\\r\\n [1]: _URL_0_\",\n \"532\"\n ],\n [\n \"AD Partitions and DNS zones are different things.

You can't simple not use depth here because `find` prints the output from the top and since we are replacing things with `sed` before we `mv`, `mv` will result in a error for deeper subfolders.

Pipe the sorted list to `awk` to remove the counts from each line. Pipe the output to `sed`. The `p` option prints the input line and the rest of the `sed` command finds the **last** occurrence of \" ;thumbs \" ; and changes only it to \" ;thumb \" ;.

Also, create a shell script, let's call it `build_image.sh`, that runs your docker build command using `sudo`.\r\n\r\nAlso, on **serverB**, create a shell script that builds your code from source (if necessary).\r\n\r\nFinally, on **serverB**, create a shell script that calls your code build script, your docker build script and at the end runs your new docker image. Let call this script `do_it_all.sh`.\r\n\r\nMake sure that you `chmod 755` all shell scripts.\r\n\r\nNow, on **serverA**, you have a directory with the source code. `scp` that directory to **serverB** into the directory with the `Dockerfile`.\r\n\r\nNext, from **serverA** use `ssh` to call `do_it_all.sh` on **serverB**. This will build your code, build your image and deploy a container without the need for extra software, packages, git, DNS records, etc.\r\n\r\nYou can even automate this process using cron or something else to have nightly deployments, if you wish, or deployments under other conditions.\r\n\r\n**Example scripts/commands:**\r\n\r\nOn **serverB:**\r\n\r\nbuild_image.sh:\r\n\r\n #!/bin/bash\r\n sudo docker build -t my_image\r\n\r\nbuild_code.sh (optional, adjust to your code):\r\n\r\n #!/bin/bash\r\n cd /path/to/my/code\r\n ./configure\r\n make\r\n\r\ndo_it_all.sh:\r\n\r\n #!/bin/bash\r\n cd /path/to/my/dockerfile\r\n sudo docker stop my_container #stop the old container\r\n sudo docker rm my_container #remove the old container\r\n sudo docker rmi my_image #remove the old image\r\n ./build_code.sh #comment out if not needed\r\n ./build_image.sh\r\n sudo docker run -d --name my_container my_image\r\n\r\nOn **serverA:**\r\n\r\n scp -r /path/to/my/code serverB:/path/to/my/dockerfile\r\n ssh serverB '/path/to/my/dockerfile/do_it_all.sh'\r\n\r\nThat should be it.

Next, copy your `Dockerfile` and your build scripts and your code from **serverA** to **serverB** using `scp`. Then run `do_it_all.sh` on **serverB** from **serverA** using `ssh`.","324"],["**Solution:**\r\n\r\n 1[5-9][0-9]|200|7[0-4][0-9]|750\r\n\r\n**Explanation:**\r\n\r\nSince you have a very well defined ranges, the regex is fairly simple.\r\n\r\nIt can be broken up into two parts:\r\n\r\n 1. 150 **through** 199 **OR** 200\r\n 2. 700 **through** 749 **OR** 750\r\n\r\nSo, put together the regex will read as \r\n\r\n((150 **through** 199 **OR** 200) **OR** (700 **through** 749 **OR** 750))\r\n\r\nYour first number is 150, so we will have to match a '1' for the first digit followed by the range for the second digit which could be 5 though 9 (you don't want anything less that 150, so 4 and less are out) and also followed by the range for the third digit which could be anything from 0 to 9. This captures all numbers from 150 to 199.\r\n\r\nThe last number in the first range is 200, so we can just look for that. It is too different from the rest of the possibilities in the range, thus it is easier to look for specifically for it instead of trying to think of a complex way of including it in a regex range.\r\n\r\nThe second range follows the same patten but with different numbers. Again, we are looking for most of the numbers by using the regex range and looking for the last number, 750, specifically since it is too different -- has a number 5 in the middle. If we include 5 in the middle regex range, it will go up to 759, which is outside of the scope.\r\n\r\nFinally, **OR** both parts and the regex is ready.\r\n\r\nAdjust for your input. You may need to surround it with ^ and $ for the beginning and the end of the line or if your input has other text surrounding the number in question, expand your regex to deal with it appropriately.","772"],["Your JSON is not valid.\r\n\r\nIssues:\r\n\r\n - `None` should become `null`\r\n - `True` should become `true`\r\n - `False` should become `false`\r\n - URLs cannot have double-quotes within them.

For example, ./foo/thumbs/thumbs/ will not work because `mv` will take care of ./foo/thumbs first and make it ./foo/thumb, but then the next output line will result in an error because ./foo/thumbs/thumbs/ no longer exist.\\r\\n\\r\\n**Goal 2:** To change **all** subfolders \\\" ;thumbs \\\" ; to \\\" ;thumb \\\" ; regardless of how deep.\\r\\n\\r\\n**Example Input:**\\r\\n \\r\\n ./foo1/thumbs\\r\\n ./foo2/thumbs\\r\\n ./foo2/thumbs/thumbs\\r\\n ./foo2/thumbs\\r\\n\\r\\n**Solution:**\\r\\n\\r\\n find . -type d | awk -F'/' '{print NF, $0}' | sort -k 1 -n -r | awk '{print $2}' | sed 'p;s/\\\\(.*\\\\)thumbs/\\\\1thumb/' | xargs -n2 mv\\r\\n\\r\\n**Output:**\\r\\n\\r\\n ./foo1/thumb\\r\\n ./foo2/thumb\\r\\n ./foo2/thumb/thumb\\r\\n ./foo2/thumb\\r\\n\\r\\n**Explanation:**\\r\\n\\r\\nUse `find` to give you all \\\" ;thumbs \\\" ; subfolders. Pipe the output to `awk` to print the number of '/'s in each path plus the original output. `sort` the output numerically, in reverse (to put the deepest paths on top) by the number of '/'s. Pipe the sorted list to `awk` to remove the counts from each line. Pipe the output to `sed`. The `p` option prints the input line and the rest of the `sed` command finds the **last** occurrence of \\\" ;thumbs \\\" ; and changes only it to \\\" ;thumb \\\" ;. Since we are working with sorted list in the order of deepest to shallowest level, this will provide `mv` with the right commands. Finally, pipe to `xargs`.

This captures all numbers from 150 to 199.\\r\\n\\r\\nThe last number in the first range is 200, so we can just look for that. It is too different from the rest of the possibilities in the range, thus it is easier to look for specifically for it instead of trying to think of a complex way of including it in a regex range.\\r\\n\\r\\nThe second range follows the same patten but with different numbers. Again, we are looking for most of the numbers by using the regex range and looking for the last number, 750, specifically since it is too different -- has a number 5 in the middle. If we include 5 in the middle regex range, it will go up to 759, which is outside of the scope.\\r\\n\\r\\nFinally, **OR** both parts and the regex is ready.\\r\\n\\r\\nAdjust for your input. You may need to surround it with ^ and $ for the beginning and the end of the line or if your input has other text surrounding the number in question, expand your regex to deal with it appropriately.\",\n \"772\"\n ],\n [\n \"Your JSON is not valid.\\r\\n\\r\\nIssues:\\r\\n\\r\\n - `None` should become `null`\\r\\n - `True` should become `true`\\r\\n - `False` should become `false`\\r\\n - URLs cannot have double-quotes within them.

I added my own custom commands to modify the `line-height` in paragraphs.\\r\\n\\r\\nThe CSS sets a default font size and line height for the editor:\\r\\n\\r\\n div {\\r\\n font-size: 20px;\\r\\n line-spacing: 1.25;\\r\\n }\\r\\n\\r\\nThe initial markup is something like this:\\r\\n\\r\\n < div > \\r\\n < p > Some long text that wraps here... < /p > \\r\\n < p > Some long text that wraps here... < /p > \\r\\n < p > Some long text that wraps here... < /p > \\r\\n < /div > \\r\\n\\r\\nAfter setting the font size and line height with the editor, the markup becomes:\\r\\n\\r\\n < div > \\r\\n < p style= \\\" ;line-height: 1; \\\" ; > < span > Some long text that wraps here... < /span > < /p > \\r\\n < p style= \\\" ;line-height: 1; \\\" ; > < span style= \\\" ;font-size: 8px; \\\" ; > Some long text that wraps here... < /span > < /p > \\r\\n < p style= \\\" ;line-height: 1; \\\" ; > < span style= \\\" ;font-size: 40px; \\\" ; > Some long text that wraps here... < /span > < /p > \\r\\n < /div > \\r\\n\\r\\nAs long as the font size in the `span` is equal or larger than the font size of the paragraph (in the present case, `20px`), the line height scales correctly. However, when the font size in the `span` is smaller than that of its paragraph, the line height does not scale as it should. The problem can be seen in **[this jsfiddle][2]**.\\r\\n\\r\\nIf I set `display: inline-block` on the `span` elements, the line height scales properly but that display setting messes up the wrapping in the editor.
