Machine Needs F1 Key to Reboot, How to Skip This?
This has nothing to do with the operating system. It's a BIOS thing.You need to enter BIOS just when you power up the computer with one of the following keys:DEL F2 F9 F10 F11 F12 depends on BIOS type, you should be shown the key that enters Setup during POSTThen go into the basic settings and change the setting for keyboard errorsâ¢ Related QuestionsTerminal has no option to open new tab and no label in tabsEncounter the same issue after upgrade from 14.04 to 16.04. It took me sometime to find the "preference" window as the solution mentioned above in Ubuntu 16.04. In case some other people have the same issue, I share the way to find the preference window.You can find the preferences by: open a terminal, at the terminal right top are the hidden tabs -> terminal ->Preferences------how to simulate FX forwardsIf I understand correctly, you want to calculate the present value of some FX Forward contracts. The only part of the value I can see which could require any MC would be looking at the XVA components, which is much less about the forward and much more about the counterparty & collateralisation.If you just want to value some vanilla FX Forwards, don't do MC.------character and camera not moving in the same speedMaybe it is a point of view opinion but it seems you should use another approach : Good tools for that is :Making your cam position relative to a transform :this should already make your code easyer to maintain and it could allow you to switch between targets painlesslyEDIT:And to stress it even more as Byte56 stated : Get rid of all the useless stuff------Call fieldset multiple timesFor anyone else that stumbles on this. I found a solution. So remember my example is "How Many Players" i used select option 1-5. If user selects 1, fieldset 1 appears only, if he/she selects 2, FS1 and FS2 appear, select 3, FS1, FS2 and FS3 appear. To prevent the error I use and or statement for allow the fieldset and worked my down down. See image.------How to find the components of a perpendicular vectorYou have $$-n_13n_20$$ $$n_1-5n_22n_30$$Choose one of the three variables freely (but not zero) and solve the remaining system.It can happen that the remaining system does not have a unique solution (not the case here, no matter which variable you choose).Bue even this is no problem because in this case you can choose a second variable freely (even $0$).------How to get a data attribute inside an option of lightning:select componentYou can't get to it, at least not the way your code is written. Regardless, this still seems a lot more complicated than it should be. Here's a more practical version:Here, we just get the list back out, find the record we want, and, if one was selected (as opposed to none), we now have all the information we need from the record.------Shower stall kit around $300 but isnt made of cheap components?All shower kits are made of cheap materials that is why you find them in low end houses. Your best bet and it would cost no more than $300 is ceramic tile. It's actually easier to install than a surround especially in older houses where the walls aren't plumb. Do a little web research and ask some questions on how to do it------What is the purpose of a microcontroller bootloader? duplicateJust to also give a hobbyist's perspective:It makes life much easier in not requiring any additional hardware or much low-level knowledge. One extreme example I used was the particle photon (no affiliation) which can get flashed over the cloud. The only things required to flash this chip are:It makes the process rather inexpensive and is actually quite simple from a non-pro perspective.------Looking for a 1 to 1.5 mm pitch board to wire connector that locksYour best bet is to do a parametric search on one of the large suppliers sites. Here is an example search on Farnell that returns 2000 results for wire to board between 1mm and 1.5mm. You can narrow it down as necessary (e.g. contact number, orientation, etc)When you find a suitable part you can search for it elsewhere by product number if necessary.------Receive raspberry stream in C#It seems like you have already nailed the RPi part of the issue, and is only missing the windows component.As with your netcat setup, you need to create a listening socket in C#: suggest you try to ask for implementation details on stackoverflow, as this problem is highly relevant there and you will get some really good answers.------Export and import content from one drupal site to another?The Migrate module can migrate anything you want from the most databases.Depending on how your content is put together this might be relevant for you.Links:Also be sure to look into the Migrate module folder. It contains a Beer.inc file, which is an example of how you can do simple mappings. For more complicated migrations you can look into Wine.inc------PageObjects: Aggregation/Composition vs Inheritance for nested componentsI'm using the inherited based design. It worked great until the application I'm testing was also made available in another, more limited customer-facing UI. So now I have two applications which consist of the same components surrounded by different menus. That's a situation where the inherited design breaks.An aggregation-based design combined with some IOC container could be a lot more flexible, I guess------How to solve vector equations?The question has part of in application of calculus in physics. Ypu need to verify $curl vec F 0$ to determine if there exists $phi$ such that $F nabla phi$. $phi$ is called potential in physicsOnce you confirm there exisrs a $phi$, you can try to integrate partially and combine three to get $phi$I believe $curl vec F ne 0$, so there is no potential.------Expressing position due to gravitational acceleration as a 3-Dimensional differential equationThe easiest thing to do is to start from the gravitational potential$$phi-fracGm_1m_2sqrtx^2y^2z^2$$and use $vec F-vecnabla phi$, or in components:$$F_x-fracpartial phipartial x-fracGm_1m_2,x(x^2y^2z^2)^3/2 m_2 A_x m_2 fracd^2 xdt^2$$with a similar approach for your other components.------syllogism package new counterThere's no need to use a new counter (would be difficult, perhaps)I used another approach, replacing the list in @sylloc command with a special sylloglist which is a clone of enumerate, which provides the counter anyway.The 3rd item is a rule, I have to replace item ... with item there.The list spacing settings have been incorporated into the optional argument of sylloglist.------How to change the html of threaded comments?Could you give a little more info on what you are trying to do?If you want to add your view for displaying comments to a specific thread, please take a look at using panel from contrib ( module allows you to add views (and other components as well) to specific pages, other panels (when using mini panels) etc------Slope of tangent in $(x,y)$ on a circle $K(x,y)inmathbbR^2|x^2y^2r^2$ with initial conditions$r$ is indeed constant (otherwise $K$ wouldn't be a circle)It doesn't matter if separate constants of integration are included on both sides. (Two arbitrary constants can simply be combined: $c_1 c_2$ is still just a constant).$c2$ and $c5$ come from the initial values: $y(1) 1$ and $y(-1) 2$, respectively. In the first case $x1$, $y1$ which gives $c2$. Similarly for the second case------Would a triangle wave have finite or infinite sinusoidal components?a triangle wave is continuousQuote from here: -The triangle wave has no discontinuous jumps, but the slope changes discontinuously twice per cycleHaving the slope change discontinuously also means an infinite range of sinusoidal components.For instance, if you time integrated a square wave you produce a triangle wave but, all the hamonics of the original square wave are still present after the time integration: -------How do I explain to a team that the project they will work on for six months will certainly be cancelled?If the company is making a mark-up of 200%, one way to motivate your developers is to offer them some of that, surely? Say, an extra month's pay on acceptance of the sham product if (as expected) it gets cancelled after six months. You could even give them the option not to participate in the work, but I doubt that there would be many takers------Decomposing quasi-finite separated group schemesAt OP's suggestion, I am moving my comment to an answer. In the original question $U$ was the spectrum of a Henselian DVR $R$ with $K mathrmFrac(R)$.Define $G_1$ to be the union of those connected components of $G$ whose images cover $U$. Then use EGA $textIV_4$, 18.5.11 c) to verify that $G_1$ is a clopen $U$-finite subgroup scheme of $G$------How are files opened in unix?Generally you should read a book like this one to get answers for most such details inside kernel. But, in general, yes, the process is that:Details of directory search for this are very specific for particular VFS. It can be of any kind including memory-only ones (tmpfs), disk-based ones (ext4, etc.), but the common concept of hierarchy of directories is kept in effect------How to make the HT12E transmit (TE to low) only when one or both buttons are pressed?It may be easier than you think; if you look at the data sheet more closely: -So, any button being activated will automatically pull TE low and enable transmission and, in the case when buttons are released (thus deactivating TE), this diagram tells you that the device will continue to transmit the four byte message and thus inform the receiver that buttons are deactivated: -------how to post data of a form to an iframe in lightning component?The browser's same-origin policy prevents a page from accessing content or code in another page loaded from a different origin (protocol port host).You can use postMessage() to communicate between your Lightning Component and the content of the iframe. See this blog post for details.In Spring17, you can also use the Lightning Container Component, but be aware that it is in Developer Preview.------Need sorting method for coordinated, flattenned collection closedThis is not just a sorting problem. You are also updating the YOffset values based on the sorting. So assume the input data is valid(i.e. no missing offsets, consistent type of Value property). Here is the code:Source data:LINQ:Verify the result:The output:Note: I kept sortedByFirstColumn as IEnumerable and unordered, but adjust it the way how your application requires.------Defining real powor of linear operatorThis is impossible. Consider $Vmathbb R$ and $Tx-x$. A linear $T^frac 1 2$ would satisfy $T^frac 1 2T^frac 1 2 x -x$. All linear operators on $mathbb R$ are of the form $Ax cx$ for some $cinmathbb R$. Thus, assuming $T^frac 1 2 x cx$, we get $c^2 x-x$. For $x1$ this gives $c^2-1$ which has no solution in $mathbb R$------Why does water reflect light?EM wave consists of electric and magnetic component. Electric field is responsible for reflection. When EM wave hits the water surface electric component turn molecules of water (H2O is a dipole) Next moment water molecules want to go back in initial position. So they turn back and thus so many molecules at the same time re-emit new EM wave in the opposite direction------Basic tension and equilibrium confusionThe object is not in equilibrium. However, you can still calculate $F$. You know that the string isn't lengthening or shortening, so the net force in the direction of the string is zero.So you can decompose the three forces in the problem into components along the string and components perpendicular to the string, and set the net force along the string to zero------Is there any scrappable junk I should hold on to that could otherwise be used for other purposes?Over due library books can be returned at a library in exchange for book return tokens, you can trade in the tokens for misc items like a camera or toys, and if you have enough you can get a Surgical Magazine.I haven't figured out if subway tokens have anything similar yet so for the time being I've just been holding on to them------Find the coordinates for $v$ in the subspace $W$ spanned by the following vectors:Basically what @PrahLad said, $v a_1u_1 a_2u_2 a_3u_3$ So since $u_1,u_2,u_3$ are orthogonal you can use the formula $a fracy cdot uu cdot u$ or in your case: $alpha fracv cdot u_iu_icdot u_i$So the first one for example will be $fracv cdot u_1u_1 cdot u_1 $ (your calculation here)------What is the purpose of marking the positive terminal of an 50% duty cycle oscillating source?It is just common practice. In reality there is no need, but people like reference points, and things that feel familiar to them. People who have a lot of experience with electronics know that there is almost always a positive and a negative end (even if it is arbitrary and does not matter). Putting a is just a way to make people feel comfortable.
