Every time I start up this windows XP laptop (lenovo t60), the svchost and wuauclt processes take up ~200,000k memory each. in addition, svchost takes ~50% of cpu power.  Is there any way to alleviate this?  this happens every time. I can end both processes but that has caused problems with wifi connection.
I'm running Windows 7. It seems that svchost is eating up a lot of memory.   The user name for the particular svchost instance is "Network Service". The description is "Host Process for Windows Services".   Sometimes it eats up 50% of the CPU usage. Other times, it's just under 5%. I can't figure out when it's 50% and when it's not. But it fluctuates often -- even when I've just booted up and no programs were started.  How do I diagnose this?
What does "...from nonmagical attacks not made with silvered weapons" mean? I'm sure your first thought is, that's perfectly clear.  Unfortunately my group who aren't normally rules lawyers disagree.  Party encounters a  (MM p.211).  It has:     Damage Immunities: bludgeoning, piercing, and slashing from nonmagical   attacks not made with silvered weapons.   My reading of that is if the weapon has to be magical and silvered to hurt it.  So a +1 silver dagger will hurt it, but a +1 regular dagger or a +0 silver dagger won't.  The group's interpretation was that all three of those weapons would hurt and only a +0 regular dagger would be ineffective.    I would also note my interpretation would mean something like blade barrier would also not harm it since you could argue they're magical blades but nothing indicates that they're silvered.    This also appears to be the same wording for some undead so I'm not looking for a lycanthrope specific interpretation but something general for every time that wording is used.    Thanks in advance. QGIS corrupting shapefiles? I'm hoping someone out there might be able to help or suggest some tests to try and resolve some very odd QGIS behaviour of late...  Our core GIS team of 4 users has been testing v2.10 prior to roll-out for the remainder of the organization.  In the past couple of weeks we have had some very odd shapefile corruption things happening and are yet to isolate or identify a potential cause...  These have included:   Editing one line (using the scissor tool to split into two records) and having the resulting records attributes completely replaced by attributes from another geometry no-where near the edited row (spatially or in the attribute dbf) Line geometries completely disappear while their attributes get associated with an unrelated geometry  Line geometry get partially deleted and replaced with a vertice in infinity (line visually extends beyond the dataset and no matter how far zoomed out you never see the end)   The above is happening in a polyline layer, that we did discover has some multi-line geometries..? Perhaps this is impacting... but never saw this issue with v2.8 and the same layer. The layer has undergone MANY save-as's in the past week and many verify geometry checks as we thought invalid geometry may have been the cause...  In another separate layer yesterday, to a separate user (me) i created a layer with approx 30 polygons... adding, deleting some and doing some 'avoid intersection' to remove overlaps. Layer looks fine in qgis, saved and also a save-as to a completely new file but when i load into ArcGIS online (and later is ArcMap as a test) some of the overlaps and deleted objects are still there. Close and reopen qgis,  reopen the file and they are definitely not.  The project was created in v2.8 that i was editing in (but had been saved in 2.10).  Does anyone have any ideas/suggestions.  We do still have 2.8 installed as well as 2.10? We have never encountered issues like this when testing other new qgis versions while still running old ones? extracting energy from cosmological expansion This question is a more concrete reincarnation of an .  Are there mechanisms to extract energy from the cosmic rate of expansion? putting some extremely long ropes across the universe and extract work from their increase of separation?  assuming this is possible ( i don't see why it would not ), what form would take the back-reaction force? in all physics, every time you extract work from some system by some force, this system will exert a force back. Can we slow down cosmic expansion by variations of these mechanisms? When do moderator elections take place? I'm really confused on this. I have no idea on several things:   When do elections begin?   Is there a set time each year?   Do elections actually take place each year?   Can I vote?   Where do I vote?     Etc.  Can someone please help me? I see ads to other SE sites regularly on the sidebar of SO. Are these questions chosen by hand, or algorithmically? The reason I ask is that there was an ad pointing to  on Seasoned Advice. I'm all for a good laugh I suppose, but is this the kind of question that should be highlighted?  It's obviously a thriving community, but if this were my first exposure to that community, and I saw that the highest-rated answer -- from the user with the highest reputation -- was (and I paraphrase only lightly):  &quot;Why yes, there is tool that can cut cherry tomatoes in half.  It's fantastic for the job.  It's called a freakin' KNIFE!&quot;  would I ever want to visit again, let alone ask a question over there? First impressions count for a lot, and that one missed the mark IMHO. If the selection method is algorithmic, I suppose there's no reliable way to detect sarcasm in a highly-rated answer, but if it's manual, weeeellllllllll ... :) Can I ignore coefficients for non-significant levels of factors in a linear model? After seeking clarification about linear model coefficients  I have a follow up question concerning non-signficant (high p value) for coefficients of factor levels.  Example: If my linear model includes a factor with 10 levels, and only 3 of those levels have significant p values associated with them, when using the model to predict Y can I choose to not include the coefficient term if the subject falls in one of the non-signficant level?  More drastically, would it be wrong to lump the 7 non-significant levels into one level and re-analyze? Which offences result in indirect free kicks? If a player commits a direct free kick offence in their own penalty area, this results in a penalty kick instead of a direct free kick. However, if the offence is an indirect free kick offence, it remains as an indirect free kick .  What offences result in an indirect free kick? I use \includegraphics command to insert image to the document. But how can I add a border around this image w/o any margin between border lines and image? It seems to be very easy, but I can't find it in the documentation. A graph $G$ is bipartite if and only if $G$ can be coloured with 2 colours Why do I have to click twice to submit a question when Stack Exchange's automated question review has no advice to show? This is terrible . I understand that the motivation behind "Review your question" is quality control, but if there is nothing for me to review, why can't the question be submitted in a single click?  Instead the page jumps back, to draw my attention to possibly this:    But it doesn't stand out in the UI, and if you didn't read that the button said "Review your question", it's hard to see why the page just jarringly jumped back instead of posting the question.  Is it really important for me to know that the automated system didn't find any way to improve my question?  Does Stack&nbsp;Exchange have metrics to see how often the question passes the quality check in the first go?  To add a minor point, as a veteran Stack&nbsp;Exchange user, the system doesn't have any reviews most of the time (in fact, the only time it had one is today while posting this question where it reminded me that one of feature-request, bug, .. tags were required). Using Fermats prime numbers to prove that there is infinitely many prime numbers How can I distribute a native executable for a Python program? Suppose $p$ is a prime number such that $(p-1)/4$ and $(p+1)/2$ are also primes. Show that $p=13$ Suppose $p$ is a prime number such that $(p-1)/4$ and $(p+1)/2$ are also primes. Show that $p=13$.   My approach:   Since $p$ is prime, it is of the form $6k+1$ or $6k-1$. Now if $p$ is of the form $6k-1$ then $(p+1)/2 = 3k$ which is not possible as $3|3k$.   So $p$ is of the form $6k+1$. Now $(p-1)/4 = 3k/2$ so $2\mid k$. So $p$ is of the form $12k+1$. But now, how to prove $k=1$?  Please help! Multiple "order by" in LINQ JUnit @Test expected annotation not working What can primes, except 2, 3, and 5, be congruent to $\pmod {30}$? After some trials, I found out that a prime $p \gt 5$ is congruent to $q\pmod{30}$, where $q$ is also a prime, and $1 \le q \lt 30 \;$ (i.e.  $p \equiv q\pmod{30}.$  Is there a way to write a formal proof to show this?  Is that an acceptable answer. I have a problem with this limit, I don't know what method to use. I have no idea how to compute it. Is it possible to compute this limit with the McLaurin expansion? Can you explain the method and the steps used? Thanks. (I prefer to avoid to use L'Hospital's rule.)  $$\lim _{x\to 0}\frac{x\bigl(\sqrt{3e^x+e^{3x^2}}-2\bigr)}{4-(\cos x+1)^2}$$ Is "do something by date X" inclusive? Sorry if this is the wrong place to ask this, I'm new to the site :/  My issue is this: when editing in vim, my syntax file highlights underscores and carets when found in non-math text, which is fine, except vim doesn't recognize that "align" is a math environment. What do I need to do to fix this? Is the use of a hyphen between "non" and an adjective strictly necessary? Do I need to put a "-" between "non" and an adjective? As an example in physics we say "a non isolated photon", "non tight photon"... The context is very formal (paper publications and similar). Is there a general rule? Are there some differences between countries?
