I don't have administrator account anymore - macOS 10.13.4 I tried the answers on the similar previous question but nothing worked. Obviously Apple removed the critical file .AppleSetupDone in the last Security Update. Is there anybody who could help getting my administrator account back?
I don't have administrator account on my mac On my mac I have 2 accounts and the both are normal account. So in this moment I don't have a Administrator account, only one that was in the past a administrator, but now is not.  How I can have again a Administrator account?
I understand if you travelling in or to the US, you can lock your luggage using the TSA Luggage Lock. (Immigration is still able to open your luggage using their own special keys)  How about Europe? Especially Heathrow + Charles de Gaulle?    If the TSA Lock is not acceptable in Europe, are there any other alternative precautions I could use instead?  (FYI, information about the ) Looking for a 1000 most frequent english words Is there a free list of 1000 most frequent words used in everyday English? If there is a list with usage examples (as each of those words has multiple meanings for sure, not to cound phrasal verbs), it would be even greater.  Is there something alike, but with phrases? (E.g. 1000 most frequent phrases) What does this pen notation in my UK entry stamp mean? I entered the UK from Paris once (riding the Eurostar train), and after the UK border control officer placed an entry stamp in my passport, he added a notation in pen (picture below).  What does it mean?  I suspect it is some sort of "warning" (the border control officer was not happy with me, though thankfully did not refuse entry).  I've always been curious about what it means more precisely or whether my prediction is even correct.  I've entered the UK only once again after getting this stamp.  I was admitted then too, but it took a while (the border control officer went away for about 10 minutes to do something before letting me in). When did the word "so" begin to be used to start a sentence? In the last few years, I've noticed a growing usage of the word "so" to begin a sentence, especially in the context of higher education.  For example:   Interviewer: "What is the nature of your research"  Researcher: "So, what we wanted to find out is..."  It seems to be a replacement the word "well", or, more informally, "ok".  Has this usage of the word been around for a long time and I'm just now noticing it?  Do you think that is a valid use of the word? Usage of dash (-) in place of a filename For a command, if using - as an argument in place of a file name will mean STDIN or STDOUT.   But in this example, it creates a file with the name -:  echo hello &gt; -   How can I make - in this example mean STDOUT? Conversely, how can I make - mean a file named - in examples such as:  cat - Currently my bibliography says "Literatur" (german). But I want something completely different there. How can I achieve that? Apache: Scammers point dozens of domain names at my dedicated IP. How to prevent this? For the sake of discussion, pretend that I have an Apache webserver which serves a website at www.example.org. This domain name resolves to the public IP address at 192.168.1.100 (pretend this is a public IP).  The discussion at  demonstrates that anyone can point their domain at my IP. Apache won't prevent this by default, but an administrator can deal with these one at a time through use of a blacklist.  However, it's becoming more common for scammers to register dozens of domains (or more) for use in a scam. I'm concerned about the following possible attack:   A scammer registers hundreds of domain names, and points them at my dedicated IP address. The scammer directs search engines at their scam domains, thus using my content to increase their standing in the search engines. Later, the scammer moves their domain names to point to their own servers which host a scam/porn, or a competing business, etc. thereby reaping the benefits of their standing in the search engines. Some of these domains might be used to in  as well. Profit!!   I believe I have seen scammers using this trick in the past, involving dozens of domains. We didn't realize the scam implications at the time, and assumed these were misconfigured domains.  Is there a term for this nefarious SEO trick? SEO masquerading? DNS Diversion?  How could I prevent this using Apache? I'm considering a "whitelist" fix based on using a default VirtualHosts, ServerNames &amp; ServerAliases so that Apache only responds to requests where these white-listed ServerNames appear in the "Host: " header. Everything else would be rejected (or redirected to a particular page). However, I am unsure if this is the best approach.  For example, I've configured the domain  to point at the IP for Serverfault.com. You can see the results here:  . A finite sum involving the binomial coefficients and the harmonic numbers Karn, the Great Creator - what defines a 'card from outside the game' in sealed? In the upcoming set 'War of the Spark' there is the Planeswalker . His -2 ability reads as:      -2: You may choose an artifact card you own from outside the game or in exile, reveal that card and add it to your hand    Now my question is, in a sealed tournament, like the Prerelease, is a player allowed to also choose cards from outside his sealed cardpool, or only out of the cards therein. Does anyone know any rulings on stuff like that? How do we show that equality holds in the triangle inequality $|a+b|=|a|+|b|$ iff both numbers are positive, both are negative or one is zero? I already showed that equality holds when one of the three conditions happens. Does Earth really have two high-tide bulges on opposite sides? The bit that makes sense – tidal forces My physics teacher explained that most tidal effect is caused by the Moon rotating around the Earth, and some also by the Sun. They said that in the Earth and Moon system, the bodies are in freefall about each other. But that points on the surface of Earth, not being at Earth's centre of gravity, experience a slightly different pulls towards the Moon. The pull is a little greater if they are on the Moon's side, and slightly lesser if they are on the side away from the Moon. Once freefall is removed, on the Moon side this feels like a pull towards the Moon and on the the opposite side it feels like a repulsion from the Moon. This makes sense to me, and is backed up by other questions and answers here, like  and also  Phys.SE question. The bit that doesn't make sense – tidal bulges They also said that there are &quot;tidal bulges&quot; on opposite sides of the Earth caused by these forces. The bulges stay still relative to the Moon and Earth rotating through the bulges explains why we get two tides a day. They drew a picture like this one…  An image search for  finds hundreds of similar examples, and  from a scientist on Twitter. …But, if there is a tidal bulge on both sides of Earth, like a big wave with two peaks going round and around, how can an island, like Great Britain where I live, simultaneously have a high tide on one side and a low tide on the other? For example:   on the West coast  on the East  Two ports with tides 6 hours, or 180º apart. It's high tide at one while low tide at the other. But they are only  by road. Great Britain is much smaller than Earth. It's probably not even as big as the letter &quot;A&quot; in the word &quot;TIDAL&quot; in that picture.  To prove this isn't just Britain being a crazy anomaly, here is another example from New Zealand:     Two ports that are 180º (6 hours) apart, but separated by  through a national park. New Zealand, unlike the UK, is in fairly open ocean.

Thanks What physical properties of materials trigger the capacitive touch screen? I have watched some youtube videos about capacitive touch screen      The videos show that a conductor(finger), in which charges can be induced, can be used to trigger the capacitive touch screen. However, I tried to wear a plastic glove to hold a metal rod to touch the screen and no detection is triggered.  I really want to know the physics theory about the capacitive sensing.  Can someone tell me what physical properties or shape trigger the capacitive touch screen?  Is there any examples that something WITHOUT conducting to human body can trigger the screen?  (P.S. I have read other posts about capacitive touch screen here and do not find a good answer so this is not a duplicate) Can I use mirroring to make a copy of my Database? I was browsing flight price at Singapore Airlines website, and a one-way flight from SIN to SFO cost this much:    That's quite expensive. I tried browsing around and found that a return flight from SFO to SIN and back to SFO cost much cheaper:    It's really weird because the second ticket includes the exact same flight that cost 1900+, but it's almost half the price. The reason for this counter-intuitive situation is explained in the answers this question   If I am located in Singapore and my intention is to fly one-way to SFO, is it safe to book the flight in the second picture and only board SFO-SIN leg? Will they deny me because I miss the SIN-SFO flight? Two seasonal periods in ARIMA using R I'm currently using R to predict a time series with these instructions:  X &lt;- ts(datas, frequency=24) X.arima &lt;- Arima(X, order=c(2,1,0), seasonal=c(1,1,1)) pred &lt;- predict(X.arima, n.ahead=24) plot.ts(pred$pred)   As you can see I've data each hour, and I chose the seasonal period of 24 (one day).  I would like to improve my forecasting using an additional seasonal period in order to include the seasonal component of the week (seasonal length of 7*24=168 data)  Is there any method for this? How do you do it?  UPDATE: I've read  (your) blog page, maybe can I use the external regressors to simulate a second seasonal period? Does a surjective ring homomorphism have to be surjective on the unit groups? I would like to see a breakdown of reputation by post type on the user summary page.
