I found a MacBook Pro stranded in a train. How can I wipe all the data and use it? Not able to trace the owner. The laptop is password locked.
Last Thursday my wife put her 217 MBP on the school fence as she was looking for her car keys and forgot it there (after a long 12 hours work + school day). As we returned later it was obviously not there anymore someone found it and took it. I did everything possible from going to the police to ads on social media and buy&sell sites (offering a substantial reward) contacted all pawn shops repair centers and of course Apple support. $3 worth of hardware plus at least $1 in software applications were just gone not to mention 4 or 5 months worth of data. The find my Mac feature was of course active but it only worth something when and if theputer gets connected to the Internet. The laptop was all the time shown as being offline. Apple support was of no use. They kept telling me to go and file a case with the police and that they cannot help with this although it is technically possible to trace a laptop even in case it has beenpletely wiped. Not to mention having to ask for another call center agent as the first one waspletely unable to understand me; he could barely speak English. Long story short on Monday someone called us saying he found the laptop and saw our ad with the contact number so we could meet to get it back. We went took it back (it was untouched) offered a quite generous reward and everyone is happy again. However most of the lost devices are not going back to their rightful owners. Even if a finder is unable to crack the password or install it as new a lot of them just sell the devices for spare parts as the display or battery instead of trying to locate the owner. What really blows my mind is the amount of user answers providing advice on how to reset the password to make the laptop usable. To those lacking any sort of morality or legal knowledge please just stop! You are basically helping out a thief! Yes keeping a found item is legally considered theft and to the original poster of the question claiming to not being able to trace the owner is utter crap. You should turn it to the nearest police station or lost & found office at the train station so the owner can get it back as Im sure these are places where anyone would go first. Doing nothing of this just means your intention was always to keep the device. Later edit Thank you all for the upvotes I saw some peopleing this wasn an answer but a personal story with a theft accusation on top of it. Let me ex. First of all I wouldn provide any help to someone who simply asks how to erase all data from aputer he found so he can use it for himself. Never implied that the original poster actually stole the laptop however the phrasing of the question suggests little to no effort has been made to find the rightful owner it just something along the lines of ok found a Mac how can I make it mine? This is not acceptable where Ie from. Also the story of my wife Mac was just an example of a case where the finder did the right thing. Yes people are fully responsible for leaving valuable devices behind but this doesn mean that those who find them are entitled to keep them in no way shape or form. At least not until every effort is made to find the owner.
How do I fix a locked laptop?
The quickest and easiest way to clear the password is to call the laptoppany makers and get them to fix it the other way is just a little more technical this looks like just a user password configured to not let the system boot without the correct password instead of a supervisor password so first we are going to turn off theputer take out the battery on most HP batteries there will be a switch on the back pull it right until it pops out. do this after theputer is fully off! not plugged in at all even the slightest shock which is like a pinch to you is just like a bullet into your head to yourputer its also advised to use a anti static wrist band when inside theputer now once this is done keep theputer over see if you see any holes at all which would allow for easy clearing of the CMOS if so get a paper clip straighten it out then now press down on the hole with it for about five seconds then it should be cleared if not your setup might be different HPputers batteries reside on the top for easy access hear is a picture not all batteries look like this next is a little moreplicated if you don have the ability to clear the CMOS with a paper clip open up theputer by taking a capable screw driver and screwing the screws out of the bottom of your case then there should be a little battery inside that looks like this take it out it varies onputers google it or whatever search engine you use then wait for a couple of seconds place it back in screw back theputer and the password should be bypassed or as others have stated use a hard drive backup if you didn't back up your data there is no reinstalling windows you can do its a BIOS password meaning you can boot without that password move the hard drive to a newputer if you have a backup actually now that i think about it the BIOS is stored on a separate chip other than the hard drive so move the hard drive to a newputer the best option to do is if you still have access to that email send yourself a reset for the password to the BIOS then login it do not reinstall Windows its none thing to do with reinstalling Windows this is not a Windows lock it happens at boot up you or the owner like a administrator set a Boot password instead of just a supervisor password there are a couple of more options but i will let the experts handle it from hear!
As an ML engineer at Quora, have you ever implemented a research article in machine learning to solve a technical or product problem?
I joined Quora as a machine learning engineer earlier last year and have been working on how to automatically correct errors in questions. I found inspiration in a paper published by Ziang Xie ( Ziang Xie et al. 216 italic s ) which showcases an end-to-end neural language correction model. At Quora we get tons of questions every day by people from different countries and backgrounds. We want to enable everyone to ask any of question they want regardless of their English proficiency without having to worry about syntax and semantic errors. As such we built a machine learning model that can automatically correct manymon errors in questions including spelling mistakes missing prepositions wrong punctuation wrong capitalization etc. Here is a representative example The difficulties in question correction are perfectly demonstrated by this example. First this question starts with Hello sir which is unnecessary. Second it has an unnecessary space between the words achievement and period. Finally to be grammatically correct the is required before the abbreviation SSB.n nIn general language correction is one of the mostplex problems in the field of natural language processing NLP. The ~nlp CoNLL-214 conference italic ~nlp has apetition focused on this general challenge. Thepetition has attracted lots of researchers to solving the problem. horizontal-rule Problem definition The question correction problem can be defined as follows Given an error-ridden input question x map it to an output question y with errors in x being fully (or partially) fixed.n nMost of the existing research in this area focuses on training classifiers for specific s of errors. For example Han ( Han et al. 26 italic ) trained a classifier to correct article errors and Rozovskaya ( Rozovskaya et. al. 21 italic ) proposed a system focused on correcting preposition and determiner errors. However training separate models for different error s is inefficient and it would be preferable to correct all errors in one model if possible. Towards this goal Ziang Xie's recent paper italic s caught my eye as a potential solution. Main architecture The coreponent of Ziang Xie's s paper italic s is an encoder-decoder recurrent neural network RNN with an attention mechanism (as shown in Fig 1). It operates at the character-level so that 1) the out-of-vocabulary OOV problem can be avoided and 2) it has the ability to fix spelling errors. However by operating at the character level the total sequence length is largepared with operating at the word level which means the time required to encode a question is high. On the other hand the search time for the decoder is reduced as the vocabulary size for the character level is much smaller than the word level. Figure 1 the encoder-decoder architecture. The encoder network uses a bidirectional gated recurrent unit GRU ( Cho et al. 214 italic s ). The main architecture of a GRU is very similar to that of a LSTM. It has two gates a reset gate and an update gate. The reset gate determines how tobine the new input with previous information (also called memory) whereas the update gate defines how much of the previous memory should be preserved.n nThe entire encoder network contains three layers to map the input question x to a high-level representation. Except for the first layer which uses character ding of the input question x as the input each layer concatenates its forward and backward hidden states the result of which is used as the input for the next layer (as shown in Fig 2). Figure 2 the first layer in the encoder network. The decoder network uses a standard GRU and each GRU unit can only get information from past unit but not from the future. It also has three layers and the last layer is conditioned on the encoded representation using an attention mechanism ( Bahdanau et al. 214 italic s ) which is a weighted sum over the hidden states in the last layer of the encoder. With this attention mechanism we can ensure output question y won't diverge from input question x. In other word we want to make sure that question y retains the meaning of question x. The optimal output sequence is retrieved using beam search italic s with a pre-defined beam . Beam search is a greedy algorithm. It uses breadth-first-search with a limited number of nodes (so called beam ) maintained at each level of the tree. In general larger beam size will lead to more accurate results but with longer search time and more memory usage. In our case the beam is set to 8 which shows a good balance between speed and accuracy.n nCurrently we use this model to correct new questions and the accuracy of the model is measured using s BLEU score italic s . The BLEU score ismonly used to measure the quality of a machine translation system. Specifically it measures N-gram overlap between machine translation output and reference (ground truth). Figure 3 an example ofputing 4-gram BLEU score between machine translation output and reference . To better suit our needs we modified the original architecture a little bit by reducing the number of layers used in the encoder and the decoder from three to two. After experimenting with a few differentbinations we found that this gives us the optimal trade off between inference time and accuracy; i.e. we achieved much faster prediction time but not much worse accuracy. Figure 4 an example of questions auto-fixed by our question correction model. Green added part; Red deleted part. horizontal-rule At Quora machine learning has been used in many different ways such as answer ranking duplicate question detection spam detection etc. To better address these problems sometimes we need to try out different models and ideas including those published in research papers. We also have weekly machine learning talks where we discuss machine learning trends and relevant research papers. If you are interested in working on machine learning related problems join us !
How did researchers figure out how to build a Turing machine and other structures in Conway's Game of Life?
Firstly the CA rules were selected italic specifically because they produced behavior that was likely to lead to universalputation. Conway abandoned any research into the CA about the same time Gosper constricted the glider gun because he and his friends were able to sketch a proof that it was universal. That done he was profoundly bored by the subject and moved on. Now the UTMs that were eventually constructed were nothing like the monstrosity that Conway described. The first one although still large was much morepact than those ideas and this was thanks to decades of hobbyist research uncovering new technologies. In part these technologies were designed by hand using knowledge of the behavior of known patterns uncovered by decades of following the evolutions of every starting pattern with a small number of live cells or that fits in a certain small initial bounding box. But in part they were uncovered byputer programs like Beautiful Soup italic which just randomly turn some cells on and see what happens to them over time and whether any interesting behaviors or structures arise. The largest part of the CGoL research of the past three decades has been focused on Software to evolve patterns more rapidly (Hashlife Golly) One of the most important technologies for the purpose of designing a UTM is the Herschel conduit italic . A Herschel is a very unstable puffer that throws off a lot of sparks as it moves. It gets its name from the small Herschel-shaped initial pattern that it evolves from If allowed to evolve in an otherwise empty field eventually the random garbage it throws off will catch up to it and destroy it* but placed on a very carefully designed track of still lifes that debris can be absorbed or more importantly transformed. italic Some of it can be used to interfere with the Herschel to change its movement turning it around or side to side or even splitting it into two clones. Some of it can be used to offset the Herschel change its phase slow it down or speed it up. Some of it can be used to create gliders or to catch gliders and turn them back into Herschels. Some of it can be used to toggle between still lifes depending on the last direction a Herschel came from. All of this technology together has a very obvious purpose signaling. A Herschel moving along a track can be used like an electron moving along a wire. And 99% of creating useful circuits for doingputation is just being able to signal. Once you know how to build boolean logic circuits using various patterns that interact with gliders and Herschels building a UTM is just a matter of being able to send signals between these circuits with the correct timing italic . In conclusion I say that building a UTM in CGoL is an engineering italic project. Creating the tools was about half playing around and half sophisticated search techniques but putting them together into a working model was entirely an act of engineering in the strictest sense of the word. It involved largemunities acting in concert generating ideas connections and new ways to use the tools they've found. They ask questions of the form Ive found an X that does Y in situation Z but it takes N ticks to reset. Can it be redesigned to use only use T ticks to reset and fit in this bounding box? and they collaborate to make it happen. There was very little mathematical proof involved at any point. Anything that needs proving had been proved long ago back in the days of Church and Turing and friends. *As demonstrated here s
