Воришки

В пятницу через себя прочувствовал, каково это, когда у тебя украли велосипед. Ладно, если б при этом ещё и морду набили – было бы не так обидно. Велосипед был пристёгнут цепью Abus 6Ks, но злоумышленник саму цепь оставил целёхонькой лежать на земле: пала раскушенная 6-мм дужка замка.
Погуглив выходные, я взял на заметку несколько советов, которыми, конечно, стоило вооружиться раньше. Всё равно, они ещё послужат хорошую службу:
  • Сделайте велосипед максимально опознаваемым. Например, обклейте его отражателями, разноцветными элементами или другими отличительными знаками.
  • Можно пометить велосипед. Например, выбить аббревиатуру, например, или сделать заметный знак. Как правило, угонщики, если замечают это, то не решаются на кражу – легко потом опознать. Конечно, если вы сами решите продать велик это снизить стоимость.
  • Используйте как минимум два замка разных конструкций, например, цепь, U-замок, кольцевой замок. Многие злоумышленники специализируются (или имеют в наличии необходимые инструменты) только на определённом типе замка.
  • Не цепляйте велосипед только за раму: прихватывайте и колесо. При этом если злоумышленник будет ломать цепь кручением, есть большая вероятность повредить обод колеса. Кому нужен велосипед с восьмёркой?
  • Просто и эффективно: уходя, заберите седло с собой. Ехать быстро без седла как-то не очень комфортно.
  • Если у вас есть время, вы можете отсоединить переднее колесо и пристегнуть его  цепью к заднему. В конце концов, злоумышленнику важно быстро уехать с места преступления, и он будет оценивать свои риски быть застуканным. В среднем по 2 минуты на замок и столько же на установку колеса: кому охота возиться 10 минут?
  • Не используете на велосипеде зажимы, которые позволяют быстро снять переднее колесо или седло (если не собираетесь его всё время снимать): установите вместо них обычные гайки. Вы же не часто меняете камеры.
  • U-замки должны быть на плоских ключах (круглые взламываются).
  • Я обратил внимание, что в магазине можно купить кусачки длиной 480мм, которые перекусывают 6мм металл. Поэтому и покупать надо из этого расчёта. Лучше 12мм цепь.
  • Замки не должны лежать на земле, чтобы исключить взлом при помощи молотка или злоумышленники не могли поставить второй рычаг на землю и использовать свой вес тела.
  • Можете попробовать экзотические способы борьбы: Pedal Lock  от Cheng-Tsung или GPS трекер SpyBike или поднять на столб, но мне кажется, что это скорее "война ради войны".
  • Сделайте фото чистого узла каретки снизу – там находится номер вашей рамы. Или запишите его – он может сыграть огромную роль в поиске.
  • Полагаться на прохожих не стоит, ибо наглость воришек не знает предела.
Успехов всем и не попадать вот в такую ситуацию:

Посылки и пошлины

Из моих наблюдений:
  • На посылки внутри еврозоны (включая Великобританию) импортные пошлины не налагаются.
  • На посылки с заявленной стоимостью ниже $50 импортные пошлины не взимаются.
  • Посылки, для которых не заявлена стоимость на экспортной декларации и которые тяжелее (предположительно) 1 кг, просвечиваются сканером. При обнаружении там электроники конечный адресат получает письмо от PostNL, в котором его просят оценить стоимость посылки.
  • Налог считается так:
    • €17 – сбор за обработку посылки. Платится в любом случае.
    • 30% – импортная пошлина на электронику, вычисляемая от стоимости посылки.
То есть, если заявленная стоимость посылки $60, то вам выставят счёт €17+€13.8=€30.8, что оставляет более половины стоимости посылки. Поэтому:
  • Просите продавца указывать стоимость не более $50.
  • При получении письма от PostNL можно сфабриковать счёт-фактуру или выписку из PayPal.
  • Если вы уже поставлены перед фактом, то всегда есть возможность отказаться от посылки, которая будет отправлена назад. При этом можно договориться о повторной доставке, что может оказаться дешевле, чем заплатить пошлину.
Если у кого-то есть факты, опровергающие или подтверждающие вышесказанное, то прошу оставлять комментарии.

The less the better [or wine with torrent]

Nowadays a lot of compact devices (like media players or TVs) have Torrent client on board, why should anyone bother about the exotic way of running it? Well, in my case the main reason was that I was migrating uTorrent from my laptop to standalone server to allow 24h non-stop feeding. So, let's put everything in one bottle:
  • It was important for me to have less fuzz with migration of about 100 torrents from my laptop. Perhaps that would also be possible for uTorrent for Linux, but I also get used to UI interface & settings.
  • Running uTorrent on server gives me the possibility for non-stop feeding and downloading on demand.
  • Running uTorrent on Linux also have a potential bonus of configuring QoS in case torrent traffic gets annoying. Yes I know about build-in bandwidth settings, however the typical task is usually "I want uTorrent to consume all bandwidth unless there is something else hungry for it". In this case all traffic for internal network should go via server that unfortunately, adds one more point of failure in the chain.
Technically all above can be solved with following setup:
  • We will run Xtightvnc server on Linux. It acts as X-Server and uTorrent will display it's UI on this server. Bonus is that Tightvnc has clients both for Linux and Windows, which will allow you to connect to under from any (popular) platform.
  • We will run uTorrent with wine. Certain versions (like v1.8.5) do not start under wine on some reason, so you'd better double check here that certain version was tested under wine or use /noinstall command line option. Keep uTorrent window on separate workspace & collapsed. Also disable "Show current speed in title bar" to reduce number of UI update events.
  • Hint: When launching  uTorrent also pass the /minimized option. Otherwise it will consume 5% of CPU just to render constantly changing statistics (Tightvnc needs also to response to any UI update even if no client is connected). When minimized it will be 1-2%.
What uTorrent client to choose? Well, I personally have stopped on v1.8.5, because:
  • I do not need magnet URLs or life streaming features in v3.x. The last one is by the way in most cases failing for me (perhaps always fails for MKV container, is it not so suitable for partial playing).
  • The sad trend shows the sad statistics: uTorrent executable size was slowly increasing by 100Kb in 2007-2011 (from 100K to 500K), but in 2011-2012 it doubled in size (from 500K to 1M). Perhaps it's still the smallest torrent client, but with every new release I doubt more and more.

Робопылесос Paranello


Недавно появился у нас дома новый помощник: робопылесос Paranello. Алгоритмом его прохода по комнате я в целом доволен: робот меняет несколько стратегий чистки и за пару часов он сделает пол заметно чище. Был приятно удивлён его способностью найти базовую станцию, запрятанную за TV столиком вне прямой зоны видимости, и способностью огибать по периметру ножки (стола) и выступы (стены). Возможность ручного управления движением робота с пульта ДУ забавляет взрослых пап и возбуждает малышей. Главное правило: почаще вытряхивать контейнер с мусором и прочищать воздушный фильтр, который за пару сессий забивается песком. Тем не менее, за прошедший месяц он несколько раз застрял:
  • Один раз намотал на щётку шнурок от ботинка. Перевоспитываемся и прячем шнурки внутрь.
  • Один раз он наехал на маленькую деталь от конструктора, засосать не смог и съехать тоже, но правильно определил "неполадку" и остановился. Берём на заметку и убираем все мелкие вещи с пола.
  • Один раз намотал на щётку гардину, которая касалась пола. Мы же мотаем на ус и стараемся подвешивать гардины на расстоянии.
Производимый шум (который, конечно же, меньше обычного пылесоса) хотелось бы ещё уменьшить, но это – совсем другая история.

По НТВ в передаче "Чудо техники" рассказано, как тестировать роботов.

Buying the house

Buying a house is indeed very exciting story. The most exciting is no doubt the process of bidding, when you communicate the amounts which you will never see in your hands. But let's not jump too far.

Even before starting to think about whether you want to move, read the article From search to purchase in my wiki to get more familiar with how it happens. Don't be too scared: at the end of story the feeling of lying in your own sofa in your own garden or balcony if worth going through all difficulties and scaring decisions. And of course, property is generally better and more reliable investment then bank savings as:
  • Provided that you have taken a mortgage for 4-5% and normal inflation is 2-3% then you have been credited for just 2% which is very cheap.
  • Property trend to rise in price faster then inflation.
  • Government provides you with tax return.
On the other hand buying a house always results some extra costs (about 10% of the property value), which you can't afford often in your life.
First of all try to compose the list of features that describe the house of your dreams. For sure the 1st version of this list would be incomplete and ugly. Now search different sites offering houses for sale and visit few of them. Revisit your description list and try to specify them better and in more details with fresh examples in mind. Ask real estate agent stupid questions, which you may run into. This will help you to come up with better description of your house (my description is here) which you can even send to agents: some of them (I met only two out of ten) are happy to see this description to offer the best from their database. In general search over all agents and all other sources costs money but perhaps it will result the house of your dream − it's up to you to decide whether it's worth the money.

Create a check list of typical questions. I personally was interested in following:
  • Is there running guarantee for the kitchen appliances (oven/fridge)? Usually the appliances have 3 years guarantee, but if owner has ordered all from one producer (e.g. Siemens), he may get the special guarantee for 5 years.
  • How many working surfaces the kitchen has? Is there enough place for cookware? Is kitchen surface a stone?
  • Is deep freezer located in kitchen? Modern deep freezer is usually 4-stars (see Temperature zones and ratings). Sometimes it is placed in cloak in the garden, which is not handy.
  • Does oven have a self-cleaning function? Zanussi / Electrolux should have models with this function (but maybe for models after 2006/2007).
  • Check the laminate (scratches / traces from furniture). Thickness of laminate on ground floor should be 8mm.
  • Floor heating is considered to be more effective then radiators, but it should not be used if floor is not tiled (less effective).
  • What is the energy label of the house? If the agent assures you it is A, don't trust him by word: this level of energy efficiency is difficult to achieve. Usually for 10-years old (or younger) houses it is B or C. For houses older than 10 years the presence of energy label certificate is obligatory for property transfer deed (see energielabel.nl → Is een energielabel verplicht?).
  • If house is older than 10 years or younger than 3, everybody would suggest to make a structural report. Otherwise check that GIW guarantee is running (it lasts the first 10 years for walls / basement / roof, first 3 years for windows and 1 year for painting) and this insurance will be transferred to new owner.
  • Check the side costs (heating, electricity, WOZ and other taxes). Sometimes they are provided by agency in a formular that house seller fills in, if not − ask to provide you. Note that at the notaries you will have to pay back the current house owner part of the taxes for the rest of the year, which he has paid at the beginning of the whole year.
  • Is house facing the busy road? Highways will disturb you also at night but due to good isolation you will not hear them with closed windows. Road next to your window might wake you up at six in the morning and cause more troubles. Think about the ecology and safety of your family. The trade-off is always the time you need to get to your office by car, as you'll spend more time to get to highway.
  • How far is the social block (sociale woning) located? Each agent will give you different information, but you may be lucky to meet the agent that leaves in this area and he knows, what area results most complains and problems. Objectively it is difficult to judge, as private houses can be rented and rental block may be very quiet and all blocks are mixed.
It is wise to search in parallel the mortgage advisor. Contacting the mortgage services of the bank (that serves your debit account) will not harm, but my feeling is that your bank is not willing to offer you other rates than "standard" defined by bank policy. On the other hand mortgage advisers have direct connections with several mortgage providers and they know how to trade. Each tenth of the percentage of the rate in my case is €20 less per month payment. Not much, but %0.3 is already good money. More over mortgage advisor will be more willing to answer all your questions, as his salary at the end of the day will depend on whether you are his client (in contrast to bank clerk). The advisor will take care of all financial questions (mortgage type, the period to fix the percentage, best way to invest your savings, advise the notary, plan future expenses, provide the house insurance and personal life insurance). I would personally recommend Jan Augustinus from Aandacht Hypotheken. I have chosen the annuity mortgage with the following conditions:
  • Be able to sell a house at any moment and return the debt to the bank with no penalties.
  • Be able to pay back 10% of house cost each year.
  • Period: 25 years
  • Percentage fixed for: 10 years
Under these conditions I was offered 4.65% per year. By the way, if you want t go beyond 106% of market value for mortgage, then you can do it by doing the renovation in your house. When choosing the mortgage type you may consider these options:
  • If you are sure, you will cell the house and move from the country one day, then interest-only mortgage may look attractive. You will pay around €800 interest monthly (tax return included), which is less then renting the house.
  • Even though the conditions allow you to return certain amount of house cost per year, it is not advisable. The reason is that bank gives you money on very low percentage. If you have spare money, don't bring them to bank: invest them into another property or shares. For example you can take a mortgage for whole house price but payback the mortgage only partially. When mortgage period end, you bring the accumulated assets to bank. However you loose money on higher interest payments.
Concerning the life insurance: by law you are obliged to insure a certain amount of the mortgage. This money will be paid back to your partner to somehow survive in worst scenario. The amount of mortgage to be insured in my case was €37.900 (mortgage − purchasePrice × 80%), which results €93 per year. In this respect the advisor will ask you about your pension plan, as in case of death wife is entitled to get 70% of your accumulated pension, and children – 14%, which will help them significantly. By the way, when you reach the pension age, your wife is entitled to 50%*) of your pension that you've build throughout the period of your marriage, even if you are divorced by the time your are retired.

Special attention should be given to NHG. It costs 0.7% of the mortgage, but it's worth these money, as banks provide you with better mortgage rates and you save many thousands and the end of the day. If the house price is above the insured by NHG limit, try to make a deal with buyer and pay the difference with cash so that the purchase price on paper allows you to acquire it.

Finally you have searched and visited all potential houses and you have defined the top one and you are ready to make an offer. It is generally accepted rule that you have one valid offer at a certain point of time. That means you'd better avoid making offers for several houses (and agencies) in parallel. Agencies will pay back to you and guarantee that once your offer is considered by house owners, other new clients will have to wait until you finish your negotiation round with seller before they are served. In positive case (you and seller came to agreement) you can buy the house. Otherwise you withdraw your offer and exercise next house in your list. It may happen that you will return to 1st house in your list again, but at that moment the agency might have already had another client. In case if several clients are willing to make an offer agents open an auction and allow clients to bid. The procedure how to make offer is usually described on the last page of the brochure, but common is to write an email or fax. Your offer made by email is binding, however you can quit even after you put a signature on purchase contract (you have three days reconsideration period).

Congratulations, you have committed to buy the house! The contract which is offered by NVM-certified agency is standard (the description of all articles is available in English) and does not require a lot of attention. As far as I know it was introduced in 2003 to protect both seller and buyer. It can be further extended by additional articles on your request. I personally asked to formalize additionally two things (I think they are applicable in many cases):
  • Buyer can cancel the contract if structural investigation reports problems, that need to be fixed/repaired in short term (within one year) and exceed €1000 in total.
  • Include the list of items that seller agreed to leave in the house (in case you have immovable and movable properties combined in one price).
Few interesting details which I've learned from description of contract articles:
  • The Soil Protection Act may force the owner of the ground to put it in order. That is why the attention is drawn to any oil tanker in the ground which purchaser should be aware of. This tanker have been used in old houses to provide the heating system with fuel. After the central heating has been introduced they are not used. However the purchaser is responsible to check everything before buying:
    The expression “was aware of” is wider than “knew about”. Even defects the purchaser did not know about but would have discovered if he had made sufficient effort are ones he could have “been aware of”. So the purchaser can’t just simply assume that everything is in order. It is expected that the purchaser will investigate or arrange an investigation as to whether the property meets his requirements. The phrase “what you don’t know won’t harm you” does not apply here. Where there’s any doubt, the purchaser must ask questions and/or carry out some investigation.
  • Another interesting article is 6. For me it was new to learn that one can lease a kitchen or boiler. However the purchaser should either take over these obligations of get the house free of any. The same concerns renting.
Now you need to do few minor things: choose the company to make a structural report and choose a notary to complete a deal. The notary should be in 15km distance from the property, otherwise you'll have to pay transportation costs for other parties. Prices for the the notary range from €950 till €1350 for two deeds package. Some of the notaries require the translator from Dutch to English to be present (which is required by article 42 of the Notaries Act) that adds around €300 to the price. The structural report (optional) and market price valuation report costs are around €300 each. Be present during the structural investigation, ask questions: this will help you in maintaining the house and also you will learn about how to check if something went horribly wrong. Ask the house owners about the following:
  • The laminate label / provider (in case you need to repair it).
  • The front windows / door color number (which you need to repaint each few years).
  • What is the agreement between neighbors concerning the fence in the garden (which one day needs to be replaced).
  • How to use kitchen appliances.
  • Where the kitchen was bought (if you need extra kitchen boxes).
Another question which you might be interested in is the inheritance of the property. Unfortunately, in The Netherlands you cannot gift the property to your children without paying taxes. What are the alternatives? OK, first of all, you can cell the house to your child. This goes the normal way, so you need to pay 2% of transfer tax and about €750 for notary for property deed. When selling the house you can't put the price too low: it can't go below WOZ price. Another alternative would be to gift a house: in this case you need to refer taxes for gifts. The amount of money you can gift your kid without paying any taxes is €19.114+€50.300 and if the house price is €250.000, then you need to pay 20% from €180.586. Situation changes if you have two kids: then you pay 10% from €111.172, which will approach the price you pay when you cell the house. Another schema allows you to gift a kid €5030 every year (should be made via notary) until he/she is 18 years old (which is €90.540 by full age). If you are sure your kid will not become a mafia member and will not kick you off you own house, you can try this way. In later case you can split the house cost between two kids with no big extra costs, but you need to trust your babies ultimately as in worst case you will find yourself on the street.

*) I would be happy if somebody provides me a link to prove this information.

Skype downgrade


Something goes wrong with Skype 5.8. After returning from a sleep or hibernate on Windows7, Skype hangs as soon as there is a new incoming message or event when you try to open it from a tray. Not simply hangs, but starts consuming 100% of CPU. Weird. It looks like it comes into collision with some other (relatively rare) software as otherwise it would have been reported and fixed very quickly. Thanks to software collections, it is possible to go back in version and stick to one which is working. First let's check what functionality we loose if we go back from v5.8 to v5.7:
  • Full HD video-calling
  • Support for Facebook audio and video-calling (beta)
  • Group screen sharing
  • Hide offline Facebook contacts
  • Push to Talk
  • Skype updater service
  • Bing Toolbar integration
I am not Facebook user, I don't have any relations with Bing (MSN). Full HD is cool, group screen sharing looks to be introduced in 5.7.0.123 (and perhaps improved / bugfixed in 5.8), but I can sacrifice it: I haven't used group conferencing so often and especially with screen sharing. Also Skype version 5.5.0.119 has no more annoying Skype Home page pop-up in compact mode.

Now comes the interesting part: how to disable the updates? It turned out that there is no way to do it via settings dialog nor via any other option in the menu (reported as issue SCW-3173). You may find the reference to DisableVersionCheck registry key but it was reported that this registry setting does not prevent forced updates by the skype network. So finally the only reliable solution is to block outgoing packets to IP addresses 204.9.163.158 (from Jan 2012: 204.9.163.247) which unfortunately will effectively break the lightweight installer which utilises the same mechanism for installation so you will have to download the full Skype version each time when you want to update. Another advise: create a dummy file named SkypeSetup.exe in %temp%  and assign the security Everyone: deny.

And now the final accord. From ongoing discussion I've found out that as to terms and conditions §5.3 Updates to the Software Skype may require you to automatically download and install Updates from time to time in order to allow you to use the Software which means "if you don't update, Skype may stop working". How do you like this?

P.S. List of IP addresses to block:
