![]() ![]() Remember, the chairs don’t have to be all the same! You can mix them up, as long as they fit your general style. Instead of a bench, we have added another sofa chair. As before, the sofa is facing the fireplace. This living room layout is a take on the very first one. The one That’s all About the Crackling Fire Want some extra lighting? You could place lamps between the two chairs at the top, or next to the single chair at the left. We arranged the sofa and sofa chairs around a center point right in the middle of the room, the coffee table. If you don’t like arranging your furniture diagonally in a room, this layout idea might be better for your living room. ![]() But that’s on purpose: there are 2 entrances coming in from this corner, which means that people will move around a lot in this corner. You might wonder whether the right bottom corner looks a bit empty. We have solved this by filling the space with a table and a lamp at the back of the sofa. As the sofa goes diagonally into the room, it has created an awkward, triangle-shaped, empty space between the sofa and the wall. The chairs are directly opposite the sofa and provide a nice counterbalance. Here, we also have a sofa and three sofa chairs, but we rearranged their placing in the room. It’s a great way to add extra seating while not taking up too much space. And as it does not have any arms, it looks less bulky than a proper sofa. Have you noticed the bench next to the French doors? It provides extra seating in case you’re hosting a bigger group. ![]() Having a variety of lighting sources lets you create a warm and intimate atmosphere in your living room. We also added lights: There’s a lamp on a little table next to the sofa and a floor lamp between the two chairs in front of the window. This layout allows gatherings of small groups as well as more intimate conversations. A big, cozy carpet ties all of these furniture elements together. Three upholstered chairs are grouped around it. The centerpiece of this living room is the sofa in the middle of the room, facing the fireplace. Here are our 12 different layout ideas for this space: 1. Of course, there are windows too – a lot of them! They cover two sides, which does not leave us much wall space to put furniture against.There are French doors at the top and three more entrances into the room, from the kitchen on the left, and the hallway and bedroom on the right.At the bottom of the room, you can see a kitchen bar and stools, which connect to the kitchen.Our room is 20 foot square with a fireplace in the corner (our first challenge!).To start with, here are some details about the living room beast we’re dealing with today: Some are even more challenging, though and will constrain you in your choices.īut no need to despair – every room can be conquered! Today, we’re tackling a very special kind of room. Every room will have some things that are hard to change, for example, the location of doors and windows. You did it.īut it is also a whole lot of work, especially if you have a room with very particular requirements. One of the hardest things to figure out when you move into a new space, is how should I layout the furniture? Roomhints has come up with 12 unique layout hints for your square living room with a corner fireplace.įurnishing or redesigning your living room is fun: The feeling of success when you find the perfect coffee table, discovering an amazing color scheme and finally, that moment when you sit back on your couch and gaze over your newly designed living room. ![]() ![]() This typeface is available within Office applications.

Specifically, the crew failed to recognise that the plane's pressurization switch was in the "manual position" before takeoff and not set to automatic - which would have allowed the cabin to pressurise by itself.Īfter take-off, the plane failed to pressurise and the two pilots did not recognise "the warnings and the reasons for the activation of the warnings," including one showing that the oxygen masks dropped. The report concluded that the two pilots failed to competently operate controls regulating cabin pressure and misinterpreted a subsequent warning signs which led to the crash. It crashed at Grammatiko, north of the Greek capital.Īll 115 passengers - all Greek Cypriots and Greeks - and six crew were killed on the flight from Cyprus to Prague which is the deadliest air disaster in the history of Cyprus and Greece. His heroics were witnessed by pilots of two fighter jets sent up when Flight ZU 522 lost radio contact. His girlfriend a stewardess, was also on board. ![]() ![]() The remains of Mr Prodromou, who had trained as a pilot but been unable to secure a job, were found in the cockpit. This caused everyone aboard, except for the steward Andreas Prodromou, 25, to fall unconscious. The official report says technicians in Cyprus who were checking the decompression system - following problems on an earlier flight - forgot to switch on its automatic activation.īut once airborne, this omission was compounded when pilots forgot to check whether the system was switched on automatic or manual.Īs a result, the higher the plane flew the less oxygen was in the cabin. This turned the plane into a "flying tomb" at 34,000 feet as passengers were frozen to their seats by temperatures of minus 50c.Ī steward fought desperately to save the stricken plane after he found the pilot and co-pilot unconscious.īut after he too was overcome, the Cyprus-based Helios Airways plane ploughed on for nearly two hours on auto-pilot before running out of fuel and crashing into a mountain 25 miles north of Athens on August 14 last year. It blames the pilots for failing to spot the warning signs that led to the tragedy in which the Boeing 737-300 airline was hit by a catastrophic loss of cabin pressure and oxygen supply. Human error by two pilots led directly to a packed passenger plane turning into a frozen "flying tomb" before it crashed - killing all 121 on board, the official report has concluded. ![]() ![]() ![]() But still, the future of the algorithm does look promising. ![]() Scrypt will be better than bcrypt in time, but it hasn't seen adoption as a standard by Linux/Unix or by webservers, and hasn't had in-depth reviews of its algorithm posted yet. Best practicesīcrypt and scrypt are the current best practices. No password is truly good enough for our purposes, so we must protect them as though they were in Fort Knox. Either its not memorable, too predictable, too short, too many unicode characters (hard to type on a Windows/Mobile device), too long, etc. So far as I've been able to tell, making the world's best password is a Catch-22. Randomess, as truly random as possible, is always the safest but least memorable solution. In the comments I talked with who pointed out that enforcing a password policy of X length with X many letters, numbers, symbols, etc, can actually reduce entropy by making the password scheme more predictable. A good Google search will also turn up a lot of results. There's a longer discussion of password entropy on the Crypto StackExchange site. But the good news is: longer passwords, and passwords with unicode characters, really increase the entropy of a password and make it harder to crack. Using the full range of ascii characters (roughly 96 typeable characters) yields an entropy of 6.6 per character, which at 8 characters for a password is still too low (52.679 bits of entropy) for future security. One problem is, to make our passwords memorable we insert patterns-which reduces entropy. But allowing upper and lower case, with symbols, is roughly 96 characters. Alpha-numeric passwords are better, with 36 characters. When a password is only lowercase roman letters, that's only 26 characters. ![]() In short, entropy is how much variation is within the password. (Not that I fully subscribe to Randall's viewpoint.) (Emphasis mine.) What makes a good password anyway?Įntropy. This might be common knowledge to password and crypto pros, but for the average InfoSec or Web Security expert, I highly doubt it. If you don’t know how your password is stored, then all you really can depend upon is complexity. I’ve come to appreciate why password storage is ever so much more important than password complexity. Interestingly, in living out this nightmare, I learned A LOT I didn’t know about password cracking, storage, and complexity. Jeremiah Grossman, CTO of Whitehat Security, stated on White Hat Security blog after a recent password recovery that required brute-force breaking of his password protection: If your database is compromised you will need enough time to at least lock the system down, if not change every password in the database. And time/cost are the best deterrents in your arsenal.Īnother reason that you want a good, robust hash on a user accounts is to give you enough time to change all the passwords in the system. So the goal of password hashing is to deter a hacker or cracker by costing them too much time or money to calculate the plain-text passwords. The objective behind hashing passwords is simple: preventing malicious access to user accounts by compromising the database. (See the "What makes a good password?" section for some debate.) This will improve the entropy of the password, in turn making it harder to crack. Implement a reasonable 8-10 character minimum length, plus require at least 1 upper case letter, 1 lower case letter, a number, and a symbol.Reset everyone's passwords when the database is compromised.Use PBKDF2 if you cannot use either bcrypt or scrypt, with SHA2 hashes.Use scrypt when you can bcrypt if you cannot.(This applies to any input that may have a rogue \0 in it, which can seriously weaken security.) Don't mix bcrypt and with the raw output of hash(), either use hex output or base64_encode it.Never hash passwords with SHA1 or MD5 or even SHA256! Modern crackers can exceed 60 and 180 billion hashes/second (respectively).Never, ever log passwords in any manner. ![]()

He added: “Today’s rockets are a challenge to Nato, to collective security. “Unfortunately there are victims,” he said. In a short video report on Friday Volodymyr Zelenskiy said Russia had targeted civilians and civilian architecture. ![]() They say Moscow deliberately targets Ukraine’s international border regions so when missiles are intercepted debris falls on neighbouring countries such as Poland and Belarus, itself a frequent launching pad for Russian plane and rocket attacks. Ukrainian officials describe Russian behaviour as cynical and provocative. It was the first attack on Kyiv for two weeks. A trail of white vapour could be seen above tower blocks and the railway station area. There were five booms in the Ukrainian capital, as air defence batteries shot down enemy missiles. On Friday, Moldova’s pro-EU government resigned, adding to the sense of crisis.Īir raid sirens sounded in Kyiv and other cities around breakfast time on Friday. This is not the first time Russia has sent its missiles into Moldova, with the conflict now in danger of spilling out across the region. Moldova summoned the Russian ambassador over the incident and confirmed at least one missile had overflown its airspace. It “constantly monitored” the vicinity next to Ukraine and cooperated with allied forces, the ministry said. Romania has been a member of Nato since 2004. “After about two minutes the situation was clarified and the two aircraft resumed their original mission,” the ministry added. Two MiG-21 aircraft on a training flight were diverted to monitor the area, it said. It said the Russian cruise missiles came to within 22 miles (35km) of the country’s north-eastern border but did not violate its territory. Romania’s foreign ministry categorically denied the report. They then reentered Ukraine and the western Chernivtsi region, he suggested. Ukraine’s commander in chief Valerii Zaluhnyi said two of these sea-launched rockets entered Moldovan and Romanian airspace soon after 10am local time, as air raid sirens rang out across the country. On Friday, however, Moscow launched Kalibr cruise missiles from a frigate and a submarine in the Black Sea, as well as from the occupied southern city of Tokmak. Ihnat said Russian forces “traditionally” dispatched rockets and drones from eastern positions in Russia and the Azov Sea. Western governments expect Vladimir Putin to launch a renewed bid to grab territory ahead of the anniversary on 24 February of his full-scale invasion. The command’s spokesperson Yuri Ihnat said the Kremlin appeared to be carrying out a “reconnaissance attack” ahead of a possible major offensive. ![]() ![]() Thus, bad buys may pay less attention to them becauseįew people use them.
