Alternative approach is to develop a small app that could be run locally, or that could be sent to colleagues to run locally. So, Jupyter notebook is one way to create visualizations through exploratory data analysis. 4), for instance Bokeh Crossfilter Example application that illustrates autompg dataset.

Once the ColumnDataSource has been created, it can be passed into the source parameter of plotting methods which allows you to pass a column’s name as a stand-in for the data values (Fig. If one positional argument is passed to the ColumnDataSource initializer, it will be taken as data. The ColumnDataSource takes a data parameter which is a dict, Pandas DataFrame. When data is passed like this, Bokeh works behind the scenes to make a ColumnDataSource for further plotting.Īt the most basic level, a ColumnDataSource is simply a mapping between column names and lists of data.

Andrew Cuomos argument that a new state ethics commission was created in a way that violated the State Constitution. Governor Cuomo said that “I fully support a women’s right to come forward, and I think it should be encouraged in every way,” and that he “never touched anyone inappropriately.” He apologized for the hurt he caused and asked that people wait for the facts from the state attorney general’s investigation before forming an opinion.

They did come fix the lock on the door when I called about it, but try explaining to 3 children under 8 why Mommy has to lock them in their bedrooms that night because the door doesn't lock. The Jeeves people could have killed someone with their irresponsible, shameful tactic of locking me out because of their own mistake. GOOD THING THE BACK DOOR DOESN'T HAVE A FUNCTIONAL LOCK!!! Otherwise I'm not sure she'd have been able to get it open and God only knows what would have happened. My daughter started to scream and cry and I finally got her to go around to the back door to let me in. My pot of food was beginning to smoke on the stove and my 3 children were still inside. I WAS ALREADY CHECKED IN! At the time they decided to lock me out, I was cooking dinner for my children and they left me standing outside unable to get back in. Sent me an email stating that and threating eviction procedures. I said no, I'll bring it by in the morning and they LOCKED ME OUT of the house by changing the door code. They actually checked me in and then had the audacity to call back an hour later saying they forgot to make a copy of something and I needed to come right back. I didn't find this out until it was midnight and I could finally relax after the whole day of travel and hassle with the Jeeves people about their insane check in procedures. The master toilet also did not work and my husband was so sick of calling the office about all the problems we had that he decided to fix it himself (which he did, but the pipes in the walls behind the toilet still made a horrid, loud screeching sound each time it was flushed and would continue to run). The first floor bathroom toilet didn't work. That meant we got to enjoy one night of our stay with cool and and that was the only night that one of my three children didn't come into our room crying because they were "too hot to sleep." Unacceptable! Finally that night it cooled it down to 72 degrees. On day 4 and after more calls letting them know it didn't even cool the house below 82, they finally sent the same guy who spent the whole day walking in and out of the house working on replacing a part that he admitted he should have just done on day one. I don't even know how many times I called asking for them to fix it and each time they sent the same person who would look at it and tell me to "be patient, it SHOULD cool a degree per hour" once it gets dark. The AC in the house was broken upon our arrival. It only took 8 or 9 phone calls for them to make the gracious offer for that refund. The water in the pool was SLIME and they were so kind as to eventually offer to refund the extra $200 I was charged to heat the hot tub (which is such a scam it isn't even funny). They smelled like disgusting stink water so we couldn't even sit out back to eat or enjoy the spaces nearby. How I wish I had not done that! I chose this property because the house came with a pool and hot tub and my children thought that seemed like SO MUCH FUN! Turns out the pool and hot tub were broken and would not be fixed during our stay. I made the mistake of cancelling the townhouse I'd reserved at another resort and booked this house for our 5 days in Orlando. Not one we’ll recommend or rush back to in the future. The phone on the villa didn’t work and wouldn’t connect us.Īll these things together left us with a feeling of encore being an average resort. We tried to call the number that was on the leaflet on the villa to request more towels. What we had was a small pool, 3 sun loungers and a table that seated 6. The picture of the pool in the brochure was stunning. We dealt with all of that, but it’s disappointing. Also not enough plates and glasses for everyone at once. On returning it became clear there wasn’t enough seats around the dining table to all eat dinner together. A rushed breakfast and out the door for a day of fun. The next day was an early start at the parks. We’d had a long day (one lost suitcase) and with the time difference it wasn’t something we wanted to do anything about at the time. Arguments ensued as the kids decided who slept where. Once they left, I realised the bedroom set up wasn’t as we’d been told. They showed us around and gave us the number to call if there were any issues. They checked us in swiftly and took us to our villa. On arrival we were greeted warmly by the staff member at reception. I spoke directly to Encore concierge and asked if the villa would have 3 double rooms and 3 twin rooms. Before we travelled, we confirmed with encore the set up of the villa. We were a group of 12, 3 families, 6 adults and 6 children. The picture on the brochure of the fabulous outside villa pool area and central water park sold Encore to us. We booked in the UK with an independent travel agency that uses Gold Medal Travel. slay both the lame and blind, which hate David's soul" as it is in Septuagint. The allusion in 5:8 may be read, "Whosoever smiteth the Jebusites let him. In 2 Samuel 5:6 it was a taunt on the part of the Jebusites that even a garrison of cripples would suffice to keep out the Israelites. In the enigmatical and probably corrupt passage describing David's capture of Jerusalem, the lame and blind are mentioned twice. The inequality of the legs of the lame is used in Proverbs 26:7 as a similitude of the ineptness with which a fool uses a parable. Job in his graphic description of his helpfulness to the weak before his calamity says, "And feet was I to the lame" ( Job 29:15). The unfitness of the lame for warfare gives point to the promise that the lame shall take the prey ( Isaiah 33:23). In the prophetic description of the completeness of the victory of the returning Israelites, it is predicted that the lame shall be made whole and shall leap like a hart ( Jeremiah 3:18 Isaiah 35:6). (2) Those who suffered from lameness, such as Mephibosheth, whose limbs were injured by a fall in childhood ( 2 Samuel 4:4 9:3). The offering of animals so blemished was one of the sins with which Malachi charges the negligent Jews of his time ( Malachi 1:8-13). I understand his obit will be in the NY Times Friday and Saturday.(1) The condition of being unable or imperfectly able to walk, which unfitted any descendant of Aaron so afflicted for service in the priesthood ( Leviticus 21:18), and rendered an animal unsuitable for sacrifice ( Deuteronomy 15:21).

Ohh, Archangel Chamuel, May you fill our heart with love this day, that we may repeatedly awaken and radiate this love to the benefit of our fellow human spirits. ato show love him to :)and I want to be his soulmate forever in my hearts :). Thank you very much for your beautiful comments.Īww he such a sweet angel. Thankyou website maker for this wisdom, so easily attained. I can call upon Archangel Chamuel to help me be LOVE and give love ^_^ sweet! These crystals are connected to the anahata chakra.

Your reward is going to be a blessed life, filled with love. By spreading your life you create a bridge upon which Angels can descend and bring hope and joy to the world. Let love flow out of your heart to your loved ones, to the ones that you do not love, to people you do not know, to all the people on planet Earth, all animals, plants, crystals, to all Divine creation. With you inner eye see the pink light that surrounds you. True love is powerful, it overcomes insult, anger, and separation, it is stronger than the ego. Love knows no limitations it accepts all people just as they are. He will bestow you with positive emotions of love and adoration, and fill your heart with love and joy. Archangel Chamuel will awaken in you high respect, so that you can devote your being to God. He will show you how to imagine an adequate positive emotion of extreme meaning and value, and then, how to find the golden midpoint between the two opposite emotions - this narrow edge one is advised to balance upon in order to be able walk the path of unconditional love. He will teach you how to transmute such feelings into something positive. If you want to get rid of all the negative emotions, call up Archangel Chamuel. He amplifies the flame of love in your heart, by providing for Divine love and comfort. Archangel Chamuel will show you the way of compassion, love and forgiveness.

Along with Elohim Orion, He works with the energies of the pink flame.Īrchangel Chamuel is an Angel of adoration and glorification. The most prominent representative of the Pink Ray is Archangel Chamuel. Pink Flame Invocations should be performed on Tuesday when this Flame is especially active, and when its manifestation reaches the highest intensity. This is a Ray of Divine love, tolerance, adoration, and gentleness. Through the pink Flame the needs are expressed, plans formulated, and material is selected. Here we see the qualities of creativity and adjustability. From the third Ray of the pink Flame we see the manifestation of the activities, intents, and wisdom of the first two rays: the first Blue Ray and the second Yellow Ray. The good news is that the sequel, The Patrician II has been released by Ascaron in June, 2001, and is enjoying a lot of great reviews from European magazines. If you love The Merchant Prince, you will definitely like The Patrician as well. In addition to the features I mentioned, there are optional action sequences, plagues, spice fleets, and calamities like fires that add to the excitement. The game offers an epic scope and seemingly endless array of options and choices. But if you choose to hire the pirates, or do anything else that is illegal such as bribing city officials, you run the risk that someone will find out about it and decide to blackmail you.īy all accounts, The Patrician is an outstanding game. On the other hand, you may also choose to enlist the pirates' help, by giving them a well-armed ship to raise hell in your opponents' waters. Also, you may need to defend your city from hostile attacks, and send out huge fleets to chase pirates. For instance, getting married is an important part of the game, as you can get a great dowry if you choose the right wife (or husband, if you play as a woman). What makes The Patrician stand out as one of the best historical sims ever made is the attention to detail and the huge variety of gameplay options. If your electorate throws you off the mayor's post, it won't matter how well liked you are in the rest of Europe. You must also remember to keep an eye on your own city, as local politicians won't give up even after you have been elected mayor. selling expensive goods in their city while buying cheap- thus making the city lose money). This is not easy, since city councils will not be happy of your arbitrage operations (i.e. This means that you have to be well liked in as many cities as possible to get elected. mayors of other cities, are impressed with you. If you become a mayor, then you will be admitted into the Hanseatic League meeting that is held every four years, and you can finally get elected Alderman if the other members, i.e. This requires that you "buy" favor from townspeople, by donating money to the poor, funding a new church, throwing parties, etc. After you make a handsome amount of money, you must try to get elected mayor in your home city. The prices are calculated in a very realistic way, taking into account factors like the time of the year, and the amount of goods in the city. In all, there are about 40 commodities to barter with, and 16 cities to sail to. This is done by the usual buy-low-sell-high routine: you sail to one port, buy some goods, then sail to another port and sell the goods at a higher price. To become Alderman, you have to make a lot of money to buy political power. leader) of the Hanseatic League which controls most of the trading. Although not as good as Merchant Prince, The Patrician is a competent game that deserves much more attention than it received, and is an arguably better game for multiplayer competition (the game allows up to 4 human players).Īs a trader living in medieval Europe, your goal is to become the Alderman (i.e. The game is similar to Holistic Design/QQP's Merchant Prince, but with more emphasis on political power and influence. One of the best historical business games ever made, The Patrician enjoyed tremendous success on the Amiga but unfortunately very little attention from PC gamers (the same fate suffered by most other Amiga hits). Now despite this ludicrous premise and some fun central performances, I still do not think I had as much fun as I could have. Finally, Burke’s work as Jonah’s King is easily the film’s weakest spot, because the guy just is not very intimidating compared to any of the three previously mentioned characters. I have already mentioned how great Fichtner is in this film, but I will add one more thing: in the film Red, even if you have only seen the trailer, we all know the scene where Bruce Willis steps out of a speeding car in slow motion well in this film, Fichtner has a move that tops that. Equipped with daisy dukes and attitude, Heard is completely embracing the camp of this movie and doing so while bringing both her beauty and acting talent to a film that really only needs one of those qualities. Surprisingly, I found Amber Heard to be doing a lot better in this film. While there was not enough of the “ Cage Rage” that I would have liked to have seen, he brings enough of what is needed for this role. Regardless, for this movie, in this day and age, who else would you expect to sign up for this role? Of course you would have Cage signing up to be the shotgun toting, car loving, bleached haired, escapee from Hell. Now, why he chooses the parts he does, that is a different story, which probably has more layers than there are in Hell. I can also say that regardless of how bad the flick is, it is never due to Cage, who I always find to be bringing something interesting to the ridiculous parts he ends up playing. I seem to get into a lot of arguments with people about Nic Cage, so I will say right off that I am a fan of his, despite being very aware of some of the terrible films he has been in. Lots of gratuitous violence, nudity, and mayhem ensue brought to you in glorious three dimensions (which it was shot in). Anyway, the rest of the movie boils down to a three-way chase, with Milton and Piper pursuing Jonah and his hillbilly cult members, while The Accountant pursues Milton. The movie may not be an overall recommendation, but every time Fichtner is on screen, the movie jumps up to 4 stars. This is where the best thing about the movie comes in, as William Fichtner’s role as The Accountant is perfect. Since Satan does not approve of his prisoners going on rogue missions, he has dispatched a man known as “The Accountant” to go after Milton and bring him home. The baby will be murdered under the next full moon, unless Milton can stop it, and he plans to do so. We soon learn the story: Milton is actually an escapee from Hell, hoping to find his kidnapped baby granddaughter, who has been taken by a satanic cult leader, Jonah King (played by Billy Burke, doing a very uncool Billy Bob Thorton impression). He manages to get a ride from a hottie waitress, Piper (Amber Heard) with a 69’ Dodge Charger. Nicolas Cage stars as John Milton, a mysterious drifter looking to find some bad men. Milton: What’s he gonna do, not let me back in? The Accountant: Would not want to be you when Satan finds out. There are some great bits in it for sure, with great help from one character in particular, but the film lacked a certain factor that would help it to become a rewatchable guilty pleasure for future times to come. Drive Angry also knows exactly what it is, but unfortunately, what it is as not as much fun as it should be. That film knew exactly what it was and it did it well. I think Piranha was the kind of film where I could have written the exact same review and assign it either a 1 star or a 4 star rating (which is what I ended up doing). This is strange, but I am going to have to both judge this movie, while defending Piranha 3D. Highlighting is available in Article View.

I love taming a male and female tortoise because the next day I wake up, there is a whole army waiting for me. Consequently, once you go with big animals, they die once in for all.Īnother reason why it’s important is that more animals are like a wolfpack, they always win against bigger animals if they are more. They are still left with few and can breed more to come back. The main reason is that, although more animals are fragile and would die quickly. If you are new to the game, make sure that you are always going with more animals as compared to one. One of the most underlooked aspects of the game is animal quantity vs. RimWorld Tips Go With Many Animals As Compared To One Animals in RimWorld. Assign Zones To Avoid Animals Getting In Doors.Freeze Your Favourite Colonists when They Die.Go With Many Animals As Compared To One.Now without any further due, let’s jump in these RimWorld tips that would help you make a thriving colony. Just Started Playing RimWorld And Now Looking For Valuable Tips? This is the correct place that can help you make a striving colony. Subsequently, the best way to excel in this game is to play and read as much as you can. But, keep in mind that unlike other games, where the whole gameplay is just set of on a few options, RimWorld is kind of unlimited with features. Now, If you are looking for some beginner and advanced level RimWorld Tips, this guide will help you to some extent. Obviously, these tips aren’t that game-changing, but it only explains the depth of details this game has. Some additional tips include: The mood of the colonists highly impacts their output, making furniture can bring profits with a good craftsman, cowboy hats increase trading benefits and discounts, raiders take knowledge of your place when they escape.Īs a player, who has spent hundreds of hours playing RimWorld, I’ve to say that I’m still finding new features and things I never knew before.Players should build stone walls to get protection from a lot of dangers.Players can enhance their farming output by finding more rich soil to support the corps’ growth. Drugs can be best used for trading, and players should avoid their use in colonies as it causes addiction and lazy colonists.Also, use sterile tile as flooring, as it has positive cleanliness and improves room impressiveness. Players can assign zones to prevent animals from getting indoors and causing problems.Also, freeze favorite colonists’ corpses for future revival. Another great tip is to tame boars as soon as possible they are fast, resourceful, and can eat both meat and non-meat food. They can also build stone statues to boost beauty, improve mood and increase productivity. Players can go with many animals instead of one, as they are easier to breed and win against bigger animals.Players can take different steps to manage colonies more efficiently in Rimworld. Nicknamed the Side-loader by collectors, this was the production version of the Beach Bomb. The roof was also cut away and replaced by a full-length sunroof, to lower the center of gravity. Hot Wheels designers Howard Rees and Larry Wood modified the casting, extending the side fenders to accommodate the track width, as well as providing a new place on the vehicle to store each of the plastic surfboards. Unfortunately, testing showed that this early version (now known among collectors as the Rear-Loader Beach Bomb, or 'RLBB') was too narrow to roll effectively on Hot Wheels track or be powered by the Super Charger, and was too top-heavy to negotiate high-speed corners. During the fledgling Hot Wheels era, Mattel wanted to make sure that each of the cars could be used with any of the playsets and stunt track sets. The initial prototypes of the Beach Bomb were faithful to the shape of a real VW Type 2 "bus", and had two surfboards sticking out the back window, in a nod to the VW's perceived association with the surfing community and the slang term for a person who spends much time surfing - a ' beach bum'. Splittin' Image, Torero, Turbofire, and Twin Mill were part of the "Show & Go" series and are the very first original in-house designs by Hot Wheels. The success of the 1968 line was solidified and consolidated with the 1969 releases, with which Hot Wheels effectively established itself as the hottest brand of small toy car models in the USA. The Twin Mill was introduced in 1969 and was used to create the company's first full-scale replica car in 2001. Some of Hot Wheels' greatest cars, such as the Twin Mill and Splittin' Image, came from Ira Gilford's drawing board. Gil ford, who had just left Chrysler, quickly accepted the job of designing the next Hot Wheels models. When the company asked him to come back, he recommended a good friend, Ira Gil ford. Harry Bentley Bradley did not think that would be the case and had quit Mattel to go back to the car industry. The series completely disrupted the industry for small die-cast car models from 1968 onward, forcing the competition at Matchbox and elsewhere to completely rethink their concepts, and to scramble to try to recover lost ground. The Hot Wheels brand was a staggering success. Hot Wheels cars were designed to roll easily and at high speeds, which was a great innovation at the time. Hot Wheels' use of wide, hard-plastic tires created much less friction and tracked more smoothly than the narrow metal or plastic wheels used on contemporary Matchbox cars. Though it would be updated throughout the years, the original track set consists of a series of bright orange road sections (pieced together to form an oblong, circular race track), with one (or sometimes two) "superchargers" (faux service stations through which cars passed on the tracks, featuring battery-powered spinning wheels, which would propel the cars along the tracks). In addition to the cars themselves, Mattel produced a racing track set (sold separately). Bradley was from the car industry and had designed the body for the (full-sized) Dodge Deora concept car and the Custom Fleetside, (based on his own customized 1968 Chevrolet C-10 fleetside. The first one produced was a dark blue " Custom Camaro". There were sixteen castings released, eleven of them designed by Harry Bentley Bradley with assistance from Handler and Ryan. These were the first of the Red Line Series, named for the tires which had a red pin stripe on their sides. The first line of Hot Wheels Cars, known as The Original Sweet 16 was manufactured in 1967. He began producing the cars with assistance from fellow engineer Jack Ryan. Hot Wheels were originally conceived by Handler to be more like " hot rod" cars (i.e., customized/modified or even caricaturized or fantasy cars, often with big rear tires, Superchargers, flame paint-jobs, outlandish proportions, hood blowers, etc.), as compared to Matchbox cars which were generally small-scale models of production cars. Handler discovered his son Kenneth playing with Matchbox cars and decided to create a line to compete with Matchbox. The original Hot Wheels were made by Elliot Handler. Although Hot Wheels were originally intended to be for children and young adults, they have become popular with adult collectors, for whom limited edition models are now made available. Many automobile manufacturers have since licensed Hot Wheels to make scale models of their cars, allowing the use of original design blueprints and detailing. It was the primary competitor of Matchbox until Mattel bought Matchbox owner Tyco Toys in 1997. Hot Wheels is an American brand of scale model cars invented by Elliot Handler and introduced by his company Mattel on May 18, 1968. For other purposes, see Hot Wheels (disambiguation).
