To limit the chances of the pump clogging up due to debris and other particulates – this WAYNE battery backup sump pump features a top suction mechanism. The WAYNE WSS30VN runs on a 12-volt 75 AMP battery, which allows it to pump out 5,100 gallons of water per hour at zero feet. The battery can provide one million full cycles – a claim that has been authenticated by various failure analysts and found to be true. This WAYNE battery-backup sump pump has been rigorously tested, and the results are impressive. Included next in our battery-backup sump pump reviews is the WAYNE WSS30VN – undoubtedly one of the best-rated sump pumps you can buy. Best of all, it has a reasonable price point you get a lot more for what you pay. Also, this sump pump battery-backup system has an alarm feature that goes off every time there is a change in the system – you also have the option to mute it if required. The Superior Pump 92910 can seamlessly drive out water at the rate of 1,380 gallons per hour the best part is that water can be moved up at least 25 feet. Furthermore, it is designed to perfection with is a stainless steel shaft and a thermoplastic housing unit along with some copper parts – all are durable materials and can withstand all adversities.

2/23/2023 0 Comments Mapping property millumin![]() Each mapping element is attached with a semantic relation, for example equivalence. The output of matching is a mapping, namely a set of semantic correspondences between the two graphs. This is translated into the logical formula “red AND car”. For example, in case the folder “car” is under another folder “red” we can say that the meaning of the folder “car” is “red car” in this case. The formula codifies the meaning of the node, accounting for its position in the graph. These sentences are translated into a formal logical formula (according to an unambiguous, artificial language). The proposed technique works on lightweight ontologies, namely, tree structures where each node is labeled by a natural language sentence, for example in English. For example, applied to file systems, it can identify that a folder labeled “car” is semantically equivalent to another folder “automobile” because they are synonyms in English. classifications, databases, or XML schemas and ontologies, matching is an operator which identifies those nodes in the two structures that semantically correspond to one another. ![]() Given any two graph-like structures, e.g. Semantic matching has been proposed as a valid solution to the semantic heterogeneity problem, namely, supporting diversity in knowledge. Minimal mappings are the result of an advanced technique of semantic matching, a technique used in computer science to identify information which is semantically related. ![]() ( Learn how and when to remove this template message) ( September 2011) ( Learn how and when to remove this template message) It may require cleanup to comply with Wikipedia's content policies, particularly neutral point of view.

For more details, see the Postgres documentation on page layout, or a less formal article, particularly the section "How The Rows are Stored". This causes the performance of queries that need to read these values to get substantially worse. If the tuple is still too large, it stores the variable-length fields in a separate table using a mechanism called TOAST (The Oversized-Attribute Storage Technique). When a row is larger than this threshold, Postgres first tries to compress variable-length fields. The exact number is 2032 bytes: (8196 byte page - 24 byte page header - 4×4 byte item offsets) / 4, rounded down to 8 byte alignment (see heaptoast.h). It attempts to store a minimum of 4 tuples per page, which means a tuple has a maximum size of a bit less than 2 kiB. Still: it seems like something that might be worth investigating for the Postgres maintainers. This is large enough that it may hurt some workloads. For an SSD with a 75 µs random read latency and throughput of 3000 MiB/sec (approximate 2022 numbers), it would increase from about 77 µs to 95 µs, which is a 23% increase. If we assume a 200 MiB/sec transfer rate and a 5 ms seek time (approximately a 2022 data center hard drive), going from 8 kiB pages to 64 kiB pages would mean random reads would go from about 5.04 ms to 5.4 ms, or an increase of about 7%, which means this would likely be a performance win for any application with large rows. These benchmarks show that larger pages can be better for large rows, since it would increase the amount of storage before falling off this cliff. A rough rule of thumb is that smaller pages are better for workloads that read and write small values, but larger pages are likely better for queries that scan ranges. I suspect the 8 kiB page may be the wrong default these days. However, Postgres's row length limit is pretty low. This is a general database problem and not a Postgres problem: MySQL and others have their own performance cliffs for large values. This should reduce the performance penalty for compressed values. I didn't test it, but others have found it to use a bit more space but be signficantly faster ( 1, 2). If you are using Postgres 14 or later, you should use LZ4 compression. In cases where you need excellent query performance, you may want to consider trying to split large JSON values across multiple rows. Compressed values makes queries take about 2× more time, and queries for values stored in external TOAST tables take about 5× more time. Never use JSON because the performance is terrible. Queries on HSTORE values are slightly faster (~10-20%), so if performance is critical and string key/value pairs are sufficient, it is worth considering. Accessing JSONB values is about 2× slower than accessing a BYTEA column. ![]() It stores parsed JSON in a binary format, so queries are efficient. Most applications should use JSONB for schemaless data. My conclusion is that you should expect a 2-10× slower queries once a row gets larger than Postgres's 2 kiB limit. ![]() This article contains some quick-and-dirty benchmark results to explore how Postgres's performance changes for the "schemaless" data types when they become large. The same performance cliff applies to any variable-length types, like TEXT and BYTEA. Unfortunately, the performance of queries of all three gets substantially slower (2-10×) for values larger than about 2 kiB, due to how Postgres stores long variable-length data ( TOAST). Postgres supports three types for "schemaless" data: JSON (added in 9.2), JSONB (added in 9.4), and HSTORE (added in 8.2 as an extension). ![]() 2/23/2023 0 Comments Samsung ip camera utility download![]() ![]() This applies not only to IP cameras, and all devices operating in a computer network.

2/23/2023 0 Comments Squidoo money making![]() ![]() Oh well, live and learn, right? Instead of the $1.14 each lens was “worth” to me that month, they would each be worth close to $2.00 each – just from Squidoo shared revenue. If I had done that, I could have earned an easy extra $19. A rough guess-timate would be above an over-all lensrank of 45,000 to get at least the 2nd tier payout. If I knew then what I know now, I would ALWAYS make sure my lenses ranked in the top 60%. I also made a few bucks from Squidoo Amazon shared profits for sales made on my lenses.Īugust Squidoo Payment – Earnings from June – 54 Lenses = $61.64 I had 5 lenses make the top payout, 27 lenses earn the mid payout, 19 lenses make the bottom payout, and 2 lenses got paid na-da for being “WIP” lenses (not completed). The tiered-payout for this month on Squidoo was as follows:Īs you can see, the payouts went up dramatically which shows that Squidoo was doing well. Basically, if a lens on your dashboard has a green check next to it, you get paid for it. Lenses had to meet certain criteria in order to earn Squidoo shared revenue (and to also be available thru Squidoo search). However, this same month Squidoo also implemented the “Work in Progress” lens classification. In June, I created 20 more lenses bringing my total lens count to 54. The Squidoo payment in August was from my June earnings. July Squidoo Payment – May Earnings – 34 lenses = $39.47Įach lens now had a monthly “worth” to me of $1.16. I also had a few small amazon co-op sales from the Amazon module that Squidoo gives lensmasters to use. I had 4 lenses make the top-tier payout (mainly the ones that were created early in May), 19 lenses that received the mid-tier payout, and the rest got the lowest payout (mainly ones that were created the last week of May). In a nutshell, the top 33.3% of lenses according to lensrank will make the top payout, the middle 33.3% by lensrank will make the mid-tiered payout amount, and the bottom 33.3% will make the bottom tier payout.įor May Squidoo payouts, the payout amounts per tier were: Squidoo has a three-tiered payment structure for calculating how much each individual lens makes each month. By the end of May I had a total of 34 lenses on my dashboard – four from the previous month and created 30 more (yup, thats like creating a lens a day!) ![]() I read Squidoo Blueprint and finally learned how to create lenses. The Squidoo payment in July was for May earnings. 80Įach lens averaged a monthly “worth” to me of twenty cents each. June Squidoo Payment – April Earnings – 4 Lenses =. Honestly, not a single one of those lenses were any good, either □Įach lens earned me. I had a whopping grand total of four lenses in April. In June, I was paid for Squidoo co-op revenue I earned in April. For example earnings from May are paid out the first part of July, June earnings are paid in August, and now this payment in September will be for July earnings) (Just a quick reminder: Squidoo pays within 45 days after a month closes out. In a few days, I will receive my 4th payment for Squidoo earnings for the month of July. To date, I have been paid by Squidoo three times. Today, in this post, I want to focus entirely on direct income that is actually paid to me by Squidoo.

The bass has round-wound strings on it, but those may also be switched to flatwounds - as I find that combination to sound particularly good on Musicmaster basses! I may swap out the pickup for a reissue vintage Strat or Mustang pickup eventually, as these are much closer to the Mustang/Musicmaster guitar pickups that were used in original Musicmaster basses (yes - there are 6 polepieces under the plastic cover for ALL those Musicmaster basses!). ![]() The pickup is a bit different from the original pickup in that it has a bar magnet across the bottom of the pole-pieces (as is typical of many Fender Squier pickups) as opposed to just having magnetic polepieces. The bridge is a recent Bronco Bass bridge, as is the pickup - with rest of the parts (neckplate, knobs, strap-buttons) being standard reissue hardware. Those are Strat knobs on the controls in this picture - I replaced them with the proper Jazz Bass style knobs. I made the pickguard using an old hacked up Musicmaster Bass pickguard as a pattern, though I later realized I could have bought one from WD Music Products pretty cheaply. The neck was a straight-forward refret, using Fender's current "medium" guitar fretwire as opposed to the "jumbo" fretwire used on Fender's full-size basses from 1966 on. If anybody has some details on this, please let me know or post a comment ! I'm not sure what was used to finish 1965 through 1970 Mustangs and Musicmasters - but my 1966 Mustang Bass does not appear to have a topcoat on it and the color is a bit different from Dakota Red. These colors also did not have clear coats applied over them, so they do age slightly differently than typical Fender finishes - with more darkening and less yellowing. I believe that at least from 1970 on, these were fairly thin polyurethane finishes as opposed to acrylic and nitro lacquer finishes - so it may be that the red and blue were "offset" colors formulated in a different base. ![]() This family of instruments had their own formulations of blue and red - with the blue being a slightly darker and greyer variation on Daphne Blue and the red being a slightly darker version of Dakota Red. ![]() I decided NOT to do a clear coat over the color coat, in keeping with the style of original Musicmaster Bass finishes - though I will point out that Daphne Blue is not a "correct" color for Musicmaster (or Mustang) basses or guitars. I eventually tracked down a 1971 Musicmaster neck that had been defretted and a set of the fairly unique early Musicmaster Bass tuners.Īs is often the case - the large body plugs I had glued in when I repaired the body were showing their seam marks, so I ended up sanding the front and back faces of the body flat again and spraying a few more coats of Daphne Blue. The initial stages of rebuilding and refinishing the body are covered in this post. The body was a cheap ebay purchase - I think I paid $15 for it plus shipping. I started off with an early 70s poplar Fender Musicmaster Bass body that had been mercilessly routed for different pickups and then apparently broken in half and badly reglued together.
