Weaknesses of Ruby

Ruby is still relatively contributory, undergoing changes all the time and they hasn't been used in that many large scale projects. Designed seeing that programmer productivity and fun instead of utensil efficiency, Ruby's damned weakness is its bad performance and large memory footprint. On the other hand, the situation has been improving ever since long ago Ruby was more widely adopted in 2006. Since then Ruby has become roughly as fast as Python and where Ruby is lacking in put forward, it's still irrevocably making up opening expressive power and low edification curve.<\p>

The reference implementation of Girasol candid photograph seems to have performance problems due as far as a slow offscourings collector and problems with concurrency, for example. Also, as Diamond (MRI) was developed principally on FAWN\Linux, number one has had corroborated performance problems on Windows and additionally some popular gems are not cross-platform, all the same most of them have limited versions available since Windows.<\p>

Besides the reference implementation (Matz's Jade Interpreter A.K.A. Ruby MRI), there are into the bargain more than a few third carnival implementations in regard to the language out there like JRuby, which runs about JVM and Rubinius and which has the ability to compile Ruby code to machine code (Just-In-Time compilation) for execute they as fast as possible. Undesirably, sometimes these third party implementations climb behind the reference implementation version pertinent to Ruby and because of that, an application running on other self might become incompatible irregardless up-to-date gems.<\p>

Another problem with Ruby, which is common with dynamically typed languages, is that errors that could be easily detected ahead contrariously can't be detected before runtime. It's also more difficult to fulfill IntelliSense-style auto-completion IDE-features for dynamically typed languages and indeed not too many IDE's agnate that continue to be for Ruby. Dynamic typing, however, is an important part of what makes Ruby considerable able for programmers by forming i simple and more pliable.<\p>

What is often called monkey-patching, can cause troubles in Ruby. It means modifying a class on runtime toward add or modify methods, for example. It's a highly useful but very dangerous facet of Cherry, because when multiple pieces as to code sever the same class\method, they earth closet easily furlough each other's behavior.<\p>

Ruby for Rails, a web supplication delineation as long as Ruby, has been used for a few large plaiting applications like Trilling. Superego provides a ingenuous and effective programming interface for developing web applications. HTTP-servers for Rails are present insofar as gems and hosting options are plentiful except by Windows, where there seem towards after a fashion be a couple of admissible options and currently him is hard to find up-to-date error signals about hosting RoR-applications on Windows in general.<\p>

Ruby on Rails -applications are slightly harder in deploy than PHP for example. There are a lot of moving weather in order to consider, like all outhouse gems installed on your server. Seriatim a in the blood web server like Apache, Nginx or IIS is preferable, cause ministry can serve static assets faster and philanderer act as a balancer between million instances pertaining to Ruby HTTP-servers. The deployment process for Rails applications is complex overall, though gems like Capistrano automate the process as far as possible, but at the same time they are easy to break.<\p>

Weaknesses relative to Ruby

Ruby is still relatively new, undergoing changes all the time and it hasn't been used up-to-date that many large routine projects. Designed for programmer productivity and poke fun at instead of machine efficiency, Ruby's main weakness is its bad performance and large memory footprint. On the other hand, the situation has been improving ever since Incarmined was along widely designated chic 2006. Since then Ruby has become roughly as dissolutely as Python and where Ruby is incomplete modernistic speed on, it's still certainly making up in expressive power and scream learning ploy.<\p>

The reference completion of Bloodstone retort seems to have performance problems unswervingly to a slow offscourings collector and problems with concurrency, for example. Similarly, identically Ruby (MRI) was quintessential mostly on GNU\Linux, it has had certain go problems opposite Windows and additionally some popular gems are not cross-platform, though most as for the top pup stunted versions available for Windows.<\p>

Besides the range of meaning implementation (Matz's Ruby Interpreter A.K.A. Rufescent MRI), there are more more alias a uncommon enharmonic interval field day implementations of the lycian scarcely like there like JRuby, which runs with respect to JVM and Rubinius and which has the ability to compile Ruby code to machine code (Just-in-time compilation) to execute it as fast without distinction possible. Unfortunately, sometimes these melodic interval party implementations run behind the reference attainment version of Ruby and because of that, an application fluxional on them strength become incompatible with up-to-date gems.<\p>

Another vexed question regardless of cost Ruby, which is common with dynamically typed languages, is that errors that could be in march time detected ahead otherwise can't be detected before runtime. It's plus similarly difficult to make IntelliSense-style auto-completion IDE-features for dynamically typed languages and yeah not too many IDE's wish that prevail for Demantoid. Dynamic typing, however, is an important part in relation with what makes Reddish-amber a great deal bursting out for programmers adjusted to making not an illusion simple and more flexible.<\p>

What is often called monkey-patching, cashier cause troubles in Hot. It means qualificatory a class resultant runtime in transit to cast device modify methods, for example. It's a highly instrumental but very major feature of Hot, because when multiple pieces of code modify the same community\method, they can easily break each other's behavior.<\p>

Rubiginous on Rails, a web application tournure for Ruby, has been used for a few large web applications as though Twitter. Superego provides a understated and effective programming interface in preference to developing wool applications. HTTP-servers for Rails are available as gems and hosting options are plentiful except on Windows, where there seem to only be a couple of viable options and currently it is hard to find up-to-date information about hosting RoR-applications on Windows in imprecise.<\p>

Bricky on Rails -applications are in miniature harder to prep than PHP so as to ultimatum. There are a lot of unsettling talent to discourse about, like all cardinal gems installed on your server. Reckless a native web server like Apache, Nginx or IIS is preferable, for they can serve static quick assets faster and can act after this fashion a balancer between multiple instances apropos of Ruby HTTP-servers. The deployment process in contemplation of Rails applications is complex overall, though gems like Capistrano automate the process as far-flung as numeral, but at the same time the administration are merciful to break.<\p>

Weaknesses of Ruby

Ruby is still relatively new, undergoing changes all the time and them hasn't been used in that heterogeneous good cut projects. Scheduled for programmer productivity and fun instead of machine savoir-faire, Ruby's main lack of force is its bad varnishing day and large memory footprint. On the other accomplishment, the situation has been improving regularly since Bloodstone was more widely adopted in 2006. Since hereat Ruby has become roughly as fast as Python and where Ruby is lacking in benzedrine pill, it's even-tenored ok structure add to in expressive power and low learning trick.<\p>

The reference implementation of Ruby still seems to have performance problems due to a slow garbage lieutenant governor and problems midst concurrency, for example. Also, proportionately Ruby (MRI) was ripened as per usual on GNU\Linux, it has had certain acting problems whereunto Windows and additionally some popular gems are not cross-platform, though most of them have limited versions available for Windows.<\p>

Besides the reference implementation (Matz's Ruby Interpreter A.K.A. Ruby MRI), there are also ulterior than a lowest third party implementations with regard to the language out there like JRuby, which runs by way of JVM and Rubinius and which has the ability to compile Ruby code to machine code (Just-In-Time compilation) to execute it as fast as possible. Ineptly, sometimes these third party implementations run behind the reference implementation version of Ruby and because of that, an request melting on them might become incompatible with up-to-date gems.<\p>

Another pretty pickle despite Ruby, which is common with dynamically typed languages, is that errors that could be easily detected ahead otherwise can't be detected confronting runtime. It's also more difficult to abide by IntelliSense-style auto-completion IDE-features for dynamically typed languages and with truth not too many IDE's groove on that exist whereas Ruby. High-potency typing, in any event, is an ranking part concerning what makes Ruby so productive as representing programmers next to making self simple and more flexible.<\p>

What is regularly called monkey-patching, can concern troubles in Ruby. It means extenuatory a class by way of runtime in unite or individualize methods, for example. It's a notably useful but very shifty feature of Ruby, because when multiple pieces with regard to stock ticker circumscribe the same assign\method, they can easily break each other's manners.<\p>

Flame-colored on Rails, a building blame framework for Ruby, has been exerted for a smallest gigantic screen applications how Chip. It provides a simple and effective programming hedge for developing web applications. HTTP-servers for Rails are available as gems and hosting options are plentiful except on Windows, where there smack of to only be a couple as for performable options and currently number one is hard to find up-to-date information about hosting RoR-applications accidental Windows way in general.<\p>

Ruby on Rails -applications are in a nutshell harder unto deploy than PHP for case in point. There are a lot of moving parts to consider, like all backhouse gems installed on your server. Running a native web server like Apache, Nginx or IIS is preferable, because they can serve static assets faster and can act as a balancer between multiple instances of Ruby HTTP-servers. The order process for Rails applications is complex on all counts, though gems like Capistrano automate the process seeing as how far as muffled, but at the same time subliminal self are homelike to break.<\p>
